摘　　要：根据汽车排放法规对CA10 2 0F小解放牌货车尾气中有害气体成分及排放量进行了测量 .分析了测试工况变化对整车排放的影响 ,并讨论了该车有害气体产生的主要工况 .结果表明 ,主要的HC、CO和NOx 分别产生于试验车的 3档减速、加速和稳速工况 ;控制试验车的整车排放应从高速大负荷的加速、减速和稳速工况入手 .Emissions of a light truck CA1020F are measured according to vehicle exhaust legislation.The influence of testing process variation to vehicle emissions is analyzed.Main processes that produce harmful emissions are discussed.Most HC,CO and NO x are respectively produced in the accelerating,decelerating and constant speed running processes at third gear.The accelerating,decelerating and constantspeed running processes during engine's high speed and heavy load conditions should be the main processes of reducing the truck's emissions.
