Lubrication and wear reduction

There is a rapid relative sliding between the piston and the cylinder, and between the main shaft and the bearing bush. To prevent excessive wear of the part, an oil film is required between the two sliding surfaces. An oil film of sufficient thickness separates the surface of the relatively sliding part to reduce wear.

Cooling and cooling

The oil can bring the heat back to the sump and out to the air to help the tank cool the engine.

Cleaning and cleaning

Good oil can bring the carbide, sludge and wear metal particles on the engine parts back to the oil tank, and flush the dirt generated on the working surface of the parts through the flow of lubricating oil.

Sealed leakproof

The oil can form a seal between the piston ring and the piston to reduce gas leakage and prevent external contaminants from entering.

Rust and corrosion protection

Lubricating oil can absorb the surface of the part to prevent water, air, acidic substances and harmful gases from coming into contact with the parts.

Shock absorption buffer

When the engine cylinder pressure rises sharply, the load on the piston, piston chip, connecting rod and crankshaft bearing is suddenly increased. This load is transmitted and lubricated by the bearing to cushion the impact load.
