Liquid- cooled motorcycles have the potential for greater power at a given displacement, tighter tolerances, and longer operating life, whereas air- cooled motorcycles are potentially cheaper to purchase, less mechanically complex and are lighter. An air-cooled engine contracts and expands with its wider temperature range, requiring looser tolerances, and giving shorter engine life. The temperature range of an air-cooled two-stroke is even more extreme and component life even shorter than in an air-cooled four-stroke. As applied to motorcycles, two-stroke engines have some advantages over equivalent four-stroke engines: they are lighter, mechanically much simpler, and produce more power when operating at their best.

Cooling is required to remove excessive heat—over heating can cause engine failure, usually from wear (due to heat-induced failure of lubrication), cracking or warping. Two most common forms of engine cooling are air-cooled and water-cooled. Most modern automotive engines are both water and air- cooled, as the water/liquid-coolant is carried to air-cooled fins and/or fans, whereas larger engines may be singularly water-cooled as they are stationary and have a constant supply of water through water-mains or fresh-water, while most power tool engines and other small engines are air-cooled. Some engines (air or water-cooled) also have an oil cooler.

Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. Air-cooled engines are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units.

Cooling fans - (also referred to as "cooling tower fans") - These are axial fans, typically with large diameters, for low pressures and large volumes of airflow. Applications are in wet mechanical cooling towers, air- cooled steam condensers, air-cooled heat exchangers, radiators, or similar air-cooled applications. Mixed-flow fans - The gas flow patterns these fans produce resemble a combination of axial and centrifugal patterns, although the fan wheels often appear similar to centrifugal wheels. There are various types of mixed-flow fans, including gas-tight high-pressure fans and blowers.

Air-cooled machines are directly cooled by ambient air being mechanically circulated directly through the machine's condenser coil to expel heat to the atmosphere. Evaporative cooled machines are similar, except they implement a mist of water over the condenser coil to aid in condenser cooling, making the machine more efficient than a traditional air-cooled machine. No remote cooling tower is typically required with either of these types of packaged air-cooled or evaporatively cooled chillers. Where available, cold water readily available in nearby water bodies might be used directly for cooling, replace or supplement cooling towers.

The coolant used in many liquid-cooled engines must be renewed periodically, and can freeze at ordinary temperatures thus causing permanent engine damage when it expands. Air-cooled engines do not require coolant service, and do not suffer damage from freezing, two commonly cited advantages for air-cooled engines. However, coolant based on propylene glycol is liquid to −55 °C, colder than is encountered by many engines; shrinks slightly when it crystallizes, thus avoiding damage; and has a service life over 10,000 hours, essentially the lifetime of many engines. It is usually more difficult to achieve either low emissions or low noise from an air-cooled engine, two more reasons most road vehicles use liquid-cooled engines.

The biggest change to the Richmond occurred in 1910, when the engine became water- cooled instead of air-cooled. A six-cylinder model was offered from 1914 till 1916, with outputs rising from 45 hp to 50 hp. Horsepower for the air-cooled fours ranged from 20 to 30, while the water-cooled engines produced 22.5 to 40 hp.

The Maxim gun design was provided with water cooling, giving it the ability to maintain its rate of fire for far longer than air-cooled guns. The disadvantage of this was that it made the gun less flexible in attack than the lighter air-cooled weapons, being heavier and more complex, and requiring a supply of water. Trials demonstrated that the Maxim could fire 600 rounds per minute. Compared to modern machine guns, the Maxim was heavy, bulky, and awkward.

Two slower, lower-cost air-cooled versions, the ETA-10Q and ETA-10P (code named "Piper") were also marketed.Pricing for the air-cooled systems began at a then unheard of $1,000,000. In fact, they could be purchased and operated at a lower cost than the cost to operate and maintain a low end Cray 1 or Cray-XMP. What set apart ETA Systems supercomputers and the Cray system was their ability to expand primary memory far beyond that of the Cray machines.

The 1923 Chevrolet Series M Copper-Cooled was an automobile made to be completely air-cooled by Chevrolet in 1923. It was designed by Charles F. Kettering, head engineer of Delco, the General Motors research division wing in Dayton, Ohio. The automobile used a body style from its predecessor, but incorporated an air-cooled engine. Air cooling, as opposed to water-based cooling, was much more practical in a sense because it did not require a radiator, nor the piping that came with it.

This is due to heat rejection at or near the air's wet-bulb temperature rather than the higher, sometimes much higher, dry-bulb temperature. Evaporatively cooled chillers offer higher efficiencies than air- cooled chillers but lower than water-cooled chillers. Water-cooled chillers are typically intended for indoor installation and operation, and are cooled by a separate condenser water loop and connected to outdoor cooling towers to expel heat to the atmosphere. Air-cooled and evaporative cooled chillers are intended for outdoor installation and operation.

The Type 100 was a conventional air-cooled radial engine with overhead valves, operated by push-rods and rockers. Accessories were mounted on the rear crankcase plate and the propeller was driven directly, with no reduction gearing.

Next came a locomotive from Berg & Co. Mek. Verkstad in Lindesberg (Bergbolagen, BB) in 1939. It had a small air-cooled petrol engine, which was replaced in the same year by a two-cylinder Pentamotor with transmission.

A common mistake was the idea that the air-cooled radial engine would benefit most, because its fins ran hotter than the radiator of a liquid-cooled engine, with the mistake persisting even as late as 1949.

1909 saw radial engine forms rise to significance. The air-cooled Anzani 3-cylinder semi-radial or fan engine of 1909 (also built in a true, 120° cylinder angle radial form) developed only 25 hp (16 kW) but was much lighter than the liquid-cooled Antoinette, and was chosen by Louis Blériot for his cross- Channel flight. A major advance came with the introduction of the Seguin brothers' Gnome Omega seven-cylinder, air-cooled rotary engine, exhibited at the Paris Aero Salon 1n 1908 and first fitted to an aircraft in 1909.

Ignition of the fuel mixture always takes place in the same part of Wankel engines, inducing thermal dilatation disparities that reduce power output, impair fuel economy, and accelerate wear. SAE paper 2014-01-2160, by Wei Wu et al., describes: 'A Heat Pipe Assisted Air-Cooled Rotary Wankel Engine for Improved Durability, Power and Efficiency', they obtained a reduction in top engine temperature from 231 °C to 129 °C, and the temperature difference reduced from 159 °C to 18 °C for a typical small-chamber-displacement air-cooled unmanned aerial vehicle engine.

A central chilled water plant using air-cooled chillers, water-cooled chillers are cooled by a cooling tower Central cooling plants are used to condition large commercial, industrial, or campus loads. At larger scales, the ductwork required to move conditioned air to and from the plant would be impractically large, so an intermediate fluid such as chilled water is used instead. The plant circulates cold water to terminal chilled water devices such as air handlers or fan/coil units. The plant often consists of a chiller, which may be water or air cooled.

Cloud Dancer I rotor hub The Cloud Dancer I features a single main rotor, a single-seat enclosed cockpit with a bubble canopy, tricycle landing gear with wheel pants and a twin cylinder, air-cooled Hirth two stroke engine mounted in pusher configuration. The twin-cylinder air-cooled in-line, two stroke, aircraft engine Hirth 3203 has also been employed. The aircraft fuselage and tail are made from aluminum and Kevlar composites. Its diameter rotor has a chord of and is equipped with a pre- rotator with an electromagnetic clutch and Cardan drive.

With the Briggs & Stratton engine and Pico L wing the aircraft has an empty weight of and a gross weight of , giving a useful load of . With full fuel of the payload is . A number of different wings can be fitted to the basic carriage, including the standard area Bautek Bico and the area Bautek Pico L, which is only used with the higher output Briggs & Stratton powerplant.

The Kawasaki Gpz305 was a twin cylinder air-cooled SOHC four-stroke motorcycle, produced in 1983 to 1994 by Kawasaki in Japan. The model evolved from the earlier ER250 model and used an overbored version of the 249 cc engine first produced in 1979. Kawasaki gave this model the "Gpz" nomenclature to add to its expanding air-cooled sports bike range, and was marketed as a sports machine. It originally had chain final drive but in 1983 it had a new Kevlar belt final drive first seen on Kawasaki's American styled cruisers.

The first version of the K3M offered to the Imperial Japanese Navy Air Service was prone to stability problems, and more importantly, problems with the water-cooled Mitsubishi-built Hispano-Suiza 8A eight-cylinder liquid-cooled engine. The improved K3M2 used a Hitachi Amakaze 11 nine-cylinder air-cooled radial engine, rated at for take-off and at sea level. The first K3M2 production examples entered service in 1932 as the Navy Type 90 Crew Trainer. It was superseded in production with the K3M3, using a Nakajima Kotobuki air-cooled engine.

The Navy Type 90 Crew Trainer was primarily a land-based aircraft; however, a few were fitted with floats. The Imperial Japanese Army Air Force had an interest in the aircraft as part of its modernization program, and as a potential supplement to the Nakajima Ki-6. Two examples were acquired and tested, and the airframe was given the designation of Ki-7. One prototype used a Mitsubishi Type 92 nine-cylinder air-cooled radial engine and the other a Nakajima Kotobuki nine-cylinder air- cooled radial engine.

Longitudinal circulation, on the other hand, comes about because the ocean has a higher specific heat capacity than land (and also thermal conductivity, allowing the heat to penetrate further beneath the surface ) and thereby absorbs and releases more heat, but the temperature changes less than land. This brings the sea breeze, air cooled by the water, ashore in the day, and carries the land breeze, air cooled by contact with the ground, out to sea during the night. Longitudinal circulation consists of two cells, the Walker circulation and El Niño / Southern Oscillation.

The outer panels were braced from the lower fuselage longerons by parallel pairs of struts to the spars which ran through the outer engine mountings. The engines were further braced with central struts to the upper longerons. Ospreys were fitted with at least three engine types. The prototype, as well as several later examples, had upright, air-cooled four cylinder Cirrus III engines and were designated Osprey Cs. Others had either inverted, air-cooled four cylinder Menasco B-4 or its larger capacity, development, the Menasco C-4.

The SP2 was built on the frame of a Variant, with the same Volkswagen air-cooled engine, but upgraded to 1,700 cc. It developed , propelling the car from 0-60 mph (97 km/h) in around 16 seconds according to period tests and to a top speed of 160 km/h (100 mph). Fuel economy is . When the car was presented, it quickly drew media attention, with its many improvements over the local "air cooled" VW line, an impressive interior, its many extra features and its superb finishing.

1988 Classic air cooled engine While its engine was revolutionary, in other respects, such as appearance, suspension and brakes, the Norton Classic was a conventional twin-shock roadster. The fork stanchions were protected by rubber gaiters; and a full enclosure protected the final-drive chain. The air-cooled Classic was lighter and more powerful than its only Wankel competitor in production, the over- complicated single-rotor Suzuki RE-5 motorcycle (which had liquid-cooled jackets and an oil-cooled rotor). The Classic was discontinued after a limited production run of only 100 motorcycles,Salvadori, Clement.

Norton Classic with twin-rotor Wankel engine The Norton Classic was a motorcycle whose air- cooled twin-rotor Wankel engine was developed by David Garside at BSA.The Wankel Rotary Engine: A History By John B. Hege page 137, Wankel engines run very hot, so Garside gave this air-cooled motor additional interior air- cooling. Air was drawn through a forward-facing filter situated to provide a ram air effect. This air passed through the interior of the rotors and then into a large pressed-steel plenum before entering the combustion chambers via twin carburettors.

Air cooled clothing is a term for clothing that actively cools down the wearer. It has primarily been used by workers in areas where air conditioning systems cannot be easily installed, such as tunnels and underground construction sites. Air-cooled clothing on the market does not operate by actually cooling down the air, as a room AC unit does. Instead, it increases the natural body cooling of the wearer by blowing air and sometimes water vapor around the body, decreasing skin temperature by the evaporation of sweat and vapor.

Patents for air cooled clothing have been around for years, but few products have actually made it to market. Hiroshi Ichigawa, a former Sony engineer spent 6 years to develop Kuchofuku, or "air-conditioned clothing" and launched his company in 2004 to manufacture and sell it. He first developed the water cooling system, but changed it to the air cooling system later because it was too uncomfortable to feel wet cloth. Another company that brought air conditioned shirts to market is Octocool, which is an online distributor of air cooled clothes.

The Tatra 613 was a large luxury rear wheel driven car with rear mounted air- cooled engine manufactured by Czechoslovak manufacturer Tatra from the 1970s to the 1990s, as a replacement for the Tatra 603 series. It featured an all- new body styled by Vignale of Italy and used a dohc air-cooled 3.5 litre V8 engine with . Later injection versions reached , with a maximum speed of . The design was updated a further five times until being replaced by the Tatra 700 in 1996, itself a restyled T613-5.

The company first tried the Lycoming aircraft engine, but it would not fit in the car's rear engine compartment. An air- cooled flat-6 engine, the O-335 made by Air Cooled Motors (and originally intended for the Bell 47), fit, and its pleased Tucker. He purchased four samples for $5,000 each, and his engineers converted the engine to water cooling (a decision that has puzzled historians ever since). The Franklin engine was heavily modified by Tucker's engineers, including Eddie Offutt and Tucker's son Preston, Jr. at his Ypsilanti machine shop.

Surface condenser A surface condenser is a commonly used term for a water- cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. These condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure. Where cooling water is in short supply, an air-cooled condenser is often used. An air-cooled condenser is however, significantly more expensive and cannot achieve as low a steam turbine exhaust pressure (and temperature) as a water-cooled surface condenser.

Mercury arc valves with grading electrodes of this type were developed up to voltage ratings of 150 kV. However, the tall porcelain column required to house the grading electrodes was more difficult to cool than the steel tank at cathode potential, so the usable current rating was limited to about 200-300 A per anode. Therefore, Mercury arc valves for HVDC were often constructed with four or six anode columns in parallel. The anode columns were always air-cooled, with the cathode tanks either water- cooled or air-cooled.

The Citroën Axel was a supermini automobile produced between 1984 and 1988 and developed in co-operation by Citroën of France and Oltcit, a joint venture company with the Romanian government. The Axel was a rebadged version of the small Oltcit Club hatchback. Three specifications were available: Axel 11, Axel 11R and Axel 12 TRS. They were powered by the air-cooled engines from the Citroën GS/GSA; the air-cooled flat-twin engine from the Citroën Visa used in the Romanian-market Oltcit Special was not installed in the export-only Citroën Axel.

The Minica Van, based on the 1969 Minica 70, lived a long life until eventually replaced by the Minica Econo in 1981. Starting with the air-cooled A100V, it was replaced by the water-cooled A101V in late 1972. There was no A102 nor A103 van, as the A101V remained available only with the air-cooled "Red" two-stroke engine until the introduction of the Minica 5 Van (A104V) in March 1976. This was soon followed by the bigger engined "Minica 55 Van" (A105V), which has the newer 2G23 engine with at 5500 rpm.

Most parts are not interchangeable with earlier engines. While the VW 412 was discontinued in 1974 when sales dropped, its engine continued as the VW Bus power plant for Volkswagen Type 2s produced from 1972 to 1979: it continued in modified form in the later Vanagon which was air-cooled from 1980 until mid-1983. 1.7 Litre – The Type 4 engine was also used on the Volkswagen version of the Porsche 914. Volkswagen versions originally came with an fuel- injected 1.7-litre flat-4 engine based on the Volkswagen air-cooled engine.

The heavier designs continued to be used throughout World War II and into the 1960s, but were gradually phased out in favor of air-cooled designs. The mediums were now used both as medium machine guns while mounted on tripods and as light machine guns while mounted on bipods. This was possible in part because a heavy, static MG position was not a very effective tactic in vehicle-centered warfare, and the significantly lighter air-cooled designs could nearly match the capabilities of the water-cooled versions. Gatling-type machine guns such as the Minigun and GShG-7.62 reappeared after World War II. These are typically mounted on ships and helicopters because of their weight and large ammunition requirements (due to their extremely high rate of fire.) The need for sustained automatic fire on the ground, however, is now nearly entirely filled by air-cooled medium machine guns.

The Victorian Railways used a variety of air-cooled and iced wagons or refrigerated vans for the transport of all manner of goods. This page covers the history and development of the various classes, and how they changed through their lives.

234 Puma. In the latter stages of World War II Tatra was instrumental in the development of air-cooled diesel engines for German tanks. In late 1944 General Heinz Guderian ordered that production of the Type 38(t) Hetzer tank be modified to incorporate a Tatra Type 928 V-8 air-cooled diesel engine, though this order was delayed so production could continue uninterrupted. After the war the T111 contributed heavily to the rebuilding effort in Central and Eastern Europe and a memorial was built at Magadan, Siberia for its exploits in the Far East of the USSR.Tatratech.wz.

