摘　　要：小负荷时经济性差，是火花助燃甲醇发动机存在的主要问题。以1130立式水冷直喷柴油单缸机为对象，研究了点火系统、压缩比、喷油嘴油线分布和喷油嘴针阀开启压力等因素对火花助燃甲醇发动机小负荷时经济性的影响，并将之与柴油发动机进行了对比分析。Bad fuel economy under light load is the main problem existing for methanol engine of spark assissted combustion. Effect of ignition system, compression ratio, fuel line distribution of injection nozzle and opening pressure of injection nozzle needle valve, etc. on fuel economy of the spark assissted combustion methanol engine under light load has been studied with a model 1130,single Cylinder, verticle water cooling, direct injection diesel engine as the research object. And analysis has been carried out in comparison with another diesel engine.
