Stopping the engine

Residual heat in the turbocharger
If the residual heat in the turbocharger is not adequately dissipated, it may
damage the engine.
CAUTION
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 ) 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 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).
