摘　　要：按照体积分数分别配制出不同比例的丁醇汽油混合燃料和乙醇汽油混合燃料,研究电喷汽油机在不作改动的情况下,燃用丁醇汽油和乙醇汽油混合燃料时的燃烧特性变化情况。研究结果表明:在不改变发动机任何参数的情况下,发动机燃用醇类汽油混合燃料指示热效率略有升高,充量系数略有下降,小负荷时,醇类燃料的循环波动较大,而大负荷时,其循环波动小于纯汽油,E30的燃烧持续期最短,而B30相对于汽油变化不大。Butanol/gasoline and ethanol/gasoline blended fuels are mixed based on volume ratio with gasoline. The effects of blended fuels compared with gasoline on the engine combustion characteristics are investigated through experiments. The experiment results show that, without any modification of the engine, indicated thermal efficiency increases and volumetric efficiency of engine fueled with alcohol/ gasoline blended fuel decreases slightly, and compared with engine fueled with gasoline, cyclic variation fueled with alcohol/gasoline blended fuel increases at low load and decreased at high load, and the combustion duration of E30 is shorter than other fuels, but B30 is almost unchanged compared with gasoline.
