PRIN. OF INTERNAL COMBUSTION ENGINES - OD1619 LESSON 2/TASK 3
engine always uses an air cooling system. There is also a certain amount of
cooling as the fuel vaporizes in the intake manifolds and combustion chambers.
e. Virtually all aircooled engines use an oil cooler to help in the cooling
process. The oil cooler unit is usually located in the ducting so that it is
exposed to the forced air from the cooling fan. Its operation is the same as that
described in paragraph 3f of Lesson 2 Task 2 on page 73.

Conclusion
This concludes the discussion of the cooling system and the subsystems of the
internal combustion engine. The information provided in this subcourse should give
the mechanic a general idea of the principles and operation of an internal
combustion engine and its subsystems. For a more complete understanding of
internal combustion engines, their operations, and components, the mechanic should
refer to TM 98000.
