摘　　要：在利用先进的车载尾气检测技术(PEMS)收集了我国大型柴油客车尾气的实时排放数据的基础上,分析了不同排放标准下车辆(国Ⅰ、国Ⅱ、国Ⅲ)的CO、HC、NOx和PM排放因子与速度的关系;使用MOBILE6模型,经过模型参数校正,预测了相应车辆的排放因子,并与不同排放标准下的车辆排放实测值进行对比,从而验证了MOBILE6模型对我国大型柴油客车尾气排放预测的适用性。Real-world emission data of heavy-duty diesel buses under different emission standards were collected by using the portable emission measurement system（PEMS）.The differences among emission factors of CO,HC,NOx and PM under different standards（Phase I,II and III） were compared,and the relationship between emission factors and speed were analyzed.Then,emission factors were derived by MOBILE6 emission factor model through adjusting the input parameters according to the tested buses.Finally,the real-world emission factors under different standards were compared with those predicted from MOBILE6 model,and the applicability of MOBILE6 to the emission estimation of heavy-duty diesel buses in China was analyzed.
