电喷汽油机燃烧甲醇燃料的试验研究

Experimental Study on an EFI Engine Fueled with Methanol-gasoline

在发动机结构参数未做任何调整的情况下,通过发动机台架试验,研究了中、高比例甲醇汽油对电喷发动机动力性和燃油经济性的影响。试验结果表明:燃烧M30、M50、M85三种甲醇燃料与燃烧93#汽油相比,发动机的动力性和燃油经济性都下降,且随着甲醇掺烧比例的增加,动力性和经济性降低的越多。

Without any changes of the engine parameters,the engine power performance and fuel economic performance of the Electronic Fuel Injection（EFI） engine fueled with mid and high proportion methanol-gasoline were studied through the engine bench test.The experiment results show that compared with 93# gasoline,both power performance and economic performance decrease when burning M30,M50,M85,and the more the methanol＇s proportion the more the power performance and economic performance decrease.
