摘要：文章简述了汽油添加剂的种类和基本工作原理,在汽油机试验台架上,进行了一系列汽油中含有不同浓度的MAZ添加剂在等同工况下的热车怠速、常用转速为2800r/min的负荷特性和外特性对比试验,探讨新型多效燃油添加剂MAZ加到国产90#汽油中的体积浓度对其节油和排气净化效果的影响。检测结果表明,汽油中含MAZ添加剂的体积分数为0.1%时,能有效改善发动机的燃油经济性和排放特性,而发动机的动力性则基本不变,其综合使用效果较佳。

Abstract: The category and work principle
of gasoline additives are introduced in this paper.With different concentration
MAZ additive,a series of comparison experiments with hot idle speed,load
characteristic under the rotational speed of 2800r/min and external characteristic
at the same operating mode were implemented on a gasoline engine bench.Effects
of the volume concentration of new multifunctional additive,MAZ on fuel-saving
and exhaust purification are discussed.The results show that the fuel economy
and exhaust characteristic of the engine is improved,and power almost does not
change with a better effect,when the volume fraction of gasoline is 0.1%.
Keywords: Gasoline Engine;Additive
