Problems solved by technology

However, it is difficult for nanoparticles to disperse uniformly and exist stably for a long time in the engine oil system. In the prior art, sulfur and phosphorus organic compounds are used to modify nanoparticles. Although the dispersion can be improved, too much S and P will affect the environment. cause harm

Abstract

The invention provides a gasoline engine oil composition. The gasoline engine oil composition has the SAE viscosity grade of 0W-40 and is prepared from, by weight, 5.0% to 20.0% of ester compounds, 0.1% to 5.0% of diphenylamine derivatives, 0.01% to 2.0% of modified nanometer cerium vanadium acid, 1.0% to 8.0% of petroleum calcium sulfonate, 0.001% to 1.0% of common gasoline engine oil additives and the balance base oil. The API quality of the gasoline engine oil composition reaches the SN grade, abrasion resistance is good, friction between engine parts can be effectively reduced, the mileage of gasoline can be increased, the durability of gasoline can be improved, and it is guaranteed that the acme performance of an engine is achieved.

Description

technical field [0001] The invention relates to a gasoline engine oil composition, in particular to a multi-grade engine oil for gasoline engines. Specifically, the International Patent Classification number C10M is involved. Background technique [0002] In the heat generated by fuel combustion in gasoline engines, about 20-30% of the energy is wasted in the form of friction, and the part with the largest friction loss is between the contact surface of the piston cylinder liner / piston ring. The use of engine oil can effectively Reduce friction loss. With the continuous development of the gasoline engine manufacturing process, the engine parts with increasing precision have higher and higher requirements for engine oil. Nanoparticles are often added into engine oil as a friction modifier / extrusion anti-wear agent. They will form an easy-to-shear lubricating film on the surface of the friction pair, and at the same time fill and repair the worn metal surface, effectively ...
