Title (EN) MARINE DIESEL LUBRICANT OIL COMPOSITIONS HAVING IMPROVED LOW TEMPERATURE PERFORMANCE
(FR) COMPOSITIONS D'HUILE LUBRIFIANTE DIESEL MARINE POSSÉDANT DES PERFORMANCES AMÉLIORÉES À BASSE TEMPÉRATURE
Abstract:
(EN) A method for improving low temperature performance of a lubricant in a compression-ignited internal combustion engine is disclosed. The method comprises operating the engine with a monograde lubricating oil composition comprising (a) a major amount of a base oil of lubricating viscosity; and (b) a minor amount of an overbased alkaline earth metal salt of an alkyl-substituted hydroxyaromatic compound, the alkyl substituent being a residue derived from an isomerized alpha-olefin having from 12 to 40 carbon atoms per molecule.
(FR) L'invention concerne un procédé pour améliorer les performances à basse température d'un lubrifiant dans un moteur à combustion interne à allumage par compression. Le procédé consiste à faire fonctionner le moteur avec une composition d'huile lubrifiante monograde comprenant (a) une quantité majeure d'une huile de base de viscosité lubrifiante ; et (b) une quantité mineure d'un sel de métal alcalino-terreux surbasé d'un composé hydroxyaromatique à substitution alkyle, le substituant alkyle étant un résidu dérivé d'une alpha-oléfine isomérisée dotée de 12 à 40 atomes de carbone par molécule.
