Monitoring during operation
4.1
Oil pressure, oil temperature
Lubricating oil pressure before turbocharger
CAUTION
Assuring lubricating oil pressure
Serious damage to engine or property can result from missing or insufficient
lubricating oil supply.
The lubricating oil pressure must be monitored during operation and the
necessary pressure assured at the oil inlet.
Status for operation
Oil pressure before turbo-
charger
[bar]
Admissible, for normal operation,
with an oil temperature range at the inlet of 30 ... 70 °C
0.8 … 2.5
Admissible, for normal operation,
with an oil temperature range at the inlet of 70 ... 85 °C
0.8 … 2.0
Admissible, during engine warm-up
0.8 … 4.0

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.
