摘　　要：针对在增压中冷柴油机上燃用不同比例甲醇柴油对发动机燃烧和排放性能的影响进行了研究。结果表明:随着混合燃料中甲醇含量的增加,发动机动力性略有降低,使用经济性提高,缸内最大压力和温度降低,NOx和碳烟排放降低,HC排放增加;CO排放小负荷下大幅增加而在大负荷下略有降低。This paper is aimed at studying the influences of different proportions of methanol and diesel blends on the combustion and emission characteristics in turbocharged and inter-cooled diesel engine. The results shows that, with the proportion increasing of methanol, the power performance of the engine is a little lower, but the economical efficiency enhances. Both of the maximum cylinder pressure and temperature decline, NOx and scoot emissions descend, while HC emission increases, and CO emission increases by a large margin in small load and decreases a little in heavy load.
