摘　　要：对捷达电喷发动机在外特性和4 000r/min负荷特性下燃用93#汽油、乙醇汽油(E10,E20)、甲醇汽油(M15,M30)和液化石油气(LPG)时的排放性能进行了试验研究,主要测试了CO,HC和NOx3种常规污染物.试验结果表明:发动机燃用M30可降低显著降低NOx和HC的排放质量浓度;发动机燃用LPG时,CO的排放质量浓度明显低于其他燃料.Experiments of the exhaust emission from EFI engine were carried out by using LPG,M1S, M30,E10,E20 and 93 gasoline. The results of the experiments have shown, compared the 93# gaso- line and other substitute, HC and NOx emissions of the engine that used M30 were especially reduced; compared the 93# gasoline and other substitute, CO emissions of the engine that used LPG were de- tracted especially in the low rotation speed.
