There are two Types of Engine Cooling System; there are two types of cooling systems:


Air Cooling System


Liquid - Cooling system 


The Air Cooling System


Found mostly in older cars and motorcycles, an air-cooled system is where the engine block is covered in aluminium fins that conduct the heat away from the cylinder. A powerful fan forces air over these fins, which cools the engine by transferring the heat to the air.The amount of heat reduced by the air-cooling depends upon factors such as factors; the total area of the fin surfaces, the velocity / amount of the cooling air and also the temperature of the fins as well as the cooling air. Air-cooling is mostly used in less horsepower engines like, motorcycles, scooters, small cars and small aircraft engines where the forward motion of the machine gives good velocity to cool the engine. Air-cooling is also provided in some small industrial engines.


The Advantages of an Air Cooled System:


They are cheaper to manufacture. They need less care and maintenance. The design of air-cooled engine is simple. They are lighter in weight than liquid - cooled engines due to the absence of water jackets, radiator, circulating pump and the weight of the cooling water. This system of cooling is particularly advantageous where there are extreme climatic conditions in the arctic or where the evaporation factor of liquids is higher- deserts. There is no risk of damage from frost, such as cracking of cylinder jackets or radiator water tubes.


Liquid Cooling System:


The liquid cooled systems are the ones that are used the most these days. In an automotive with

Liquid Cooling System, the heat is carried away by the use of a heat absorbing coolant that circulates

through the engine, especially around the combustion chamber in the cylinder head area of the

engine block.
