Abstract
A method and apparatus control the power to be delivered by a mixture-compressing internal combustion engine which, during normal operation of the internal combustion engine, is adjusted by matching the fuel injection quantity to the induced air mass flow corresponding to the current load demand and controllable by a setting element. So that control of the internal combustion engine power to be delivered remains possible (emergency driving function) in the case of an impairment of the function of the setting element for controlling the induced air mass flow but, at the same time, so that a reduction in the volumetric efficiency of the internal combustion engine is not to be expected in normal operation, the internal combustion engine power is adjusted to the value corresponding to the current load demand during the period of the functional fault exclusively by interventions in the mixture composition and/or by interventions in the ignition and/or by controlled interruption of the fuel delivery to at least one cylinder (i.e. cylinder shut-down).