Two HVAC cooling towers on the rooftop of a shopping center (Darmstadt, Hesse, Germany) Cell of a cross-flow type cooling tower with fill material, and circulating water visible. An HVAC (heating, ventilating, and air conditioning) cooling tower is used to dispose of ("reject") unwanted heat from a chiller. Water-cooled chillers are normally more energy efficient than air-cooled chillers due to heat rejection to tower water at or near wet-bulb temperatures. Air-cooled chillers must reject heat at the higher dry-bulb temperature, and thus have a lower average reverse- Carnot cycle effectiveness.

The R-4360 was a 28-cylinder four-row air-cooled radial engine. Each row of seven air-cooled cylinders possessed a slight angular offset from the previous, forming a semi-helical arrangement to facilitate effective airflow cooling of the cylinder rows behind them, inspiring the engine's "corncob" nickname. A mechanical supercharger geared at 6.374:1 ratio to engine speed provided forced induction, while the propeller was geared at 0.375:1 so that the tips did not reach inefficient supersonic speeds. The engine was a technological challenge and the first product from Pratt and Whitney's new plant outside Kansas City, Missouri.

Rear of pre-facelift Fiat Panda Mechanically the first Pandas shared engines and transmissions with the Fiat 127 and, in certain territories, the air-cooled 652 cc two-cylinder powerplant of the Fiat 126. Rear suspension used a solid axle suspended on leaf springs. Later versions added mechanical improvements while retaining a robust simplicity throughout its model life. Launch models included the Panda 30, powered by a longitudinally-mounted air cooled 652 cc straight-two- cylinder engine derived from the 126, and the Panda 45, with a transversely- mounted water cooled 903 cc (FIAT 100 series) four-cylinder from the 127.

The Kawasaki Zephyr is a range of retro-styled naked superbikes made in the 1990s in Kawasaki's Z series. All models have transverse air-cooled dual overhead camshaft inline-four engines. There were a number of Zephyr models, in four engine capacities, . The 400 was produced for the Japan market starting in 1989. Zephyr styling is roughly based on the old Kawasaki Z1, with twin shock rear suspension, a relatively upright riding position and air- cooled power units. The 400, 550 and 750 engines were developed from the old Z400/500/550/650/750/900 series.

One being the space needed for the fins and the other being oil leaks, which were very hazardous to air cooled systems. Oil leaks in an air cooled system were fire hazards, as well as health safety hazards because when oil leaks onto the hot metal surfaces of the engine it creates smoke and could ignite causing severe damage to the automobile, and its occupants. Also, because of the burnt layer of oil, cooling would be drastically decreased. Kettering understood these concerns and continued to work on ways that would minimize the possibility of an oil leak on the hot cylinders.

The C.362 was powered by a high compression ratio version of the Renault Bengali air-cooled inverted four-cylinder inline engine developing while the C.366 was powered by a Regnier air-cooled inverted 6-cylinder inline. It had been intended to use this engine for all three aircraft, but development problems with it resulted in the use of the Renault engine in two of the airframes that had been constructed. The type was developed into the Caudron C.450 and C.460 racers, which won the Coupe Deutsch de la Meurthe in 1934, 1935 and 1936.

During the 1990s, Porsche was facing financial troubles and rumours of a proposed takeover were being spread. The signature air-cooled flat-6 of the 911 was reaching the limits of its potential as made evident by the 993. Stricter emissions regulations worldwide further forced Porsche to think of a replacement of the air-cooled unit. In order to improve manufacturing processes, Porsche took the aid of leading Japanese car manufacturer Toyota whose consultants would assist in the overhaul of the Zuffenhausen manufacturing facility introducing mass production techniques which would allow Porsche to carry out production processes more efficiently.

Both the GT3 and GT2 were available only with a 6-speed manual transmission. The Turbo, GT2 and GT3 models use the Aluminum crankcase of the air-cooled 911 with its true dry sump oiling system. The six separate individual Nikasil lined cylinders in this engine are covered with two separately installed water jackets each covering a bank of 3 cylinders on each side of the engine, thus adding water cooling to a crankcase originally designed for air-cooled cylinders (the standard 996 Carrera engine has the cylinders and water jackets cast together with the crankcase).

The 360 (referring to the 354 cc engine) had a two-cylinder engine producing 18 horsepower. Originally introduced as a two-door sedan, it was also built in light panel van and pickup truck versions, replacing the unrefined and outdated Cony Guppy and the similar Giant 360. Instead of an air-cooled two cylinder engine from the previous model, which was seen as outdated and unrefined, a new lighter air-cooled four cylinder engine producing 18 hp was placed in the 360; power went up to 20 hp after 1967. The vehicle was a technical oddity in early-1960s Japan.

Albert S. (Al) Menasco organized the Menasco Motors Company in 1926 to convert WWI surplus Salmson Z-9 water-cooled nine-cylinder radials into air-cooled engines for private use. His association with John K. (Jack) Northrop and his flying wing project in the late 1920s convinced him of the need for a new configuration of aircraft engine: an inverted in-line air-cooled layout that would have the propeller shaft on top for better ground clearance and improved pilot vision.Parker, Dana T. Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II, pp. 121-124, Cypress, CA, 2013.

The 1936 Tatra T97 pioneered the rear-engined, air-cooled flat-four, backbone chassis layout (later used by the Volkswagen Beetle), and at the same time, though unrelated, came the Steyr 50 from Austria, sporting a front boxer 4 engine with rear wheel drive. Also in 1936, English company Jowett expanded its model range from flat-twin engines to also include flat-four engines. Production of Jowett flat-four engines continued until 1954, when the Jowett Javelin saloon and Jowett Jupiter sports models ended production. The longest production flat-four engine is the Volkswagen air-cooled engine, which was produced from 1938 until 2006 and was most famously used in the rear-engined 1938-2006 Volkswagen Beetle and 1950-1990 Volkswagen Transporter. This air- cooled engine was designed by Porsche and was also used in the 1948-1965 Porsche 356, 1953-1956 Porsche 550, 1965–1969 Porsche 912 and 1969-1976 Porsche 914.

Where reliability is of utmost importance, as in aircraft, it may be a good trade-off to give up efficiency, longevity (interval between engine rebuilds), and quietness in order to achieve slightly higher reliability; the consequences of a broken airplane engine are so severe, even a slight increase in reliability is worth giving up other good properties to achieve it. Air-cooled and liquid-cooled engines are both used commonly. Each principle has advantages and disadvantages, and particular applications may favor one over the other. For example, most cars and trucks use liquid-cooled engines, while many small airplane and low-cost engines are air-cooled.

The powerplant is a single cylinder, air-cooled four-stroke, Bailey V4 200 engine, with the single cylinder, air-cooled, two-stroke Simonini Mini-3 or Simonini Mini-2 engines optional.

A number of different wings can be fitted to the basic carriage, including Aeros Discus 15T, 14 and 12 as well as the Aeros Combat 12T.

Rentschler left the Army convinced that future aircraft would require lighter-weight engines with much greater power and higher reliability. His proposed design of an air-cooled engine flew in the face of conventional wisdom, which held that heavier liquid-cooled engines would power the future of aviation. Rentschler became president of the Wright Aeronautical Corporation and pressed for research into his idea. Unable to convince his board of directors, largely composed of investment bankers with little aviation knowledge, he resigned in 1924, and supported by old friend and Wright chief engineer George J. Mead, he developed a proposal for a high- powered air-cooled aircraft engine for the U.S. Navy.

VW Type 2 / T3 Transporter The Volkswagen Type 2 (T3), (and occasionally T25 within the UK, but technically incorrect) or Vanagon in the United States, the T3 platform was introduced in 1979, and was one of the last new Volkswagen platforms to use an air-cooled engine. The Volkswagen air-cooled engine was phased out for a water-cooled boxer engine (still rear-mounted) in 1983. Compared to its predecessor the T2, the T3 was larger and heavier, with square corners replacing the rounded edges of the older models. The T3 is sometimes called "the wedge" by enthusiasts to differentiate it from earlier Kombis.

Early in the development the Navy requested better altitude performance and, in view of unsatisfactory progress in the development of the XH-2470 engine, Curtiss adapted the design of the aircraft around the new turbocharged Wright R-3350 Duplex-Cyclone air-cooled radial engine. The aircraft equipped with this eighteen-cylinder twin-row radial air- cooled engine and three bladed contra-rotating propellers was designated the XF14C-2. The XF14C-1 was canceled. Also, looking at the problems of operation at altitudes of about 40,000 feet (12,000 m), the Navy also initiated work on a third version with a pressurized cockpit designated the XF14C-3.

The prototype W501G was installed at The City of Lakeland (FL) McIntosh station and was first synchronized to the grid in April, 1999, shortly after the Siemens acquisition of Westinghouse PGBU. For more details on the W501G and the McIntosh plant see Modern Power Systems, Jan. 2001. (It is noted that current Siemens gas turbine product offerings do not include the "G", as it was replaced, first by the advanced air-cooled "F" and then by the 300 MW "H". MHI continues to offer their "M501G" – both steam-cooled and air-cooled, rated at around 270 MW, as well as their new 300 MW-plus model M501J).

Engine power and aircraft performance increased steadily throughout the war, with liquid-cooled inline and vee engines competing with air-cooled radials much as they had competed with air-cooled rotary types in the First War. As an example, at the start of the war the Rolls-Royce Merlin III liquid-cooled V-12 engine developed just 1,000 hp while at the end its derivative the Rolls-Royce Griffon 61 offered 2,035 hp.Gingell (1976), Page 47. In the early stages of the war German fighters, especially the Messerschmitt Bf 109, were very fast and maneuverable and had the advantage over the British types of a fuel- injected engine.

It was technically equivalent to the West German Lloyd automobile, a similarly sized car with an air-cooled, two-cylinder four-stroke engine. The Trabant had a front, transversely mounted engine and front-wheel drive in an era when many European cars were using rear-mounted engines or front-mounted engines with rear-wheel drive. Its greatest drawback was its largely unchanged production; the car's two-stroke engine made it obsolete by the 1970s, limiting exports to Western Europe. The Trabant's air-cooled, engine—upgraded to in 1962–63—was derived from a pre-war DKW design with minor alterations during its production run.

Two leather padded rings on the left and on the right sides of the breech of the weapon rested on the knees of the machine gunner sitting behind it and permitted sweeping fire. The machine gun MG 94 was chambered for the 7.5x53.5 mm GP 90 cartridge and was later, along other minor technical modifications, adapted for firing the more powerful 7.5x55 mm GP 11 cartridge. Six MG 94 had their water-cooling mantles drilled and cut open, making these guns air-cooled and thus water-free and lighter for use as aircraft machine guns. These 6 MG 94 air-cooled guns were taken out of service in 1944.

George Brough considered the four-cylinder engine ideal for a motorcycle, given its smooth running and potential for greater horsepower than a single or twin-cylinder engine of the same capacity. Brough Superior had already revealed two prototype 4-cylinder machines before 1932, using an air-cooled sidevalve V-4 built in-house (1927), and an air-cooled inline sidevalve 4 developed by Motosacoche (1928). While these prototypes were never built in series, they generated tremendous attention at shows and in the press . In 1930, George Brough considered using an engine already in production, in this case the well-developed Austin 4-cylinder sidevalve, water-cooled motor of 747cc.

The 1000DS was a two valve dual spark SuperSport. The 1000DS motor has a 992 cc air-cooled 90° V-Twin, based on Ducati's existing liquid and air-cooled engines, with twin-spark plug heads, pressure fed plain camshaft bearings, redesigned crankshaft, higher oil pressure and volume, and new alloy clutch basket, drive and driven plates. The Multistrada 1000DS uses Ducati's signature trellis frame with fully adjustable 160 mm travel Showa forks up front, and a single-sided swingarm, with an Öhlins fully adjustable rear shock coupled with a rising rate, height-adjustable suspension system at the rear. Brembo "Serie Oro" calipers used front and rear.

It is difficult to make generalizations about air-cooled and liquid-cooled engines. Air-cooled diesel engines are chosen for reliability even in extreme heat, because air-cooling would be simpler and more effective at coping with the extremes of temperatures during the depths of winter and height of summer, than water cooling systems, and are often used in situations where the engine runs unattended for months at a time. Similarly, it is usually desirable to minimize the number of heat transfer stages in order to maximize the temperature difference at each stage. However, Detroit Diesel two-stroke cycle engines commonly use oil cooled by water, with the water in turn cooled by air.

Menestrels have been powered by a variety of engines, mostly variants of the Volkswagen flat-4 engine. Early versions of these were entirely air-cooled, but more recently the cylinder heads have been water- cooled. Some early Menestrels with air-cooled engines have exposed cylinder heads for cooling but more have semi-cylindrical, bulged fairings to enclose them. The water-cooled engines used in the Menestrel II have cowlings which enclose the whole engine without additional fairings, with an air intake behind the propeller. The first HN 433 Menestrel had a 22 kW (30 hp) 1.3 L engine; later HN 433s have had engines in the 22-37 kW (30-50 hp) power range.

The 1911 model was powered by a JAP 964cc 7 hp V twin air-cooled engine driving the rear axle via a 2 speed gearbox and chain drive. A review of the 1913 model,The Motor Cycle and Cycle Car Show at Olympia, The Automotor Journal, 30 November 1912, p1451 on display at the 1912 Motor Cycle and Cycle Car Show at Olympia, stated that it was one of the first cycle cars made in this country, and that it had benefitted from the production of only one model for the past 2 years. The emphasis was on its ability as a touring car rather than for sporting purposes. The engine was an air-cooled 8 h.p.

Many of the competitors machines in New South Wales have reached a new level in mechanical performance and presentation. As the rules developed the choice of machines expanded to encompass two classes. The original race bikes remained as Superlites and a new class was developed, Motolites. This new class allows the choice of an engine type and capacity and unlimited development of any other part of the machine. The capacity sizes are: 111 cc Air-cooled 2 strokes, 85 cc Water-cooled 2 strokes, 159 cc 4-valve single- cylinder 4-stroke, 185 cc 2-valve single-cylinder 4-stroke, 159 cc 2-valve twin-cylinder 4-stroke, 200 cc 2-valve air-cooled single-cylinder 4-stroke.

The Citroën 2CV (, lit. "two steam horses", "two tax horsepower") is an air- cooled front-engine, front-wheel-drive economy car introduced at the 1948 Paris Mondial de l'Automobile and manufactured by Citroën for model years 1948–1990. Conceived by Citroën Vice-President Pierre Boulanger to help motorise the large number of farmers still using horses and carts in 1930s France, the 2CV has a combination of innovative engineering and utilitarian, straightforward metal bodywork—initially corrugated for added strength without added weight. The 2CV featured low cost, simplicity of overall maintenance, an easily serviced air-cooled engine (originally offering 9 hp), low fuel consumption, and an extremely long-travel suspension offering a soft ride and light off-road capability.

Volkswagen T1 13 window "Kombi" microbus Volkswagen T1 Single-cab utility pickup The first generation of the Volkswagen Type 2 with the split windshield, informally called the Microbus, Splitscreen, or Splittie among modern fans, was produced from 8 March 1950 through the end of the 1967 model year. From 1950 to 1956, the T1 (not called that at the time) was built in Wolfsburg; from 1956, it was built at the completely new Transporter factory in Hanover. Like the Beetle, the first Transporters used the 1100 Volkswagen air-cooled engine, an , DIN-rated , air-cooled flat-four- cylinder 'boxer' engine mounted in the rear. This was upgraded to the 1200 – an in 1953.

A 1980 Volkswagen Combi in Mexico City T2 production began in 1970 at the Puebla assembly factory. Offered initially only as a nine-passenger version called the Volkswagen Combi (Kombi in Brazil), and from 1973 also its cargo van version called the Volkswagen Panel, both variants were fitted with the 1.5 L air-cooled boxer engine and four-speed manual gearbox. In 1974, the 1.6 L boxer engine replaced the 1.5 previous one, and production continued this way up to 1987. In 1987, the water-cooled 1.8 L inline four-cylinder engine replaced the air-cooled 1.6 L. This new model is recognisable by its black grille (for its engine coolant radiator), bumpers and moldings.

Light variants of the M60 machine gun (foreground) and a M240B (back) in use with the US Navy, 2010. The heavier water-cooled designs continued to be used throughout World War II and into the 1960s, but were gradually phased out in favor of the lighter air-cooled designs. The mediums are now used both as heavy machine guns, while mounted on tripods, and as light machine guns, while mounted on bipods. This was possible, in part, because a heavy static MG position was not a very effective tactic in vehicle centered warfare, and the lighter air- cooled designs could nearly match the capabilities of water-cooled designs with a combination of other, lighter cooling features.

In 1941 the US Navy requested a better-performing carrier- based fighter plane, to be powered by the proposed high performance 24-cylinder liquid cooled Lycoming XH-2470 Hyper engine. This was an unusual step for the Navy, which had been adamant to that time that all its aircraft use air-cooled radial engines. On June 30, 1941 a contract for two prototype aircraft, designated the XF14C-1, was awarded to the Curtiss-Wright company. On the same date prototype development contracts were also awarded to Grumman Aircraft Engineering Corporation for the single-engine XF6F-1 and the twin engine XF7F-1, both of which would use air-cooled Pratt & Whitney R-2800 Double Wasp radial engines.

