Maximum operating speeds:
4500 rpm (intermittent) – 4000 rpm (continuous)
The values are expressed in kW according to the manufacturer’s specifications.
For diesel engines, generally operating at lower speeds compared to smaller units, these values can be used as a reference for gearbox selection, taking into account engine characteristics and operating conditions.
Torque (Nm) depends on engine speed and is not a fixed value.
