Abstract

Disclosed is cleaning type internal combustion engine lubricating oil. The cleaning type internal combustion engine lubricating oil comprises, by weight, 6-14 parts of lupeol palmitate, 3-7 parts of antioxidant, 4-9 parts of monopotassium phosphate, 4-6 parts of bisphenol A polycarbonate, 3-5 parts of citric acid mono-methyl ester, 2-6 parts of dodecanedioic acid, 7-11 parts of epoxy acrylic acid, 20-30 parts of base oil, 1-4 parts of amino phosphate, 3-10 parts of sorbitan monooleate, 2-6 parts of glycerinum monooleate, 7-11 parts of dimethyl phthalate, 2-6 parts of walnut oil and 1-2 parts of nanometer hafnium carbide powder. The cleaning type internal combustion engine lubricating oil has the advantages that the cleaning performance is excellent, accumulated carbon can be excellently cleaned, and meanwhile, certain sealing effect is achieved.

Description

technical field [0001] The invention relates to a cleaning lubricating oil for internal combustion engines. Background technique [0002] Lubricating oil for internal combustion engines is mainly used in the motor vehicle industry. The lubricating oil for internal combustion engines can form a lubricating film between the two friction surfaces, and the dry friction becomes the friction between lubricating oil molecules, so as to reduce the friction of moving parts and reduce wear. It has good oiliness and is widely used in friction reduction, rust prevention and cooling of friction parts of various gasoline engines and diesel engines. At the same time, it also has the functions of sealing, cleaning and lubricating surface impurities. However, the existing lubricating oil has poor cleaning performance and insufficient extreme pressure resistance, which reduces the service life of the lubricating oil. Contents of the invention [0003] Aiming at the deficiencies of the prio...
