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
