Ignition

Ignition occurs when the heat produced by a reaction becomes sufficient to sustain the reaction, whether it be a fire, an explosion, or nuclear fusion. By analogy, the sudden change from a cold gas to a hot plasma in a plasma source is also called ignition.

• In chemistry it refers to heating a material to the point that it spontaneously combusts.
• In nuclear fusion it refers to the conditions under which a plasma can be maintained by fusion reactions without external energy input. See Fusion energy gain factor.
• An ignition system is a method for activating and controlling the combustion of fuel in an internal combustion engine. For a car, it is initiated by turning the car's key in a lock to start the engine.
• In semiconductor processing, ignition is the process of starting up a plasma generator. In DC plasma systems, this involves a transition from voltaic arcing to sustained and delocalized plasma generation. RF and microwave systems must produce sufficient power at the proper frequency to generate usable plasma, which generally requires some adjustment of the equipment.
• Ignition was a hip hop song by R. Kelly.
• Ignition is a humorous racing game for PC published in 1997 by UDS (Unique Development Studios).
• Ignition Entertainment is a computer video games company founded in founded in 2002 which is currently focusing on games for the Nintendo DS and Sony PSP

Fire: Fire is a form of combustion. Most typically, the word fire refers to the combination of the brilliant glow and large amount of heat released during a rapid, self-sustaining exothermic oxidation process of combustible gases ejected from a fuel. The flames are a body of plasma that releases heat and ...

Explosion: An explosion is a sudden increase in volume and release of energy in a violent manner, usually with the generation of high temperatures and the release of gases. An explosion causes pressure waves in the local medium in which it occurs. Explosions are categorized as deflagrations if these waves are...

Nuclear fusion: In physics, nuclear fusion is the process by which two nuclei join together to form a heavier nucleus. It is accompanied by the release or absorbtion of energy depending on the masses of the nuclei involved. The iron nucleus has the largest binding energy of all nuclei and so is the most stable. The...
