ABSTRACT:
Arrangement for stabilizing the idling speed of an internal combustion engine. In an arrangement for early setting of the ignition angle having a microcomputer, a timer is provided that is set to a run-down time (t) that is a rated time that the crankshaft needs in order to turn from an arbitrarily selected basic angle (GW) to an associated idling angle (LW) for a rated idling speed, this idling angle being the ignition angle at the rated idling speed. The timer is started when the angular position of the crankshaft has reached the basic angle (GW). The angular position of the crankshaft following the run-down time (t) is a premature angle (FW) that is used as the ignition angle and that occurs earlier and earlier for dropping idling speed. The arrangement guarantees an immediate early setting of the ignition angle for decreasing idling speed without direct involvement of the microcomputer.
