Gasoline can be ignited by even a tiny spark at temperatures as low as fifty below zero, but it merely evaporates at temperatures up to about four hundred seventy five to five hundred F. At that temperature, it ignites spontaneously.
An appropriate air-fuel ratio is also necessary. The minimum ignition temperature at atmospheric pressure for some substances are: carbon 400 C, gasoline 260 C, hydrogen 580 C, carbon monoxide 610 C, methane 630 C..
