Description

technical field

[0001] The invention provides a lubricating oil, in particular to a highly anti-wear engine lubricating oil, which belongs to the technical field of lubricating oil. Background technique

[0002] During the working process of the engine, a large number of parts are adjusted and operated. These moving parts form many friction pairs, and proper lubrication is required between the friction pairs to reduce friction loss. Engine lubricating oil has the functions of lubrication, cooling, cleaning, shock absorption, sealing and antirust, and requires proper viscosity, high temperature resistance, oxidation resistance and good thermal stability. In addition, it should also have good lubricity, certain extreme pressure and clean dispersion. It is required to have good corrosion resistance, anti-foaming properties, and the ability to neutralize acidic substances.

[0003] Automobiles with engines using natural gas are more and more widely used. The temperature of th...
