ABSTRACT:
The invention provides a method and apparatus for engine torque regulation in which, for rapid engine torque reduction, fuel injection is cut out using a cutout pattern that can be selected from a predetermined set of cutout patterns, as a function of the deviation of the engine torque. According to the invention, an engine-torque-reducing throttle position intervention is also implemented parallel to the fuel injection cutout. The difference in torque between a load-indicated actual engine torque (derived from an engine air volume measurement) and the required set engine torque can be regulated with an appropriate reduction of the degree of injection cutout in stages.
