Abstract

The ignition of n-pentane-air mixture at low temperatures is experimentally studied in a rapid mixture injection static reactor. The ignition process was monitored using a high speed color video camera. It is shown that introduction of platinum wire into the reactor eliminates the phenomenon of negative temperature coefficient; however Pt wire has no effect on the ignition delay time of thermal ignition of stoichiometric n-pentane-air mixture at lower temperatures.
