5. A system, which controls the engine
temperature, is known as a cooling system.
Cooling system is the control of the internal
combustion engine parts to prevent over
heating and to maintain all operating
dimensions by a circulating coolant, oil and a
fan.

6. To maintain correct engine operating temperature.
To maintain proper lubrication of engine parts.
 To maintain an optimal engine temperature.
Optimal engine temperature is high enough to help
emissions and not too high to cause damage to the
engine.

7. a. Air cooling (or direct cooling) system
b. Water cooling (or indirect cooling) system

8. Air cooled engines depends on air flow across
their external surfaces of the engine cylinders to
remove the unnecessary heat. It is used for small
engines.
Example: Motor Cycle, Aero plane etc.

9. 1. Cooling fins 2. Beffles

10. Less weight & Low cost
In places where water is scarce, air cooled
engine is very effective
Have no coolant leakage or freezing problems
Less equipment involved
Easy mechanism
No extra power required

11. Large amount of power is used to drive
the cooling fan.
Give low power output
Cooling is not uniformed
Sometimes amplify the noise level.

12. An internal combustion engine with a jacket cooling
system in which liquid, usually water, is circulated to
maintain acceptable operating temperature of machine
parts.
It is used for large engines.
Example: Power tiller. bus, track etc.

13. Water Jackets Water pump
Fan Thermostate Radiator

15. Uniform cooling of cylinder, cylinder head and
valves.
Better fuel consumption of engine
Higher heat transfer rates compared to air
cooling
Engine is less noisy

16. *Depends upon the supply of water
*Requires more maintenance and care for its parts
*Extra power is required to drive the liquid
*The water pump which circulates water absorbs
considerable power.
