The act of igniting, kindling, or setting on fire.

The state of being ignited or kindled.

A process which initiates the combustion of the compressed air/fuel mixture in the combustion chamber. In a spark-ignition engine, the mixture is ignited by an electric spark; in a diesel engine, the self-igniting mixture must be preheated by glow plugs when a cold start is performed.

Firing; setting on fire; provision for firing.

Ignition is the second album released by The Offspring on October 16, 1992. Some sources incorrectly list March 8, 1993 as the release date. Although not widely recognised, it is a firm fan favorite and contains the track "Dirty Magic", held as one the band's finest achievements.

Ignition is a PC game released in 1997 by Virgin Interactive. It features miniature cars, much like Death Rally.
