A composition and method of improving the fuel economy of hydrocarbon fuel- powdered internal combustion engines. The composition contains a propoxylated and/or butoxylated reaction product of (a) at least one fatty acid, fatty acid ester, or mixture thereof and (b) a dialkanolamime. The composition is added to a hydrocarbon fuel in an amount of about 5 to about 2,000 ppm, based on the weight of the hydrocarbon fuel, to reduce friction within the engine and achieve an enhanced fuel economy.

L'invention porte sur une composition et un procédé pour améliorer l'économie en combustible de moteurs à combustion interne alimentés par des combustibles hydrocarbonés. La composition contient un produit de réaction propoxylé et/ou butoxylé de (a) au moins un acide gras, un ester d'acide gras ou un mélange de ceux-ci et (b) une dialcanolamine. La composition est ajoutée à un combustible hydrocarboné dans une quantité d'environ 5 à environ 2 000 ppm, sur la base du poids du combustible hydrocarboné, pour réduire le frottement à l'intérieur du moteur et parvenir à une économie en combustible améliorée.
