Need of Lubrication System in Engine and its Function.

Lubrication System 

The engine is made of many moving parts and these parts are in continuously moving condition. when the two or more parts meet then there is friction and wearing take place, generation of heat and the loss of power in the engine. Hence the lubrication system is necessary to prevent the engine from these harmful effects.

The system which is used to introduce the lubricant to the engine is called the lubrication system.

lubrication system introduced the oil and other lubricants to give a flow to the clean oil at the desired temperature with an appropriate pressure to the moving parts for the smooth function of the moving parts to avoid the harmful effects.

Mainly these losses take place-

1. Direct frictional losses
2. Pumping losses
3. Losses due to driving components

The function of the Lubrication system

1. Reducing frictional effect 
2. cooling effect 
3. sealing effect
4. cleaning effect

lubrication

1. Reducing frictional effects:

when the two moving parts meet rubbing take place and high amount of heat generated. two rubbing surface always produce friction and this friction leads to wear.friction between two parts directly affect the performance of the engine so it must be reduced as far as possible for the smooth function of the engine. this problem can eliminate the proper distribution of the lubricant on the moving parts.

2.Cooling effect:

When the moving parts move like the piston inside the cylinder, piston comes in touch with the cylinder and rubbing take place, parts get heated up.Hence the lubrication is used to cool the engine parts.

3.Sealing effect

as the term itself define the function, there is some gap is found between the parts then there is the possibility of gas leakage from the engine. The gap between the cylinder, and liner, piston and piston ring etc. Hence the cooling system prevents the leakage.

4. Cleaning effect

when the engine is in moving condition, foreign dust particle gets deposited on the surface of the moving parts which can affect the performance of the engine. proper cooling takes away these unwanted particles from the surface.
