摘　　要：搭建了机动车车载排放测试平台,获取了实际排放数据。对轻型车比功率进行了分区,得到了3种排放污染物的质量排放率。基于OD数据反推,将速度和加速度作为输入参数,采用排放模型和交通仿真模型,计算了城市区域的机动车排放总量与排放比例。计算结果表明:在晚高峰时段,CO、HC、NOx3种排放污染物的小时排放量分别为163.364 7、19.453 9、77.701 8kg;轻型车、中型车和公交车的CO排放比例分别为65.45%、29.57%、4.98%;轻型车、中型车和公交车的HC排放比例分别为57.68%、26.03%、16.29%;轻型车、中型车和公交车的NOx排放比例分别为48.11%、4.63%、47.26%;轻型车和中型车是CO和HC排放控制的重点,而公交车为NOx排放控制的重点。The on-board emission test platform of vehicles was put up, and the actual emission data were obtained. The specific power divisions of light-duty vehicles were carried out, and the quality emission ratios of three emission pollutants were gotten. Based on OD data back-stepping, speed and acceleration were taken as input parameters, and the total emissions and emission ratios of vehicles in urban region were calculated by using emission model and traffic simulation model. Calculation result indicates that during late-peak period, the hour emissions of CO, HC and NOx are 163. 364 7, 19. 453 9 and 77. 701 8 kg respectively. CO emission ratios of light-duty vehicles, middle-duty vehicles and busses are 65. 45%, 29. 57% and 4. 98% respectively. HC emission ratios of light-duty vehicles, middle-duty vehicles and busses are 57.68%, 26.03% and 16.29% respectively. NOx emission ratios of light-duty vehicles, middle-duty vehicles and busses are 48.11%//00, 4.63% and 47.26% respectively. Light-duty and medium-duty vehicles are the emission control emphases of CO and HC, and busses are the emission control emphasis of NOx. 6 tabs, 7 figs, 23 refs.
