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
.
¡
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-
sure at oil inlet before turbocharger
