摘　　要：获得了汽油机燃用加入了添加剂的不同比例甲醇汽油和汽油的低负荷特性曲线和怠速排放数据。结果表明,甲93#醇汽油中加入添加剂后,汽油机燃用甲醇汽油尤其是中高比例甲醇汽油的怠速和低负荷性能与燃用汽油相当,油耗量93#和油耗率无太大变化,尾气经三效催化转化器转化后,常规排放相当,甲醇和甲醛排放接近零排放水平。Through the experiment on a gasoline engine fueled with traditional gasoline and different proportion of methanol-gasoline blended fuels with additives, the idle speed emissions and load characteristic curve were obtained. The results indicated that the power output didn＇t decrease generally at idle speed and low loads when the methanol-gasoline blends with additives were used; the fuel consumption behavior wasn＇t getting worse; the conventional emissions compared with gasoline were on the same level, and the side emissions of formal dehyde and methanol were reduced close to zero level after reaction of TWC.
