1.5L REVOTORQ ENGINE

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. T-MAP SENSOR

T-Map sensor is mounted at 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).
