甲醇(CH3OH)和乙醇(C2H5OH)通常称为酒精。它们可以与汽油混合，为SI发动机提供燃料。酒精和汽油的混合燃料被称为汽油酒精。在一台三缸电控火花点火JL368Q3发动机上进行了燃用10(v/v)%、20(v/v)%和85(v/v)%甲醇/汽油和乙醇/汽油混合燃料时乙醇排放特性和燃料对碳氢化合物(HC)排放贡献的试验研究。实验结果表明，酒精排放速率的值(g酒精排放每公斤酒精燃料，g/kg。)是排气温度的指数递减函数，相关性很强；无论混合燃料中的乙醇含量如何，CH3OH的排放量都不超过8%，而C2H5OH的排放量不超过35%。无醇HC排放比乙醇排放高一个等级，在中高负荷时HC排放最低，甲醇/汽油混合燃料约为40%，乙醇/汽油混合燃料约为50%。汽油是乙醇汽油发动机HC排放的主要来源，甲醇对HC排放的贡献率不超过8%，乙醇对HC排放的贡献率不超过25%。[DOI：10.1115/1.4024716]
Methanol (CH3OH) and ethanol (C2H5OH) are generally called alcohol. They can be mixed with gasoline to fuel SI engine. The fuel blends of alcohol and gasoline are named gasohol. Alcohol emission characteristics and the contributions of fuel on hydrocarbon (HC) emission were experimentally investigated on a three-cylinder, electronic controlled, spark ignition JL368Q3 engine when it ran on 10 (v/v) %, 20 (v/v) %, and 85 (v/v) % methanol/gasoline and ethanol/gasoline fuel blends. Experimental results show that, the value of alcohol emission rates (g alcohol emission per kg alcohol fuel, g/kg.) is a decreasing exponential function of exhaust temperature with high correlation; regardless of the alcohol fraction in fuel blends, the CH3OH emission rate is no more than 8%, while that of C2H5OH no more than 35%. The emission rate of nonalcohol HC was one grade higher than the alcohol emission rate; the minimum HC emission rate occurs at middle and high engine loads, it is around 40% for methanol/gasoline blends and about 50% for ethanol/gasoline blends. Gasoline is the main source of HC emission of gasohol engine, methanol contributes no more than 8% while ethanol no more than 25% on HC emission. [DOI: 10.1115/1.4024716]
