Abstract | A method for improving wear control, while maintaining or improving fuel efficiency, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and (i) at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) or (ii) a mixture of at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) and at least one detergent (i.e., an alkali metal or alkaline earth metal salt of an organic acid, or an alkali metal or alkaline earth metal salt of an inorganic acid, or an alkali metal or alkaline earth metal salt of a phenol, or mixtures thereof (e.g., calcium salicylate and/or magnesium sulfonate), as a minor component. The lubricating oils are useful in internal combustion engines.
L'invention concerne un procédé permettant de mieux lutter contre l'usure, tout en maintenant ou en améliorant le rendement du carburant, dans un moteur ou autre élément mécanique lubrifié avec une huile lubrifiante par le biais de l'utilisation d'une huile formulée en tant qu'huile lubrifiante. L'huile formulée a une composition comprenant une matière de base d'huile lubrifiante en tant que constituant principal, et (i) au moins un sel de métal de transition d'un acide carboxylique (par exemple, le stéarate de zinc) ou (ii) un mélange d'au moins un sel de métal de transition d'un acide carboxylique (par exemple, le stéarate de zinc) et au moins un détergent (c'est-à-dire, un sel de métal alcalin ou de métal alcalino-terreux d'un acide organique, ou un sel de métal alcalin ou de métal alcalino-terreux d'un acide inorganique, ou un sel de métal alcalin ou de métal alcalino-terreux d'un phénol, ou leurs mélanges (par exemple, du salicylate de calcium et/ou du sulfonate de magnésium), en tant que constituant mineur. Les huiles lubrifiantes sont utiles dans des moteurs à combustion interne. |
