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 MASS FLOW SENSOR

This sensor is mounted between air filter and

turbocharger. It gives Information about the amount

of air quantity & temperature entering the engine.

This input is used by the ECU for corrections of fuel

quantity based on amount of air availability for

optimization of exhaust gas circulation & the

turbocharger control. While assembling, the AMF

sensor the point of the arrow should be towards the

Turbo charger.
