How Lubrication System Works In Engine?





Have You ever thought that, Why should we need to change the Engine Oil regularly?


You may know about maintaining your car that is you have to change the Engine lubrication oils time to time.The lubrication system is most important for Engine to work properly. It is the system by which the various rotating and sliding engine parts are lubricated to reduce the friction.Oil travels between the various parts as it flows through engine then it lubricates, cleans and smooths for moving parts in an engine as they cycle thousands of times every minute. And it controls the efficient temperature in an engine.The main task of Oil is to keep the things oily so they could not get dry.






The Lubrication system contains:


1. Oiling Pump.

2. Filtration.

3. Cooling.

4 Pressure relief valve.

5.Oil Pan.

6. PickUp Tube.

7. Spurt holes and galleries.




When the Engine is not running the Oil will be stays in the Oil pan which is located on bottom of the engine and servers as reservoir for oil and also it know as Sump. When the engine is started the oil is sucked out into the pump from the sump, through strainer linked directly linked to the crankshaft, and pressure is regulated by a relief valve.Then the oil is filtered by the oil Filters, to stops any dirt and debris from the oil may have picked up on its last pass through the system and cooled by the oil cooler.The oil pump pressurizes the oil, pushing it through the cylinder head and oil galleries.

The oil which is pumped to cylinder Head ,Oil Galleries  keeping the components continuously lubricated. And lubricates the Crankshaft Journal, and is then sent through the oil paths in the connecting rod in the form of oil jets to lubricate the cylinder and piston.

The flow of oil pumped to the cylinder head is regulated by oil control orifices in the cylinder block before being fed to the cam holders and rocker arm pivots.The oil fed to the holders lubricate the camshaft journals and some of the oil ejected out in the form of jet to lubricate the cams. The oil fed to the rocker arm pivot lubricates the pivot. After all the components lubricated , the oil returns to the Oil Pan again.



The Lubrication System of I.C Engines has the following advantages:
a. It reduces wear and tear of the moving parts.
b. It damps down the vibrations of the engine.
c. It dissipates the heat generated from the moving parts due to friction.
d. It cleans the moving parts.
e. It makes the piston gas-tight.
