6.4 Stopping the engine
CAUTION
Residual heat in the turbocharger
If the residual heat in the turbocharger is not adequately dissipated, it may
damage the engine.
u Adequate cooling of the turbocharger must be ensured after stopping
the engine.
u Run the engine for 5...10 minutes at idling speed before stopping it.
u Observe the oil pressure specified for engine idling (see Table7: Lubricating oil pressure
at oil inlet before turbocharger →44).
¡ For oil-cooled bearing casings, post-lubricate for 20minutes if the turbine inlet temper-
ature (t
TE
) exceeds the following values when the engine is stopped:
– 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.
u Observe the oil pressure specified for post-lubrication (see Table7: Lubricating oil pres-
