Gasoline vapor ignition temperature

Webinner gas core is heated by diffusion of hot combustion products from the flame zone. Cracking can occur with the formation of small hot particles of carbon that give the flame its characteristic luminosity. If there is an oxygen deficiency and if the carbon particles are cooled to below their ignition temperature, smoking occurs. Web870°F to 1300°F (465°C to 704°C).
