Method for controlling internal-combustion engine, involves determining cylinder-individual characteristic by frequency-selective filtered rotational speed signal

摘要

The method involves determining a cylinder-individual characteristic by a frequency-selective filtered rotational speed signal. A correcting variable is changed with two cylinders of the internal-combustion engine. A quantity error of a cylinder is detected by the change of the cylinder-individual characteristic. An independent claim is included for a device for controlling an internal-combustion engine.
