Abstract

A special lubricating oil for internal combustion engines is prepared from, by weight, 20-30 parts of base oil, 3-9 parts of sodium citrate, 7-9 parts of p-methoxystyrene, 5-10 parts of maleic acid, 2-6 parts of zinc butyloctyl sulfate, 4-8 parts of trichloromethane, 1-4 parts of an antioxidant, 3-9 parts of ammonium persulfate, 7-9 parts of butyloctyldiphenyl amine, 6-10 parts of polyisobutylene succimide, 2-6 parts of 3,4-methylenedioxyphenol, 7-9 parts of itaconic acid, 4-6 parts of jojoba oil and 1-4 parts of n-butanol. The special lubricating oil for internal combustion engines has the advantages of very good cleaning property, dust removal, and good compression and high temperature resistance.

Description

technical field [0001] The invention relates to a special 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 prior...
