Now we need to realize that gasoline engines are clean and low fuel consumption because we face the problems of global warming and lack of resources. It is well known that most of hydrocarbon emission and other harmful emission are produced just after cold start of engines. In order to reduce the hydrocarbon emission, we examined how the atomization characteristics of a fuel injector affect the hydrocarbon emission from gasoline engine in cold-start condition. Two types gasoline engine were used. One is a direct injection engine with slit-nozzle injectors, and Ihe other is a port fuel injection engine with multi-hole nozzle injectors. Atomization characteristics of injector were changed when the hydrocarbon emission was measured. It was found that the better atomization characteristics, the lower hydrocarbon emissions from the engines.
