Title (EN) ASPHALTENE DISPERSANT CONTAINING LUBRICATING COMPOSITIONS
(FR) COMPOSITIONS LUBRIFIANTES CONTENANT UN DISPERSANT DES ASPHALTÈNES
Abstract: front page image
(EN)The present invention relates to a lubricating composition, particularly marine diesel engine lubricating compositions, comprising: (a) an oil of lubricating viscosity; (b) an asphaltene dispersant comprising a cyclic headgroup that contains a nitrogen atom and at least one other heteroatom; and (c) a detergent derived from an alkyl phenol. The invention further provides methods of using such compositions in the operation of engine, particularly marine diesel engines.
(FR)La présente invention porte sur une composition lubrifiante, en particulier sur des compositions lubrifiantes pour moteurs diesel marins, comprenant : (a) une huile de viscosité lubrifiante ; (b) un dispersant des asphaltènes comprenant un groupe de tête cyclique qui contient un atome d'azote et au moins un autre hétéroatome ; et (c) un détergent issu d'un alkyl phénol. L'invention porte également sur des procédés d'utilisation de ces compositions dans le fonctionnement de moteurs diesel en particulier de moteurs diesel marins.
