The time it takes for a material to reach its autoignition temperature when exposed to a heat flux ″ is given by the following equation: [4] = [″], where k = thermal conductivity, ρ = density, and c = specific heat capacity of the material of interest, is the initial temperature of the material (or the temperature of the bulk material).
Oxyhydrogen will combust when brought to its autoignition temperature. For the stoichiometric mixture in air, at normal atmospheric pressure, autoignition occurs at about 570 °C (1065 °F). [4] The minimum energy required to ignite such a mixture, at lower temperatures, with a spark is about 20 microjoules. [4]
Acetone's auto-ignition temperature is the relatively high 465 °C (869 °F); [19] moreover, auto-ignition temperature depends upon experimental conditions, such as exposure time, and has been quoted as high as 535 °C. [80]
Autoignition temperature. 185 °C (365 °F; 458 K) Explosive limits: 1.2–90.5% ... Trichlorosilane (TCS) is an inorganic compound with the formula HCl 3 Si. It is a ...
Flashover occurs when the majority of the exposed surfaces in a space are heated to their autoignition temperature and emit flammable gases (see also flash point). Flashover normally occurs at 500 °C (932 °F) or 590 °C (1,100 °F) for ordinary combustibles and an incident heat flux at floor level of 20 kilowatts per square metre (2.5 hp/sq ft).

HCCI's autoignition event is highly sensitive to temperature. The simplest temperature control method uses resistance heaters to vary the inlet temperature, but this approach is too slow to change on a cycle-to-cycle frequency. [11] Another technique is fast thermal management (FTM). It is accomplished by varying the intake charge temperature ...
