TITANIUM-CONTAINING LUBRICATING OIL COMPOSITION Russian patent published in 2012 - IPC C10M163/00 C10M129/26 C10M133/16 C10M159/20 C10N10/08 C10N30/04 C10N40/25

Abstract RU 2451721 C2

FIELD: chemistry.

SUBSTANCE: disclosed composition can be used to lubricate vehicle components. The composition contains at least one succinimide dispersant, a polyalkylene derivative with about 50-85% vinylidene double bonds, as well as a metal-containing detergent, at least one antiwear agent, at least one antioxidant and a hydrocarbon-soluble titanium component. The titanium compound is a product of reaction of titanium alkoxide with C₆-C₂₅ carboxylic acid. Described also is a lubricated surface, a method of reducing deposits in an internal combustion engine and a lubricant additive concentrate.

EFFECT: reduced formation of carbon deposits.
