摘要 利用车载排放测试设备对某柴油乘用车进行了上海市典型道路的车载排放测试,分析了车辆在各典型道路上的行驶特征及车辆的THC、CO、NO x、CO2排放特性。结果表明,该柴油乘用车实际道路行驶工况具有平均车速度低、加(减)速度时间比大等特点,其加速(减)速的行驶时间和行驶里程分别占整个行驶时间的63.6%和行驶里程的83.2%;THC、CO、NO x、CO2排放率随车辆行驶速度、加速度的增加而增大,当车速超过90 km/h时,NO x和CO2的单位时间排放率急剧增加。 Emission test was made to a diesel-powered passenger car with on-board emission measurement system on typical roads in Shanghai.Its driving characteristic on typical roads and emissions characteristic of THC,CO,NOx and CO2 were analyzed respectively.The results show that the real driving characteristics of the diesel-powered passenger car feature lower average driving speed,and larger acceleration/deceleration ratio,which respectively accounted for 63.6 % of the entire driving time and 83.2 % of mileage.The emission rate of THC,CO,NOx and CO2 increase respectively with the increase of driving speed and acceleration.And when driving speed was over 90 km/h,the emission rate of NOx and CO2 increase dramatically.
