Lubricating oil temperature at the outlet
The oil temperature at the outlet depends mainly on:
 lubricating oil temperature and pressure at the oil inlet
 engine load and turbocharger speed
 exhaust gas temperature
The maximum permissible oil temperature at the outlet is listed in the
following table. The specified oil outlet temperature must be regarded as
an alarm value for turbocharger operation and be monitored in
accordance with standard regulations.
Status for operation
Permissible
Temporarily permissible → alarm
Not permissible → stop engine
Permissible

If the turbocharger has been operated outside the permissible range for a
prolonged period of time, ABB Turbo Systems recommends having the
turbocharger inspected by an ABB Turbocharging Service Station.
