4 Monitoring operation
Lubricating oil temperature at the inlet
Machine damage
If the oil temperature at the oil inlet exceeds the admissible range, this may
lead to engine damage.
CAUTION
Observe oil temperature at the oil inlet according to the following table.

Status for operation
Admissible
Temporarily admissible (< 1 h) → alarm
Not admissible → stop engine
Not admissible → do not start engine (before start: preheat oil)
Table 6: 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 spec-
ified oil outlet temperature is to be considered as alarm value for the turbocharger operation
and must be monitored according to the current regulations.
Status for operation
Admissible
Temporarily admissible → alarm
Not admissible → stop engine
Admissible
Temporarily admissible → alarm
Table 7: Maximum lubricating oil temperature at the outlet
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 Turbocharg-
ing Service Station.
