摘　　要：总结了目前在汽油机上已经开展的有关乙醇/汽油混合燃料的试验研究,主要包括:燃用乙醇/汽油混合燃料对发动机的动力性、燃油经济性和排放性能的影响;催化转化器、过量空气系数(Φat)以及压缩比和点火时刻对燃用乙醇/汽油混合燃料时发动机的燃烧和排放特性的影响。最后对其发展和研究方向做出展望。The relevant research of ethanol-gasoline blends which has been developed currently on the gasoline engine is summarized in the following aspects： the effects of burning ethanol-gasoline blends to engine power, fuel economy and emissions; the combustion and emission characteristics which are effected by catalytic converter, excess air coefficient （Фat）, compression ratio and ignition timing when ethanol-gasoline blends is used. Finally new developments and future trends on the research are presented.
