5.4 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.
 Adequate cooling of the turbocharger must be ensured after stopping the
engine.
 Run the engine for 5 ... 10 minutes at idling speed before stopping it.
 Observe the oil pressure specified for engine idling (see Table 5).
 For oil-cooled bearing casings, post-lubricate for 20 minutes if the turbine inlet temperature
(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 ro-
tors come to a standstill. ABB Turbo Systems recommends post-lubrication for 10 minutes.
 Observe the oil pressure specified for post-lubrication (see Table 5).
