| 摘 要： | 采用美国20世纪90年代末期生产的汽车排放总量分析系统(Vmas),按汽车排放法规中规定的试验工况,对CA1020F汽车排气排放物进行测量和分析。结果表明,该系统用于汽车排放的测试分析是有效可行的;排气中HC主要产生于汽车减速工况,即油门突然减小、转速突然降低的工况,而CO和NO_x则主要产生于发动机负荷增大时的工况。

| Abstract: | The Vehicle Mass Analysis System(Vmas) was produced in the United Slates late 1990s. In this paper this system is used to measure and analyze the exhaust of a CA1020F truck according to test modes prescribed by exhaust legislation. The test result shows that it is viable to measure and analyze automobile exhaust with the Vmas. HC is mainly produced in the decelerating mode of test car, that is, the throttle valve has a sudden close and the engine speed have a rapid decrease. The main CO and NO, is produced when the engine power is increasing. |
