Introduction
In Lesson one, the principles, components, and operation of diesel and gasoline
engines were described. The knowledge obtained from this information can be used
to understand the subsystems of the internal combustion engines discussed within
this lesson. These subsystems are: intake system; exhaust system; turbochargers;
lubrication system; and cooling system.
This task will introduce and describe the intake system, turbochargers, and exhaust
system.
