12.32 Lubrication Systems - Engines

12.32.2 State the functions of an engine lubrication system.

The engine lubrication system serves several important functions in an internal combustion engine:

1. Lubrication:

The primary function of the engine lubrication system is to lubricate the moving parts of the engine, such as the crankshaft, connecting rods, pistons, and camshaft.

This reduces friction between the moving parts, which reduces wear and tear and helps to extend the life of the engine.

2. Cooling:

The engine lubrication system also helps to cool the engine by carrying heat away from the moving parts.

This is especially important in high-performance engines that generate a lot of heat.

3. Cleaning:

The engine lubrication system helps to keep the engine clean by carrying away dirt, debris, and other contaminants that can build up over time.

This helps to prevent damage to the engine and ensures that it runs smoothly and efficiently.

4. Sealing:

The engine lubrication system also helps to seal the engine by forming a thin film of oil between the moving parts.