Porsche's signature designs have, from the beginning, featured air-cooled rear-engine configurations (like the Beetle), rare for other car manufacturers, but producing automobiles that are very well balanced. In 1964, after a fair amount of success in motor- racing with various models including the 550 Spyder, and with the 356 needing a major re-design, the company launched the Porsche 911: another air-cooled, rear-engined sports car, this time with a six-cylinder "boxer" engine. The team to lay out the body shell design was led by Ferry Porsche's eldest son, Ferdinand Alexander Porsche (F. A.). The design phase for the 911 caused internal problems with Erwin Komenda, who led the body design department until then.

The Classic used an air-cooled twin-rotor Wankel engine that had been developed by David Garside at BSA's Umberslade Hall research facility.The Wankel Rotary Engine: A History By John B. Hege page 137, "BSA, Born 1861, died 1973" - W P Murray, July 1994 - Staffordshire Garside, who had been impressed by the air-cooled single-rotor Fichtel & Sachs engine in the Hercules motorcycle, installed a bought-in F&S; engine into a BSA B25 'Starfire' frame as a "proof of concept". This proved reliable and smooth, but under-powered. Having obtained a licence from Felix Wankel in 1972, Garside then created a prototype twin-rotor engine (with F&S; rotors) which doubled the capacity of the earlier test "mule".

Attached to the clothing are two lightweight fans that help draw in air and help vaporize sweat. The fans, attached to the back of the clothing near the waist, are about 10 cm wide and run on rechargeable lithium ion batteries that last between 8.5 and 59 hours depending on the speed of the fan. One advantage of air-cooled clothing is that it requires much less energy to cool people down than to cool down their entire environment. For instance, an air cooled shirt uses 4,400 mAh of power for 8.5 hours on the fastest fan setting, while an average central air conditioning unit uses 3000 to 5000 watts of power.

The XF12C-1 This aircraft was initially powered by a Wright R-1510-92 engine but this was unsuitable so the aircraft was re-engined with a 775 hp (578 kW) Wright R-1670 fourteen cylinder, two row, air-cooled radial engine, which was also unsatisfactory. Both of these engines were prototypes and neither went into production. Finally, the 700 hp (522 kW) Wright R-1820-80 nine cylinder, single row, air-cooled radial engine was installed and the resulting aircraft, designated XF12C-1 flew in 1933. Designed for aircraft carrier usage, the parasol wing folded back, a new feature for the Navy, for storage and the aircraft had an exposed tail hook for carrier landings.

Kurogane also manufactured motorcycles, and keeping the engine as air-cooled helped with parts availability. The engine used for production was a Kurogane V1-AF motorcycle engine, with a bank angle of 45°, a V-type 2-cylinder OHV forced air-cooled engine with an engine displacement of 1.3 – 1.4 L developing @ 3,300rpm. It was a simple design, while the British made Sunbeam Motorcycle may have been used in reference to its development. The Japan Internal Combustion Engine Company was building three-wheeler trucks and motorcycles, using a single-cylinder engine of their "JAC” brand “Zaimasu" model motorcycle (zaimasu means “I will be there”) as the base engine used to develop the V2 engine.

The Honda CB550 is a standard motorcycle made by Honda from 1974 to 1978. It has a four-cylinder SOHC air-cooled wet sump engine. The first version, the CB550K, was a development of the earlier CB500, and like its predecessor, had four exhaust pipes, four silencers and wire-spoked wheels.

The plant was built with one air cooled condenser which compromises of 61 cooling modules of fins, tubes and fan arranged in four by four configuration, connected to the 132 kV electrical distribution system. The original output of the station was 325 MWe. The power station employs around forty-one staff.

This was later replaced by a 40 hp (30 kW) Rotax 447 air-cooled two-stroke engine for the initial B series of Shadows. Several different Rotax engines have been used in the subsequent C, D and E series and the Streak and Star Streak developments. Production began in 1984.

At the outbreak of World War I in August 1914, the Royal Aircraft Factory asked Rolls-Royce to develop a new air-cooled engine. Despite initial reluctance they agreed on condition that it be cooled by water rather than air, as this was the company's area of expertise.Pugh 2001, p.71.

Lawrance Aero Engine Company was an American aircraft engine manufacturer. Founded by engine pioneer Charles Lawrance, it designed one of the first successful air-cooled radial engines. It existed for only 5 years, being acquired by Wright Aeronautical, a much larger company better able to mass- produce Lawrance's radial engines.

The engine looks a bit like the VW air-cooled boxer four, except that the two cylinder banks are at a 90-degree angle. As Russian car owners were expected to do much of the servicing themselves, and auto workshops were in short supply anyway, this layout was more practical.

As of 2005 KenGen owned the Olkaria I (45 MW) and Olkaria II (70 MW) power plants. A third power station with 48 MW capacity, Olkaria III, is privately owned by a subsidiary of Ormat Technologies. The Olkaria III plant uses air-cooled converters, ensuring that there is no surface discharge.

With R.S. Moore, also a Scientist and Inventor, as his chief assistant, Berliner obtained automobile engines from the Adams Company in Dubuque Iowa, manufacturer of the Adams-Farwell automobile. This car used air cooled three or five cylinder rotary engines which were developed in-house by Fay Oliver Farwell (1859–1935).

It had tricycle gear with the main gear steel leaf sprung. The engine was a Volkswagen air-cooled engine with a wooden tractor propeller mounted in line with the wing and above the pilot, similar to a "Demoselle." The total construction cost was $600. Empty weight was and max weight was .

Changes included a larger cockpit and the powerplant was now a Continental O-200-A flat-four-cylinder air-cooled piston engine giving 75 kW (100 HP). In 1963 it was followed by the MFI-9B Trainer and then the MFI-9B Mili-Trainer. The MFI-9 uses a tricycle undercarriage.

Most Mk I bikes were brilliant red although a very small number were painted in metallic ice blue. An exceedingly small number of Series 2 bikes were white. In 1979, a small-block version of the air-cooled V-twin designed by engineer Lino Tonti was introduced as the V35.

The engine was derived from the air cooled, single-cylinder 4-stroke 125 Centomila unit. To gain the extra displacement, the bore was increased from 54 to 59.5 mm. The 125's stroke of 54 mm was retained. The cylinder was made of cast iron and the cylinder head light alloy.

The second and third aircraft were completed and sold in 1938. The final aircraft was completed in July 1939 and was powered by the new French-built 44 h.p. Train 4T four-cylinder inverted inline air-cooled engine. This aircraft (G-AFSV) was designated the D.W.1A, and the Hon.

This was largely built at Sociéte Anonyme Avions et Moteurs Renard. It was equipped with an air-cooled 240-hp Renard engine with a vertical axis. Like its predecessor, the Type II was equipped with two tandem rotors (one at the front and one at the rear) rotating in the same direction.

Between 1918 and 1939 aircraft technology developed very rapidly. In 1918 most aircraft were biplanes with wooden frames, canvas skins, wire rigging and air-cooled engines. Biplanes continued to be the mainstay of air forces around the world and were used extensively in conflicts such as the Spanish Civil War.Buckley (1999), p.

The engine was 4-cylinder air-cooled straight Cirrus III in front, 85 hp nominal power and 94 hp take-off power. Two-blade wooden propeller of a fixed pitch. A fuel tank behind a cockpit had a capacity 100 l and could be dropped in emergency. Fuel consumption was 26 l/hour.

Two air cooled V-10 gasoline engines, mounted toward the rear of the vehicle, were each connected to a generator to produce electricity. The generated electricity was then used to power the motors. Each engine produced 210 PS at 2500 RPM; a total of 420 PS was therefore available to drive the generators.

The air-cooled Gilmore, p.46. motor's built-in oil cooler, and the flat-four engine configuration's superior performance was also effective for the German Afrika Korps in Africa's desert heat. The suspension design used compact torsion bars instead of coil or leaf springs. The Beetle is nearly airtight and will briefly float.

Engines for vehicles are equipped with an air compressor, to supply compressed air for the brakes. It is an air-cooled single-cylinder air- compressor driven by a belt. The air-intake is next to the engine intake manifold. The crankcase is not divided, the crankshaft is forged and has two ball bearings.

Low pressure production uses a low temperature with a catalyst and hydrocarbon solvent. This process is less expensive and produces a polyethylene polymer more for textile use. The polymer is then melted, spun, by a spinneret into water, or air cooled. The fiber is drawn out to six times the spun length.

The Wooler Mule cyclecar was announced in February 1919. It was powered by a 1022 cc air-cooled twin with the cylinders protruding from the sides of the bonnet, and a circular dummy radiator. The engine used rotary valves. It had a double rear wheel giving the impression of a three-wheeler.

Only in January 1950 were the first 13 Granit 27 finished. In the next year the payload of the model was increased to 2 tons. 1952 the company presented the Phänomen-Granit 32 prototype that was equipped with an air- cooled diesel engine - in contrast to the carburetor engines used until then.

There were ailerons on both upper and lower wings. A pair of outward leaning, N-form cabane struts braced the upper wing centre section high over the fuselage. The usual wire bracing completed the wing structure. The trainer was powered by a neatly cowled, Renault 6Pei 6-cylinder inverted air-cooled inline engine.

The engine is a twin cylinder two-stroke, horizontally-opposed, air-cooled, , direct-drive, gasoline engine design. It employs capacitor discharge ignition and produces at 8500 rpm.

WDLA UK, Lancaster UK, 2011.

By 1932, Mitsubishi Heavy Industries was producing an air-cooled diesel engine that was suitable for tanks. It was placed experimentally into a Type 89. This later became known as the Type 89-B medium tank. Subsequently, Major Tomio Hara designed the suspension system, which was used on many future Japanese tanks.

The air-cooled engines should be a badge of Eicher Tractors later. In the following years, the product range was greatly expanded, with the models Eicher ED 30 (1949), Eicher ED 25 / I (1950) and Eicher ED 28 (1953). The name component ED stood for Eicher Diesel, also the production increased constantly.

Two different engines were used. The M35a had a 112 kW (150 hp), seven-cylinder radial Siemens Sh 14a, and the M.35b a 100 kW (135 hp) four-cylinder inline inverted air-cooled Argus As 8b. The former was the shorter and faster of the two. The aircraft first flew in 1933.

The Aerocar was an American automobile built from 1905 to 1908 in Detroit, Michigan. Backed by Henry Ford's former partner, coal merchant Alexander Malcomson, the short-lived company offered an air-cooled 24 hp (18 kW) four- cylinder luxury car which sold for $2800. The factory was sold to Hudson Motor Car Company.

Unlike the later de Havilland Gipsy Six the poppet valves were operated by a single gear driven overhead camshaft. The engine was first named the E97 and introduced to the market in 1932."Messrs. Napier Inaugurate a New Policy with a Six‐Cylinder Air‐Cooled Type", Aircraft Engineering and Aerospace Technology, Vol.

Warm air systems distribute heated air through duct work systems of supply and return air through metal or fiberglass ducts. Many systems use the same ducts to distribute air cooled by an evaporator coil for air conditioning. The air supply is normally filtered through air cleaners to remove dust and pollen particles.

Two most common engine types are an air-cooled engine or water cooled engine. Water cooled nowadays use antifreeze in the internal combustion engine Some engines (air or water) have an added oil cooler. Cooling is required to remove excessive heat, as overheating can cause engine failure, usually from wear, cracking or warping.

The airframe was effectively complete by June 1939, with only the engine awaited, with it being hoped that the aircraft would make its maiden flight by August 1939. This did not occur, however, and the aircraft did not fly until 25 July 1941, powered by a Régnier air-cooled inverted 12Hoo V12 engine.

Here, the exhaust steam is blown into an air-cooled radiator, similar to that used for the cooling system of an internal combustion engine. This system was used on small tram engines (where the condenser was mounted on the roof) and on large tender engines (where the condenser was mounted in the tender).

Aston Butterworth NB42 displayed at Motor Sport at the Palace Crystal Palace circuit, 25 May 2015 For 1952 Butterworth teamed up with Bill Aston to build the Aston Butterworth, an F2 car that competed in Grand Prix races, but was unreliable. Butterworth built the 1,986 c.c. air-cooled, flat-four-cylinder motors.

A third series of three heavier prototypes was built by Komatsu as SS4, with a more powerful engine, a new transmission and clutch and a two-speed auxiliary transmission.

The Caudron C.98 was a French sports/racing aircraft built by Caudron in the 1920s. Derived from the Caudron C.91, it was powered by a 230 hp Salmson 9 Ab 9-cyl air-cooled radial, and it was intended for the Coupe Zenith race.Hauet, André (2001). Les Avions Caudrons. 1.

Automobile engines may also use a heat riser, which heats the air/fuel mixture after it has left the carburetor; this is a low temperature fuel economy and driveability feature with most benefits seen at low rpms. Motorcycle engines may also use carburetor heating. In many cases, and especially with simple air-cooled engines, this relies solely upon an electric heating element attached to the carburetor, as a heat stove and attached warm air feed would be bulky, complex, difficult to route, and may even interfere with normal cooling of the cylinder block. On a few of their air cooled motorcycles, Ducati have utilized an oil line to warm the base of the carb which is operated by the rider via a small valve.

One of the primary differences between the N360 and the Honda Life that followed was the N360/600 had an air- cooled engine, and the Life had a water-cooled engine. The water-cooled engine was better able to comply with newly enacted emission standards in Japan, and reflected an industry wide move away from air-cooled as well as two-stroke engines. As does the original Mini, but unlike the succeeding Life, the N360/600 had its gearbox mounted in the sump rather than bolted on as a separate unit. An upgraded 36 PS (27 kW) engine was added in October 1968 for the N360 TS, which was sold as the N360 Touring following a minor update in January 1969.

The Beetle Challenge is a UK-based circuit racing championship for classic air-cooled Volkswagen Beetles. The general concept is to take any Beetle, of any age or model from the 40s through to 1303s, and with minimal restrictions, allowing parts from various years to be interchanged, and of course the cars being prepared to the MSA safety requirements (cage, restraints, fire system etc.) Essentially the cars must be air-cooled Beetles (any age and parts can be swapped between years and models), with a 15-inch x 6-inch max wheel size with a control tyre. Engines must be based on a Type 1 case, with no electronic fuel injection or ignition and no forced induction, with an unlimited capacity. Other regulations apply.

Before World War II had ended Jean Panhard foresaw that post-war demand for Panhard's typically large and expensive cars would be limited, and that a smaller less expensive model would be needed. Designer Louis Bionier began development of a small two-door front-wheel drive "voiture populaire" (people's car) that would be powered by a new air-cooled two-cylinder boxer engine designed by engineer Louis Delagarde. Automotive innovator Jean-Albert Grégoire was working on a similar project originally called the "Automobile Légère Grégoire" (ALG), later renamed "Aluminium Français Grégoire" (AFG) when the French national aluminum consortium stepped in to sponsor the project. Grégoire's design was also for a small, 2-door, front-wheel drive car powered by an air-cooled two- cylinder boxer engine.

This was the first time that cars bore the BMW brand on the roads. In 1928, Popp also concluded a license agreement with the US American company Pratt & Whitney, allowing BMW to manufacture two air-cooled radial engines. This ensured that BMW had access to key know-how in an area of aircraft engine construction with a great future. The expertise acquired through production under license allowed BMW to develop air-cooled radial engines under its own steam during the 1930s. Construction of the BMW aircraft engine factory in Allach (1935), expansion of the manufacturing facilities in Eisenach (1937) and acquisition of the Brandenburg Motor Works (Bramo) in Berlin-Spandau enabled BMW to expand capacities for aircraft engine manufacture under Popp’s leadership.

Darmont-Morgan from 1922 The Darmont-Morgan is virtually indistinguishable from the Morgan three-wheeler on which it was based. At the front was an air-cooled V-2 cylinder 4-stroke motor tilted forward and with a capacity of 1084 cc, which was enough to power the vehicle to a top speed of about 125 km/h (78 mph). By the time of the October 1928 Paris Motor Show the manufacturer was displaying a range of Morgan-based three wheelers, with a range of performance, levels, but most of them still with the 1084 cc engine of which both air-cooled and water-cooled variants were offered. The little cars had a successful career in street races and mountain races such as the Mont Ventoux Rally.

Air may be force fed with the use of a fan and shroud to achieve efficient cooling with high volumes of air or simply by natural air flow with well designed and angled fins. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through either a liquid cooling system nor through the metal fins of an air-cooled engine (12%). About 8% of the heat energy finds its way into the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. Air cooled engines usually run noisier, however it provides more simplicity which gives benefits when it comes to servicing and part replacement and is usually cheaper to be maintained.

Cross-section of a cylinder, along with the valves, spark plug, piston and connecting rod The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air- cooled engine, the walls of the cylinders are exposed to the airflow, to provide the primary method of cooling to the engine. Most air-cooled engines have cooling fins on the cylinders and each cylinder has a separate case in order to maximise the surface area available for cooling. For motorcycle engines, a "reverse cylinder engine" is where the intake ports are on the front side of each cylinder, and the exhaust ports are on the rear side of each cylinder.

