Revised engine
JohnDeere has launched a new 6.8 litre generator drive genset
engine, with a key power node of 250 kVA.
According to John Deere, the engine offers an exceptionally
high power density combined with outstanding fuel efficiency,
all in a smaller engine than normally required to power a 250
kVA generator.
The 250 kVA engine is available as a bare engine or as a power
unit that includes a factory-mounted cooling package and air
filter. The 250 kVA also offers switchable speeds of 1,500 and
1,800 rpm, whichmeans that the same engine canbe used in50
Hz or 60Hz applications.
For end-users, a generator set with a 6.8L 250 kVA engine
can be very compact, reducing footprint and installation costs.
The engine also boasts exceptional load acceptance and low fuel
consumption, while optional crank case ventilation keeps the
canopy environment clean.The engine’s electronic controls can
be synchronised toworkwithmultiple generators.
In EU countries, the new, non-certified 250 kVA prime/
275 kVA stand-by power engine is suitable for stationary
generator sets.
The Series 1600 engine fromMTU, part of RollsRoyce Power
Systems, is now being used in amarine genset.
The genset is basedon the 6-cylinder Series 1600 inline engine
delivering up to 323 kW output and compliant with IMOTier

The marine engine version is configured for onboard power

running costs, with maintenance intervals considerably longer
than average, and specific fuel consumption under 205 g/kWh
at full continuous power.
