摘　　要：随着领先国家的地方油品标准的出台,车辆燃用不同标号的汽油成为可能。用六台不同型号的整车分别燃用不同标号的汽油,研究其排放性能与燃油经济性的影响。试验结果表明:适当降低汽油辛烷值,对燃油经济性的影响效果不明显,最高增幅在2%和4%以内,油耗成本不增加;适当降低辛烷值导致着火延后期短,HC、CO和NO_x整体排放较为明显的降低,最小降幅分别是4.5%,3.5%和4.5%。With the local fuel standards published,which keep ahead of country fuel standards, it becomes possible that vehicles use different grade gasolines. In order to research the effects of emission performance and fuel economy, the project choose six different types vehicles using different grade gasolines to test. The results showed that： It had no obvious effects on fuel economy that vehicles used fuels with appropriate slightly low gasoline octane number, the highest increase within 2% and 4% on fuel consumption and fuel economy costs was not increased; appropriate to reduce the octane number which leaded to Ignition delay period becoming shot , so HC, CO and NO、 emission obviously reduced, the minimum drop was respectively 4.5%, 3.5% and 4.5%.
