46.How to Cut off Damaged Turbochargers

Engines with one turbocharger (Engines with exhaust by-pass)

1. Stop the engine.
2. Lock the turbocharger rotor.
3. Remove the blanking plate from the exhaust by-pass pipe.
4. Remove the compensator between the compressor outlet and the scavenge air duct. This reduces the suction resistance.
5. Run engine with 15% of MCR load and 53% speed.

Engines with one turbocharger (Engines without exhaust by-pass)

1. Stop the engine.
2. Remove the rotor and nozzle ring of the turbocharger.
3. Insert blanking plates.
4. Remove the compensator between the compressor outlet and the scavenge air duct. This reduces the suction resistance.
5. Run engine with 15% of MCR load and 53% speed.

Engines with two or more turbochargers

1. Stop the engine.
2. Lock the rotor of the defective turbocharger.
3. 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)
4. Run engine with 20% of MCR load and 58% speed.