Like the Volkswagen Beetle produced after the war, the first Volkswagen Transporters (bus) used the Volkswagen air-cooled engine, a 1.1 litre, DIN-rated 18 kW (24 PS, 24 bhp), air-cooled four-cylinder "boxer" engine mounted in the rear. The 22-kilowatt (29 PS; 29 bhp) version became standard in 1955, while an unusual early version of the engine which developed 25 kilowatts (34 PS; 34 bhp) debuted exclusively on the Volkswagen Type 2 (T1) in 1959. Any examples that retain that early engine today are true survivors – since the 1959 engine was totally discontinued at the outset, no parts were ever made available. The second- generation Transporter, the Volkswagen Type 2 (T2) employed a slightly larger version of the engine with 1.6 litres and .

At this time, other companies, known as plug compatible manufacturers (PCMs), were competing with IBM by producing IBM- compatible systems. By the late 1970s and early 1980s, patented technology allowed Amdahl IBM-compatible mainframes of this era to be completely air- cooled, unlike IBM systems that required chilled water and its supporting infrastructure— the 8 largest of the 18 models of the ES/9000 systems introduced in 1990 were water-cooled; the other ten were air-cooled. "The 3033 model, introduced in response to competition from the Amdahl Corporation, represented almost a 100 percent improvement in performance over the previous model, at only a 12 percent increase in price". The improvement in Price–performance of the 303X models created volume of orders sufficient to cause a backlog.

The weapon is described as an "air-cooled, electrically powered, rapid firing weapon."United States, 1969. p. F-4 All portions of the firing cycle are powered this way so the unit requires an external power source. Other important features are the reciprocating barrel and cam assembly that drive the other components of the system.

30 caliber air-cooled machine guns resembling the M1919 Browning machine gun. It is also stated that the USA and CSA are equipped with similar .50 caliber pieces that in our timeline can only be the Browning M2. This is odd in that this timeline's John Browning was a Mormon born in Ogden, Utah.

Lanchester designed a new 8 hp (6 kW) 2,895 cc (177 in3) air-cooled engine with two horizontally opposed cylinders, still with two crankshafts. He also re-designed the epicyclic gearbox and combined it with the engine. A driveshaft connected the gearbox to a live axle. The new engine and transmission were fitted to the original 1895 car.

This rebodied "-033" was named "-033.S". The car was powered by a water-cooled 1186 cc 4-cylinder boxer Alfa Romeo engine replacing the older air-cooled Volkswagen engine. With its higher power output it gave the car more brilliant performances . The second series remained in production until 1991 when the third series was launched.

Around it were the six flame cans. The turbine was made of solid Inconel blades attached to an austenitic steel hub. The blades were air cooled by bleeding off compressed air from the fifth compressor stage and piping it to the turbine face, the six pipes lying between the flame cans. The exhaust section consisted of welded steel sheeting.

The engine is the "Desmodue", a 90° L-twin, air-cooled engine with desmodromic valve actuation. A slipper clutch prevents locking of the rear wheel through clumsy down-shifting. Although Ducatis often use a dry clutch, this model has a 21-plate oil-bath "wet clutch" which weighs less, gives quieter operation, and needs less maintenance.

The Ailloud was a French automobile, built between 1898 and 1904 by Claude Ailloud of Lyon. The first car had a 618 cc twin-cylinder air-cooled engine, rear-mounted, driving through a 3-speed gearbox and chain drive. To improve cooling the engine was soon moved to the front of the car. Probably only one was made.

These models used air-cooled or liquid-cooled variations of motorcycle engines. The engine was placed ahead of the axis of the front wheels in a chassis made of steel tubes brazed into cast lugs. After the First World War, the company introduced an easily changed rear wheel, which customers had been seeking for several years.Boddy, p.1412.

The Type 96 25mm Gun is a simple air- cooled gas operated design. The barrel is a forging screwed into the breech mechanism.

Accessed 2015-05-31 It had an air-cooled, transverse-mounted inline four-cylinder engine with two valves per cylinder operated by a single chain-driven overhead camshaft. Fuelling was provided by four 20 mm Keihin carburettors. The CB400F is commonly known as the Honda 400 Four.

The platform allowed 360 degrees of rotation for both the gunner and the gun. A Type 100 air-cooled inline six-cylinder diesel engine was used to output 130 horsepower. Forward transmission included four stages, with one reverse speed. Type 98 Ke-Ni chassis and engine, on which the prototype was based managed a speed 42 km/h.

The two prototypes built, had steel tubing fuselages, covered with metal and fabric and v-tails with tail rotors at their tips. The plywood covered main rotors had three blades with steel tubing spars. The helicopter had a six-cylinder air-cooled Lycoming VO-435-A1B engine, producing 260 hp. The fuel tank was capable of holding 180L.

The initial 250 model was propelled by a 247 cc air-cooled, single- cylinder OHV engine. Bore and stroke was 69 x 66 mm and compression ratio was 7.2:1. Breathing through a 24 mm Dell'Orto carburettor, the engine produced 14 bhp (10.4 kW) at 5,600 rpm. A geared primary drive fed the power to a 4 speed gearbox.

The car was powered by an air-cooled, horizontally opposed six-cylinder engine constructed with many major components made from aluminum. The engine was mounted in the rear of the car, driving the rear wheels through a compact transaxle. Suspension was independent at all four wheels. No conventional chassis was used, being the first unibody built by Fisher Body.

The most common electrode holder is a semiautomatic air-cooled holder. Compressed air circulates through it to maintain moderate temperatures. It is used with lower current levels for welding lap or butt joints. The second most common type of electrode holder is semiautomatic water-cooled, where the only difference is that water takes the place of air.

The departure block, waiting area and food court are air cooled. Reverse Osmosis plants have been installed to supply clean drinking water to the passengers. A new parking management system has also been developed which is capable of storing data of buses entering and exiting the premises. The bus stand has a slew of hotels, restaurants at hand's reach.

The SIGM400 is a family of firearms manufactured by SIG Sauer. The M400 is an air-cooled, direct impingement gas-operated, magazine-fed carbine that is based on the earlier AR-15 rifle. Depending on the variant, it can be chambered for 5.56×45mm NATO or .300 AAC Blackout cartridges, and may have a fixed or telescoping stock.

The materials were also selected because they could be obtained at a typical hardware store of the day. Power is derived from the ubiquitous air- cooled Volkswagen automobile engine with modifications laid out by the designer in the plans. The fuselage is a monocoque design. The empennage consists of a single vertical tail with a hinged rudder.

70 kg class UAV is an unmanned helicopter developed by Blue Sky by integrating COTS airframe with flight control system indigenously developed by Blue Sky. 70 kg class UAV adopts liquid-cooled engine instead of air-cooled engine adopted in most Chinese UAVs, and it is in conventional helicopter layout with a pair of skids as landing gear system.

Track width was to be 35 cm. The normal wading capacity was to be 145 cm; BDR thought it also possible to make the tank fully immersible to cross rivers while being guided from the river bank.Stéphane Ferrard, 2007b, p. 66 It was planned to install an air-cooled Potez 12V 320 hp engine, placed transversely in the hull.

Power was provided by a rear-mounted 540 cc OHV air- cooled two-cylinder four-stroke engine. It was the first car in Japan with a horizontally opposed engine. The car was adapted from one of Daihatsu's three- wheeled delivery trucks. It sold very poorly, production was highly labor- intensive and ceased after only approximately 300 units were built.

Originally, and for many years, engines were required to be 4 cylinder VW air or water cooled engines, other main manufacturer of these was Porsche, a company closely tied to Volkswagen through shared design and heritage. By the mid 2010s these large displacement air-cooled VW-type engines had become difficult and expensive to acquire and maintain, and a number of racers active in the class began the process of working to enlarge the list of available engines to keep the class alive and reduce costs for those competing it. As a result of these discussions and negotiations a decision was made to allow any production based 4 cylinder engine of 2500cc or less to be used in the class. The rules still permit the use of unlimited displacement VW air- cooled type engines.

Before the end of World War II venerable French automaker Panhard et Levassor foresaw that post-war demand for their typically large and expensive cars would be limited and that a smaller less expensive model would be needed. Designer Louis Bionier began development of a small two-box "voiture populaire" (people's car) that would be powered by engineer Louis Delagarde's new air- cooled two-cylinder boxer engine driving the front wheels. At the same time automotive innovator Jean-Albert Grégoire was working on a car originally called the "Automobile Légère Grégoire" (ALG) later renamed "Aluminium Français Grégoire" (AFG) when the French national aluminum consortium stepped in to sponsor the project. The resulting prototype was also a small front- wheel drive car powered by an air-cooled two-cylinder boxer engine.

By 1932 Walter production had slumped to 217 cars for the year. The figure recovered to 474 in 1933, but fell again to 102 in 1936 and to only 13 in 1937. Walter ceased car production in 1954. Walter Standard 6 From the early 1920s Walter also manufactured BMW aircraft engines under license, as well as its own family of air-cooled radial piston engines. In the 1930s Walter also made Bristol Jupiter, Mercury and Pegasus engines under licence, and then created its own in-line inverted air-cooled four- and six- cylinder engines, and in 1936 an air-cooled inverted V12. Walter aircraft engines were used by the air forces of 13 countries before World War II. During World War II Walter made Argus engines under license for Germany. Manufacture of the BMW 003 turbojet was put into preparation, but none were produced. The Walter plant survived the war intact and in 1946 the company was nationalized as Motorlet n.p. It made Soviet-licensed piston engines, and in 1952 began manufacturing the Walter M-05 jet engine. This was the Soviet Klimov VK-1 engine, based on the Rolls-Royce Nene, which powered the MiG-15, and was exported to many countries.

The M249 is gas operated and air-cooled. It has a quick-change barrel, allowing the gunner to rapidly replace an overheated or jammed barrel. A folding bipod is attached near the front of the gun, though an M192 LGM tripod is available. It can be fed from both linked ammunition and STANAG magazines, like those used in the M16 and M4.

The Kawasaki Z750 twin is a twin-cylinder, touring motorcycle announced in 1975 and manufactured from 1976 to 1978. It was based on the smaller Kawasaki KZ400 introduced in 1975. The air cooled engine shared similar engine design with the KZ400 having chain-driven twin dynamic balancer shafts. The valve seats were hardened to allow use of low-grade fuel.

Liquid-ring vacuum pumps can use any liquid compatible with the process, provided it has the appropriate vapor pressure properties, as the sealant liquid. Although the most common sealant is water, almost any liquid can be used. The second most common is oil. Since oil has a very low vapor pressure, oil-sealed liquid-ring vacuum pumps are typically air-cooled.

The standard engine used is the Russian Vedeneyev M14P nine cylinder, air-cooled, four stroke radial engine. The Culp Special has a typical empty weight of and a gross weight of , giving a useful load of . With full fuel of the payload for pilot, passengers, and baggage is . The manufacturer estimates the construction time from the supplied kit as 2500 hours.

The original model was equipped with a air-cooled, four- stroke, 8V (8 valve), OHC engine with both electric self-start and kick start. This version has a fuel tank, of which one litre is reserve. In 2012, HMSI launched a new Dio at Auto Expo in India. It has a new engine, which also runs Honda's Activa and Aviator.

The Autogear was a three-wheeler car built in Leeds, Yorkshire between 1922 and 1923. The Autogear was different from most other three-wheelers in having only one wheel at the front and two wheels at the rear. The air-cooled 10 hp V-twin engine drove the front wheel, which also steered. The Autogear weight 7.75 cwt and cost 185 pounds.

Construction apart, the Cairns A was a conventional cantilever low wing monoplane. The wings, trapezoidal in plan with only slight taper out to blunted tips, carried short ailerons. The first example flew in April 1930 and was powered by a Cairns G, a licence-built, four cylinder, Gipsy I air-cooled upright inline engine. Its engine determined its AG-4 sub- type designation.

The German air force carried out the first terror bombing raids, using Zeppelins to drop bombs on Britain. By the end of the war airplanes had become specialised into bombers, fighters, and surveillance aircraft. Most of these airplanes were biplanes with wooden frames, canvas skins, wire rigging and air-cooled engines. Between 1918 and 1939, aircraft technology developed very rapidly.

Each connecting rod big end had roller bearings. In 1979 it was replaced by Honda CD185. From 1967 to 1968: the machine had a 4 stroke 360 degree parallel twin; air cooled; single overhead cam (chain driven); cylinders inclined 30 degrees forward from vertical ("sloper" engine) with 9:1 compression ratio; max 17 bhp @ 10,500 rpm.Motor Cycle 3 August 1967 pp.

It featured a rear-mounted air-cooled, twin-cylinder engine mounted under the floor driving the rear wheels through a three-speed motorcycle-type gearbox. The steel channel section chassis had all-round independent suspension with swing axles at the rear. Most cars had two seater estate car bodies, but some four-seat saloons were also made. The bodies were made of aluminium.

Bluefire relies on a water-based cooling system that is 33 percent more energy efficient than traditional air- cooled systems. Heat is removed from the electronics by water-chilled copper plates mounted in direct contact with each POWER6 microprocessor chip. As a result of this water-cooled system and POWER6 efficiencies, Bluefire is three times more energy efficient per rack than its predecessor.

The Wright XR-1510-12 engine in the XSBC-2 proved to be mechanically unreliable. In March 1936, this aircraft was re-engined with a 700 hp (522 kW) Pratt & Whitney R-1535-82 fourteen-cylinder, twin-row, air-cooled engine driving a three-blade propeller and redesignated XSBC-3. With this new configuration, the Navy placed a production order.

The A-3 was originally powered by a M-11 five-cylinder air-cooled radial engine. On later models this was replaced by a AI-14R radial mounted on a shock-absorbing tubular frame. A removable cowling covers the oil tank and pipes for the lubrication system. The twin fuel tanks are concealed within the hull on either side of the cabin.

He supplied one of his engines to Enrico Forlanini and developed it further into a three-cylinder, air-cooled, radial engine ideal for the new aeroplanes. One of the early engines, the 25 hp Anzani W-3 or Fan type, was supplied to Louis Blériot who used it on his successful first aircraft crossing of the English Channel in 1909.

The bodywork was minimal. The 165 cc, air- cooled, flat twin two-stroke engine drove the right-hand rear wheel by chain, and a variable-speed friction drive transmission was used, giving two forwards speeds and reverse. A top speed of 30 mph was claimed. A motorcycle using the same engine, also with friction drive, was also offered for £28 10 shillings.

A two-cylinder engine was fitted to the same chassis in 1897 and a second complete car was built alongside it. This led on to the first production cars in 1900, when six were made as demonstrators. These had two-cylinder, 4033 cc, horizontal air- cooled engines, retaining the twin crankshaft design. Steering was by side lever (or tiller) not wheel.

By 1969, the new Minica Van had superseded the LT23 and it was no longer produced, although the LT25 pickup continued to be built until 1971 (at least). These late models have the air-cooled ME24E engine with , although top speed remained . It also has the same blacked-out plastic grille as fitted to the Super Deluxe and late first- generation Minicas.

MOL is a manufacturer of specialist trucks and trailers, based in Hooglede, Belgium. It was founded in 1944. In the 1970s, MOL made a variety of oilfield trucks with air-cooled Magirus Deutz engines. MOL bought the rights to Willème truck designs, and some MOL ballast tractors continued to be based on these trucks for some years, after Willème went bankrupt.

The Vee Gee was an early British cyclecar made in 1913 only. It got its name from its maker Vernon Gash who was based in Leeds, Yorkshire. The car seems to have been better engineered than most cyclecars with a tubular metal frame. The 8 hp V-twin JAP engine was air-cooled and had a conventional 3-speed transmission.

In June 1902, the company was already producing Brennan Standard Motors which ran from 4 to 30 horsepower. According to advertisements, they were the "recognized type of motor for automobiles." Both water-cooled and air-cooled engines as well as mufflers and vaporizers were manufactured at the company's plant. They also offered a special 8 horsepower motor with a transmission gear.

The "Pure Enduro" series of off-road racing motorcycles ran from 1977 through to 1984 in engine displacements from 175cc through 400cc. All engines were case-reed valve, air-cooled, two-stroke and single-cylinder with plain steel bores. Lubrication was provided via 20:1 pre-mix. These were directly related to the Suzuki RM series (Racing Model) range of motocross racers.

Other features were 40 mm Forcella front forks, Veglia instruments, and a steel petrol tank. This was the same year the liquid-cooled Desmoquattro engine appeared on a racer at 1986 24H of Montjuic. While air-cooled models are still produced, development since has focussed more on the liquid-cooled models. The 750 F1 continued to be produced in 1987 and 1988.

