A fuel composition and method for reducing friction or wear and improving fuel economy in an engine. The fuel composition includes gasoline and from about 10 to about 750 ppm by weight based on a total weight of the fuel composition of a hydroxyalkyl hydrocarbyl-substituted succinimide compound having at least two hydroxyl groups attached to a tertiary nitrogen atom of a polyamino group through a hydrocarbyl link, wherein the hydroxyalkyl hydrocarbyl-substituted succinimide is devoid of primary and secondary amino groups.
一种燃料组合物和方法,用于减少发动机的摩擦或磨损并提高燃油经济性。该燃料组合物包括汽油和按燃料组合物总重量计算的约 10 至约 750 ppm 的羟烷基烃基取代的琥珀酰亚胺化合物(按重量计),该化合物具有至少两个羟基,通过烃基键连接到聚氨基的叔氮原子上,其中羟烷基烃基取代的琥珀酰亚胺不含伯氨基和仲氨基。
