Cleaning, cooling, lubricating
The same as the filter in a car engine... to screen out impurities from the oil in case it damages the engine.
Regularly changing a car's engine oil is necessary to ensure proper engine function as well as to ensure that a vehicle engine lasts for as long as possible.

Acids build up in the oil which will cause damage to moving parts.

To move the oil throughout the engine under pressure. This lubricates and helps cool the engine.
The engine oil pan helps in storing extra oil for the car engine. This stored oil can be used for lubricating the engine. The oil pan is placed at the end of the engine. Generally you will find two types of oil pan, namely dry and wet pan. It also helps in covering the bottom area of the car engine.
The oil galley is the passages through which oil flows throughout the engine.
