autoignition temperature

The minimum temperature needed for self-sustained combustion in absence of a spark or flame, at which the vapours from a volatile liquid will ignite spontaneously.

The autoignition temperature (AT) is of interest to the Occupational Safety and Health Administration (OSHA) (US), which lists ATs in its Materials Safety Data Sheets, see there.

However, under boosted conditions, particularly with the additized fuel, autoignition temperatures are much lower, resulting in relatively slow kinetic rates which can significantly affect the duration of the heat-release.
Cooking with solid fuel, like wood, produces creosote and deposits this highly combustible material in exhaust hoods and ducts, where its low flash point and autoignition temperatures can create a fire hazard.
Potential hazards associated with fuel, including flammability, detonation limits, and autoignition temperatures must be considered inside and around the engine in case of unintentional fuel leakage.
