Let us tell you that all types of engines in vehicles nowadays, engine oil is used for lubrication in all. This engine oil gets heated by the constant movement of the parts inside the engine which these techniques need to keep cool. Although the engine will be air cooled, oil cooled or liquid cooled, it depends on how expensive the bike is or how big the engine of the bike is.
air cooled engine
As the name suggests, air-cooled engines use flowing air to cool the motor. Generally air cooled engine is given in most of the bikes. Due to this technology being cheap, it is used in affordable bikes.
This engine is usually seen in 100cc to 200cc bikes. Air cooled engines have several lines called fins. Through these lines, air is applied to the surface of the engine, which keeps the engine oil cool. Air-cooled engines are more economical and lighter than all three types of engines as they do not require any additional equipment.
oil cooled engine
Oil cooled engines are similar to air cooled engines in that they also use air cooled fins for cooling. However, they have a small externally mounted radiator that helps keep the engine oil cool. In this technique, hot engine oil goes through the pipe to the radiator and after being cooled by air goes back to the engine.
This process continues while the bike is running and the engine remains cool. Oil cooled engines are commonly seen in bikes with a capacity of more than 150cc.
liquid cooled engine
Liquid cooled engines are commonly used in cars, buses and trucks. However, with the ease of technology, they are now being used in two wheelers as well. Liquid-cooled engines are widely used by almost all the automobile companies around the world.
In this system liquid coolant is used to keep the engine cool. This coolant is fed into the radiator outside the engine. There are many small pipes attached to the inside of the radiator, which circulates the engine oil inside and cools it back to the engine.
This technology is effective in keeping the engine cool effectively. Usually, liquid cooled engines are given in bikes with a capacity of more than 200cc. Bikes with liquid cooled engines are expensive. Liquid cooled engines are provided in large engine touring bikes.
