- the adaptation ranges are to be defined such that they do not overlap for the adaptation values fra_PFI, fra_DI and the adaptation value offsets ora_PFI, ora_DI.
- the adaptation value offsets ora_DI, ora_PFI to the intake manifold injection quantity r K intake pipe or the direct injection quantity r K tribe may be taken into account after multiplication by the corresponding distribution measures, as shown in the functional diagram of FIG. It can be seen that essentially the arrangements of the blocks 25, 24 and 28, 29 are interchanged for this purpose.
