Lubricating oil temperature at the inlet
CAUTION
Machine damage
If the oil temperature at the oil inlet exceeds the admissible range, this may
lead to engine damage.
Observe oil temperature at the oil inlet according to the following table.
Status for operation

Admissible
30 … 105 °C
Temporarily admissible (< 1
h) → alarm
> 105 °C
Not admissible → stop engine
> 110 °C
Not admissible → do not start engine (before start: preheat oil)
< 30 °C
Table 7: 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
operation and must be monitored according 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 turbocharger inspected by an ABB
Turbocharging Service Station.
