Motorcycle Engine Liquid Cooling System

(Last Updated On: 01/02/2018)

 

Usually, a motorcycle engine burns the fuel using air and produces power to derive the motorcycle on the road. Therefore, air and fuel mixture that compressed in the combustion chamber inside the motorcycle engine and then it burns and produces the power. That power drives the engine parts and finally delivered to the wheel and a motorcycle moves.

In the combustion process, the engine also generates a huge amount of temperature besides producing power. So, a standard temperature condition is required for the efficient combustion to operate the motorcycle engine. Also, the running engine produces excessive heat over the standard limit which is harmful to an engine. Therefore, the motorcycle engine cooling system works here to control the temperature within the standard limit cutting off the excess heat.

In general, there is two basic cooling system in a motorcycle engine cooling system. The air cooling and liquid cooling is very well known cooling feature for a motorcycle engine.

Liquid Cooled Engine

As a motorcycle engine cooling system, sometimes known as a water-cooled engine. Mostly, water-based cooling liquid used for this type of cooling system.

In liquid-cooled motorcycle engine, the engine block or cylinder head has no metal fin like the air-cooled engine. It comes with straight and solid construction from outside. But it has water tunnel around the cylinder block and cylinder head.

That tunnel is connected to a liquid coolant reservoir and cooling radiator. The radiator is attached facing the high airflow line and also have an additional cooling fan to make the liquid forcefully cool inside the radiator.

Motorcycle Liquid Cooling System

In the liquid cooled motorcycle engine, there is a closed loop of liquid coolant. There also attached a mechanical pump which circulates the liquid coolant within the loop. The pump circulates the liquid toward the engine block, then to the cooling radiator and then the reservoir and aging toward the engine. Thus the cycle continues.

Here in this system, the liquid coolant absorbs the excess heat when flowing through cylinder block or head. It releases that heat when passing through the cooling radiator. Thus it cools the engine and controls the temperature.

Here in case of overheat situation, the attached thermostat relays the signal to ECU. Accordingly, the coolant pump circulates the cooling liquid faster or if needed the radiator cooling fan starts to work to get the hot liquid from the radiator cools faster. So you can see how precisely the liquid cooling system works.
