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 2 … 10 minutes at idling speed before stopping it.
u
Observe the oil pressure specified for engine idling
(see Table 8: Lubricating oil pressure
at oil inlet before turbocharger
¡
Post-lubricate water-cooled bearing casings until the rotors come to a standstill. Deac-
tivate post-lubrication as soon as the rotor comes to a standstill. Deviating procedures
must be coordinated with Turbo Systems.
¡
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. Turbo Systems recommends post-lubrication for 10 minutes.
u
Observe the oil pressure specified for post-lubrication
(see Table 8: Lubricating oil pres-
sure at oil inlet before turbocharger
