Components :
a) Intake Manifold :
The intake manifold is fitted between the
electronic throttle valve through intake adaptor
pipe and the cylinder head. The compressed air
from turbocharger via intercooler is metered
through an electronic throttle valve into the
combustion chambers of the four cylinders
through intake manifold.
b) Intercooler :
The intercooler is a heat exchanger used to cool
the compressed hot air coming from the
turbocharger
before it enters the intake manifold.
It increases the density of the air and avoids the
chance of pre-ignition due to high intake air
temperature.
A Temperature and manifold air pressure sensor
(TMAP sensor)
is mounted on the outlet of the
intercooler to measure the boost pressure.
For
more information on TMAP sensor refer EMS
section in this group.
