摘　　要：对一台4102QB型直喷式柴油机分别燃用柴油及甲醇-柴油混合燃料时的动力性和排放特性进行了对比试验。试验结果表明,在柴油机参数和基本结构不作任何改动的情况下,随着混合燃料中甲醇添加比例的增加,柴油机的动力性有所下降,烟度和CO的排放量明显降低,HC和NOx的排放量有所增加,但变化幅度不大。A contrast test on the power performance and emission characteristics of a 4102QB direct injection diesel engine fueled with pure diesel and diesel-methanol blends is conducted. The test results indicate that, under the conditions of without any change in parameters and basic structure of diesel engine, with the increase of methanol proportion in blended fuel, the engine power slightly lowers, the emissions of soot and CO markedly re- duce and the emissions of HC and NOx have marginal rise.
