Group 25 Intake and Exhaust System Design and Function
Turbocharger
The turbocharger is driven by the exhaust gases from
the engine passing through the turbine housing on their
way out into the exhaust system.
The flow of exhaust gases causes the turbine wheel in-
side the turbine housing to rotate. On the same shaft as
the turbine wheel is a compressor wheel. The compres-
sor wheel is mounted in a housing which is connected
between the air cleaner and the intake manifold.
When the compressor wheel starts to rotate, air is drawn
in from the air cleaner, compressed and forced into the
cylinders of the engine — but not before it has been
cooled down after passing through the charge air cooler.
