| 摘 要： | 选择5台国六直喷汽油车采用3种不同组分的E10乙醇汽油和1种不含含氧化合物的国VI汽油，按照国六排放标准开展了WLTC循环测试，研究乙醇和基础油组分对污染物排放的影响规律.结果表明，多数国六直喷汽油车的CO、THC和PM排放有所降低，NOx排放无明显差异，PN排放微增，所有样车的CO、THC和PM平均排放降低为6%、7%和14%.E10乙醇汽油中的重质芳香烃含量增高时，PN排放明显增加，PN排放与PMI指数呈现较强的正相关关系.

| Abstract: | To determine the effects of ethanol and fuel components on the exhaust emissions, five China-6 compliant GDI vehicles fueled with three E10 ethanol-gasoline with different compositions and one non-oxygenated China-6 gasoline were tested over the WLTC. The results indicated that burning E10 reduced CO by 6%, THC by 7%, and PM by 14%, but caused a slight increase in PN with mostly equal NOx. When the contents of heavy aromatic hydrocarbons in E10 ethanol-gasoline increased, PN emissions increased markedly, PN emissions also showed a strong positive correlation with the PMI index. |
