| 摘 要： | 在重型底盘测功机上,测量了混合动力客车(HEB)在中国典型城市公交循环(CCBC)和全球商用车瞬态循环(WTVC)下的油耗排放,对比分析了HEB在两个循环中燃油经济性、排放因子,以及不同工况气态污染物分担率。结果表明,WTVC下HEB的燃油经济性好于CCBC下的燃油经济性;而HEB的排放比CCBC恶劣,THC和NOx的里程排放因子分别是CCBC下的2.1倍、1.9倍;加速工况气态污染物分担率最高,怠速工况最低。加速工况THC和NOx的分担率分别是怠速工况、减速工况以及匀速工况的2.2~2.7倍、1.7倍和1.5倍,加速工况CO分担率更是高达70%,由于HEB采用减速时发动机迅速减油的控制策略,因此减速工况气态污染物分担率比匀速工况低。

| Abstract: | A hybrid electric bus(HEB) was tested on heavy-duty chassis dynamometer to explore its energy consumption and emissions under two different cycles,chinese city bus cycle(CCBC) and world transient vehicle cycle(WTVC),respectively.Fuel economy and emission factors of HEB were compared in two cycles,and gas pollutants contribution rates under different working condition were investigated.The results show that,fuel economy of HEB under WTVC was better than that under CCBC while emissions of pollutants were wors... |
