Abstract

In an internal combustion engine, at least one rotation variable characterizing the rotational movement of a crankshaft is ascertained cylinder-specifically. It is provided that, in an operating state in which differences and/or fluctuations of the rotation variable are basically a function of a combustion position, the instant of a fuel injection is adapted cylinder-specifically in order to reduce the differences and or fluctuations.
