| 中文摘要 | 通过一辆轻型汽油车分别燃用纯汽油、E10、E20燃料,在轻型车底盘测功机上进行了NEDC工况的排放测试。汽车尾气中主要污染物的瞬态排放和循环工况平均排放测量结果的对比,验证了MEXA、FTIR、HPLC、GCMS等各种测试方法具有较好的一致性。在冷起动第1个汽车加速工况时,乙醛、甲苯、丙烯、1,3-丁二烯瞬态排放会有最高峰值,而在催化剂起燃后逐渐降低到零排放附近,并维持到NEDC工况结束。随着燃料中乙醇比例的增加,尾气排放中的乙醛增加,HC、CO、CH4、苯、甲苯、二甲苯、乙烯、丙烯、1,3-丁二烯和异丁烯减少,而CO2、NOx甲醛和丙酮基本不变。; An emission test is carried out on a chassis dynamometer for a light-duty vehicle fuelled with pure gasoline and ethanol gasoline E10 and E20 with NEDC cycle.The comparison between transient emissions and average emissions in a driving cycle of major pollutants verifies the good consistency of different measuring methods including MEXA,FTIR,HPLC and GC-MS.The transient emissions of acetaldehyde,toluene,propylene and 1,3-butadiene during the first acceleration condition after cold start have the highest peaks and then with catalyst light off,the emissions levels gradually lower to nearly zero and remain until the end of driving cycle.As the ethanol proportion in the fuel increases,acetaldehyde in tail gas rises,HC,CO,CH4,benzene,toluene,xylene,ethylene,propylene,1,3-butadiene and isobutene decrease,while CO2,NOx,acetone and formaldehyde remain basically unchanged. |
