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.

When applied to CDC, this same concept will ideally allow sufficient fuel/charge gas mixing before autoignition that LLFC is sustained, i.e., soot formation is entirely prevented for the duration of the combustion event.

Besides that, there are a few GSA researches assessing the entire autoignition process that plays important role in the validation of a detailed mechanism.
(2013) report increase in the operation range (rotations) of 2-S ICE, in comparison to 4-S ICE, using auxiliary control of autoignition. On the other hand, these authors highlight the significant reduction of emissions as the ethanol content increases in the fuel blend and also better thermodynamic and combustion efficiency, due to the reduction of thermal losses, with 5% more of efficiency in fuel conversion using Gasool A85.
Dimethylcadmium, however, requires a fairly large footprint of a spill before its natural oxidation in air generates enough heat to hit autoignition, and when it does, assuming you survived the blast, the combustion byproduct of cadmium oxide dispersed through the air in a haze is almost as bad as the dimethyl.
Due to the poor performance of syngas' autoignition, a small amount of diesel is injected into the cylinder of the engine to ignite the syngas.
Safely mitigating the dust hazards (autoignition of fine dusts is a recognized hazard in industrial settings), and preventing the potentially unhealthy off-gassing of carbon monoxide (CO) from stored pellets is the subject of research.

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.
The result is autoignition within the unburned gases in advance of the approaching flame front.
