3. LUBRICATION

1)Anti-friction

The oil makes a thin film on the surface of sliding components to reduce the wear due to friction.

2)Cooling

The friction makes the heat on the components. The oil absorbs the heat and radiates it or cools it down.

3) Sealing

The piston ring on the piston seals the cylinder. The oil gets into the clearance in piston ring to secure

the sealing for compression pressure and combustion gas.

4) Anti-corrosion

The oil generates the thin film on the surface of components to prevent the material from contacting with

air, water and corrosive gas.

5) Cleaning

The oil transfers the residue of material due to friction, oxidized substance, and carbonized substance

while circulating in the engine by oil pump.
