To avoid a sudden change in torque when switching over the valve lift of discretely adjustable inlet valves, the valve lift is firstly only adjusted for a section of cylinders, while the valve lift for the remaining section of cylinders is switched over after a delay. Therefore with each valve lift adjustment, only a slight change in torque has to be compensated by means of a corresponding change in the efficiency of the cylinders.
