Engines with
one turbocharger (Engines with exhaust by-pass)
- Stop the
engine.
- Lock the
turbocharger rotor.
- Remove the
blanking plate from the exhaust by-pass pipe.
- Remove the
compensator between the compressor outlet and the scavenge air duct.
This reduces the suction resistance.
- Run engine
with 15% of MCR load and 53% speed.
Engines with
one turbocharger (Engines without exhaust by-pass)
- Stop the
engine.
- Remove the
rotor and nozzle ring of the turbocharger.
- Insert
blanking plates.
- Remove the
compensator between the compressor outlet and the scavenge air duct.
This reduces the suction resistance.
- Run engine
with 15% of MCR load and 53% speed.
Engines with
two or more turbochargers
- Stop the
engine.
- Lock the
rotor of the defective turbocharger.
- Insert
orifice plates in the compressor outlet and the turbine inlet. (A small
air flow is required to cool the impeller, and a small gas flow is
desirable to prevent corrosion)
- Run engine
with 20% of MCR load and 58% speed.
