Clean lubricant for gasoline and diesel direct injection engine and preparation method thereof

Abstract

The invention discloses a clean lubricant for a gasoline and diesel direct injection engine. The clean lubricant comprises the following raw materials in parts by weight: 60-80 parts of polyether amine, 20-30 parts of soybean oleic acid, 1-2 parts of alkenyl succinate and 10-20 parts of D100 solvent oil. The polyether amine has a dissolving effect on deposited carbon, particularly has very high dissolving capacity on the deposited carbon in a low-temperature area at the front end of an engine, and the deposited carbon burns away along with oil after being dissolved; the soybean oleic acid canform a layer of adsorption film on the metal surface, the lubricating capacity of the film is very high, and after the lubricating performance is improved, abrasion of a gasoline injection system is reduced, and shaking of an engine can also be reduced. The alkenyl succinate is an antirust agent of an oil product and can inhibit rusting of an oil path system; and the D100 solvent oil is high in flash point, is not inflammable after being blended with the polyether amine, soybean oleic acid and alkenyl succinate, is clearer in product color, and is used for improving the product quality.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a clean lubricant for gasoline and diesel in-cylinder direct injection engines and a preparation method thereof. Background technique [0002] With the continuous operation of the vehicle, the car engine will unknowingly produce sludge, carbon deposits and other substances that affect the normal operation of the car in the throttle body, fuel injector, cylinder and other departments inside the engine. When the engine is running, the temperature of the fuel injector is around 100°C, and the temperature of the intake valve is between 200-300°C. At such a temperature, the unstable components in the fuel are prone to oxidative condensation reactions, forming colloids and carbon deposits, which are deposited on the intake valves and fuel injection nozzles. Advanced high-pressure engines and GDI fuel direct injection Technical engines are more prone to carbon deposits. The deposits accumula...

Problems solved by technology

If the presence of sludge and carbon deposits is ignored, they slowly eat up engine power, reduce fuel economy, increase emissions of substances that pollute the environment, and can cause a series of engine failures
