Adequate cooling of the turbocharger must be ensured after stopping
u
the engine.

¡
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 ABB Turbo Systems.
¡ For oil-cooled bearing casings, post-lubricate for 20 minutes if the turbine inlet temper-
ature (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
rotors come to a standstill. ABB Turbo Systems recommends post-lubrication for
10 minutes.
