4. INTRODUCTION
4
. Engine is made of many moving parts
. Due to continuous movement of two
metallic surface over each other , there
is wearing of moving parts , generation
of heat and loss of power in the engine
.Lubrication of moving parts is
essential to prevent all these harmful
effects

5. LUBRICATION SYSTEM
5
Lubrication is the action of applying a
substance such as oil or grease to an
engine or component so as to minimize
friction and allow smooth movement.
Lubricating system is a mechanical
system of I.C. combustion engine in
which a pump forces into a engine parts.

6. PURPOSE OF LUBRICATION
6
> To reduce the friction between moving parts.
> To increase the efficiency.
> To minimize the vibrations.
> To reduce the corrosion and carbon deposit.
> To reduce the heat of moving parts.
> To reduce the noise.
> To provide cooling to the engine.
> Working as a cleaning agent.
> Working as a sealing agent.
> Working as a shock absorber.

7. PROTECT
•Thin film prevents metal
to metal contact.
7
•Protect
surfaces
high load
where oil is
“wiped” from the metal.
•Prevent corrosion of
iron,copper, aluminium,
lead and other metals.

8. Why do we use Lubricants ?
Reduce Heat
Reduce Wear
Reduce Noise
A lubricant is any material that has the effect of
reducing friction. By reducing friction, we
reduce heat, noise and most importantly wear.

SOLID LUBRICANTS
eg. graphite , molybdenum , mica
SEMI SOLID LUBRICANTS
eg. Heavy grease
LIQUID LUBRICANTS
eg. oil

The duties of the lubricant in an engine are
many and varied in scope . The lubricant is
called upon to control the following -:
1.Friction between the components and metal
to metal contact.
2.Overheating of the components .
3.Wear of the components
4.Corrosion
5.Carbon deposits

11. Lubricating System Parts
22
• Oil sump
• Oil pump
• Pick-up screen
• Pressure regulator
• Oil filter
• By-pass valve
• Oil galleries
• Dipstick
• Pressure indicator

12. Advantage:
Simplicity and Low cost as it does not
require an oil pump, filter, etc.
Disadvantages:
Cause heavy exhaust smoke due to burning
of lubricating oil
Forms deposit on piston crown and exhaust
port which affect engine efficiency.