The MK2A Zuisei engine was a 14-cylinder, supercharged, air- cooled two-row radial engine with a 140 mm (5.5 in) bore and 130 mm (5.12 in) stroke for a displacement of 28L (1,710ci) and a nominal power rating of 805 kW (1080 hp) for takeoff and 787 kW (1055 hp) at 2800 meters (9185 feet).Francillon p 376 Mitsubishi used the standard designation system to identify this engine while it was under development. The MK2 designation starts with the Manufacturer's assigned identification letter, in this case, "M" for Mitsubishi, followed by a letter that identifies the engine arrangement, in this case "K" for air-cooled, and then the sequentially assigned design number, in this case "2" for the second design. Revisions to the engine are identified by the letter following the preceding designation, with letter "A" being the original, or first, version.

It also used an aluminium construction for both the block and head (which was rare for the time). Lancia produced V4 engines until 1976, when they were replaced by flat-four engines. The 1960-1994 ZAZ Zaporozhets was a Ukrainian city car which used a rear-mounted V4 engine. This engine— based on the engine used in the LuAZ-967 amphibious militiary vehicle— was air-cooled with a magnesium block and was produced in displacements from . The AMC Air-cooled 108 was a built from 1960-1963 for use in the lightweight M422 Mighty Mite military vehicle. The M422 was by Jeep in the United States and designed to be transported by helicopter. Beginning in the 1960s, Ford's European divisions produced two unrelated V4 engines. The first was the Ford Taunus V4 engine, produced in Germany from 1962–1981.

The inlet manifold and parts of the carburetor often have warm water from the cooling system or exhaust gas circulating through them to combat this problem. Motorcycles can also suffer from carburetor icing, although some engine designs are more susceptible to it than others. Air-cooled engines may be more prone to icing, due to the absence of warm coolant circulating through the engine.

The only difference between the two was the type of engines used. The XC-123 used two Pratt & Whitney R-2800-23 air-cooled radial piston engines, while the XC-123A was fitted with four General Electric J47-GE-11 turbojets, in two pods.Andrade 1979, p. 87. The XC-123A also has the distinction, while only experimental, of being the USAF first jet-powered military transport.

The Cabin is powered by an air-cooled single-cylinder 2-stroke Gasuden engine, producing and giving the car a top speed of . Despite being one of the most successful cars of its type in Japan's post-Second World War automobile market, only 85 units were built, partly because of the relatively poor quality of its fibreglass body and partly because of its relatively high price.

The American Tri-Car was made by the Tri-Car Co of America, Denver, Colorado, United States, in 1912. It was a three-wheeler, with the one rear wheel being both the drive wheel and the only braked wheel. It was powered by a 13 hp, air-cooled 2-cylinder engine and used a planetary transmission. It seated two and had a wheelbase of .

The NH series of Honda scooters was sold worldwide beginning in 1983, in 50, 80, 90, 100 and 125cc versions. All models have an air-cooled two-stroke engine with CDI ignition. All models except the Lead 50 have leading link front suspension, electric and kick start, and a fuel gauge. The Lead 50 has a traditional telescopic fork front suspension and only electric start.

The Typ 87 is powered by an air-cooled flat-four-cylinder-otto engine with a displacement of 1131 cm3 and a rated power of . Vehicles made for the German Africa Corps were often equipped with the tropic equipment. The tropic equipment protects the air filter, the carburettor and the electrics from dust. In addition to that, sand tyres are also a part of the tropic equipment.

The Yamaha TT600R is an enduro motorcycle from Yamaha Motor Company closely related to the XT series of air-cooled single cylinder engines. The TT600R model was released in 1998 to 2002, where it was replaced in 2003 by the TT600RE that was available from 2003 to 2007. It is no longer offered in its present form. The TT600R's engine was basically a XT600 3TB engine.

Wise, p.506. It had a peculiar structure, it featured independent suspension by transverse spring and two single-cylinder air-cooled engines produced by De Dion-Bouton sharing a common crankcase. The engine, allegedly producing , was mounted under the seat and drove the back axle through an unlubricated two- speed transmission. It had an advanced sliding-pillar front suspension, but no suspension at all in the rear.

The Armstrong was a British 4-wheeled cyclecar made in 1913 and 1914 by the Armstrong Motor Company of Birmingham. The car was available with a choice of air- or water-cooled, two-cylinder 8 hp engines made by Precision. The cheaper air-cooled version had belt drive to the rear axle, but the dearer water- cooled model had shaft drive. The number made is not known.

45 was powered by a 115 hp (86 kW) Cirrus-Hermes IIB four cylinder inverted air-cooled inline, which drove a two blade propeller. Its undercarriage was of the fixed, conventional type, with the mainwheels on axles forming an inverted V and attached to the central fuselage underside. The main legs, with shock absorbers, were mounted on the upper longerons. There was a small tailwheel.

2 four cylinder inverted inline air-cooled piston engine, but there was a wide range of suitable engines, both inline and flat fours, in the power range 44-63 kW (59-85 hp). The second prototype, for example, had a 48 kW (65 hp) Continental A 65 flat four. Though the inline Régnier engine was fully cowled, some of the flat fours have had exposed cylinder heads.

Two more were built as the Do E II, with Gnome-Rhone Jupiter air-cooled engines. The Do E I was distinguished from the Wal and the Do E II by having a wing covered with metal panels, instead of fabric. Dornier registered the two Do E II aircraft for the 1926 German contest for seaplanes, but cancelled their participation shortly before the start.

The IO-580 family of engines covers a range from . The engine has a fuel injection system which meters fuel in proportion to the induction airflow through air-bled nozzles at the individual cylinder intake ports. The engine has a displacement of and produces a maximum of in its B1A version. The cylinders have air-cooled heads cast from aluminum-alloy with a fully machined combustion chamber.

Built using a shoulder wing configuration, giving the pilot unrestricted forward visibility, the Ar 198 was of steel tube construction for the forward fuselage structure with all- metal monocoque construction of the tailboom. An air-cooled radial BMW 132 engine was initially chosen, but due to availability concerns, the first prototype was fitted with the slightly lower-powered Bramo 323 A-1 of the Brandenburgische Motorenwerke.

There are two main versions of the boxer 4-stroke engines. Those with the casing of air-cooled beetle engines, and those with the largely similar, but stronger Wasserboxer casing used in late VW vans before the Volkswagen Transporter (T4). Even though the Wasserboxer engine is water- cooled, this involves only the cylinders and the top. The casing has no water lines, it is only stronger built.

A portable air conditioner can be easily transported inside a home or office. They are currently available with capacities of about and with or without electric-resistance heaters. Portable air conditioners are either evaporative or refrigerative. The compressor-based refrigerant systems are air-cooled, meaning they use air to exchange heat, in the same way as a car radiator or typical household air conditioner does.

Volkswagen had only just started small scale production, building about 210 Beetles, when civilian production was halted at the start of the war. Except for two military prototype units, these KdF sedans were allocated to military officers as personal cars. Hitler was given the very first convertible Beetle built in 1938. Both 704cc and 984cc air-cooled engines were fitted in these early units.

The Beetle outlasted most other cars which had adopted the rear- engine, air-cooled layout such as those by Subaru, Fiat, and General Motors. Porsche's 356 series which originally used some Volkswagen-sourced parts, continued to use the classic rear-engine layout (which later became water cooled) in the Porsche 911 996 series, which remains competitive in the third decade of the 21st century.

The final stage of each transmitter contained three parallel 3J/261E air cooled triodes running in class C at 90% efficiency. These were driven by a class B modulator with the same type of valves. The outputs of the two transmitters were fed by separate transmission lines to the coupling hut at the base of the guyed mast antenna, which accepted and radiated both signals.

The undercarriage was just a single wheel mounted partly inside the fuselage. The unique feature of the Auxiliary was the powerplant and its mounting. Carden had selected a 250 cc single-cylinder, air-cooled two-stroke Villiers motorcycle engine. He encouraged Villiers to persuade this engine to run inverted, in order to put the propeller line to the top of the mounting and thus minimise air resistance.

As well as producing aircraft and building Hispano- Suiza and Lorraine aero-engines under licence, Avia also designed and built their own radial engines. Their Rk.12 was a seven-cylinder supercharged model, rated at 200 hp. It was a conventional air-cooled radial: nitrided steel barrels with integral fins were screwed into heat-treated Y alloy heads. The pistons were also of heat-treated Y alloy.

They must also be heated hot enough for all of the alloys to be in solution; after forming, the material must be quickly cooled to .Degarmo, pp. 116–117. Cold-worked microalloyed steels do not require as much cold working to achieve the same strength as other carbon steel; this also leads to greater ductility. Hot-worked microalloyed steels can be used from the air-cooled state.

The Bergspyder is powered by the air-cooled 2-liter eight-cylinder boxer engine used in the type 771. This engine had its first use in 1962 in the Porsche 718 RS 61 [21] and already had a Bosch injection system for mixture preparation. The valves were operated by two overhead camshafts with vertical shaft drive.Jürgen Barth, Gustav Büsing: Das große Buch der Porsche-Typen. Rennwagen.

Salmson 9Ad, 46 hp (40 hp nominal power), 9-cylinder air-cooled radial engine in front, driving a two- bladed metal propeller (wooden in the prototype). Conventional fixed landing gear, sprung by rubber rope, with a rear skid.

The trike carriage is of composite materials and is an aerodynamically faired design. Its span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a single-cylinder, air-cooled, two-stroke Polini Thor 100, Polini Thor 200 engine or the Bailey 200 V4. The aircraft has a carriage weight of and an empty weight of .

The project application indicated that the power plant would be fueled with natural gas and that it would be air-cooled. The capital cost of the project would be $530 million. According to the project's proponents, the plant would have generated enough electricity to supply 450,000 homes and businesses annually. The California Energy Commission gave its final approval to the project on December 16, 2009.

A Mitsubishi Leo, photographed at Fukuyama Motor and Clock Museum. The 1959 Mitsubishi Leo, heavily influenced by the Mizushima, was a transition between the company's first post-war vehicles and the Mitsubishi Minica, which represented the company's future in the 1960s. The Leo used a 309 cc air-cooled single-cylinder engine, the ME20, producing 12.5 hp at 4,500 rpm. Payload was , top speed .

Vapor compression chillers may be bundled with an air- cooled condenser to provide a packaged chiller, which would be installed outside of the building envelope. Vapor compression chillers may also be designed to be installed separate from the condensing unit; normally such a chiller would be installed in an enclosed central plant space. Absorption chillers are designed to be installed separate from the condensing unit.

The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of . The aircraft has a standard empty weight of . It features a single main rotor, an enclosed cockpit with a windshield, skid-type landing gear and a twin cylinder, air-cooled, two- stroke, single-ignition Hirth 2703 engine. The aircraft fuselage fairing is made from composites.

The span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a V twin-cylinder, air-cooled, four-stroke Briggs & Stratton Vanguard engine. The landing gear has an adjustable track width, depending on the application and wing used. The aircraft has an empty weight of and carries a full fuel load of .

They also became liquid-cooled and had an 'LC' appended to the name to designate this e.g.: RD350LC - some people referred to them as the "Elsie". The Elsie is the link between the earlier air-cooled RDs, and the later power valve (YPVS) equipped RZ series. The most common capacities sold in Australia were 250 cc (maximum capacity allowed for new road riders) and 350 cc.

With the increasing arms production in Nazi Germany the product portfolio was reduced to the Granit 1500 model (called Granit 27 after the war) with a payload of 1.5 tons. All Phänomen trucks and tricycles had air- cooled engines, only the four-wheeled passenger cars were equipped with water- cooled engines. In 1930, the company took up production of light motorcycles, using Sachs engines.

Most vehicles were equipped with a petrol engine. The type designation LO (Luftgekühlter Ottomotor, German for air-cooled petrol engine) led to the nickname Ello which became the popular designation for all Robur trucks, as it is impossible to differentiate between the diesel and petrol engines from the outside. The vehicles were modified for a number of different purposes, e.g. a mobile pharmacy, fire engines and dumpers.

The aircraft has a welded steel tube fuselage and rudder with a wooden and fabric covered wing, tailplane and elevator. It weighs 165 kg without an engine. Early aircraft were equipped with a 40 hp Stamo Volkswagen air-cooled engine with later types using either 40 hp Pollman-Hepu or 45 hp Stark Stamo engines. More recently the Jabiru 2200 engine has been used.

The design allows for the complete electric power demand to be supplied with only one generator. Emergency Caterpillar 3306 harbor generator located at main deck aft provides 105 ekW in case of main generator failure. The emergency set is air cooled and configured for automatic startup on loss of the ships main power. Main engine room is protected with a carbon dioxide extinguishing system.

Its span wing uses an "A" frame weight-shift control bar. The powerplant is a twin cylinder, air-cooled, two-stroke, single-ignition Rotax 447 engine or the twin-cylinder, in-line, two-stroke Kawasaki 340. With the Kawasaki 340 engine the aircraft has an empty weight of and a gross weight of , giving a useful load of . With full fuel of the payload is .

Disc brake cars use green LHM fluid – a mineral oil – which is not compatible with standard glycol brake fluid. The disc brakes were forced-air cooled by ducts drawing air from the engine fan housing, greatly reducing the likelihood of the brakes to overheat or fade in heavy use - especially during long descents in hot summer conditions in the Alps and other mountain regions.

30 caliber Browning M1919A4 or 7.62mm M60 machine gun. The 500 hp, six-cylinder, Continental (or Lycoming Engines), air-cooled, gasoline engine is located in the rear of the vehicle. It was driven by a cross-drive, two-speed Allison transmission. Although the M42 Duster was initially designed for an anti-aircraft role, it proved to be highly effective against unarmored ground forces in the Vietnam war.

The acceptable power range is and the standard powerplant is the Volkswagen air-cooled engine. For aerobatics the BA 100 is stressed to +/-9g The BA 100 Aerobat has a typical empty weight of and a gross weight of , giving a useful load of . With full fuel of the payload for pilot and baggage is . Factory kit options included conventional landing gear and a STOL kit.

The F-30 is equipped with a dual capacitor discharge ignition system and is free-air-cooled, with optional fan cooling. The cylinder walls are electrochemically coated with Nikasil. Standard starting is electric start and recoil start is not an option. The reduction drive system available is the G-40 gearbox with optional reduction ratios of 2.03:1, 2.25:1, 2.64:1, 2.96:1 and 3.33:1.

The Vortech Shadow was designed to comply with the US Experimental - Amateur-built aircraft rules. It features a single main rotor, a two-seats-in side-by-side configuration enclosed cockpit with a windshield, tricycle landing gear, plus a tail caster. The acceptable power range is . The standard engine used is the four cylinder, air-cooled, four-stroke, dual-ignition Lycoming O-320 powerplant in pusher configuration.

In 1950 Cole was asked to oversee production of the M41 Walker Bulldog tank at Cadillac's Cleveland facility. The M41 was powered by a Continental AOS-895-3 engine. This was a six-cylinder, air-cooled, four-stroke supercharged boxer engine that displaced . Cole also logged over 300 hours piloting a Beechcraft Bonanza powered by a smaller Continental engine with the same basic layout.

A new chain driven M.50 Four was released with a new Amac carburettor and front brakes. In 1931 a Villiers 198 cc two-stroke FN model appeared. In 1938, the M.12 992 cc air- cooled sv flat twin was built for military use, and the all alloy M.11 was released in 350 cc ohv, 500 cc sv and 600 cc sv models.

The Gannet was Gloster's intended entry. It was a small, single-bay biplane, one of the smallest aircraft built in Britain. It was powered by a specially designed Carden vertical two- cylinder air-cooled two-stroke engine of exactly 750 cc.Flight 4 October 1923 The thick wings were based on a pair of spruce I-section spars with spruce ribs and internal wire bracing.

The Honda Nighthawk 250 is a Honda standard motorcycle. It has a air-cooled parallel-twin engine. While the first Nighthawk (CB650) was manufactured in 1982, the first 250 Nighthawk was manufactured in 1991. It utilized the 1985–87 CMX250 Rebel engine with all new wiring and components and reshaped the Rebel cylinder head slightly as well as incorporating a larger carburetor and new valve cover.

As a general description, the ST-series bikes have a bench-style saddle, small fat tires, and folding handle bars. They have an air-cooled 4-stroke engine with either a semi-automatic 3-speed transmission, with an automatic centrifugal clutch, or a 4-speed manual gearbox. The ST90 uses larger 3.00-14 tires, compared to the 3.50-10 and 4.00-10 of the smaller bikes.

The S-9 was a three-seat mid-wing monoplane with constant-chord wire-braced wings originally powered by a Gnome air-cooled rotary engine rated at . It was the first monocoque monoplane built in Russia and the cylindrical tapered fuselage was constructed of plywood 5 mm thick in the forward section and 3mm thick aft. Construction was completed in the spring of 1913.

Due to the weight of the engine, the aircraft needed a long takeoff run and had a poor rate of climb. The prototype was rebuilt as the Wicko F.W.2 with a more powerful but much lighter – 227 lb (103 kg) – air-cooled Cirrus Minor I engine. This resulted in a useful reduction in overall weight but the price increased from £425 to £650.

