Abstract

The invention discloses a lubricant composition for an adiabatic gasoline engine. Perfluoroalkyl group ether and oil-soluble polyether are adopted as base oil and are matched with a plurality of composite additives; the lubricant composition comprises an antiwear agent, an antioxygen preservative, an anti-foaming agent, a viscosity index improver, a metal deactivator, a clearing agent, a dispersing agent, an antioxidant and a reinforcing agent. The lubricant composition disclosed by the invention has excellent cleaning and dispersing effects, viscosity-temperature characteristics, base number retentivity, acid neutralization capacity, good high-temperature resistant oxidation stability, high shear stability, good elastomer compatibility, good cooling property, good cold cranking capacity and excellent fuel economy, and is free of corrosion on moving parts; enough oil film strength of oil is ensured; and abrasion is reduced.

Description

technical field [0001] The invention belongs to the field of lubricants for internal combustion engines, in particular to a lubricant composition for adiabatic gasoline engines. Background technique [0002] Gasoline engine is an ignition engine fueled by gasoline, which can be divided into two-stroke and four-stroke according to different working strokes. A gasoline engine in a general sense mainly refers to a four-stroke gasoline engine. It has the characteristics of high speed, light weight, low noise, easy start, and low manufacturing cost. It is the main power of cars and light vehicles. The working cycle of a two-stroke gasoline engine is relatively simple. The crankshaft rotates once, and the piston goes up and down once to complete a working cycle. It has the characteristics of light weight, low price and high noise. It is often used as the power for motorcycles, chain saws and other low-power power machinery. [0003] The engine is the "heart" of vehicles, ships ...
