摘要
介绍了计算机动车污染物排放因子的COPERTⅢ模型,并根据中国机动车实际构成、行驶工况和燃油特征确定了模型所需参数,然后应用该模型计算得到了2002年中国机动车排放CO、NOx、NMVOC和PM的排放因子.通过比较COPERTⅢ模式、MOBILE模式和台架测试得到的中国机动车排放因子发现,应用COPERTⅢ模型计算获得的排放因子更接近中国机动车实际排放情况.
The COPERTⅢ model for calculating the emission factors of motor vehicles is described and the required parameters are determined based on the actual categories, driving cycles and fuel oil characteristics of motor vehicles in China. And then the model is used to calculate the vehicle emission factors of CO, NOx, NMVOC and PM in China in 2002. By comparing the difference between the emission factors derived from the COPERT Ⅲ model, the MOBILE model and the chassis dynamometer, it is found that the emission factors calculated using the COPERTⅢ model is better close to those in the actual emission status in China.
