PRIN. OF INTERNAL COMBUSTION ENGINES - OD1619 LESSON 2/TASK 3
Describe the principles, components, and operation of the cooling
Within a selfstudy environment and given the subcourse text, without assistance.
Within one hour
No supplementary references are needed for this task.
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. The
the melting point of iron. Therefore, if nothing is done to cool the engine during
operation, valves will burn and warp, lubricating oil will break down, and bearings
and pistons will overheat, resulting in engine seizure.
This task will describe the principles, components, and operation of the cooling
