燃油品质对于机动车尾气污染物排放量的影响分析

摘要

车辆燃油品质对于尾气污染物排放有直接关系,根据现有的国内外已发表的相关实验结果,总结分析了不同燃油标准对于尾气污染物排放的影响,并在四川省2014年机动车排放清单的基础上,计算比较了使用不同国标燃油时对尾气污染物排放的影响.结果表明,当油品从国Ⅳ提升至国V时,全省SO2削减比例为79.9％,NOX削减比例为0.97％,CO削减比例为9.04％,PM10削减比例为0.97％,PM2.5削减比例为0.97％,VOC削减比例为2.24％.%Vehicle fuel quality is directly related to exhaust emissions.According to reported experimental results in China and abroad,in this paper,the influence of various fuel parameters on exhaust emissions was summarized and analyzed.Based on the motor vehicle emission inventory in 2014 of Sichuan Province,cacuahed and compared the influence of using different national standards fuel on pollutant emissions.The results showed that when the fuel standard raised from GB IV to GB V,in Sichuan Province,the reduction ratio of SO2,NOx,CO,PM10,and VOC emissions were 79.9％,0.97％,9.04％,0.97％,0.97％,and 2.24％,respectively.
