All internal combustion engines are equipped with some type of cooling system
because of the high temperatures generated during operation. High temperatures are
necessary to produce the high gas pressures that act on the head of the piston.
Power cannot be produced efficiently without high temperatures. However, it is not
possible to use all of the heat of combustion without harmful results.
temperature in the combustion chamber during the burning of the fuel is well above
the melting point of iron. Therefore, if nothing is done to cool the engine during
and pistons will overheat, resulting in engine seizure.
This task will describe the principles, components, and operation of the cooling
