摘要
采用由美国加州大学Riverside分校开发的综合模式排放模型(CMEM)分析和研究北京市机动车污染物的排放特征,以9辆代表北京市典型技术类型的轻型机动车为实验车辆,收集了运行CMEM模型所需要的数据和参数.通过CMEM模型Access 2.02版本计算,得到了在不同交通行驶状况下北京市4类典型轻型机动车的CO2,CO,HC,NOx单车排放因子及各车型综合排放因子.通过与同一车辆的在路实测排放因子比较发现,用CMEM模型计算的CO,HC和NOx与实测排放因子及排放特征有较好的一致性,因此适用于计算北京市机动车CO,HC和NOx排放因子.
The vehicle emission characteristics of Beijing were analyzed and studied using Comprehensive Modal Emission Model （CMEM） developed by University of California at Riverside. The required data and parameters for CMEM were collected on the base of 9 light-duty vehicles with typical technology characteristics of Beijing. With CMEM Access version of 2.02, the CO2, CO, HC and NOx emission factors for 4 types of typical individual light-duty vehicles and comprehensive fleet in Beijing have been determined under different transport situations. The model result has shown an encouraging consistency compared with the real road measurement for the same vehicle. As a result, CMEM is proper to determine emission factors of CO, HC and NO, for the light-duty vehicles in Beijing.