He persuaded Halford to undertake its design and development. The cylinders, pistons, con- rods and gearing were taken from the Renault, with the valve gear based on the Airdisco, and a new five-bearing crankshaft and cast crankcase were designed.Taylor 1999, pp.74-5. It became the first Cirrus engine, and the first air-cooled four-cylinder inline aero engine to go into quantity production.

The prototype was finished in the American national racing colours of white with a blue stripe. It featured two bucket seats and a three-cylinder air-cooled Excelsior engine mounted transversely in the frame with final drive by roller chain. Unlike all other Friskys, the rear axle was full width and fitted with a differential. The car was also independently sprung using a swing axle layout.

When production of the Kestrel engine ceased, a new variant of the Master was designed that used an air- cooled Bristol Mercury XX radial engine, capable of producing 870 hp (650 kW), instead."The Mercurial Master." Flight, 26 June 1941. p. 434. Thus configured, on 30 October 1939, the first M.19 Master II prototype made its first flight; 1,748 aircraft were eventually built.

Powered by a 10-horsepower, two-cylinder, air-cooled gas engine, this open car with seating for approximatively six people was most probably acquired in 1906.Johnson, Eric L. The Bonanza Narrow Gauge Railway. Rusty Spike Publishing, 1997, pp. 85. The remains of the motor car, wheel-less since 1944, now sit in the Dawson City Museum locomotive shelter aside KMRy #1 to #3.

DWM introduced the Pistol Parabellum ('Luger Pistol') in the early 1900s. It was worked on by Georg Luger and Hugo Borchardt. DWM manufactured the Maschinengewehr 01 and Maschinengewehr 08, licensed version/clone of the Maxim machine gun. The MG08 would be the main German machine gun of the First World War, alongside the somewhat different, air cooled Parabellum MG 14/17 for aviation use.

Work on the design of the VP-1, was completed between 1966 and 1968, the intention being that the design would be simple to build for a novice working at home. The design was successful, and, following a first flight in September 1968, a large number of aircraft have been constructed by homebuilders. The aircraft are usually powered by converted Volkswagen air- cooled engines.Mooney, Walt.

Crew of two was sitting in tandem in the fuselage. The cockpits were open in upper part on the sides, with individual doors on the right side. 5-cylinder air-cooled 88 hp radial engine Armstrong Siddeley Genet (80 hp nominal power, 88 hp take-off power) was mounted in front and drove two-blade wooden propeller. Conventional fixed landing gear, with a rear skid.

The Apache is controlled with a conventional weight shift "A" frame control bar. Standard features include a fiberglass cockpit fairing, wheel pants, nosewheel brakes and stowage bags. Dual control steering and throttle are optional for flight training use. The supplied engines include the Rotax 503 twin-cylinder, two-stroke, air-cooled powerplant of and the Rotax 582 twin- cylinder, two-stroke, liquid-cooled powerplant of .

These flat rolls or sheets of metal are then punched out into round blanks that are a little larger than the coin being struck. The blanks are then subjected to an annealing process that softens the metal through heating to approximately 750 degrees Celsius (1400 degrees Fahrenheit) and are then slowly air cooled. They are then washed to remove residue from the annealing process and dried.

In 1957, Fiat in Italy launched the 479 cc 'Nuovo' Fiat 500 designed by Dante Giacosa with frontal styling by Claus Luthe. It was the first real city car. It had a rear-mounted air-cooled vertical twin engine, and all round independent suspension. Its target market was Italian scooter riders who had settled down and had a young family, and needed their first car.

The Dror was air-cooled and recoil-operated. The barrel uses a rotary bolt with multiple radial lugs mounted. The Drors is fired from an open-bolt in full auto for better cooling or from a closed-bolt in semi- auto for better accuracy. The Pattern 1 Drors had a physical resemblance to the Johnson, including the tall front sight and the barrel release.

The Donald has a tailskid undercarriage with main wheels mounted on split axles, hinged on a shallow V-strut attached to the fuselage underside. Faired, tapered legs are mounted on the lower fuselage longerons. The first prototype, with only from its Volkswagen 1.1 litre air-cooled flat-four engine, first flew on 16 June 1953. Two other Donalds were homebuilt from plans by different amateurs.

Two Chablis were built by Boisavia, the first F-PBGO making its first flight on 16 July 1950. These were powered by a 65 hp (48 kW) Continental A65 flat four-cylinder air-cooled engine. The Chablis was intended for construction by amateur builders using kits supplied by the firm. In the event, no further examples were completed and further development was not proceeded with.

It uses an air-cooled condenser to reduce water draw. It is located on a 186-acre former industrial area that was owned by NMPC and housed the former 376 MW coal-powered Albany Steam Station. NMPC sold the land to PSEG in 2000. In 2017, the Bethlehem Energy Center (BEC), as it is also known, injected 5,303 GWh of electric energy into the electric transmission system.

The World of Automobiles (London: Orbis Publishing, 1974), Volume 13, p.1491. In 1932, Nardi joined with Augusto Monaco to create the Nardi-Monaco Chichibio. It used an air-cooled 998 cc 61 c JAP of , more than the 1750 cc (107 in3) Alfa Romeos of its competition,Setright, p.1491. transversely mounted and coupled to a five-speed gearbox, but unusually, driving the front wheels.

Its fuselage was an oval-shaped stressed-skin semi-monocoque with the single-seat cockpit and its teardrop-shaped canopy positioned just aft of the air-cooled engine. Just behind the cockpit was a fuel tank. The large wing consisted of a two-spar center section with hydraulically-folded three-spar outer panels. A large dive brake was positioned on the trailing edge of the wing.

Common cylinder arrangements are from 1 to 6 cylinders in-line or from 2 to 12 cylinders in V-formation. Flat engines – like a V design flattened out – are common in small airplanes and motorcycles and were a hallmark of Volkswagen automobiles into the 1990s. Flat 6s are still used in many modern Porsches, as well as Subarus. Many flat engines are air-cooled.

Reeves who had been at Crossley Motors. This radical design had an air cooled, five cylinder, sleeve valve, radial engine of 1247 cc mounted at the front of a tubular steel lattice frame. The drive to the rear wheels was via an inclined shaft to a central 3 speed gearbox and then another shaft to the rear axle. Suspension was by transverse cantilever springs.

Five production aircraft were built at Shoreham, differing chiefly in the choice of engine. Three of them had 80 hp Armstrong Siddeley Genet II and one a 100 hp Armstrong Siddeley Genet Major. These were five-cylinder uncowled radials. One aircraft had, at different times, a de Havilland Gipsy I or II (100 hp and 120 hp respectively), upright in-line air-cooled engines.

The smaller sustainer engines are usually not equipped with a throttle, but instead have a cable to open decompression valves in each cylinder to allow the engine to turn freely for starting. Sustainer engines are typically two- stroke two-cylinder air-cooled engines in the range of 18–30 hp (14–22 kW). They are lighter in weight, and simpler to operate than self-launching powerplants.

For 1968, it was powered by an air-cooled, 320cc engine with a top speed of 25 mph. Following complaints of overheating and inefficiency, it was replaced for 1969 with a water cooled 367cc engine. There were common complaints about discomfort from its flat seat and minimally-padded Ski-Doo supplied stainless steel handle bars. After only two years on the market, it was discontinued. PWC.

BMW took over a license for manufacturing air-cooled radial engines from Pratt & Whitney on 3 January 1928. The nine-cylinder model Pratt & Whitney R-1690 Hornet was initially manufactured virtually unchanged under the designation BMW Hornet. Soon BMW embarked on its own development. The result was the BMW 132, essentially an improved version of the Hornet engine, that went into production in 1933.

This increased the compression to 8.5:1 and boosted power output to over the O-320's . The engine was later used in a number of airplanes and helicopters and also in amateur-built aircraft designs. The O-340 family of engines covers a range from to . All have a displacement of 340.4 cubic inches (5.58 litres) and the cylinders have air-cooled heads.

Söderbloms Gjuteri & Mekaniska Verkstad (Swedish for Söderblom's foundry and mechanical workshop) was founded in 1877 in Eskilstuna, Sweden. The company started manufacturing engines in 1900 with a 1.5 HP air-cooled engine for motorcycles. In 1901, the company started manufacturing automobiles under the leadership of CEO Knut Söderblom and head of sales Oskar Aspeling. The company also hired a German engineer, Bruno Büchner, as head of design.

The Tatra engine is an air-cooled, OHV, currently 12.7 litre 90° V8 120 x 140 mm diesel engine with direct fuel injection. It is turbocharged by one Holset WasteGate turbocharger, and equipped with an intercooler placed directly over the engine. The engine is equipped with a mechanically controlled in-line Bosch injection pump. Its roller crankshaft bolted together from individual segments belongs among unique technical solutions.

The Baby Great Lakes was designed by Barney Oldfield, and originally built by Richard Lane, to be a scaled-down homebuilt derivative of the Great Lakes Sport Trainer. The Baby Great Lakes is built using of steel tubing for the fuselage with aircraft fabric covering. The wings use spruce spars. The aircraft can accommodate engines ranging from the Continental A-65 to the Volkswagen air-cooled engine.

Kaiser created six prototypes with a 42hp engine, but including some unfavorable design trade-offs. Willys eventually produced even more radical designs. The Willys WAC (Willys Air Cooled) had three seats, built around a centrally mounted 24hp Harley Davidson engine, weighed only , but was noisy and not user-friendly. Still, it showed promise, and was further developed, eventually resulting in the Willys JBC, or 'Jungle Burden Carrier'.

It had a 9-cylinder air-cooled Polish Skoda Works licence-built Wright Whirlwind J-5A radial engine delivering 240 hp (179 kW) at take-off and 220 hp (164 kW) nominal, driving a two-blade wooden propeller, 2.7 m diameter (in SP-AFA – metal one). 190-litre fuel tank in a fuselage (600 l in SP-AFA). Cruise fuel consumption was 45–50 l/h.

In 1936 Lachassagne introduced the AL 6. This was a close relative of the AL 5 but powered by a Aubier-Dunne air- cooled, twin cylinder, inverted inline two-stroke engine. It was externally similar to the AL 5, though its dimensions and weights are not known, but it had a new undercarriage with split axles hinged on a transverse V-strut from the fuselage longerons.

With the rear wheel driven by a belt, the Model H was fitted with a air-cooled four- stroke single-cylinder engine. It was also the first Triumph without pedals. The Model H in particular, is regarded by many as having been the first "modern motorcycle". Introduced in 1915 it had a 550 cc side-valve four-stroke engine with a three-speed gearbox and belt transmission.

The weapon was much lighter compared to the M14 it replaced, ultimately allowing Soldiers to carry more ammunition. The air-cooled, gas-operated, magazine-fed assault rifle was made of steel, aluminum alloy and composite plastics, truly cutting-edge for the time. Designed with full and semi-automatic capabilities, the weapon initially did not respond well to wet and dirty conditions, sometimes even jamming in combat.

The HMG PK-16 is a Pakistani belt-fed air-cooled Gas operated Heavy machine gun designed and produced by the POF. It was first unveiled on 23 November 2016 on the IDEAS defence exhibition inaugurated by both PM Nawaz Sharif and COAS Raheel Sharif and visited by Federal minister of defence Khwaja Asif and MoDP Rana Tanveer Hussain. Its name might suggest its introduction in 2016.

The US version was to mount the newly developed Continental AVCR air-cooled V-12 diesel of . German versions originally used a similar Daimler- Benz model, but later moved to an MTU design of . The MTU unit could be easily swapped out of the tank, along with the drive train, in 15 minutes. Both versions could reach on their engines, compared to for the T-62.

Manderbach assembled the Framo vehicles until World War II. In 1949 Manderbach again built its own delivery vans, the Framo design retained. Manderbach wanted to change production to the air-cooled DKW engines, which were not available for him at the time. He was able to switch to the 1.2 liter Ford Taunus engine. Louis Manderbach died in 1949 and his son took over the company.

The wing was built around two wooden box spars; its ribs were also wooden and the skin was birch plywood. Long ailerons filled much of the outer panels' trailing edges. Like the wings the fuselage was wooden, with four longerons defining its flat-sided form; it, too, had stressed birch ply skin. A Train 4T four-cylinder, air-cooled, inverted straight engine drove a two-blade propeller.

The crew of three had open cockpits in the nose (front gunner), in front of the wing (pilot) and aft of the wing (rear gunner). The landing gear was fixed. The Bristol Jupiter VI air-cooled radial engines were installed without cowls on nacelles that were attached on top of the lower wing, at the innermost pair of struts. Each drove a two-bladed propeller.

The Mongoose is a five-cylinder, single-row, air-cooled radial piston engine. The engine features twin forward-mounted ignition magnetos and enclosed valve rockers, the cylinders being the same as those used for the earlier Jaguar engine.Gunston 1989, p. 18. An unusual feature of the Mongoose is the vertical position of the lower cylinder, a design thought likely to promote oil fouling of the spark plugs.

The M25Y is a single- cylinder two-stroke, displacement, air-cooled, gasoline engine design, with a poly V belt reduction drive. The reduction drive has optional reduction ratios of 2.2:1, 2.3:1, 2.5:1, 2.6:1, 2.7:1 and 2.88:1. The M25Y employs a single capacitor discharge ignition, a WB37 diaphragm carburettor and produces at 7900 rpm. The weight is including the exhaust system.

One of the revelations of the Frankfurt Motor Show in September 1961,nsu prinz 4 1962 at audi.com/corporate/en/company/history/models Accessed 28 December 2016 the Prinz 4 replaced the original Prinz. Its new body closely resembled the then fashionable Chevrolet Corvair, but was of course much smaller. Like the original Prinz, it was powered by a two-cylinder air-cooled engine in the rear.

The same engine was offered with an ethanol option. In 1985, the air-cooled engine of the Gol was replaced by a 1.6-litre (and later 1.8-litre as well) longitudinally-mounted water-cooled gasoline inline-four engine from the Passat. By May 1982 the Voyage 1.5 was upgraded to 1.6. In 1984 a water-cooled Voyage 1.8 ("Super") was launched as a higher-level option.

The "radiator" cap was actually the fuel tank filler, which led to problems when mechanics unfamiliar with air-cooled cars topped off the fuel tank with water. In 1925 a more refined version came featuring stronger valve gear, a better system of lubrication, and enclosed pushrods. Front-wheel brakes became an option. The company introduced a Super Sports model in 1925 with a 1320 cc engine.

Both crew members wore spacesuits on the Voskhod 2 mission, as it involved an EVA and used an inflatable airlock. This allowed cosmonaut Alexei Leonov to exit and re-enter the craft. It was needed because the vehicle's electrical and environmental systems were air- cooled, and complete capsule depressurization would lead to overheating. The airlock weighed , was in diameter, high when collapsed for launch.

The Chasle YC-10 was designed by Yves Chasle and built by Charles Pagès. It was a low wing cantilever monoplane, with straight edged, slightly tapered wings. Originally these were square tipped and without dihedral but after early flight trials streamlined wing tip bodies called salmons and also dihedral were added. It was powered by a Rolls Royce Continental O-200-A air-cooled flat-four engine.

The M1918 is a selective-fire, air-cooled automatic rifle using a gas-operated, long-stroke piston rod actuated by propellant gases bled through a vent in the barrel. The bolt is locked by a rising bolt lock. The weapon fires from an open bolt. The spring-powered cartridge casing extractor is contained in the bolt and a fixed ejector is installed in the trigger group.

All of the turbines are manufactured by General Electric. It uses an air-cooled condenser to reduce water draw. It is located on a 193-acre former industrial area, the former Mid-Hudson Recycling Center, which was destroyed in a massive 1996 fire. It is fueled by natural gas supplied from a trunk pipeline, one of many that are located along the east coast.

The Type 80 chambers and fires the 7.62×54mmR round. It is a gas- operated, air-cooled, belt-fed, fully automatic firearm. It can fire on both the tripod and the foldable bipod on the gas tube below the barrel. Belts are used from 100-round boxes in the light machine gun configurations, and from 200- or 250-round boxes in tripod-mounted applications.

Instead of the Ninjas ZX-11's alloy frame, the bike had a steel double cradle frame with a removable front member for engine removal. The motorcycle had a more relaxed seating position and leg position than the ZX-11D/ZZR-1100 or the air-cooled GPZ1100 of the early 1980s .The official Kawasaki designation was ZX1100E. It also was offered in 1996 as an ABS model.

The Helicon engine's 72° layout differs from Buell's previous V-twins, which were based on 45° air-cooled Harley-Davidson Sportster motors, modified for greater efficiency and output. The 1125R includes a number of unconventional design attributes. The patented frame design houses the bike's fuel. The single, eight-piston front brake, called ZTL2, has a inverted rotor that is directly attached to the front wheel rim.

During this time, the crew was based at Bredower Naval Barracks. With the working-up completed, the boat was fueled and took on board a consignment of 15 electric and eight air-cooled torpedoes before departing for Kiel on 27 July. Around this time the boat was reassigned to Gunther Kuhnke's 10th U-boat Flotilla for front-line service, although this only became official on 1 September.

