摘　　要：以公交车为例,利用OBS-2200和ELPI(electrical low pressure impactor)对深圳市重型柴油车(high-duty dieselvehicles,HDDVs)进行了3次在实际道路上的车载排放测试。根据测试数据计算了NOx和PM排放因子及百公里油耗,并分析了不同道路、不同工况对NOx和PM排放及燃油消耗的影响。研究表明,深圳市快速道上交通状况良好,有效地降低了排放;次干道上NOx和PM排放因子分别为16.85 g/km和3.24 g/km,比其他道路要高;加速工况是排放最恶劣、耗油最多的工况,NOx和PM质量排放率分别为137.50 mg/s和37.65 mg/s,燃油消耗率为15.15 L/h;车辆在高速状态下加速时的NOx和PM排放比车辆启动时要高。Taking bus as an example,three on-road vehicle emission tests of high-duty diesel vehicles（HDDVs） were conducted using OBS-2200 and ELPI（electrical low pressure impactor） in Shenzhen city.The emission factors of NOx and PM,fuel consumption were calculated accurately,furthermore,the impacts of different roads and different driving patterns on emissions of NOx and PM,fuel consumption were analyzed.The results show that the traffic condition on highway in Shenzhen city is good so that the emissions are effectively reduced.The emission factors of NOx and PM on sub-road are 16.85 g/km and 3.24 g/km,respectively,higher than the other roads.The acceleration pattern causes higher emissions and fuel consumption than the other driving patterns,the mass emission rate of NOx and PM are 137.50 mg/s and 37.65 mg/s,respectively,the fuel consumption rate is 15.15 L/h.The emissions of NOx and PM are higher when the vehicle accelerates at high speed than those when the vehicle starts.
