5 Monitoring operation / 5.1 Oil pressure, oil temperature
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.
u
Status for operation
Admissible
Temporarily admissible (< 1 h) → alarm
Not admissible → stop engine
Temporarily admissible when the engine is started → prior
to start: generally preheat oil
Table 9: 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.
Status for operation
Admissible
Temporarily admissible (< 0.5 h) → alarm
Not admissible → stop engine
Admissible
Temporarily admissible → alarm
Table 10: Lubricating oil temperature at the outlet
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.
