CAUTION
Residual heat in the turbocharger
If the residual heat in the turbocharger is not adequately dissipated, it may
damage the engine.
Adequate cooling of the turbocharger must be ensured after stopping
u
the engine.
Run the engine for 5 ... 10 minutes at idling speed before stopping it.
u
Observe the oil pressure specified for engine idling
u
at oil inlet before turbocharger
¡ For oil-cooled bearing casings, post-lubricate for 20 minutes if the turbine inlet temper-
ature (t ) exceeds the following values when the engine is stopped:
TE
– 550 °C with insulated casing
– 600 °C with non-insulated casing
At temperatures below the specified values, post-lubrication must be ensured until the
rotors come to a standstill. ABB Turbocharging recommends post-lubrication for
10 minutes.
Observe the oil pressure specified for post-lubrication
