Status for operation
Not admissible → do not start engine (before start: preheat
oil)
Table 8: Lubricating oil temperature at the inlet
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 following table. The
specified oil outlet temperature is to be considered as alarm value for the turbocharger op-
eration and must be monitored according to the current regulations.

If the turbocharger has been operated for a longer period of time outside the admissible
range, ABB Turbocharging recommends having the turbocharger inspected by an ABB Tur-
bocharging Service Station.
