  "textContent": "An internal combustion engine with a plurality of cylinders is a drive device in which the drive torque available can be reduced. The ignition timing which is set at the internal combustion engine is adjusted in the retarded direction starting from an initial ignition timing until the ignition timing corresponds to a threshold ignition timing. To reduce the drive torque further, at least one cylinder, among the plurality of cylinders, is deactivated by suspending fuel injection into the cylinder, and the remaining cylinder(s) continue to be operated with fuel injection using the ignition timing. The remaining cylinders of the internal combustion engine which continue to be operated are supplied with a quantity of fuel which is larger in comparison with an initial quantity of fuel present before the cylinder deactivation, to set a substoichiometric fuel/oxygen ratio.",
