TURBO CHARGER

TURBOCHARGER :

Turbocharger is an efficient supercharging device used in
our 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 rotor assembly of the turbocharger is supported by
two floating lead bronze sleeve bearings in the bearing
housing. These bearings are lubricated with the linest filtered
and cooled oil from the lubrication system of the engine.
There is a heat shield arrangement provided between the
gas chamber of the turbine and the bearing housing to avoid
heating of the bearings.

Maintenance of Turbocharger :
1. Tighten the following fasteners at PDI and thereafter at
every 10,000 km.
• Turbocharger mounting
• Turbocharger hose connections and its mountings
2. Check intercooler fins for any dust accumulations and
clean by compressed air at every 20,000 km. (if fitted)
3. It is advisable to run the engine at idle speed for about
one minute, after starting and before stopping the
engine. This ensures adequate lubricating oil supply
to the turbocharger.
