摘要
在符合国Ⅰ、国Ⅲ、国Ⅴ标准的3辆试验车上,分别燃用国Ⅴ汽油、低芳烃E10、低烯烃E10 3种燃料,进行了NEDC和WLTC工况下的常温冷起动排放试验,重点对颗粒物(PM)排放量和粒子数量(PN)进行分析。结果表明:在两种工况下,燃用乙醇汽油相比普通汽油能大幅降低车辆的PM排放,低芳烃E10对国Ⅰ和国Ⅲ车辆PM降低效果最明显,分别下降19%和35%,低烯烃E10对国Ⅴ车辆PM降低效果最好,下降46%;在WLTC工况下燃用乙醇汽油能大幅降低车辆PN排放,其中低芳烃E10平均降低43%,低烯烃E10平均降低32%。
Three vehicles fueled with ChinaⅤgasoline,low aromatic E10 and low olefins E10 that met ChinaⅠ,ChinaⅢand ChinaⅤ emission regulation respectively were tested according to the NEDC and WLTC cycles And the particulate matter(PM)and the particle number(PN)were analyzed.The results showed that the ethanol gasoline could reduce PM emission significantly under the two cycles.Compared with ChinaⅤ gasoline,the low aromatics E10 could reduce the PM emission of ChinaⅠand ChinaⅢ vehicle by 19%and 35%respectively and the low olefins E10 could reduce the PM emission of ChinaⅤvehicle by 46%.In addition,ethanol gasoline could reduce the PN emission of WLTC cycle.The average reduction of low aromatics E10 and low olefins E10 was 43% and 32% respectively.
