| 摘 要： | 车载排放测试设备OBS-2200先在实验室整车转鼓试验台上与定容采样系统CVS进行对比试验,验证了其对各项排气污染物测量的有效性后,装在选出的有代表性的74辆轻型汽油车上,沿选取的天津市区典型的行驶路线,对车辆的道路排放进行实时测试。依据获取的测试数据,分析了在用车辆的排放现状与车辆状况(采用的排放控制技术、车龄和行驶里程等)之间的关系;并对天津市在用车辆的排放特征进行了分析评估。

| Abstract: | First,a test is conducted on the chassis dynamometer in the lab for comparing the on-board emission measurement system OBS-2200 with CVS system to verify its measurement validity for major pollutants.Then the road test of 47 representative light-duty gasoline vehicles are performed on typical roads selected in Tianjin city with real-time operation emission measured.Based on test data measured,the relations between the emission behavior and the situation of in-use vehicles(emission control techniques used,age and traveled mileage of vehicles) are analyzed.Finally the emission features of in-use vehicles in Tianjin city are analyzed and evaluated. |
