Cooling system• The cooling system is a system of parts and fluid that work together to

control an engine’s operating temperature for optimal performance

Reasons for providing cooling system• High temperatures reduce strength of piston & cylinder liner• Preignition of charge• Physical & chemical changes may occour in lubricating oil• The even expansion of piston in the cylinder

Types of cooling system • Air cooling system• Liquid cooling system Air cooling system In this method,air is carried away by the air flowing over& around the engine cylinder

Avantages & disadvantages Advantages:-• Simpler design • Absence of cooling

pipes,radiator,water jackets• No danger coolant leakage• Installation easier

Disadvantages:- Non-uniform coolingMaintenance is not easy

Liquid cooling system • In this method of cooling system engines, the cylinder walls and

heads are provided with jackets through which the cooling liquid can circulate.• The heat is transferred from cylinder walls to the liquid by convection

and conduction

Types:-• Thermo-syphon cooling • Forced or pump cooling • Cooling with thermostatic regulator • Pressurised water cooling • Evaporative cooling

• Thermo-syphon cooling

• Thermostat cooling

Advantages :-

• Fuel consumption low• Compact design of with appreciably smaller frontal area is possible• Conveniently located wherever required

Disadvantages• Water jacket is require• Highly cost• More maintenance
