General information
General Information
This engine is water-cooled. It uses coolant to cool the
engine by absorbing heat from the combustion chamber and
the engine oil and then releases the heat, allowing for normal
engine operation.
In this cooling system, coolant provided by the coolant pump
flows into the oil cooler through the coolant pipe to absorb oil
heat and passes through the coolant jacket of the cylinder
block and the cooling path of the cylinder head to absorb the
combustion heat.
Coolant which absorbed the oil and combustion heat flows
into the water temperature controller through the coolant
pipe. If the coolant temperature is lower than the
valve-opening temperature of the water temperature
controller, the coolant flows into the coolant pump. If higher,
it flows into the radiator. The radiator releases the heat
absorbed from the coolant and sends the coolant to the
coolant pump again.
