Rating
for natural gas operation
68 kW / 92 HP at 1500 rpm
The power output specifications are valid for operation with natural gas with a calorific value of
36,350 kJ/m3 and a methane number > 80. For higher calorific values, the engine is to be set so
that the specified engine power is not exceeded. For lower calorific values a correspondingly lower
engine power will be the result. A new engine setup will be needed to achieve the rated output.
