| 摘 要： | 提出了成分权重的概念，并用它对直喷式柴油机１３工况排放试验的排放特性进行了比较详细的分析研究。结果表明，直喷式柴油机排放中各工况的成分权重具有一定的规律性，且两种全负荷工况下各种有害排放物的成分权重最大，是降低排放的主要目标。

| Abstract: | In this paper a concept of composition weighting is given,and comparatively de-tailed analysis on the features of thirteen mood exhaust emission test of direct injection diesel en-gine has been carried out by means of composition weighting. Result of analysis shows that the composition weighting possesses definite regularity under various exhaust emission test moods of DI Diesel engine,and composition weighting of harmful exhaust emissions under two full load test moods is the greatest,which is the main object of exhaust emission to be reduced. |
