•
For an engine with three turbochargers and one or two turbochargers are defective:
-
Make sure that the exhaust gas temperature at the serviceable turbochargers inlet is
less than the maximum permitted temperature.
-
If one turbocharger is defective, the maximum power output of the engine is
approximately 66% related to the power of the serviceable turbochargers.
-
If two turbochargers are defective, the maximum power output of the engine is
approximately 33% related to the power of the serviceable turbocharger.
-
For a DF engine, the engine can operate in diesel mode, gas mode, or fuel sharing
mode.
•
If all turbochargers of the engine are defective:
-
The maximum power output of the engine is between 10% (as a minimum) to
approximately 15% related to the power of the auxiliary blowers.
8.3.2.2
One or more cylinders are unservicable
Obey the rules for operation, if one or more cylinders are unserviceable:
•
Operate the engine only at decreased load.
•
It is possible that the turbochargers surge. This makes a loud sound and causes large
differences in the scavenge air pressure. In this condition decrease the load of the engine
sufficiently.
•
It is possible that the engine had stopped in a position from which it cannot start. In this
condition start the engine momentarily in the opposite direction to get the crankshaft to a
different position.
8.3.2.3
Cooling water flow is decreased
If the cooling water flow is decreased, operate the engine only at decreased load.
