COMPONENTS
A. AIR FILTER
The Air filter is of dry type. The purpose of the air
filter is to clean the atmospheric air from dirt & dust
before entering the engine cylinder. Air filter needs
to be cleaned periodically and replaced at recom-
mended intervals.
For air filter cleaning and air filter element replace-
ment, please refer the “On vehicle service” section
of this manual.
B. INTAKE MANIFOLD
The intake manifold is located between the air in-
take pipe supplying air from the intercooler and
cylinder head. It is mounted on the cylinder head.
The air from the air filter flows to the engine cylinder
through the air intake manifold.
C. 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. The in-
tercooler is mounted in front of the radiator.
D. AIR TEMPERATURE SENSOR
Air temperature sensor is mounted on the air intake
elbow. It measures temperature and pressure of
fresh air. On the basis of which EMS ECU estimates
the air flow and compares with actual air flow
measured from Air mass flow sensor (AMF).
