摘　　要：对醇类燃料特性及其应用现状的分析研究表明,低浓度醇类燃料适合在不改变发动机结构的情况下使用;结合二冲程小型发动机的特点和使用情况,得出低浓度醇类燃料适合作为其替代燃料;通过对醇类燃料作为二冲程小型发动机燃料的可行性分析可知,燃烧醇类混合燃料可提高二冲程小型发动机的能量利用率、减少其尾气排放和降低排放温度。According to the research of the characteristics and application status of the alcohol fuels, the low concentrations alcohol fuel can be suitable used without changing the structure of the engine. Considering the characteristics and the application status of the two-stroke gasoline engine, the low concentration alcohol fuel adapts to the two-stroke gasoline engine as an alternative fuel. With feasibility analysis of alcohol fuel as a two-stroke engine fuel, it come to a conclusion that combustion alcohol mixed fuel can improve the energy efficiency and reduce exhaust emissions and the discharge temperature of two-stroke small engines.
