| 摘 要： | 机动车综合排放因子是计算城市机动车污染物排放总量和排放分担率的基础，是降低城市机动车排放的重要依据，是控制城市道路交通污染的源头.根据宁波市区道路机动车运行工况的研究成果，利用加速模拟工况(ASM)排放测试系统，检测主要污染物HC，CO和NOx的排放浓度；依据试验车变速器和主减速器的结构参数，以及试验车在宁波市区道路运行时的档位分布计算排污值，并依据机动车的年代和车型分布对该值进行修正，计算宁波市区道路机动车综合排放因子.结果表明，宁波市区道路机动车主要污染物HC，CO和NOx的综合排放因子分别为5.89，21.22和18.91 g/(km·辆).

| Abstract: | The vehicle synthesis emission factors are the foundation of calculating total emission quantity and emission sharing rate of urban vehicle pollutants, the important basis for reducing the urban vehicle emissions, as well as the source to control the urban road transportation pollution. Through using the research results of the vehicle operating modes on urban roads of Ningbo City, the emission intensities of main pollutants such as HC, CO and NOx of testing cars under the urban road operating mode in Ningbo were obtained on the acceleration simulation operating mode (ASM) emission test system. The testing car pollution discharge values were calculated based on testing car design parameters of the transmission gearbox and the main gear box and on the transmission gearbox positiondistribution when the testing car moving on the urban roads of Ningbo. According to investigation results of vehicle age distribution and vehicle type distribution of the urban road transportation flow, the revision to the testing car pollution emission values was carried on. By the method, the urban road vehicle synthesis emission factors in Ningbo were obtained, being 5.89, 21.22 and 18.91 g/(km·veh). respectively for HC, CO and NOx. |
