Abstract (en)

[origin: DE19546554C1] A procedure and a device for controlling the torque of an IC engine use the limiting of the fuel injection for rapid torque reduction according to a particular pattern. In parallel with this, the throttle flap is controlled, through which the load-indicated torque is adjusted to the delivered torque. The criterion for the particular pattern is the difference between load-indicated and delivered torque.
