Emission control
The system provides a warning if there are faults
on the SCR system or if the level of reductant in
the reductant tank is too low. In the case of some
faults, for example if doser cooling is not work-
ing, the torque is reduced.
Reaction at low reductant level
The engine resumes normal torque after reduct-
ant has been filled to a level of at least 20%.
600-750 rpm Low idling. Engine idling is controlled by the engine management system.
Low idling up to 2,100 rpm Engine operating speed range. Controlled by the engine management sys-
tem.
2,100-2,600 rpm Unsuitable operating speed, but a slightly higher engine speed than the nor-
mal maximum operating speed may occur when load is low or negative.
2,600-3,000 rpm Prohibited engine speed.
