利用车载排放测试系统（PEM S ），选取了2台满足国Ⅳ排放标准的柴油乘用车进行深圳典型道路工况下的气态污染物排放测试。被测气态污染物包括CO ，NO x ，HC。研究了速度、加速度和单位质量功率等参数对柴油车排放的影响，分析得出低速下高加速状态柴油车排放因子最大，并且单位质量功率与排放速率呈现良好的关联性，同时车辆的行驶里程对排放有一定的影响。

In the typical road condition in Shenzhen ,the emissions of CO ,NOx and HC gaseous pollutants were measured on two stage Ⅳ diesel passenger vehicles using a portable emission measurement system (PEMS) .The effects of speed ,accelera-tion and VSP (vehicle specific power) on diesel vehicle emission were researched .It was found that the emission factors were the maximum at low speed with high acceleration .In addition ,VSP showed a very good relation to emission rates .The vehicle mileage also had certain influence on emission .
