ABSTRACT:
An apparatus is proposed for regulating the idling rpm of internal combustion engines with externally supplied ignition. The apparatus includes a comparison circuit for set-point and actual rpm, and the idling rpm set-point value can be influenced in accordance with the actual rpm, time, operating voltage, temperature, and other variables as needed. The actual regulation is effected by means of a PID-regulator, whose individual characteristics may be established for processing data as desired, preferably in accordance with the rpm deviation. A limitation regulator furthermore serves to establish the respective maximum and/or minimum limitation of the adjustment member in accordance with operating characteristics.
