摘要: 以低温地区典型城市辽中南城市群的重型柴油货车为研究对象,结合辽中南城市群的环境条件、行驶特征等交通信息,通过车载测试方法、指南法和IVE模型建立辽中南城市群本地化的重型柴油货车排放因子数据库.结果显示:重型柴油货车冬季各道路类型上的平均车速均大于夏季,且车流量在市郊路最大,其次是市区路和高速路.重型柴油货车各污染物排放因子随排放标准提高而降低;50%负载时各污染物排放是无负载状态的1.4~5.5倍;冬季各污染物排放是夏季排放的1.31~1.64倍.对于国Ⅲ重型柴油货车,CO,NOx和PM排放因子实测值分别是指南法和IVE模型的0.5~0.8倍和1.1~1.3倍.

Abstract: Based on the environmental conditions, driving characteristics and other traffic information, the emission characteristics of heavy-duty diesel trucks in Mid-Southern Liaoning Urban Agglomerations was analyzed, a typical city in low temperature areas. The on-board test results were utilized to localize the emission factors of Guidebook and IVE model, and the emission factor database of heavy-duty diesel trucks in Mid-Southern Liaoning urban agglomerations was obtained. The results show that the average speed of heavy-duty diesel trucks on various road types in winter is higher than in summer, and the traffic flow is the largest on suburban roads, followed by urban roads and highways. The pollutant emission factors of heavy-duty diesel trucks decrease with the increase of emission standards. When the heavy-duty diesel truck is 50% loaded, the pollutant emissions are 1.4~5.5 times that of the no-load state. The emission of pollutants from heavy-duty diesel trucks in winter is 1.31~1.64 times that in summer. For National III heavy-duty diesel trucks, the measured results of CO, NOx and PM emission factors are 0.5~0.8 times and 1.1~1.3 times of Guidebook and IVE model, respectively.

Key words: low temperature area; heavy-duty diesel trucks; on-road test; comparative analysis of emission factors; localization
