Engine lubricating oil with high quality

Abstract

The invention discloses an engine lubricating oil with high quality. The lubricating oil comprises the following materials, by weight, 50-80 parts of plant oil, 3-8 parts of oleic acid, 1 part of hydrophobic and modified nanoscale silicon oxide, 3-5 parts of benzotriazole, 1-3.5 parts of dimethylaniline, 3-12 parts of polyoxyethylene, 0.5-2 parts of polyaleneglycol, 0.1-1.2 parts of sodium alkyl benzene sulfonate, 1-4 parts of alkylated diphenylamine, 3-5 parts of polymethacrylate, 4-5 parts of sorbic furfuryl alcohol anhydride monooleate and 25-35 parts of No.10 hydrogenated engine oil. The beneficial effects of the lubricating oil are that, the lubricating oil has excellent acid neutralization capability, excellent antiwear performance and anticorrosion performance; compared with conventional lubricating oil, the antiwear performance of the lubricating oil is especially excellent.

Description

technical field [0001] The invention relates to a high-quality lubricating oil for engines. 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.

Problems solved by technology

[0003] Automobiles with engines using natural gas are more and more widely used. The temperature of the combustion chamber of this type of engine is high, and the temperature of the exhaust gas is high. The lubricating oil of the engine is easily oxidized, carbonized, and sludge is formed, which increases the carbon deposit inside the engine. , affecting the normal operation of the engine

In addition, in order to improve the lubricating performance and reduce the viscosity of lubricating oil, many lubricating oils can ensure the good work of the parts in actual work. However, under high temperature conditions, this kind of lubricating oil is volatile, resulting in Lubricants have a shorter lifespan
