| 中文摘要 |
| 选取典型城市隧道进行机动车排放因子测试,应用隧道试验原理,通过连续48h的现场采样监测,获得了隧道内机动车排放污染物NOx.CO、SO2、PM10、VOC和HC浓度、交通参数(车型、车速、交通流量)和气象参数(如风速、风量、温度、湿度)等实测数据.通过质量平衡计算出隧道内机动车NOx.CO、SO2、PM10和HC的平均排放因子分别为1.379、15.404、0.142、0.637、1.857g·(km·辆)-1.并在此基础上应用多元回归方法计算出8大类机动车各种排放污染物的单车排放因子.结果反映目前中国城市机动车污染物排放水平及各污染物排放特征. |
| 英文摘要 |
| Applying the principle of tunnel test to run a typical across-river tunnel test in Guangzhou city, 48h-online-monitor data include pollutant concentration, traffic activity and meteorological data were gained.The average motor vehicle emission factors of NOx, CO, SO2, PM10 and HC were calculated using mass balance which are 1.379, 15.404, 0.142, 0.637, 1.857g/km.vehicle respectively. Based on that, combined emission factors of 8 types of city vehicles were calculated using linear regression.The result basically showed the character and level of motor vehicle emission in Chinese city. |