The Speedfight 2 was introduced in 2001 after the success of the original model. The designs of the front panel, rear panel and light are different on the two models. The Speedfight 2 is available in air-cooled and liquid-cooled variants. The model was also equipped with anti-dive front suspension The Peugeot Speedfight 2 2000-2004 has a Gurtner carburetor instead of a Dellorto carburetor.

Beyond the midplane level, all connections are optical. Racks have two midplanes, thus 32 compute drawers, for a total of 1024 compute nodes, 16,384 user cores and 16 TB RAM. Separate I/O drawers, placed at the top of a rack or in a separate rack, are air cooled and contain 8 compute cards and 8 PCIe expansion slots for InfiniBand or 10 Gigabit Ethernet networking.

The blades of the three-stage turbine's wheels, also blisks, are air-cooled from the inside. The jet nozzle is fixed with an interior cone. Auxiliary drives are mounted on a mounting plate behind the inlet, which also has the connections for starter motor/generator, oil and fuel pumps, engine speed control and tachometer. There are also optional drives for an AC generator and a hydraulic pump.

Bajaj Avenger Street 150cc The Bajaj Avenger is a cruiser style motorcycle designed and manufactured by Bajaj Auto in India. It draws the styling and other design cues from the Kawasaki Eliminator which had an air-cooled, single-cylinder Kawasaki engine and was sold at a premium. It was launched with a 180 cc engine, which has subsequently been increased to 200 cc and then 220 cc.

The Zip 125 had an air-cooled two-valve variant of the Piaggio group's LEADER (Low Emissions ADvanced Engine Range) engine. The 125 model was also equipped with side lights. In late 2005 a four stroke Hi-Per4 equipped 49 cc Zip 50 4t was announced. The 4t was restricted for some markets via electronics, a washer in the front transmission pulley and a smaller main jet.

In Britain, locomotives working on roadside steam tramways were required by law to have condensers. Water tank condensers (as above) were sometimes used but air-condensers were more common. A steam tram engine usually had a full-length roof and this was surmounted by a nest of air-cooled copper tubes in which the exhaust steam was condensed. Kitson & Co. made many engines of this type.

The later ME24 engines were seen in a variety of Mitsubishi's lower end Kei cars and trucks, until production ended in late 1972. Due to ever tighter anti-pollution legislation as well as a more demanding customer base, the air-cooled ME24 eventually made way for more modern engines. When installed in the A100/100V Minicas, the ME24 was referred to as the "Yellow" engine.

At the 1954 Motor Show in London Kieft Cars displayed a motor described by Bill Boddy as: "the Kieft/Norton air-cooled flat-four 1½-litre which gives over 100 b.h.p." Motor Sport, November 1954, Page 614. This was a version of the Butterworth motor fitted with Norton cylinder heads. Ian Richardson successfully used this engine during the 1970s in the Moonraker drag racing motorcycle.

Analog Cylinder Head Temperature gauge A Cylinder Head Temperature gauge (CHT) measures the cylinder head temperature of an engine. Commonly used on air- cooled engines, the head temperature gauge displays the work that the engine is performing more quickly than an oil or water temperature gauge. As the engine works at high speed or uphill, head temperature will increase quickly. The meter can be digital or analog.

Its drilling rigs were used in addition to the Soviet Union also in Albania, Romania, China and several Arab countries. In 1955, the plant was placed under the USSR Oil and Gas Industry Construction Ministry, which focused on the construction of construction machinery. In 1963, the plant started manufacturing air-cooled heat exchangers. In 1971, the plant was named after the communist politician Johannes Lauristin.

The M2 has varying cyclic rates of fire, depending on the model. The M2HB (heavy barrel) air-cooled ground gun has a cyclical rate of 450–575 rounds per minute.Dunlap, Roy F., Ordnance Went Up Front, Samworth Press (1948), pp. 310–311: the official rate during WWII was 450–575 rpm, but it was extremely rare to encounter a M2HB that exceeded 550 rpm.

The Avionette was powered by an air-cooled, , four-cylinder, upright inline Sergant A engine, which was geared down to produce at 3,200 rpm. It was enclosed in a duralumin cowling. Behind the engine the fuselage had a rectangular section, formed by four longerons connected with frames, and was plywood covered. Its open cockpit was over the wing at mid-chord; a photo shows a streamlined headrest.

There were simple parallel cabane struts between the upper wing centre section and the upper fuselage longerons. Ailerons were fitted only to the upper wing. The C.27 was powered by an Le Rhône 9C nine cylinder air-cooled rotary engine, driving a two blade propeller and with a cowling which surrounded its upper three- quarters. Behind the engine the fuselage had a cross-braced beam structure.

The C.128 was again very similar but powered by a Salmson 9AC, a nine-cylinder, air cooled radial engine. This had a smaller diameter than the rotaries and was mounted in a tapered nose with its cylinders exposed. There was a 14% increase in empty weight from the C.127 and a slight increase in span and area. At least five were built or converted.

The RW-8 was conventional in layout, and had mixed construction (steel and wood frame with canvas and plywood covering). The crew of two, sitting in tandem, were in an open cockpit, with individual windshields. Twin controls were fitted. Power came from a 4-cylinder air-cooled 90 kW (120 hp) straight engine PZInż, Junior (licence built Walter Junior) (82 kW /110 hp nominal power).

The motorcycle was sold until 2009 in the United States (and 2010 in Canada.)Motor Scooter Guide The Vino 125 has an air- cooled single-cylinder 4-stroke SOHC engine. The engine has a fan for supplemental cooling. It has a Mikuni BS carburetor with an auto-choke and carburetor heat device. Emissions controls are a catalyzed muffler, AIR Injection system, and an evaporative fuel canister.

This wing design proved to be very inefficient. Power was provided by a Clerget 9Z nine-cylinder air cooled rotary engine and it was to be armed with two Vickers machine guns. The original version had two cabane struts of long chord length supporting the upper wing. Four similar type interplane struts were used between the upper three wings, all of which had ailerons.

In 1929, Menasco designed his own engine, the 4-A, the first of what was to become Menasco's main product line, the inverted, in-line engine. Menasco designed and built a variety of four- and six-cylinder inverted air-cooled aircraft engines, some with supercharging.Parker, Dana T. Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II, pp. 122-4, Cypress, CA, 2013.

The Tatra 54 is an automobile launched by Tatra in 1931. An economy version of the Tatra 52, it was replaced in 1933 by the Tatra 75. The car was powered by an ohv air-cooled four-cylinder boxer motor of 1465 cc, positioned at the front, and giving a claimed output of . Power was delivered to the front wheels via a four-speed gear-box.

Air-cooled aircraft version of the M1917. Developed during the First World War, the M1918 arrived too late, but became the dominant weapon of its type in US service until the development of the M1919. It features a heavier barrel, but lighter barrel jacket as compared to the M1917. A sub-variant, the M1918M1, was developed as a flexible version of the fixed M1918.

Air-cooled engines have may be an advantage from a thermodynamic point of view due to higher operating temperature. The worst problem met in air- cooled aircraft engines was the so-called "Shock cooling", when the airplane entered in a dive after climbing or level flight with throttle open, with the engine under no load while the airplane dives generating less heat, and the flow of air that cools the engine is increased, a catastrophic engine failure may result as different parts of engine have different temperatures, and thus different thermal expansions. In such conditions, the engine may seize, and any sudden change or imbalance in the relation between heat produced by the engine and heat dissipated by cooling may result in an increased wear of engine, as a consequence also of thermal expansion differences between parts of engine, liquid-cooled engines having more stable and uniform working temperatures.

The Yamaha XT660Z Ténéré is a dual-sport motorcycle manufactured from 2008 to 2016 by Yamaha. It featured a single-cylinder engine, which was also used in the XT660R, XT660X, MT-03 ( 2006–2014), Jawa 660 Sportard, Jawa 660 Vintage and Aprilia Pegaso 650 Trail (post 2007) models. Though not sold in the US or Canada and some 40 kilos heavier than the original, air-cooled Ténéré from the early 1980s, many fans saw the 660Z as a return to form for Yamaha, following the demise of the air-cooled Teneres and the less popular 5-valve iteration which replaced them. The low-rpm electronic fuel injection glitches present in previously listed machines using the same, 660 engine were ironed out and the 660Z could reliably average 25kpl (72mpg Imperial, 60mpg US) which equated to 600 km or nearly 400 miles on a single tank.

T2c in Brazil The T2c, with a roof raised by about was built starting in the early 1990s for the Mexican, South American and Central American markets. Since 1991, the T2c has been built in México with the water-cooled 1.8 L inline four-cylinder carbureted engine—easily identified by the large, black front-mounted radiator—and since 1995 with the 1.6 L air-cooled engines for the Brazilian market. Once production of the original Beetle ended in late 2003, the T2 was the only Volkswagen model with an air-cooled, rear-mounted boxer engine, but then the Brazilian model shifted to a water-cooled engine on 23 December 2005. There was a 1.6 L water-cooled diesel engine available from 1981 to 1985, which gave fuel economy of 15 km/l to 18 km/l—but gave slow performance and its insufficient cooling system led to short engine life.

Although Eiji Toyoda was initially keen to take advantage of the, at that time innovative, FF concept (front-mounted engine with front-wheel drive), it proved technically too complicated for Toyota engineers to be able to complete within the allotted time, so the decision was made to switch to more conventional FR layout. The Publica was inspired by the successful Citroën 2CV which also used a 2-cylinder, air-cooled, horizontally opposed engine, with front-wheel drive. In spite of the fact that the government sources announced that significant tax breaks would be made for cars with engine displacements of less than 500 cc, Toyota decided that such a small engine would provide insufficient power on the highways, and increased the planned displacement to 700 cc. The resulting engine was an air-cooled 697 cc ohv 2-cylinder boxer which produced , and was known internally as the Toyota U engine.

It had a clean cantilever spatted undercarriage. The wings could be folded at wing root hinges, back along the fuselage sides. The aircraft could be powered either by a closely cowled 112 kW (150 hp) Siemens-Halske Sh 14a seven-cylinder radial engine (M.29a) or an air-cooled inverted inline Argus As 8R (a high-powered racing version of the Argus As 8) of the same power (M.29b).

The Kawasaki GPz1100 B1 and B2 are motorcycles that were manufactured by Kawasaki in 1981 and 1982 respectively. Both models featured a four-cylinder, two-valve air-cooled engine design with a capacity of 1,089 cc. This engine was an evolution of the powerplant used in the previous Kz1000 series, itself descended from the Z1. In 1983 the GPz1100 was completely revamped in both cosmetic styling, suspension and updated engine.

The pilot sat in a front cockpit and the flight test observer in another one aft of the wing. Power was supplied by six ILO F 12/400 air-cooled two-stroke engines driving three bladed propellers, mounted along the wings. The model was completed early in 1944, registered as BQ+UZ and fitted with a temporary wheeled undercarriage of ten small wheels fitted with low-pressure tyres.

The splitter gearbox is an unsynchronised, three-shaft gearbox with gearshift sleeves. It has an on-road gear, an off-road gear, and an additional gear for switching front-wheel drive. A dry diaphragm-spring single-disc clutch, type T20K/DZ, transmits the torque from the engine to the gearbox. The LO 1801 A is powered by an air- cooled, straight-four, OHV, carburetted LO 4/1 otto engine.

"A New Small Engine", Flight, 28 February 1935, pp.218-9. Like all the Cirrus engines, the Major was an air-cooled inverted four-cylinder inline design. Aimed at the same market for a robust, reliable and affordable light aircraft engine, it retained many proven design features of the originals while making many improvements. Cylinder barrels were of forged steel while the individual heads were of light alloy.

Consequently, the CPUs' cores are used to allocate tasks to the GPUs rather than directly processing the data as in conventional supercomputers. Titan runs the Cray Linux Environment, a full version of Linux on the login nodes that users directly access, but a smaller, more efficient version on the compute nodes. Titan's components are air-cooled by heat sinks, but the air is chilled before being pumped through the cabinets.

Rollo Sociable (1913) The Rollo Car Co. was an English maker of cyclecars based in 140 Conybere Street, Birmingham and active between 1911 and 1913. For 1913 three models were offered by the company. The hp named the Pony had a single-cylinder 549 cc air-cooled engine made by Precision and had a single seat. The weight was 336 lb (152 kg), and in 1913 it cost 70 guineas.

This was approved and prisoners were used for facilities construction (bomb shelters, etc.), and to supplant manufacturing labor. This practice heretofore was not common at other larger German companies, though others followed suit including Mercedes-Benz and MAN. The vehicle range was for military use, including the Steyr RSO Raupenschlepper Ost with an air-cooled 3.5 L V8 engine designed by Ferdinand Porsche, who worked for the company at that time.

Later models (only the 2.7GHz) were equipped with a Panasonic liquid cooling system which was much more reliable. The liquid cooling system fits into the case where the heat sinks would normally go, so there is no easy way to distinguish the liquid-cooled versions from the air-cooled, although most, but not all, of the liquid-cooled machines have a sticker inside warning about the possibility of leakage.

An air cooled cathodic protection rectifier connected to a pipeline. Cathodic protection markers over a gas pipeline in Leeds, West Yorkshire, England. Hazardous product pipelines are routinely protected by a coating supplemented with cathodic protection. An impressed current cathodic protection system (ICCP) for a pipeline consists of a DC power source, often an AC powered transformer rectifier and an anode, or array of anodes buried in the ground (the anode groundbed).

Chase Motor Truck Company (1907-1919), founded by Aurin M. Chase, was a manufacturer of trucks in Syracuse, New York. The vehicles were known for their air-cooled engines and simplicity of design. The company also produced a utility wagon in the form of an automobile, which could be converted for use in business or pleasure. With a few minor changes the car could also be utilized as a commercial wagon.

The firm York Safe and Lock was negotiating with Bofors to attain the rights to the air-cooled version of the weapon. At the same time Henry Howard, an engineer, and businessman became aware of it and contacted RAMD W. R. Furlong Chief of the Bureau of Ordnance. He ordered the Bofors weapon system to be investigated. York Safe and Lock would be used as the contracting agent.

All variants were powered by a single Wright J-5 Whirlwind air-cooled radial engine, although the prototype was initially reported as having a J-5. ;Skyway (ATC 2-49):Prototype, two built, one (msn 101) destroyed before being licensed and one (msn 100, NX7857) converted to Blackhawk standard. ;Coach:Cabin variant, one built (msn 102, NX146E). ;Blackhawk (ATC 135):Main variant, 11 built, including one converted from Skyway.

97-8 and had much in common with the ten cylinder engine. An air-cooled motor, its cylinders were made of cast iron, with integral cooling fins. The pistons and their rings were also cast iron, machined inside and out.Vivien, 1920 Part 4 Ch 3 Conical seats for the inlet and exhaust valves were ground into the flat cylinder head, the nickel steel valves being of the poppet type.

The powerplant is a Japanese, twin cylinder, air-cooled, four-stroke, dual-ignition HKS 700E engine. This engine choice provides similar reliability, smoothness and fuel economy to the Rotax 912, but at a much lower cost. With the HKS 700E engine the aircraft is designated as the Air Creation Trek 700E. The Trek has an empty weight of and a gross weight of , giving a useful load of .

1924 Autocrat 10/12 The Autocrat was a British car manufacturer operating from 1913 to 1926. The company operated from premises in the Balsall Heath area of Birmingham. Unusually for the time the company seems to have been run by two women, Ivy Rogers and Miss Howell. The first cars in 1913 were cyclecars powered at first by Peugeot and later by JAP air cooled V-twin engines.

Krause Publications. 2000. page 326The Encyclopedia of Weapons of World War II. Chris Bishop. Sterling Publishing Company. 2002. page 245 & 246 In itself the MG 34 was an excellent weapon for its time: an air-cooled, recoil-operated machine gun that could run through belts of 7.92×57mm Mauser ammunition at a rate of 850 rounds per minute, delivering killing firepower at ranges of more than 1,000 meters.

They can also run counter- rotation for installation in twins to eliminate the critical engine issue. A water-cooled DeltaHawk engine has been successfully fitted to a Rotorway helicopter, weighing the same as an air-cooled petrol engine of similar power and being capable of maintaining that power to 17,000 feet.Delta D2 Johnson, Pam. page 46 Pacific Wings. Accessed 2 January 2010 GAP Diesel Engine is a NASA development.

It is gray and is longer than the Roaring Bull V. It also has a Deutz diesel air-cooled engine and a hydraulic drive system. According to Captain Donald Lebo, the trip is shore to shore, about nine-tenths of a mile, and takes about 20 minutes. Passenger traffic in 2009 was above normal because the water level was high and operations did not have to shut for low water.

The engine is a four-cylinder four-stroke, horizontally-opposed, displacement, fuel injected air-cooled, direct-drive, gasoline engine design. It produces , with an 8.9:1 compression ratio. The engine is not type certified and is therefore intended for homebuilt aircraft. In March 2019 the engine type was withdrawn from service and all customer engines were subject to a mandatory, immediate buy-back by the manufacturer to remove them from service.

