Abstract

In order to achieve at least a short-term reduction of the torque of an internal combustion engine, which comprises a range as widely adjustable as possible, causes a slight as possible thermal stress on the components of the attached exhaust gas system and allows for a reduction of the fuel consumption, it is proposed that in addition to the cut off of the fuel-delivery control phase of a cylinder, an intake valve associated with the cylinder is cut off.
