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.
