N (80/1269/EEC - ISO 1585) AUTOMOTIVE RATING : Intermittent operation with variable speed and variable load.
NB (ISO 3046 - 1 IFN) RATING WITH NO OWERLOAD CAPABILITY: continuos ligth duty operation with constant speed and variable
load.
NA (ISO 3046 - 1 ICXN) CONTINUOS RATING WITH OVERLOAD CAPABILITY: continuos heavy duty with constant speed and
constant load.
Mt-N Torque at N power.
C Specic 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 tted with air cleaner and standard mufer, 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.
