In order to reduce hydrocarbon emissions of spark ignition engine, it is important not only to improve Catalyst conversion efficiency but also to reduce hydrocarbon emissions out-of-engine directly, during cold starting and warm up process. The purposes of this study are to evaluate the feasibility of a glow plug for EFE(Early Fuel Evaporator) and the behavior characteristics of gasoline spray is injected on the glow plug with room temperature and high temperature(250℃). Particle Motion Analysis System is used to measure the SMD and the dropsize distribution of Impinging spray and tree spray.
