The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

A large compost pile can spontaneously combust if improperly managed. Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition.

2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH 3) 3 CCH 2 CH(CH 3) 2.It is one of several isomers of octane (C 8 H 18).This particular isomer is the standard 100 point on the octane rating scale (the zero point is n-heptane).
"Rollover" or tongues of fire appear (known as "angel fingers" to firefighters) as gases reach their auto-ignition temperatures. There is a rapid build-up (or "spike") in temperature due to the compound effect of rapidly burning (i.e., deflagrating) gases and the thermal cycle they produce. This is generally the best indication of a flashover. [2]
Autoignition occurs when the temperature of the fuel/air mixture becomes too high before it is ignited by the flame front. The compression stroke is intended to compress the products before the flame ignites the mixture.
The winter warm-up routine started decades ago when vehicles were more prone to stalling in frigid temperatures, according to Carfax. Up until the 1980s, Carfax said vehicles had carburetors, a ...

Temperature controlled furnace Loss on ignition (LOI) is a test used in inorganic analytical chemistry and soil science , particularly in the analysis of minerals and the chemical makeup of soil. It consists of strongly heating ( "igniting" ) a sample of the material at a specified temperature, allowing volatile substances to escape, until its ...
