Abstract (en)
[origin: WO2007141096A1] In an internal combustion engine, at least one torsion value (dn/dt) that characterizes the rotary movement of a crankshaft is registered individually for each cylinder. It is recommended that, in an operating state in which differences and/or fluctuations in the torsion value (dn/dt_current) essentially depend on a combustion system, the moment (AB_St) of fuel injection should be individually adapted for each cylinder, to reduce said differences and/or fluctuations (52).
