Abstract

An apparatus 14 for adapting the characteristic of an idling adjuster has a release means 15 which allows adaptation only when the sign of a speed control deviation .DELTA.n corresponds to the sign of an air-quantity control deviation .DELTA.Q. This guarantees that the adaptation cannot counteract the speed control either as a result of still insufficient adaptation or by shunt signals from the air-quantity meter 11.
