汽油质量标准对污染物排放标准的影响

Analysis on the Effect of Gasoline Quality Standard on Pollutant Emission Standard

分析了欧Ⅲ、欧Ⅳ和国Ⅲ、国Ⅳ轻型汽车尾气排放标准及与其相对应的汽油质量标准,并进行了比较,阐述了汽油中硫、苯、烯烃、芳烃和氧含量及其抗爆性能对污染物排放的影响,指出进一步降低硫、烯烃、芳烃等的含量是提高汽油抗爆性,降低汽车尾气污染物排放的关键,新的排放标准的实施对保护环境有积极意义。

The quality of oil product is the important factors affecting vehicle exhaust emissions,the reduction of the contents of sulfur,olefin,metals etc.can decrease all the kinds of pollutant emissions in vehicle exhaust.Therefore,in order to meet the requirements of national automobile emission standards,the standard of gasoline quality should be increased in advance.
