M15甲醇汽油在4G15S汽油机上的试验研究

Experimental Research on the Performance of the Methanol-gasoline M15 Used in the Gasoline Engine 4G15S

在4G15S汽油发动机上分别对燃用M15甲醇汽油与燃用93#汽油时的动力性、经济性、常规及非常规排放性能等进行了试验研究。试验表明,该汽油机与M15甲醇汽油具有良好的适应性;与燃用93#汽油相比,动力性略有下降,燃油消耗率增加,尾气排放中CO,HC,NOx明显降低,甲醛排放增加。

This paper makes a research of power performance,fuel efficiency,conventional and unconventional emission behavior on the 4G15S engine by respectively using M15 methanol-gasoline and93# gasoline.The experiment results show that the power of M15 methanol-gasoline used in engine is slightly reduced compared with the 93# gasoline used in gasoline;the fuel efficiency is much increased,but with the better economy;the emission of CO,HC and NOx is obvious reduced,but that of HCHO is increased evidently.