The engine is based on the Volkswagen air- cooled engine. It is extensively modified for aircraft use. This modification consists of a quad CDI ignition (8 coils), new and enlarged #4 bearing, custom made crank shaft and cam shaft, custom made cylinder heads and other modifications.EAA Experimenter, EAA Experimenter The engine is delivered completely assembled and test run from the factory (it is not delivered as a kit).

The Draggin' Fly was designed to be easy to build, to have good short field characteristics and to have control characteristics matched to the skills of less experienced pilots. A four-cylinder Volkswagen air-cooled engine was selected for reliability and ease of maintenance. The sole example was constructed over ten months without plans, though a rib jig and propeller plot were used. It was first flown in May 1972.

Five examples of the Fi 97 were built. Three aircraft were fitted with the Hirth HM 8U, 250 hp inverted V8 engine, and two used the Argus As 17A, 225 hp inverted 6-cylinder inline engine. Both engines are air-cooled. The plane had STOL capabilities and the most significant design aspect was the wing's high-lift devices to enable the aircraft to be flown at low speeds.

The D2 features a single three-bladed main rotor, a two-seats-in side-by-side configuration enclosed cockpit with a windshield, skid-type landing gear and a four-cylinder, air-cooled, two-stroke, turbocharged DeltaHawk DH180 diesel engine made by DeltaHawk Engines, Inc.. The aircraft fuselage is made from welded steel tubing and covered in a composite fairing. Further details about the design have not been released.

Logan is the name of a small automobile in the cyclecar category that was built in 1914 only by the Northwestern Cyclecar Works (or Northwestern Motorcycle Works) in Chicago, Illinois. It weighed about , had a wheelbase of , and used wire wheels. Power came from an air-cooled engine with two cylinders made by Spacke, delivering , following the then-usual power formula. It had friction transmission and belt drive.

The KR175 ran on a Fichtel & Sachs air-cooled single cylinder two-stroke engine positioned in front of the rear wheel, just behind the passenger's seat. The engine was started with a pull rope as standard, but there was an option of an electric starter. The electric starter became standard in 1954. The transmission was a sequential, positive-stop type with four speeds and no synchronization nor reverse gear.

Air-cooled motorcycles often rely heavily on oil-cooling in addition to air-cooling of the cylinder barrels. Liquid-cooled engines usually have a circulation pump. The first engines relied on thermo-syphon cooling alone, where hot coolant left the top of the engine block and passed to the radiator, where it was cooled before returning to the bottom of the engine. Circulation was powered by convection alone.

As time passed, more engine manufacturers moved to the enclosed crankcase engine. Companies like Briggs and Stratton were also producing lightweight air-cooled engines in the 1/2 to 2 HP (.37 - 1.5 kW) range and used much lighter-weight materials. These engines also run at much higher speeds (up to approximately 2,000-4,000 RPM) and therefore produce more power for a given size than slow flywheel engines.

Traditionally, Beiben trucks are equipped with Weichai engines and Fuller FAST transmissions in most markets. Certain models are also equipped with the ZF 16S151 transmission and Deutz air-cooled engines. ZF and Beiben has a joint venture in Chongqing China, to manufacture ZF Beiben Drivetech transmissions. The first Beiben Euro-5 truck is equipped with a Euro-5 Weichai WP12-430 engine, coupled with a ZF-Beiben 9T2280 transmission.

As well as producing aircraft and building Hispano- Suiza and Lorraine aero-engines under licence, Avia also designed and built their own radial engines. The Rk.17 was a 9-cylinder supercharged model, rated at 360 hp. It was a nine-cylinder version of their Rk.12. It was a conventional air-cooled radial: nitrided steel barrels with integral fins were screwed into heat treated Y alloy heads.

Similar to the prototype, the production car was a wingless B.E.2c fuselage stripped of various fittings, and equipped with two ash skids in place of the wheeled undercarriage. Mounted at the front of the car was an air-cooled Renault engine driving a diameter four-bladed propeller. The pilot was seated behind the observer, who also served as the wireless operator. A camera was fitted, British Airship Design.

1980 XR200 The XR200, a development of the XL185 trail bike, was produced from 1980 until 1984. The XR200 had a modestly enlarged ohc 2-valve 6-speed air-cooled engine with kick-start only. Suspension was conventional, like the XL185s, but with better quality components and more travel. Although the XR200 power output was modest, the bike was small and light and it suited less experienced riders.

The single cylinder air-cooled engine produces 8bhp at 7000rpm and maximum torque at 8.77Nm at 5500rpm. The scooter gets the V-Matic transmission and can be started using kick start as well as self-start option. With the recently updated Honda Eco Technology (HET) the scooter has company claimed efficiency of 60kmpl. In 2018, the scooter received a minor update from Honda which included new instrument console and LED headlamp.

With peace it was decided to branch out into cyclecar manufacture and a car was designed by Albert Clarke, the brother-in-law of Charles Richardson. The car was powered by a V-twin, air-cooled engine with a choice of 980 cc JAP or 1090 cc Precision types. Both power units drove through a friction drive and belt to the rear axle. Later models used a chain drive.

Ormat's core technology is the Ormat Energy Converter (OEC) power generation unit. It converts low and medium temperature heat into electrical energy, with low or zero emission of CO2 and pollutants. The OEC's main components are a vaporizer/preheater, turbo-generator, air-cooled or water-cooled condenser, feed pump and controls. Ormat has installed more than 900 MW of geothermal and recovered energy generation (REG) power units, based on OEC technology.

The aircraft's installed power range is and the standard engine is the Rotax 503, although the Kawasaki 440, Volkswagen air-cooled engine and the Half VW have also been used. Partial kits and construction kits were available in the late 1990s, but today the aircraft is only offered as plans.

A bevel gear was placed immediately after the clutch and a mechanical or hydrostatic reduction gear, which enabled it to operate at low (less than 2 km / h) speeds. It had two PTO shafts - rear and side. These features, as well as its good performance, led to the tractor being widely adopted throughout the USSR. The engine is air-cooled which reduces the risk of overheating and freezing.

The Lawrance Aero Engine Company was founded in 1917.Gunston, p. 125 After the end of World War I, the Lawrance engineers worked with both the Army and the Navy in developing their L-1 into a nine-cylinder radial engine, which became the 200 hp Lawrance J-1. It was the best American air-cooled engine at the time, and passed its 50-hour test in 1922.

The unfaired version of the GS500 was first sold in the UK in 1988 (model code GS500EJ) and the following year's model (code GS500EK) was released for sale in Europe and North America. It was equipped with an air-cooled parallel twin-cylinder engine derived from the earlier GS450. In the motorcycle market, the GS500 occupied the low end of Suzuki's mid-sized range for over twenty years.

The MS.350 made its first flight on 8 February 1936, piloted by Michel Détroyat, who was a well known aerobatic pilot. He demonstrated it in public on 17 May at a meeting in Saint-Germain, Paris. Its development was protracted, lasting until October 1937. At some early stage the original engine was replaced by a Renault 6Q, a rather similar 6-cylinder inverted air-cooled inline engine producing .

Two years later the Puma tooling and rights were sold again, this time to Alfa Metais Veículos. During the Alfa Metais period of ownership, the GTB was renamed to the AMV, while the small Puma cars were now called AM1 (Coupé) and AM2 (Spider). The AM1 and AM2 were actually a revived version of the 1983 and 1984 P 018, fitted with the VWB air-cooled 1,584 cc flat-four.

The engine is a twin cylinder four- stroke, horizontally-opposed, , air-cooled, gasoline engine design, with a mechanical gearbox spur gear reduction drive with a reduction ratio of 2.5:1. It employs electronic ignition and produces continuous at 5750 rpm. The engine management system is a six-sensor computer and the engine is optimized to drive a propeller. The engine was initially displayed at AirVenture, Oshkosh, Wisconsin in 2001.

The Nexth complies with the Fédération Aéronautique Internationale microlight rules. A later version will comply with US light-sport aircraft rules. The design features a cantilever mid-wing, two seats in side-by-side configuration, retractable tricycle landing gear made from titanium and a single Rotax 912ULS four cylinder, liquid and air-cooled, four stroke engine in tractor configuration.

A stretched bodywork prototype 500 Lăstun was exhibited at the 1989 Bucharest trade fair. Another prototype from the early 1990s featured hubcaps, body-coloured bumpers, and head restraints.

The S-7 was two-seater wire-braced monoplane powered by a Gnome air-cooled rotary engine. Construction began in early summer of 1912 and completed in July. The pilot sat in the rear cockpit with a passenger seated in a forward compartment in a tandem arrangement. The fuselage was enclosed in plywood and the aircraft used components taken from the S-6A including the main wing, tail and landing gear.

A recent addition has been a class for air-cooled monoshock bikes, this covers machines up to around 1990. A competition event is called an "observed trial" or "trial" (not plural), unless referred to as an "observed trials event". A newer name for the sport, MotoTrial, is used by some organizations. However, it was recently dropped by the Federation Internationale de Motocyclisme as a name for its observed trials competitions.

The MG 51 is a short-recoil-operated, locked breech, air-cooled and automatic only, belt-fed weapon. It uses a locking system with a two-piece bolt and dual locking flaps located in the front part of the bolt. These flaps engage the cuts made in the short barrel extension to provide rigid locking. Upon recoil, the flaps are retracted toward the center of the bolt, to unlock it.

The air-cooled four-cylinder engine was installed transversely across the motorcycle chassis, predating the bestselling fours from Honda and Kawasaki. The heart of the MV Agusta four- cylinder is the crankcase rack. The crankshaft, cylinder and cylinder head were mounted on it. The rack took the nine-piece crankshaft in six bearing blocks, as well as the spur gears in the control tower for the double camshaft drive.

The series all share a common conventional landing gear design that is electrically retractable. The aircraft were initially powered by 1600 cc Volkswagen air cooled engines of using Lloyd Patner's gear reduction units driving 3-blade Fahlin props, but later Continental O-200 and Lycoming O-235s were used along with the Rotec R2800 radial engine.Plane and Pilot: 1978 Aircraft Directory, page 159. Werner & Werner Corp, Santa Monica CA, 1977.

The M48s built by American Locomotive used a Continental AV-1790-5C gasoline engine and either an Allison CD-850-4A or 4B cross-drive transmission. Additionally a two- cylinder, gasoline, air-cooled engine (sometimes referred to as the "Little Joe" by tank crews) was provided to power a 28 volt, 300 ampere generator when the main engine was not needed. Fuel capacity was providing a cruising range of about .

The powerplant is a horizontally opposed Lycoming six-cylinder design. It is a direct-drive or geared, air-cooled, and normally aspirated engine. The cylinders have steel barrels with aluminum heads, and the valves are operated by hydraulic lifters. The crankshaft is supported in an aluminum- alloy split case by four main bearings and one ball-thrust bearing, and lubricating oil is supplied from a 12 quart wet sump.

Sears had a very lenient return policy: cars were sold on a ten-day trial basis. The cars had an air-cooled, two-cylinder, horizontally opposed engine, similar to that later used on BMW motorcycles. The engine was located under the floorboards, beneath the driver’s feet, and started from a hand crank in the front. Early cars were rated at 10 hp, and later models developed 14 hp.

2006 Kawasaki Ninja ZX-10R Kawasaki's Aircraft Company began the development of a motorcycle engine in 1949. The development was completed in 1952 and mass production started in 1953. The engine was an air-cooled, 148 cc, OHV, four-stroke single cylinder with a maximum power of at 4,000 rpm. In 1954, the first complete Kawasaki Motorcycle was produced under the name of Meihatsu, a subsidiary of Kawasaki Aircraft.

Fabricator Brian Bulmer teamed up with two-stroke engine tuner Brian Wolley and rider Barrie Scully to develop a racing version of the Birmingham Scott air-cooled 350 cc twin, setting a record for the Barbon Hill Climb and achieving in a Motor Cycling test. The team also developed a 52 bhp water- cooled 500 cc version, but competition from Japanese two-strokes meant that the project was not fully developed.

Samuel Dalziel Heron (18 May 1891 – 10 July 1963) was a British born aerospace engineer who made major contributions to the design of piston engines. While working in Britain he carried out the first systematic research into air- cooled cylinders. In the U.S.A he contributed to the design of the Curtiss R1454, invented the sodium cooled poppet valve and became technical director for aeronautical research for the Ethyl Corporation.

Its 696 V-twin has the highest power output per cc of any Ducati air-cooled engine. The Monster 1100 was announced in September 2008. Based on the Monster 696, it comes with a larger 1078 cc engine, a single sided swingarm, radial brake calipers, larger forks and taller suspension. In 2009, Ducati sold over 12,000 696 models, the first of their motorcycles to sell over 10,000 bikes in one year.

James 1914, pp. 7-8 Besides the aforementioned differences to the contemporary Renault V-8 air cooled aviation engines, the De Dion-Bouton 78 hp engine very closely resembled their design. It had eight cylinders arranged in two rows of four cylinders inclined at 90 degrees to each other. The propeller shaft was geared down from the crankshaft by spur gears and rotated at half the engine speed.

De Havilland realised that half of this engine would make an air-cooled four-cylinder inline engine of just the right size and at low cost. He persuaded Halford to undertake its design and development. The cylinders, pistons, con-rods and gearing were taken from the Renault, with the valve gear based on the Airdisco, and a new five-bearing crankshaft and cast crankcase were designed.Taylor 1999, pp.74-5.

Avro also built motor vehicles in the immediate post-World War 1 era, including the three-wheeler Harper Runabout, as well as their own light car. Powered by a 1,330 cc 4-cylinder engine, wood and aluminium were used in an integral construction similar to an aircraft. Approximately 100 were built. In 1927 Alliott Verdon-Roe designed a two-wheeler car powered by a 350 cc Villiers air-cooled engine.

In 1948, GM returned and restored the Opel brand. Volkswagen is dominant in the popular market; it purchased Audi in 1964, which eventually led to the formation of today's Volkswagen Group. Volkswagen's most famous car was the small, beetle-shaped economical "people's car", with a rear-mounted, air-cooled engine. It was designed in the 1930s by Ferdinand Porsche upon orders from Adolf Hitler, who was himself a car enthusiast.

The B.E.2 was almost identical to the B.E.1, differing principally in being powered by a 60 hp (45 kW) air-cooled Renault V-8 engine and in having equal-span wings. Its new number was not allocated because it was considered a separate type. The numbers allocated to early Royal Aircraft Factory prototypes are more properly regarded as constructor's numbers than as type designations.Hare 2012, p. 23.

Previously Suzuki had primarily used a permanent magnet single phase alternator setup on its bikes so the new equipment was quite a step up for the GT series. The 380 and 550 engines were air-cooled with a system marketed by Suzuki as Ram Air. This system consisted of a cast aluminum shroud covering a modified cylinder head to direct the cooling air. The GT750 was liquid-cooled.

The KPV is air-cooled and fitted with barrel with a hard chrome plated bore. It uses a short recoil operation system with gas assistance and a rotary bolt. It can be fed with the 40-round metallic belt from either the left or right side. The barrel can be removed by turning the prominent latch on the forward end of the receiver and pulling on the barrel's carrying handle.

The front window was a single pane of flat glass with a single wiper mounted above the driver. Only right hand drive was offered. Toyota engineers (including Dr Kumabe) had visited Germany before World War II and had studied Porsche and Volkswagen designs (independent suspension, aerodynamic bodies, backbone chassis, rear-mounted air-cooled engines, economical production cost). Many Japanese companies had ties with Germany during the war years.

Wankel engines are internal combustion engines using an eccentric rotary design to convert pressure into rotating motion. These engines exhibit some features of both four stroke and two stroke engines. Lubrication is total loss, but there may be some variations. For instance, the MidWest AE series of wankel aero-engines were not only both water-cooled and air-cooled, but also had a semi-total-loss lubrication system.

One Douglas O-2, serial number 25-380, was modified for the new role as an attack aircraft. While the basic structure of the aircraft remained, there were several modifications made. The water-cooled Liberty engine (V-1650) of the O-2 was replaced by an inverted air-cooled Allison VG-1410 engine. The reason for this was that a water cooling system was seen as too vulnerable to enemy attack.

In the case of Voskhod 2, an inflatable exterior airlock was also added to the descent module opposite the entry hatch. The airlock was jettisoned after use. This apparatus was needed because the vehicle avionics and environmental systems were air-cooled, and depressurization in orbit would cause overheating. A solid-fueled braking rocket was also added to the parachute lines to provide for a softer landing at touchdown.

Available as a kei truck, it was based on the Honda TN360. The Vamos used a 354 cc 2-cylinder, mid mounted, air-cooled, overhead camshaft gasoline engine shared with the Honda TN360, N360, and the Z360. The Vamos was a competitor at the time to the Suzuki Jimny and the Daihatsu Fellow buggy. According to the article for this vehicle at Japanese Wikipedia, only 2,500 were sold.
