In the mid-90s electronic igniters replaced the copper and iron transformer, solving many problems related to the old style transformer. This new technology in igniters would soon replace all old style transformers throughout the oil burner industry. The new igniters would run cooler so the output voltage could be increased from 10,000 to 20,000 VAC. This increase of voltage would be more reliable, reduce delayed ignition, run cooler and all while using less energy.

Just out of sight below the surface of the water, jets would allow natural gas to bubble to the surface. As the bubbles broke the surface, igniters hidden in the stones would cause the gas to burst into a high flame. Sensors would adjust the flow of gas and the operation of the igniters to accommodate weather (such as wind or rain). The second major change to the memorial's design involved the glass walls and bronze artwork.

When the GAU-8 is being fired, the smoke from the gun can make the engines stop, and this did occur during initial flight testing. Gun exhaust is essentially oxygen-free, and is certainly capable of causing flameouts of gas turbines. The A-10 engines now have a self-sustaining combustion section. When the gun is fired the igniters come on to reduce the possibility of a flameout.

She is reported to have responded to her sentence with such dignified calm that the chief judge permitted her to appeal. The sentence was commuted to life with hard labour. On March 6, 1942, Parsons was taken with several other prisoners for transport to Anrath Prison in Germany. Parsons was transferred to Wiedenbruck, where she worked on an assembly line creating plywood wings for small craft, then on a line assembling igniters for bombs.

The oxidizer and fuel preburners are welded to the hot-gas manifold. The fuel and oxidizer enter the preburners and are mixed so that efficient combustion can occur. The augmented spark igniter is a small combination chamber located in the center of the injector of each preburner. Two dual-redundant spark igniters are activated by the engine controller, and are used during the engine start sequence to initiate combustion in each preburner.

Laser ignition is considered as a potential ignition system for non-hypergolic liquid rocket engines and reaction control systems which need an ignition system. Conventional ignition technologies like torch igniters are more complex in sequencing and need additional components like propellant feed lines and valves. Therefore, they are heavy compared to a laser ignition system. Pyrotechnical devices allow only one ignition per unit and imply increased launch pad precautions as they are made of explosives.

The greater the distance the stick extends into the barrel, the greater the range. The principle involved is similar to that employed in adjusting the range of the Type 89 50 mm grenade discharger. To traverse, loosen the two wing nuts that secure the bipod, and swing the bipod feet around the area in front of the base plate. Finally, to arm explosive charge, insert the two friction-type pull igniters in the holes provided in the base.

The upper stage was powered by a single Merlin 1C engine modified for vacuum operation, with an expansion ratio of 117:1 and a nominal burn time of 345 seconds. For added reliability of restart, the engine has dual redundant pyrophoric igniters (TEA-TEB). The second stage tank of Falcon 9 is simply a shorter version of the first stage tank and uses most of the same tooling, material and manufacturing techniques. This saves money during vehicle production.

Now, to prevent the risk of explosion in many pressurized water reactor (PWR) containment buildings, a catalyst-based recombiner is installed that converts hydrogen and oxygen into water at room temperature before the hazard arises. In some commercial nuclear plants, hydrogen igniters have been installed to burn the hydrogen as it is generated, before it can reach a concentration and volume to create a dangerous explosion. Zirconium is a constituent of the uranium zirconium hydride (UZrH) nuclear fuel used in TRIGA reactors.

Glow plugs in model engines differ from those in full-size diesel engines. Full-size engines only use the glow plug for starting. Model engines use a glow plug as an integral part of the ignition system because of the catalytic effect of the platinum wire, on the methanol-base fuel they are designed to run on. Model engine glow plugs are also used as re-usable igniters in theatrical pyrotechnics and the special effects industry to remotely ignite pyrotechnic devices using flash and smoke composition powders.

When the afterburner is turned on, fuel is injected and igniters are fired. The resulting combustion process increases the afterburner exit (nozzle entry) temperature significantly, resulting in a steep increase in engine net thrust. In addition to the increase in afterburner exit stagnation temperature, there is also an increase in nozzle mass flow (i.e. afterburner entry mass flow plus the effective afterburner fuel flow), but a decrease in afterburner exit stagnation pressure (owing to a fundamental loss due to heating plus friction and turbulence losses).

