Abstract:
An electronic control arrangement for equalizing torque contributions of different cylinders of an internal combustion engine to the total torque of the engine which can operate in an overrun mode and in a fired mode, the electronic control arrangement comprising:means for providing first quantities (Ka) of a rough running of said engine in said overrun mode and second quantities (Kvi) in said fired mode;means for providing third quantities (Ksi) for a rough-running component based on torsion vibrations;means for forming cylinder-individual fourth quantities (Kki) for said rough running from said first, second and third quantities with said fourth quantities being independent of the rough running in said overrun mode and independent of the rough-running component based on said torsion vibrations; and,means for equalizing said torque contributions on the basis of said fourth quantity.
