Lubricating oil temperature at the outlet
The oil temperature at the outlet is mainly dependant on:
 Lubricating oil temperature and pressure at the oil inlet
 Engine load and turbocharger speed
 Exhaust gas temperature
The maximum admissible oil temperature at the outlet is listed in the fol-
lowing table. The specified oil outlet temperature is to be considered as
alarm value for the turbocharger operation and must be monitored accord-
ing to the current regulations.

Permissible ≤ 145 ≤ 130
Temporarily permissible -> alarm > 145 > 130
Not permissible -> stop the engine > 165 > 150
If the turbocharger was operated for a longer period of time outside of the
admissible range, ABB Turbo Systems recommends to have the turbo-
charger inspected by an ABB Turbocharging Service Station.
