Stopping the engine
Stopping the engine
In the turbocharger, the heat from the lubricating oil that continues to circula-
te must be dissipated.
CAUTION
Let the engine continue to run at idling speed for 5 to 10 minutes before
stopping it.
Observe the oil pressure specified for engine idling (see Table 5).
Post-lubrication
Post-lubrication is not required and not recommended for water-cooled bearing casings.
For oil-cooled bearing casings, post-lubrication is mandatory for 20 minutes if the turbine
inlet temperature (t
– 550 °C with insulated casing
– 600 °C with non-insulated casing
At temperatures below the specified values, post-lubrication for 10 minutes is recom-
mended.
Observe the oil pressure specified for post-lubrication (see Table 5).
