摘要: 为了探讨新型多效燃油添加剂(代号MAZ)对车用汽油机燃烧和排放特性的影响,文中介绍了燃油添加剂的功用和基本工作原理,并在汽油机试验台架上,进行了一系列燃油中添加剂在等同工况下的外特性试验和负荷特性试验.试验结果表明,燃油添加剂MAZ能有效改善汽油机的燃烧过程,排气中CO,HC的排放分别减少l1.6%~19.6% 和22 9%~25.2%.

Abstract:

In order to investigate the influence of a new multi.effect fuel additive(code-named MAZ)on the com.bustion and exhaust property of gasoline engine,the function and basic working principle of fuel additives were introduced,and under the same work conditions,a series of ful1.1oad and part-load experiments were performed on an engine test-bench using gasoline with or without the addition of MAZ.Experimental results indicate that the addition of MAZ effectively improves the combustion process of gasoline engine,and the exhausts of CO and HC respectively decrease by 22.9%to 25.2%.11.6% to 19.6% .

Key words: gasoline engine, fuel additive, combustion, exhaust
