| 摘 要： | 在OEM-2100基础上开发了一种机动车道路排放实时测试系统,并在实际道路上进行了轻型车的实时排放测试。计算了路段排放因子和排放总量,分析了车辆各行驶工况所占时间和排放量比例以及平均排放率,研究了各工况下机动车尾气污染物的贡献率,为准确测定交通流中单车污染物提供一种可行的方法。该测试系统为建立排放模型提供数据依据,对于评价交通控制改进措施和智能交通系统对排放的影响具有重要的意义。

| Abstract: | A kind of realtime vehicle emission testing system based on the OEM2100 was developed to test the emission of lightduty vehicle.Road emission factors and emission inventory were calculated for verifying whether the vehicle reaches the standard. Through analyzing the proportion of exhaust time and emission for each operation mode and the average emission rate,the contribution rate of each operation mode to the vehicle emission was analyzed providing a feasible method of exacttesting single vehicle emission in the traffic flow. |
