Abstract: 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.

Abstract: A method for operating a drive device with an internal combustion engine and an exhaust gas turbocharger associated with an internal combustion engine. The internal combustion engine is connected to an intake tract provided with a throttle valve. A specified ignition point is determined from a rotational speed of an internal combustion engine. At the same time with a target load jump of the internal combustion engine from an actual torque to a target torque with a full opening of the throttle valve by setting a first target ignition point which is later than the specified ignition point, a target reserve is built up and the actual torque is increased at the same time. The target reserve is used prior to reaching the target torque with the actual torque by setting a second target ignition point which is earlier than the first ignition point, and in addition is used to increase the actual torque.
