Lubricating oil temperature at 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 ac-
cording to the current regulations.

If the turbocharger was operated for a longer period of time outside of
the admissible range, ABB Turbo Systems recommends to have the tur-
bocharger inspected by an ABB Turbocharging Service Station.
