Vacuum Modulator
Turbocharger Intercooler
The charging efficiency may be lowered or the
knocking may happen as the intake air is
heated and the density of air is lowered. The
intercooler is the device which cools the
supercharged air.

(2) Turbocharger Intercooler Assembly
The turbocharger is designed to improve the engine power by introducing more air (oxygen)
into the engine.
However, the intake air is heated during the compression process in the turbocharge
r
compressor and the density is lowered.
The intercooler is the device which cools (50 ~
the air entering the engine from
high temperature (100 ~
to maintain the turbocharging efficiency.
Thus, more air is entered the cylinder than the engine only with the turbocharger to give more
power.
