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
u
table.
Status for operation
Admissible
Temporarily admissible (< 1 h) -> alarm
Not admissible -> stop engine
Not admissible -> do not start engine
(before start: preheat oil)
Lubricating oil temperature at 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 fol-
lowing table. The specified oil outlet temperature is to be considered as
alarm value for the turbocharger operation and must be monitored ac-
cording to the current regulations.
Status for operation
Permissible
Temporarily permissible -> alarm
Not permissible -> stop engine
If the turbocharger has been operated for a longer period of time out-
side the admissible range, ABB Turbocharging recommends having the
turbocharger inspected by an ABB Turbocharging Service Station.
