Lubricating oil temperature at the inlet
Machine damage may result if the oil temperature at the oil inlet ex-
ceeds the permissible range.
Keep the oil temperature at the oil inlet as specified in the following
table.
Oil temperature at inlet
T

Temporarily permissible (< 1 h) → alarm > 105 °C
Not permissible → stop engine
Not permissible → do not start engine (before
starting: preheat oil)
< 30 °C
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 fol-
lowing table. The specified oil outlet temperature must be regarded as an
alarm value for turbocharger operation and be monitored in accordance
with standard regulations.
Oil temperature at outlet

Permissible ≤ 160 °C
Temporarily permissible → alarm > 160 °C
Not permissible → stop engine > 180 °C

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.
