Anti-Burn Engine Oil and Preparation Method Thereof

Abstract

Provide is an anti-burn engine oil, which comprises a base oil, and copper powder or ceramic powder having the particle diameter of 110 nm-300 nm and the aspect ratio of no greater than 3:1, wherein the amount of copper powder or ceramic powder is 25 g-100 g in per liter the base oil. The copper powder or ceramic powder contained in the engine oil can increase the potential energy of the towed particles in the cylinder and form a variety of complex movements under the relative movement of friction pair so as to not only greatly reduce the dry friction, but also have a good lubricating property and avoid the engine oil burning. At the same time, particles in motion possess the specialty of decreasing the temperature of the oil film, increasing the anti-oxidation ability of the engine oil, prolong the service life of the engine oil, and enhance the maintenance of the engine.
