Abstract

Composition d'huile lubrifiante améliorée destinée à des systèmes de transmission et des moteurs thermiques d'automobiles, constituée d'une huile possédant une viscosité permettant la lubrification, dans laquelle on a ajouté et mélangé une faible quantité d'une composition d'agents modifiant le frottement qui réduit le coefficient de frottement entre des en pièces mécaniques en mouvement et produit une économie de carburant plus importante. La composition d'agents modifiant le frottement comprend un mélange d'une amine hydrocarbyle alcoxylée et d'un ester partiel de polyol d'un acide gras saturé ou non saturé ou un mélange de ces esters, chacun de ces éléments étant préférablement présent dans une proportion comprise entre environ 0,1 et environ 1,0 % en poids sur la base du poids de l'huile. Cette association de constituants produit plus particulièrement des effets synergiques sur l'économie de carburant lorsqu'on les utilise comme composants dans des lubrifiants de carters-moteurs d'automobiles contenant également des additifs classiques; ces effets n'apparaissant pas avec de l'huile ne renfermant qu'un seul de ces composants.
