ABSTRACT:
The invention provides a process and an apparatus for controlling the engine torque of an internal-combustion engine. A dynamic desired torque component is determined from a demanded desired engine torque, and is used to determine a corresponding displacement of the ignition point or of the injection start, while a remaining quasi-static desired torque component is regulated by a corresponding adjustment of the air flow rate or of the fuel injection duration.
