IVE机动车排放模型应用研究

对IVE模型进行了系统分析和介绍,以北京市为研究对象给出了模型的主要输入参数的确定方法和思路,运用IVE模型对北京市不同车型车队的排放进行计算。结果显示：公交车和卡车的排放因子明显较高,特别是颗粒物排放因子,分别为普通轻型车的14和44倍。北京市机动车的CO、VOC、NOx和PM的平均日排放总量分别为2767.4、182.5、353.8和7.1t。对于CO和VOC,普通轻型车的分担率分别为42.0%和34.7%;对于NOx和PM而言,卡车的贡献率最高,分别达到66.3%和83.0%。此外,比较了IVE模型与MOBILE6模型的方法和计算结果,讨论了IVE模型在我国的主要应用优势。

Application Study of IVE Vehicle Emission Model

This paper introduced IVE model and presented the method to quantify the main parameters by taking Beijing city as a case.Emissions from different vehicle fleets of Beijing were calculated using IVE model.The results show that emissions factors of buses and trucks were much higher,especially for PM,which were 14 and 44 times those of passenger cars.The daily CO,VOC,NO_x and PM emissions of vehicles in Beijing city were 2767.4,182.5,353.8 and 7.1t respectively. Common light duty vehicles were the main emission source of CO and VOC,with the contribution of 42.0% and 34.7% respectively,Trucks were the largest contributor of NO_x and PM emissions,with the contribution of 66.3% and 83.0% respectively.The methodology and calculating results of MOBILE6 and IVE model were compared,and advantages of IVE model's application in China were discussed.
