Ignitors are normally used only at engine start, until the flame in the combustion chamber becomes self-sustaining. With continuous ignition, instead, the ignitors are continuously sparked every second or less, so that if a flameout occurs, combustion can immediately be restored.

Various ignition systems have been used, including hot-tube ignitors and spark ignition. Most modern gas engines are essentially dual-fuel engines. The main source of energy is the gas-air mixture but it is ignited by the injection of a small volume of Diesel fuel.

Then, in 1997, with the introduction of Strong's new, compact 1 kW-3 kW switching power supply it became clear that the existing AC ignitor assemblies in the original Super Trouper (and not Super Trouper II's) were not functionally compatible with the new power supplies. Over the next several years, DC ignitor assemblies began to gradually replace the older AC ignitors.

Marshall was born in Whigham, Grady County, Georgia, United States. He sang in a gospel choir as a child, and later learned to play the drums to back another gospel group. Marshall soon became more interested in the electric guitar, and had lessons to assist him in playing the instrument. He became proficient enough to form his first band, The Blues Ignitors.

The board conducted a test of an oxygen tank rigged with hot-wire ignitors that caused a rapid rise in temperature within the tank, after which it failed, producing telemetry similar to that seen with the Apollo 13 Oxygen Tank 2\. Tests with panels similar to the one that was seen to be missing on SM Sector4 caused separation of the panel in the test apparatus.

A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbines, a gear reduction system, and the shaft output. The gas generator creates the hot expanding gases to drive the power section.

The SNEB appears to have been fit operationally only once, when it was mounted on some British Army Aérospatiale Gazelles during the Falklands War in 1982, but it appears none were actually fired. The SNEB was also cleared for carriage by many other aircraft used in the conflict, but due to the possibility that shipboard radars might fire the electrical ignitors, most used an older Royal Navy 2-inch rocket design instead.

The compressor housing was a welded steel sheet construction, divided in two parts. The upper half contained the fuel- and engine control systems, later also the automated starter control and ignition coils for two ignitors located in the combustion chamber's upper area. ;Engine control Engine control was handled by a fully automatic, compact commando unit using a proven Junkers single-handed lever action. In various states of flight, fuel throughput can vary greatly.

Krytrons and their variations are manufactured by Perkin-Elmer Components and used in a variety of industrial and military devices. They are best known for their use in igniting exploding-bridgewire and slapper detonators in nuclear weapons, their original application, either directly (sprytrons are usually used for this) or by triggering higher-power spark gap switches. They are also used to trigger thyratrons, large flashlamps in photocopiers, lasers and scientific apparatus, and for firing ignitors for industrial explosives.

Hot-tube ignitors had many problems, most caused by the sudden pressure changes in the tube because of the operation of the engine and the high temperature of the tube. It was extremely difficult to find materials that were both durable enough for these conditions and inexpensive. Also important was never setting the burner flame where it would heat the tube white hot, which would rapidly damage the tube and could cause it to burst explosively. This mistake was made often.

Older airbag formulations contained mixtures of oxidizers and sodium azide and other agents including ignitors and accelerants. An electronic controller detonates this mixture during an automobile crash: : 2 NaN3 → 2 Na + 3 N2 The same reaction occurs upon heating the salt to approximately 300 °C. The sodium that is formed is a potential hazard alone and, in automobile airbags, it is converted by reaction with other ingredients, such as potassium nitrate and silica. In the latter case, innocuous sodium silicates are generated.

Orders from the United Kingdom declined just before World War I. War was anticipated by his customers, so Linus Winterhalder agreed in the UK in London with his customers to grant a delay of payments from one month to three months. Orders then came in, but he did not receive any more payments after World War I began. The company was in financial danger. During the First World War production had to change to war material, especially ignitors for shells.

Typical film thickness - manufactured with thick film manufacturing processes for electronic devices - is 0.0001 - 0.1 mm. Thick-film circuits/modules are widely used in the automotive industry, both in sensors, e.g. mixture of fuel/air, pressure sensors, engine and gearbox controls, sensor for releasing airbags, ignitors to airbags; common is that high reliability is required, often extended temperature range also along massive thermocycling of circuits without failure. Other application areas are space electronics, consumer electronics and various measurement systems where low cost and/or high reliability is needed.

