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
