Title
(EN) LUBRICATING OIL COMPOSITION
(FR) COMPOSITION D'HUILE LUBRIFIANTE
(JA) 潤滑油組成物
Abstract
(EN)
A lubricating oil composition which contains: at least one base oil that is selected from the group consisting of mineral oil-based lubricating oils, synthetic oil-based lubricating oils and mixed oils of those lubricating oils; a zinc dialkyl dithiophosphate X represented by general formula (1); and an acidic phosphoric acid ester amine salt Y represented by general formula (2). This lubricating oil composition is configured such that: the content PX in the component X is from 0.06% by mass to 0.08% by mass in terms of the phosphorus concentration relative to the total mass of the composition; and the content PY in the component Y is from 0.015% by mass to 0.025% by mass in terms of the phosphorus concentration relative to the total mass of the composition.
(FR)
Composition d'huile lubrifiante qui contient : au moins une huile de base qui est choisie dans le groupe constitué d'huiles lubrifiantes à base d'huile minérale, d'huiles lubrifiantes à base d'huile synthétique et d'huiles mélangées de ces huiles lubrifiantes; un dithiophosphate de dialkyle et de zinc (X) représenté par la formule générale (1); et un sel d'amine acide de l'ester d'acide phosphorique (Y) représenté par la formule générale (2). Cette composition d'huile lubrifiante est configurée de telle sorte: que la teneur PX dans le composant X soit de 0,06 % à 0,08 % en masse en termes de concentration en phosphore par rapport à la masse totale de la composition; et que la teneur en PY dans le composant Y soit de 0,015 % à 0,025 % en masse en termes de concentration en phosphore par rapport à la masse totale de la composition.
