6 Monitoring during operation
Lubricating oil temperature at the inlet
Engine damage and injury to personnel
If the oil temperature at the oil inlet exceeds the admissible range, this may
lead to engine damage and injury to personnel.
WARNING
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 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 spe-
cified 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
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 Tur-
bocharging Service Station.
