Title
(EN) LUBRICATING OIL COMPOSITION FOR INTERNAL COMBUSTION ENGINE
(FR) COMPOSITION D’HUILE LUBRIFIANTE DESTINÉE À UN MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関用潤滑油組成物
Abstract
(EN)
The purpose of the present invention is to provide an engine oil composition which is unlikely to undergo degradation of an organic molybdenum compound after long term use and which can maintain lubricity even if a base oil having a low aromatic component content is used and a large quantity of an antioxidant or a zinc dithiophosphate compound is not contained therein. In order to achieve the foregoing, the present invention provides a lubricating oil composition for an internal combustion engine, which contains: a base oil that is a hydrocarbon oil having an aromatic component content of less than 1 mass% and a sulfur content of less than 20 ppm by mass; a specific organic molybdenum compound as component (A) at a quantity of 300-1500 ppm by mass in terms of molybdenum atoms; and a boric acid ester compound as component (B) at a quantity of 100-1000 ppm by mass in terms of boron atoms.

La présente invention concerne une composition d’huile pour moteur qui n’est pas susceptible de subir la dégradation d’un composé molybdène organique après une utilisation à long terme et qui peut conserver sa lubricité même si une huile de base ayant une teneur en constituants aromatiques inférieurs est utilisée et qu’une grande quantité d’un antioxydant ou d’un composé dithiophosphate de zinc n’y est pas contenu. Afin d’atteindre ce qui précède, la présente invention décrit une composition d’huile lubrifiante destinée à un moteur à combustion interne, qui contient : une huile de base qui est une huile hydrocarbure ayant une teneur en constituants aromatiques inférieurs à 1 % en masse et une teneur en soufre inférieure en 20 ppm en masse ; un composé molybdène organique spécifique comme constituant (A) sous une quantité de 300 à 1 500 ppm en masse en termes d’atomes de molybdène ; et un composé ester d’acide borique comme constituant (B) sous une quantité de 100 à 1 000 ppm en masse en termes d’atomes de bore.
