AI Technical Summary

Problems solved by technology

As a result, it was found that the efficiency of fuel consumption deteriorated due to the deterioration of the friction performance at medium and high temperatures, which was considered to be important due to the recent increase in heat load, and the friction performance in the wet clutch was also extremely deteriorated.
It has also been found that the efficiency of low fuel consumption at high temperatures in the aforementioned conventional engine lubricating oils is also unsatisfactory

Abstract

The invention discloses a lubricating oil composition production method. The composition comprises minerals and / or synthetic base-stocks, an organic molybdenum compound (A) with the content being 0.003%-0.1% by mass on the basis of molybdenum, boron-containing and / or boron-free succinimide (B) with the content being 0.08%-0.3% by mass on the basis of nitrogen, an alkaline earth cleaning agent (C)with the content being 0.01%-0.16% by mass on the basis of alkaline earth, zinc dithiophosphate (D) with the content being 0.01%-0.1% by mass on the basis of zinc and at least one compound (E) selected from phosphate ester, phosphite ester and salt, wherein the mass ratio of nitrogen to molybdenum of the component (A) is 1.6 or larger, the content of the compound (E) is 0.1% by mass on the basis of phosphorus, the contents are based on the total weight of the compound, and the content of sulfated ash is 1% or lower by mass on the basis of the total weight. The compound has the excellent fuel consumption performance from the middle temperature to the high temperature, the static friction performance is achieved, and the accelerated reaction indexes of starting and shifting are improved.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a production method of the lubricating oil composition. Background technique [0002] In recent years, the reduction of CO2 is now strongly required from the viewpoint of global environmental protection, and therefore efforts have been made in the development of technologies for saving fuel consumption in the automotive field. Such mainstream technologies for saving fuel consumption include hybrid vehicles and electric vehicles, and it is expected that they will spread rapidly in the future. Hybrid vehicles and electric vehicles are characterized by having electric motors and generators, some or all of which are driven by electric motors. In hybrid vehicles and electric vehicles, if the electric motor is cooled by oil cooling, conventional automatic transmission oil or continuously variable transmission oil is mainly used as a lubricating oil composition. In order to give these ...
