摘　　要：传统的实验室测试法不能完全反映车辆实际道路排放情况,故此采用车载排放测试的方法来研究实际道路行驶时机动车的排放.通过OBS系统测试18 m公交车的行驶工况,分析该公交车的实际道路排放因子.根据试验结果分析在怠速、减速、匀速和加速等工况下各排放物平均质量排放率的分布情况.The traditional laboratory vehicle emission evaluation method is incapable to reflect the real-road emission perfectly, so on-board emission test method was used to research real-road vehicle emissions. OBS system was applied to research the drive cycle and real-road vehicle emissions of 18-meter-long bus. Then the distribution of average mass emissions was analysed at various drive cycles which include idling cycle, decelerating cycle, advancing evenly and accelerating cycle.
