| 摘 要： | 在中国典型城市公交循环工况下,采用车载排放测试技术,以纯柴油模式的怠速排放水平作为比较基准,对某一大型混合动力客车发动机的启动/停止(S/S)对排放特性的影响进行了研究.试验结果表明:从排放总量上看,混合动力汽车的HC、CO、NO_x、CO_2和PM的排放量都比纯柴油模式低;而混合动力模式S/S阶段的HC、CO和NO_x的排放量要比纯柴油模式怠速排放量低;但是PM排放量相反,混合动力发动机在启动和停止时都出现排放峰值;从控制PM排放量来说,该混合动力客车停机时间应长于7s.

| Abstract: | Taking the idling emissions in pure diesel engine mode as comparison base,the effects of start /stop(S/S)of a large hybrid electric bus(HEB)engine on its emissions with typical city-bus driving-cycle in china are studied by using portable emission measurement system(PEMS).The results show that viewing from total emission,the emissions of HC,CO,NOx,CO2 and PM of HEB are all lower than that with pure diesel mode;while in(S/S)stage of HEB engine,the emissions of HC,CO and NOx are all lower than that in pure di... |
