Experiment Study on Thermal Ignition Delay Period of Gasoline-Air Mixture

In this paper, the thermal ignition delay period of the gasoline-air mixture under the condition of high temperature heat source and temperature-rising heat source in cave depots has been studied using experiment methods. The rules, scopes, and mechanism of thermal ignition delay period are got. It is found that: there is different delay period scope in different ignition model. The delay period for thermal explosion is the shortest, for thermal deflagration, the delay period is longer than that for explosion, usually seconds to a few hundred of seconds.The mechanism of delay period is unification of chemical kinetics and thermodynamics before ignition.
