Title (EN) LUBRICATING COMPOSITION COMPRISING A DIESTER
(FR) COMPOSITION LUBRIFIANTE COMPRENANT UN DIESTER
Abstract:
(EN) The present invention relates to the field of lubricating compositions for motor vehicles. The lubricating composition according to the invention is graded according to the SAE J300 classification defined by the formula (X)W(Y), wherein X represents 0 or 5; and Y represents an integer between 4 and 20; and comprises at least one diester of formula (I): Ra-C(O)-O-([C(R)2]n-O)s-C(O)-Rb. The invention also relates to the use of such a composition as an engine lubricant, in particular for a vehicle engine, in order to reduce the fuel consumption of the engine and to improve engine cleanliness.
(FR) La présente invention concerne le domaine des compositions lubrifiantes pour véhicules à moteur. La composition lubrifiante selon l'invention est de grade selon la classification SAEJ300 défini par la formule (X)W(Y), dans laquelle X représente 0 ou 5; et Y représente un nombre entier allant de 4 à 20; et comprend au moins un diester de formule (I): Ra-C(O)-O-([C(R)2]n-O)s-C(O)-Rb. L'invention concerne également l'utilisation d'une telle composition comme lubrifiant d'un moteur, en particulier d'un moteur de véhicule, pour réduire la consommation de carburant du moteur et pour améliorer la propreté moteur.
