• This paper presents an experimental study on the phenomena of evaporation and ignition of a fuel-droplet impinging upon a hot surface. The experiment was made on seven kinds of fuels. It was revealed that cool flame is generated in n-heptane and diethyl-ether at a surface temperature range which is 300-400 K below that of hot flame generation. The surface temperature at which the cool and hot flames were generated was determined by applying a statistic method. Their delay times were also measured and then classified into physical and chemical delays by applying the statistic technique which was presented by Kumagai et al. The natures of both the cool and hot flame generation and the ignition temperatures measured by using the crucible method was discussed.
