Abstract (en)

[origin: WO2007012555A1] A method for operating an internal combustion engine (10) is proposed, in which method a first rotational characteristic variable (wl) is measured at a first end (24) of a shaft (12) of the internal combustion engine (10) and cylinder-individual rotational characteristic variables (MFl, wZl, KWW_Z1, MRl, ...., MFn, wZn, KWW_Zn, MRn) are determined using the first rotational characteristic variable (wl). The method is distinguished by the fact that a second rotational characteristic variable (w2) is measured at a second end (26) of the shaft (12) and the cylinder-individual rotational characteristic variables (MFl, wZl, KWW_Z1, MRl, ...., MFn, wZn, KWW Zn, MRn) are determined using the first rotational characteristic variable (wl) and the second rotational characteristic variable (w2). Furthermore, a control unit (22) is proposed which controls the method.
