NB (ISO 3046 - 1 IFN)
NA (ISO 3046 - 1 ICXN)
Mt-N Torque at N power.
C Specific fuel consumption at N power.
U1: Standard utilization range of engines rated at 3000 rpm
U2: Standard utilization range of engines rated at 3600 rpm
The above power values refer to an engine fitted with air cleaner and standard muffler, after testing and at the environmental conditions of 20°C
and 1 bar.
Max. power tolerance is 5%.
Power decreases by approximately 1% every 100 m di altitude and by 2% every 5°C above 25°C.
Note: Consult KOHLER for power, torque curves and specific consumptions at rates differing from those given above.
