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.

[ What is claimed is:] [1.] Method for controlling the torque of an internal combustion engine while deactivating a single cylinder, the method including adjusting the ignition angle and adjusting the metering of fuel to the cylinder, the engine having cylinders which assume a first state in which fuel is supplied thereto and a second state in which no fuel is supplied thereto, the method comprising the steps of:reading a pregiven desired value of torque (Mmotdes) for the torque of said engine;determining a number (X) of cylinders which assume said second state and determining an adjustment of said ignition angle (ZWdes) dependent upon said pregiven desired value of torque (Mmotdes);outputting injection pulses in dependence upon the determined number (X) of said cylinders which assume said second state;determining whether at least one cylinder changes its state relative to a previous operating cycle;outputting an ignition angle on the basis of the determined ignition angle (ZWdes) for any one of said cylinders when no cylinder changes its state; and,outputting an ignition angle on the basis of the determined ignition angle (ZWdes) only for the at least one cylinder which changes its state when at least one cylinder changes its state compared to a previous operating cycle.
