摘　　要：选择一台1.5L涡轮增压直喷汽油发动机,在发动机台架上开展稳态循环试验,研究了燃用不同掺混比例乙醇汽油(E0、E5、E10)对汽油发动机排放污染物和油耗的影响。试验结果表明,随着乙醇掺混比例的增加,发动机CO和HC排放呈现逐渐降低趋势,且使用E10乙醇汽油对CO减排效果最为明显,相对于95号汽油下降13.9%。另外,随着乙醇掺混比例的增加,NOx排放有所增加,CO_(2)排放和发动机油耗略有升高。A steady-state cycle test was conducted on a 1.5L turbocharged direct-injection gasoline engine to investigate the effects of using different ethanol-gasoline blends(E0,E5,E10)on pollutant emissions and fuel consumption.The results showed that as the proportion of ethanol increased,CO and THC emissions decreased gradually,with the most significant reduction in CO emissions observed when using E10,which decreased by 13.9%compared to pure gasoline.However,NOx emissions increased slightly with increasing ethanol content,while CO_(2) emissions and engine oil consumption also increased slightly.
