TURBOCHARGER & INTERCOOLER
Turbocharger:
Your vehicle is fitted with a turbocharger.
This is an efficient supercharging device
used in the engine. It makes use of
thermal energy of engine exhaust gases
to run a turbine which in turn drives a
compressor to force air under pressure
into the inlet manifold.
Lubrication of Turbocharger:
The turbocharger rotor assembly is
supported by two fully floating bearing
bushes in the bearing housing. These
bearing bushes are lubricated with finely
filtered engine oil from the lubrication
system of the engine.
Idle the engine for a while (one minute)
after starting the engine and before
stopping the engine to ensure adequate
lubricating oil supply to the turbocharger.
Turbocharger Connections:
All turbocharger connections must be
leak-proof. Check air inlet, air outlet,
exhaust gas inlet and exhaust outlet
connections as well as oil inlet and outlet
connections and tighten the connections
where required.
Proper maintenance of air filter, oil filter
as well as use of correct grade of oil and
adherence to oil change intervals is
essential for proper functioning of the
turbocharger.
If you suspect any malfunctioning of the
turbocharger, take the vehicle to the
nearest dealer.
NOTE
Keep engine at idling speed for atleast
a minute after starting and also before
stopping, to protect the turbocharger
against damage due to oil starvation.
Intercooler :
Hot air coming out of turbocharger flows
through the intercooler and gets cooled
before entering the intake manifold.
As such it does not require any
maintenance however it can be cleaned
externally by blowing compressed air.
CAUTION
While cleaning, ensure that
intercooler fins are not damaged. If the
fins get damaged, it could lead to lose
of performance and subsequent
failure.
Maintenance recommendations:
a) Check the boost pressure pipe for
its proper fitment, damage etc.
b) Specified engine oil and the oil filter
should be used and should be
changed regularly in accordance
with Service Schedule.
c) Check oil feed pipes, return pipes,
air intake and exhaust piping for
leakages and restrictions.
d) Check the engine breathing system
and oil seperator.
e) Fill the oil inlet hole of the
turbocharger with clean engine oil,
when the engine is started after long
storage.
NOTE
In cold condition, first 2 sec. engine
should not run up to full throttle.
