First, lubrication

Lubricating oil can quickly form an oil film with a certain thickness on the metal surface moving to each other, avoiding the direct contact of the metal, thereby reducing wear, reducing drag and saving energy.

Second, heat conduction cooling

The lubricating oil has good fluidity. During the movement of the automobile system, the heat generated by the friction of each transmission member can be cooled, and the heat released by part of the engine (power stroke) is absorbed, and the temperature of the friction surface is greatly reduced. , thereby reducing the speed of wear and tear on the parts.

Third, purification parts

The lubricating oil itself has a super-clear and clear dispersing function. When the lubricating oil flows between the parts, the grinding debris, contaminants, sediments, etc. on the surface of the machine can be washed out, and a high-strength oil film is formed, thereby extending the machine. The service life of the piece.

Fourth, isolation seal

Lubricating oil can form a certain thickness of oil film on the cylinder or piston wall, which can form an oil seal with the piston, prevent gas leakage in the combustion chamber, reduce power loss, and maximize the power of the engine.

5. Damping and earthquake resistance

When the engine is doing work, the shaft tip, the large end of the connecting rod or the crankshaft are subjected to considerable impact force caused by rapid pressure. The lubricating oil can convert mechanical energy into hydraulic energy, and the oil film can reduce the contact surface. The impact force that it bears.

Sixth, anti-rust and anti-corrosion

Lubricating oil will form adsorbing oil on the surface of the machine to prevent water vapor and acid substances generated by combustion from being adsorbed on the surface of the machine to protect the engine.
