    Abstract: The present invention is directed to a fuel additive composition containing (i) a polyether alcohol of the formula ##STR1## wherein R is hydrogen or a hydrocarbyl group of 1 to about 30 carbon atoms; R.sup.1 is hydrogen or a hydrocarbyl group of 1 to 5 carbon atoms or mixtures thereof provided that no more than 10 mole % of R.sup.1 is hydrogen and where the polyether alcohol is soluble in gasoline; and x is a number from about 4 to about 40; (ii) a hydrocarbylphenol having 1-3 hydrocarbyl groups such that the total weight average molecular weight of the hydrocarbyl groups is about 250 to about 6000; and (iii) optionally a third component containing a nitrogen-containing dispersant; wherein the weight ratio of the polyether alcohol to the hydrocarbylphenol is about 3:1 to about 1:20. The compositions are useful in reducing intake valve deposit and do not contribute to the increase in combustion chamber deposit in port fuel injected engines.

    Abstract translation: 本发明涉及一种燃料添加剂组合物,其包含(i)式(I)的聚醚醇,其中R是氢或1至约30个碳原子的烃基; R1是氢或1至5个碳原子的烃基或其混合物,条件是不超过10摩尔%的R 1是氢,并且其中聚醚醇可溶于汽油; x为约4至约40的数; (ii)具有1-3个烃基的烃基苯酚,使得烃基的总重均分子量为约250至约6000; 和(iii)任选地含有含氮分散剂的第三组分; 其中聚醚醇与烃基苯酚的重量比为约3:1至约1:20。 该组合物可用于减少进气阀沉积物,并且不会有助于燃料喷射发动机端口中燃烧室沉积物的增加。
