How is heat removed from the engine?

Answer 1

Heat can be removed from engine in three different ways.

· Conduction : transfer of heat through solid

· Convection : heat transfer by movement of molecules of substance

· Radiation : transfer across spaces as rays such as use of fins.

But, in internal combustion engine, usually heat is removed by passing coolant through air passages around engine blocks through radiator which absorb the heat by air passing over the fins and through radiator core.

Air flow is assisted by Fans.