In addition to the firearms, the complex and highly planned attack involved several improvised explosive devices. Using instructions obtained via the Internet and the Anarchist Cookbook, Harris and Klebold constructed a total of 99 bombs.Columbine Report, These included pipe bombs, carbon dioxide cartridges filled with gunpowder (called "crickets"), Molotov cocktails, propane tanks converted to bombs, car bombs, and diversionary bombs. For ignition, they used kitchen matches and model rocket igniters as well as timing devices built from clocks and batteries for the propane, car, and diversion bombs.

The Ariane 2 first flew on 31 May 1986, during which it carried the Intelsat VA F-14 satellite. However, the third stage had a partial ignition followed by another ignition above nominal pressure which led to the engine's failure. Because the upper stage of the Ariane 2 was shared with the other Ariane rockets, all flights were suspended until 16 September 1987. As a result of an investigation into the ignition irregularities, it was decided that installing more powerful igniters would sufficiently rectify the issue.

Hwacha loaded with singijeon projectiles. The hwacha's structure was very similar to a handcart, with a mobile wooden launchpad on the top containing 100 to 200 cylindrical holes, into which igniters like those of the sajeonchongtong (사전총통) were placed. The ammunition, similar to the ancient Chinese fire arrows, consisted of a 1.1 m long arrow with the addition of a gunpowder-filled paper tube attached to the shaft just below the head. Approximately 100 projectiles were loaded and launched in one volley, and had a range of up to 2000 m.

The focus of the research activity was on designs, interactions and materials required for electromagnetic launchers. In 1999, a collaboration between ARL and IAT led to the development of a radiometric method of measuring the temperature distribution of railgun armatures during a pulsed electrical discharge without disturbing the magnetic field. In 2001, ARL became the first to obtain a set of accuracy data on electromagnetic gun-launched projectiles using jump tests. In 2004, ARL researchers published papers examining the interaction of high temperature plasmas for the purpose of developing efficient railgun igniters.

Some fuel/oxidiser combinations ignite on contact (hypergolic), and non-hypergolic fuels can be "chemically ignited" by priming the fuel lines with hypergolic propellants (popular in Russian engines). Gaseous propellants generally will not cause hard starts, with rockets the total injector area is less than the throat thus the chamber pressure tends to ambient prior to ignition and high pressures cannot form even if the entire chamber is full of flammable gas at ignition. Solid propellants are usually ignited with one-shot pyrotechnic devices. Once ignited, rocket chambers are self-sustaining and igniters are not needed.

The town is noted for a fatal accident in 1966 in which a B-52 Stratofortress of the Strategic Air Command crashed after a midair collision with a KC-135 Stratotanker plane, causing radioactive contamination after its payload of four hydrogen bombs (H-bombs) was dispersed and crashed. There were four thermonuclear weapons in the bomber. The high- explosive igniters in two of these bombs detonated on impact, spreading radioactive material, including deadly plutonium-239, over a wide area of the Spanish countryside, but safety mechanisms and electronics prevented nuclear explosions. The third H-bomb landed via parachute into a stream, where it was relatively intact and was recovered.

The fuel injection volume was then accurately controlled by a computer using this detection signal to achieve lean air–fuel ratio feedback. For optimal combustion, the following items were applied: program independent injection that accurately changed the injection volume and timing for individual cylinders, platinum plugs for improving ignition performance with lean mixtures, and high performance igniters."Toyota 4A-ELU engine", "240 Landmarks of Japanese Automotive Technology" website The lean-burn versions of the 1587cc 4A-FE and 1762cc 7A-FE 4-cylinder engines have 2 inlet and 2 exhaust valves per cylinder. Toyota uses a set of butterflies to restrict flow in every second inlet runner during lean-burn operation.

The motor is capable of multiple restarts, due to a spark ignition system as opposed to the single use pyrotechnic or hypergolic igniters commonly used on some contemporary engines. Though rated for up to 16 starts and 40+ minutes of firing time, on the H-II the engine is considered expendable, being used for one flight and jettisoned. It is sometimes started only once for a nine-minute burn, but in missions to GTO the engine is often fired a second time to inject the payload into the higher orbit after a temporary low Earth orbit has been established. The original LE-5 was built as a second stage engine for the H-I launch vehicle.

The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the side, earth, or ground electrode(s). Spark plugs may also be used for other purposes; in Saab Direct Ignition when they are not firing, spark plugs are used to measure ionization in the cylinders – this ionic current measurement is used to replace the ordinary cam phase sensor, knock sensor and misfire measurement function. Spark plugs may also be used in other applications such as furnaces wherein a combustible fuel/air mixture must be ignited. In this case, they are sometimes referred to as flame igniters.

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.
