摘要：
A highly effective fuel additive composition for control of intake valve deposits is described. It comprises (a) a gasoline-soluble Mannich reaction product of (i) a high molecular weight alkyl-substituted phenol, (ii) amine, and (iii) aldehyde; (b) a gasoline-soluble poly(oxyalkylene) carbamate; and (c) a gasoline-soluble poly(oxyalkylene) alcohol, glycol or polyol, or mono or diether thereof. Fuel compositions and methods of controlling engine deposits are also described.
