ABSTRACT:
The invention is directed to a method and an arrangement for controlling the torque outputted by an internal combustion engine while deactivating individual cylinders. A desired value for the torque outputted is obtained by suppressing and resuming the metering of fuel to at least one cylinder as well as by adjusting the ignition angle. The deactivation and reactivation of the cylinders and the adjustment of the ignition angle are synchronized.
