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。
채용기유차은태가재모의공황법（ASM）、기유차간역순태공황법（VMAS）、쌍태속법등대북경시불동행사리정적재용출조차미기배방진행근종검측，통과고핵오염물배방농도적변화，진행배방특성연구。결과표명，신차투입운행후，행사리정재15만공리내，각충시험방법측득CO、HC、NO적배방량균보지겁저수평；행사리정초과15만공리후，3충방법균측득CO、HC화NO적배방농도완만증가；행사리정재25만공리후，CO、HC화NO적배방량명현대폭도증가，차량배방악화。
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 150000 kilometre. After 150000 kilometre CO, HC and NO emission concentrations began increasing. After 250000 kilometre CO, HC and NO emission concentrations increased sharply.
