| 摘 要： | 采用汽油车稳态加载模拟工况法（ASM）、汽油车简易瞬态工况法（VMAS）、双怠速法等对北京市不同行驶里程的在用出租车尾气排放进行跟踪检测，通过考核污染物排放浓度的变化，进行排放特性研究。结果表明，新车投入运行后，行驶里程在15万公里内，各种试验方法测得CO、HC、NO的排放量均保持极低水平；行驶里程超过15万公里后，3种方法均测得CO、HC和NO的排放浓度缓慢增加；行驶里程在25万公里后，CO、HC和NO的排放量明显大幅度增加，车辆排放恶化。

| Abstract: | Acceleration simulation mode(ASM),vehicle mass analysis system(VMAS),double idling method and type certification method were used to test the emission of road running taxies at different travelled distance.The changes law of emission with travelled distance was used to evaluate the Exhaust Emission Characteristics.Testing results indicated that CO,HC and NO from test cars kept low emission level within 150 000 kilometre.After 150 000 kilometre CO,HC and NO emission concentrations began increasing.After 250 000 kilometre CO,HC and NO emission concentrations increased sharply. |
