摘　　要：为了反映轻型车排放随发动机输出功率的变化关系,搭建轻型车车载排放测试试验平台,通过实际道路试验获取质量排放数据与对应的行驶状态数据;为了便于与交通仿真模型融合,将比功率分成10区,分析了3种污染物质量排放率随比功率分区的变化关系,并计算得到了10个分区内3种排放污染物的质量排放率。结论表明,轻型车3种污染物质量排放率与比功率具有很高的相关性;bin1～bin3对应着轻型车制动减速的情况,排放速率最慢;bin6～bin10对应着轻型车车速高以及急加速度情形,排放速率最高;研究得到的不同比功率分区下的质量排放率可以作为与交通仿真模型结合来量化区域排放的依据。In order to analyze the relationship between light-duty vehicle emissions and engine power, establishment of on board emission test platform of light-duty vehicle, getting the data of mass emission rate and driving conditions through actual road experiment; in order to facilitate traffic simulation model fusion, dividing VSP into 10 bins, analyzing the relationship between three emissions and 10 VSP bins, calculating the three vehicle emissions＇ mass emission rate in 10 VSP bins. Conclusion that the light-duty vehicle＇s three emissions closely related with VSP; binl ~ bin3 correspond- ing to deceleration situation, the emission rate is slowest; bin6~binl0 corresponding to relatively high speed and acceler- ation situation, the emission rate is significantly higher; research obtained mass emission rates under different VSP bins can serve as a basis to quantify regional emissions.
