The Compression-ignition processes of a propane/air mixture are said to change from the cool flame and to the hot flame reactions. In this study, a rapid compression machine and propane were used to provide the cool flame and the hot flame reactions. At a constant injection timing of a diesel spray, the equivalence ratio of the propane/air mixture was varied in the range of 0 to 0.4 which resulted in determining the ambient state at the time of injection, the state of cool flame or the hot flame. Ignition, combustion, the KL factor and flame temperature obtained by a two color method were analyzed on a diesel spray formed in the ambient state.
