摘　　要：采用稳态工况法(简称ASM法),选择了市场份额较大的2.0 L,1.5 L左右排量的在用小汽车6款共4 518辆进行尾气排放测试,对比分析了被测车辆的排放数据。结果表明6年车龄以上的被测车辆,其3种污染物排放随车龄增加而快速升高,而不同品牌汽车发动机ECU管理风格导致了污染物排放的差异,同时发动机工艺及技术对车辆污染物排放也有较大影响。This paper conducted emission tests of acceleration simulation mode （ASM） for about 6 types which have high market shares over 4 518 in-use gasoline cars with the displacements of 2.0 L and around 1.5 L, and the experimental data of these testing ears are compared and analyzed. Results show that the 3 pollutants increase rapidly with vehicle age when the vehicle age is over 6 years; the engine ECU management styles of different brand cars lead to the difference of the emission; and the techniques and technology of cars engine have great effects on the emission of cars.
