Abstract: Due to the need for vehicle energy saving and emission reduction in the city, the HEVs with low displacement and different dynamic systems were studied and simulated. The simulation and analysis results based on ADVISOR indicated that parallel HEV with low displacement could achieve outstanding dynamics, economy performance and emission property as well. According to the characters of the city-drive-mode, the parallel HEV with low displacement was much more suitable for automobile energy saving, emissions reduction and environment protection than that of the series HEV.

Key words: hybrid electric vehicle(HEV ), dynamic system, emission, simulation and analysis

摘要： 从城市汽车节能减排的角度,以不同动力系统的低排量混合动力汽车为对象,用ADVISOR软件进行仿真分 析,证明小排量的并联式混合动力汽车同时具备良好的动力性、经济性和排放特性。结合城市行驶工况特点,得出 小排量并联混合动力汽车比串联混合动力汽车更适合城市汽车节能减排、环境保护要求的结论。
