Water cooled engines: In water cooled engines, the water is used for the cooling of engine. The air cooled engines are generally used in motorcycles and scooters. In air cooled engines the cylinder barrels are separated and metal fins are used which provides radiating surface area that increase cooling. Air cooled engines: In these engines, the air is used to cool the engines.
On the basis of types of cooling, the engines are classified as:
