摘　　要：为了研究国Ⅵ标准下不同类型混合动力汽车在实际道路中的排放特性,作用采用便携式排放测试系统(PEMS)对3辆轻型混合动力汽车和1辆汽油车进行了实际道路行驶排放测试(RDE)。结果发现:混合动力汽车(增强式混合动力汽车REEV、插电式混合动力汽车PHEV、油电混合动力汽车HEV)在各类道路上的CO_(2)排放均低于轻型汽油车(LDGV)。其中,相较于混合动力汽车,LDGV的CO_(2)排放因子高出1.01~2.09倍。此外,测试还揭示了汽车CO_(2)排放速率与车速、加速度间存在显著的多项式关系。尤为值得注意的是,在多数工况下,REEV和PHEV的CO和NO_(x)排放量均低于LDGV和HEV,特别是在电力驱动模式下,它们几乎不产生NO_(x)排放,充分展现了其在减少排放方面的显著优势。研究结果对于推动绿色出行、优化交通管理策略具有重要意义。To investigate the emission characteristics of different types of hybrid vehicles under ChinaⅥstandards on actual roads,a portable emission measurement system(PEMS)was used in Kunming to conduct real driving emission tests on three hybrid vehicles and one gasoline vehicle.The results showed that CO_(2) emissions of hybrid vehicles(REEV,PHEV,HEV)on various road types were lower than those of light-duty gasoline vehicle(LDGV).Specifically,the CO_(2) emission factors of LDGV were 1.01 to 2.09 times higher than those of hybrid vehicles.Furthermore,the tests also revealed a significant polynomial relationship between CO_(2) emission rates of vehicles and factors such as vehicle speed and acceleration.Notably,under most driving conditions,the CO and NO_(x) emissions of REEV and PHEV were lower than those of LDGV and HEV,especially during electric-only driving,where almost no NOx emissions were produced,demonstrating their significant advantages in reducing emissions.These findings are of great significance for promoting green transportation and optimizing traffic management strategies.
