| 摘 要： | 以93#国Ⅲ乙醇汽油(E10)、93#国Ⅲ普通汽油和93#国Ⅳ普通汽油为实验对象,对GB18352.3-2005中要求限定的CO、HC和NOx,以及颗粒物(PM)和CO2等主要污染物的排放进行了测量和对比研究,并对CO、HC、PM、NOx、CO2和苯系物等污染物的形成原因和减排机理进行了分析。和93#国Ⅲ普通汽油相比,93#国Ⅲ乙醇汽油(E10)排放的尾气中:CO降低了19.7%,HC降低了16.4%;和93#国Ⅳ普通汽油相比,93#国Ⅲ乙醇汽油(E10)排放的尾气中:CO降低了1.8%,HC降低了12.9%, CO2降低了2.4%。研究表明,乙醇汽油在减少CO、HC、NOx、颗粒物和苯系物等有毒物质排放方面具有显著功效,使用乙醇汽油可以减少环境污染物的排放,显著改善空气质量。

| Abstract: | No.93 ethanol gasoline(E10) (Nation Ⅲ standard) and No.93 regular gasoline(Nation Ⅲ and Nation Ⅳ standard) were used as vehicle fuel to detect pollutants emission. The emission of CO, HC and NOx which were limited in GB18352.3-2005 as well as main pollutants particular matter(PM) and CO2 were detected. The formation and reduction mechanism of CO, HC, PM, NOx, CO2 and toxic substance such as benzene series were discussed and analyzed. Compared with regular gasoline(Nation Ⅲ standard), the CO and HC emission of ethanol gasoline(E10) greatly decreased by 19.7% and 16.4%, respectively. Compared with regular gasoline(Nation Ⅳ standard), the CO, HC and CO2 emission of ethanol gasoline(E10) decreased by 1.8%, 12.9% and 2.4%, respectively. The results show that ethanol gasoline can play a positive role in decreasing pollutants emission and improving air quality. |
