摘　　要：以1台公交车柴油机为样机,研究了普通柴油和不同助燃剂添加比例柴油应用于柴油机时的动力性、经济性、烟度和排放特性。试验结果表明,添加助燃剂基本不影响发动机的动力性和燃油经济性,但可以改善烟度和PM的排放,燃用不同助燃剂添加比例柴油的烟度和PM排放差别不大。助燃剂的添加使NOx和HC排放略有上升,但影响较小。For a bus diesel engine,the performances of power,economy,smoke and emission were studied when diesel was blended with different proportions of combustion-supporting agents.The results indicate that the combustion-supporting agent has little influence on power and economy,but can improve the emission of smoke and PM.For different proportions of combustion-supporting agents,their effects of reducing smoke and PM emission are almost the same.Besides,the adding of combustion-supporting agent leads to a slight increase of NOx and HC emission.
