Why Apply Lubrication to Engine Parts ?

Lubrication is the supply of oil between two surfaces that have relative movement.

When applying lubrication to engine parts, one should choose a good lubricant to make the engine run efficiently.

Applying Shell oil to engine part

The objective of applying lubrication to engine parts are:

• Reduce the frictional forces between the parts by having a relative motion by minimizing the force of friction and ensuring the engine's smooth running.
• To reduce the wear and tear of moving parts.
• To cool the surfaces by carrying away the heat generated due to friction.
• Seal a space adjoining the surfaces, such as piston rings and cylinder liners.
• To absorb the shocks between bearings and other parts and reduce noise.
• To act as a cleaning agent and remove dirt, grit and any deposits that might be present between the moving parts of an automobile.
• To help the piston rings seal the gases inside the piston cylinder.

Parts of the Engine require lubrication:

The main parts of the engine which need lubrication are:

• Main crankshaft bearings.
• Big end bearings or crank pins.
• Gudgeon in bearings.
• Piston rings and cylindrical walls.
• Timing gears.
• Camshaft and camshaft bearings.
• Valve mechanism
• Valve guide, valve tappets, rocker arms.
• Governor and
• Water pump bearing.
