| 摘 要： | 选取南京城市隧道进行机动车PM10平均排放因子的测试研究。采用质量平衡模型和多元线性回归方法计算了4种车型PM10的综合排放因子。结果表明：隧道内机动车PM10平均排放因子为0.347±0.100 g/（km·辆）;大型车的PM10排放因子远高于其他车型的排放因子,其次是中型车和摩托车,小型车最小,其综合排放因子分别为1.440 g/（km·辆）、0.850 g/（km·辆）、0.790 g/（km·辆）和0.320 g/（km.辆）;在车速相似的情况下,本隧道实验所测机动车的PM10排放因子与国内隧道实验结果相仿,却远大于国外隧道实验结果。

| Abstract: | A tunnel test of Nanjing city was run to study PM10 average emission factor of motor vehicle,and the combined emission factor of 4 types of motor vehicles were calculated by adopting the mass balance model and multi linearity regression technique.The results showed that the average emission factor of motor vehicles was 0.347±0.100 g/（km·veh）.The PM10 emission factor of heavy duty vehicle was much higher than that of other types.The secondary was middle duty vehicle and motorcycle,and the least was light duty vehicle. The combined emission factors were 1. 440 g/（km · veh）,0. 850 g/（km · veh）,0. 790 g/（km · veh） and 0. 320 g/ （km · veh） respectively. Under the similar vehicle speed condition, the PMI0 emission factor tested in this study was similar to the domestic tunnel tests, but which was much higher than that abroad. |
