Answer to Question #275684 in Mechanical Engineering for RAVI

Question

What are different methods adopted in cooling of an I.C engine. Explain in details.

Answer 1

The Engine cooling system is one of the necessary things that is present in the Internal Combustion Engine to reduce the temperature of the components inside the engine. It also helps to reduce the wear out of the component and provide smooth functioning and long life of the components.

Air Cooling system:

In this system, the heat from the engine is directly dissipated to the atmosphere.

The Basic Principle of this type of system is to allow a flow of current through the parts from which heat is to be dissipated, which depends upon the surface area of metal in contact rate of flow of air, a temperature difference between hot surface and air. 

And Surface area of metal will be increased by providing the fins around the cylinder which is made of copper or steel.

Water Cooling System:

This type is the most commonly used type of system.

In this system dissipation of heat is done by the circulation of water through the jackets around the cylinder and passes this hot water through the radiator where air absorbs heat from the water.

There are two types of water cooling systems. 

Thermosyphon

Pump circulation system
