FUNCTION OF LUBRICATION AN INTERNAL COMBUSTION ( I.C ) ENGINE



# NEED FOR LUBRICATION.




In an I.C engine moving parts rub against 


each other causing frictional force.


DUE TO FRICTIONAL FORCE HEAT IS 


GENERATED AND THE ENGINE PARTS 


WEAR EASILY.


POWER IS ALSO LOST DUE TO FRICTION.





TO REDUCE THE POWER LOST AND 


WEAR AND TEAR OF THE MOVING 


PARTS A SUBSTANCE CALLED 


LUBRICANT IS INTRODUCED BETWEEN 


THE RUBBING PARTS OF THE ENGINE.








# FUNCTIONS OF LUBRICATION.

1.) IT REDUCES FRICTION BETWEEN MOVING PARTS.

2.) IT REDUCES WEAR AND TEAR OF MOVING PARTS.
3.) IT MINIMIZES POWER LOSSES DUE TO FRICTION.
4.) WHILE LUBRICATING IT ALSO CARRIES SOME HEAT FROM THE
MOVING PARTS AND DELIVERS IT TO THE SURROUNDINGS
THROUGH THE BOTTOM OF THE ENGINE (CRANK CASE).
5.) IT REDUCES NOISE CREATED BY MOVING PARTS.
6.) IT ACTS AS A CLEANING AGENT.
7.) PROTECT ENGINE PARTS FROM RUSTING.
