LUBRICATING OIL COMPOSITION Russian patent published in 2017 - IPC C10M169/04 C10N10/12 C10N20/02 C10N30/02 C10N30/06 C10N40/25 

FIELD: chemistry.

SUBSTANCE: present invention relates to a lubricating oil composition containing: (A) base oil, kinematic viscosity of which at 100 °C varies from 1.4 to 6 mm²/s, (B) from 250 to 2,000 ppm in terms of molybdenum of a molybdenum dialkyldithiocarbamate of formula (1), where R¹-R⁴ denote alkyl groups, and X¹-X⁴ denote oxygen atoms or sulphur atoms, (C) from 20 to 500 ppm in terms of sulphur of tetrabenzyl thiuram disulphide of formula (2) and (D) from 0.05 to 3.0 wt% of amine of formula (3) or formula (4), where R⁵-R⁷ both independently, denote hydrogen or alkyl, aryl or alkyl aryl group having from 1 to 23 carbon atoms, where (4) R⁸ and R⁹ both independently denote hydrogen or alkyl, aryl or alkyl aryl group containing 1 to 23 carbon atoms. Present invention relates to use of lubricating oil composition (versions).

EFFECT: technical result of present invention is minimisation of effect on equipment for treating exhaust gases and catalysts as a result of reduction, as much possible, amounts of contained MoDTC compounds and sulphur compounds thus creating, even in case of presence of latter in trace quantities, a lubricating oil composition, which demonstrates excellent effect on reduction of friction for a long period of time, and which is characterised by high degree of fuel saving.