This new solid-state power supply unit weighed in at approximately sixty-five pounds (30 kg), which was roughly one third the weight of its high reactance predecessor. Strong introduced the Super Trouper II model xenon follow spot in 1995 as the first new follow spot design since the xenon Gladiator III in 1983. With it, Strong also released a new "DC" ignitor assembly, which was a simpler and more reliable version of its predecessor: the "AC" ignitor. It allowed for a shorter ignition time and required less space than the standard AC ignitors found in standard Super Trouper followspots.

The earlier engines required the ignitors to be inserted through holes in the engine into the combustion chamber, but the new system allowed the fuel to be sprayed into the main injector. The fuel, triethylaluminum, was delivered in a cube with diaphragms that burst when the fuel flow in the injector reached a set threshold. Finally, the X-1 introduced a new lubrication system that added a small amount of additive to the RP-1 fuel as it flowed through the various components. This was fed under pressure into the various bearings in the turbopump system, both lubricating it and carrying away heat.

Although the freezing altitude at the time was at 5200 feet and the aircraft was flying in temperatures of −2 degrees, the plane did not have its anti-icing system activated. The possibility of ice accumulation on the engine would have existed until the aircraft had decreased its altitude to 2000 feet or less. At that point, the ice would melt, which could possibly flood the engine, the condition which did ultimately cause the accident craft's engines to flame out. This scenario may have been avoided if the ignitors on the operating engine were put on after the first engine flame out.

Inductive discharge ignition systems were developed in the 19th century as a means to ignite the air–fuel mixture in the combustion chamber of internal combustion engines. The first versions were low tension coils, then low- tension and in turn high-tension magnetos, which were offered as a more effective alternative to the older-design hot-tube ignitors that had been utilized earlier on hot tube engines. With the advent of small stationary engines; and with the development of the automobile, engine-driven tractors, and engine-driven trucks; first the magneto and later the distributor-type systems were utilized as part of an efficient and reliable engine ignition system on commercially available motorized equipment. These systems were in widespread use on all cars and trucks through the 1960s.

Hwacha launch pad, ignitors placed in the narrow section of each arrow to be fired Unlike the cannons or mortars used in Western warfare during Middle Ages and the 16th century, which required heavy iron balls, hwachas fired arrows which were thin and light, making it an easy-to-maneuver siege weapon. The holes in the hwacha's launching array ranged in diameter from 2.5 to 4 cm, which allowed thin Gungdo bow-like arrows to be fired and also admitted sajeonchongtong class igniters placed in the back side of the shooting board. Singijeon-class projectiles were small arrows designed by Korean siege engineers specifically to be used in hwachas. Called so (소), or "small", they possessed a pouch of black powder attached in the bottom near to the fletching section.

400 W metal-halide lamp shortly after powering up A "cold" (below operating temperature) metal-halide lamp cannot immediately begin producing its full light capacity because the temperature and pressure in the inner arc chamber require time to reach full operating levels. Starting the initial argon arc (or xenon in automotive) sometimes takes a few seconds, and the warm up period can be as long as five minutes (depending upon lamp type). During this time the lamp exhibits different colors as the various metal halides vaporize in the arc chamber. If power is interrupted, even briefly, the lamp's arc will extinguish, and the high pressure that exists in the hot arc tube will prevent restriking the arc; with a normal ignitor a cool-down period of 5–10 minutes will be required before the lamp can be restarted, but with special ignitors and specially designed lamps, the arc can be immediately re-established.

In June 2007, the ERD approved circular firing sites for use with vertically fired mortars with a safety distance of at least radius, plus distance adjustments for wind speed and direction.Natural Resources Canada Explosive Branch Bulletin #48 Loading of shells is a delicate process, and must be done with caution, and a loader must ensure not only the mortar is clean, but also make sure that no part of their body is directly over the mortar in case of a premature fire. Wiring the shells is a painstaking process; whether the shells are being fired manually or electronically, any "chain fusing" or wiring of electrical ignitors, care must be taken to prevent the fuse (an electrical match, often incorrectly called a squib) from igniting. If the setup is wired electrically, the electrical matches are usually plugged into a "firing rail" or "breakout box" which runs back to the main firing board; from there, the Firing Board is simply hooked up to a car battery, and can proceed with firing the show when ready.
