| 摘 要： | 在成渝高速公路龙泉山隧道内设监测点，对进入隧道内汽车排出的污染物浓度、交通量、车种以及气象条件进行采样分析、计数、分类和 观测。根据实测数据，用隧道空气质量方程计算出我国高速公路汽车单车一氧化碳(CO)、总烃(THC)和氮氧化物(NOx)排放因子分别为 28. 7308 ±9. 225 ,3.1393±1.320和4.6507±1.928g/(km.辆)。与发达国家相比，我国高速公路汽车CO和THC排放明显高于发达国家高 速公路汽车排放水平，而我国高速公路汽车NOx排放因子却小于西方国家高速公路的测试结果。

| Abstract: | The measurement of pollutant concentrations from the vehicles insidethe Longquanshan free way tunnel ,the observations of meteorological conditions in the tunnel and the counting and classification of vehicles passing through the tunnel were conducted. The e mission factors of CO，THC，NOx from vehicles on freeway in China were 28.7308± 9.225 ,3.1393±1.320 and 4.6507± 1.928 g/ (km.veh), respectively ,which were derived from the tunnel air quality model based on the measured data .In comparison with the emission factors published by developed countries ,the CO and THC emission factorsof vehicles driving on freeway in China are much higher than thosein advanced countries . However ,the level of NOxemission is lower than that in the western countries . |
