| 摘 要： | 在电喷汽油机上燃用低比例甲醇汽油混合燃料与燃用93#汽油进行对比试验研究。试验结果表明，汽油机燃用M15，M25混合燃料均比燃用93#汽油输出功率高，增幅为3．1％～7．7％；M15当量油耗率与93#汽油油耗率基本相等，M25当量油耗率降幅较为明显，最大降幅达16．8％；混合燃料有效热效率高于93#汽油；混合燃料比93#汽油CO放稍有降低，HC排放降低明显，NOx排放在中低负荷时有所改善，在大负荷时排放增加。

| Abstract: | Two kinds of low proportional methanol-gasoline blended fuels and the 93# gasoline were researched and contrasted by the experiment on an EFI engine. The results show that： the power of the engine with M15 or M25 increases by 3.1%-7.7＂% than 93# gasoline; the fuel consumption of M15 is equal with 93#, the fuel consumption of M25 decreases obviously, the max decreasing amplitude is 16.8% ; the efficient thermal efficiency of the blended fuel is higher than 93# gasoline; the CO and HC emissions of blended fuel are lower than 93# gasoline, the NOx emission is lower thah 93# gasoline but higher in the high load condition. |
