摘　　要：将一定量的乙醇按照体积百分比和汽油混合构成乙醇汽油,目前在我国部分地区已推广使用。在对发动机不做任何改动情况下,在一台电控发动机台架上做了测试和分析。试验表明相对于纯汽油,在尾气排放中,混合燃料降低了HC排放,NO_(x)化合物的排放有所增加。在动力方面E10的动力性较纯汽油高,E20动力性略有降低。A certain amount of ethanol is mixed with gasoline according to the volume percentage to form ethanol gasoline,which has been popularized in some areas of my country.Without making any changes to the engine,tests and analyses were done on an electronically controlled engine bench.Experiments show that compared with pure gasoline,mixed fuel reduces HC emissions and increases NOx compound emissions in exhaust emissions.In terms of power,the power of E10 is higher than that of pure gasoline,and the power of E20 is slightly lower.
