Abstract
An arrangement for regulating the idling rotational speed of an internal combustion engine includes a comparison stage which compares the actual and the desired rotational speed, an idling operation filling regulation device connected to the output of the comparison stage, including at least a proportional region, and controlling an electrically manipulated adjustment member for the adjustment of the amount of intake air in the idling operation position of the throttling damper, as well as an arrangement for the recognition of a jerky operation of the engine. The recognition arrangement is so constructed that it concludes from the frequency and intensity of periodically occurring rotational speed oscillations that a tendency to operate in a jerky manner is present and issues a signal which so influences the amplification degree of the proportional region of the regulating device for the idling operation regulation that a manipulated variable from the proportional region is maintained during the increasing rotational speed and asymetrically substantially at the maximum achieved value or preferably is caused to gradually decrease with a selectable time constant, while being caused to…
