| 摘 要： | 我国的机动车温室气体排放研究多集中于CO2排放,而CH4和N2O排放的相关研究主要是依据欧美开发的模型进行的,缺乏CH4和N2O实车测试的研究.本研究选取22辆轻型汽油车,利用底盘测功机开展了整车台架测试和采样分析,获得了车辆在NEDC工况下的CH4和N2O排放因子.结果表明,国Ⅰ~国Ⅳ阶段轻型汽油车CH4平均排放因子分别为0.048、0.048、0.038和0.028 g·km-1,N2O则分别为0.045、0.039、0.026和0.021 g·km-1.在轻型汽油车单车排放的CO2、CH4和N2O三类温室气体(以CO2当量计)中,CH4和N2O排放的分担率均随排放标准的加严而逐渐降低,其中CH4排放在温室气体排放中不足0.5%,N2O排放分担率在3.03%~6.35%之间.因此,排放标准的加严可以有效减少CH4和N2O的排放,以减缓机动车排放带来的温室效应.
