摘　　要：在不同供油提前角下进行柴油机燃用M15甲醇柴油混合溶液台架试验,对燃烧和排放特性进行分析。结果表明:随着供油的提前,M15甲醇柴油混合溶液燃烧时产生的缸内最高压力和最大放热率增加,所对应的曲轴转角前移;CO,HC及碳烟排放得到改善,但NOx排放大幅度上升。Experiments have been carried out to analyze the influences of different fuel supply advance angle on the combustion and emission characteristics of M15 methanol-diesel blend.The results shows that when the M15 methanol-diesel blend burnt with the fuel supply advance angle shift to an earlier angle,both of the maximum cylinder pressure and heat release rate increased,the corresponding crank angle shift forward,CO,HC,soot emissions have been improved,but a significant increase in NOX emissions.
