Abstract
The speed of an internal combustion engine is monitored during the entry thereof into low-idle speed operation. The engine speed can thereby be slaved to a predetermined reference point value. When a predetermined engine condition occurs which is considered to require the engine to switch to idling speed, the set speed of the engine is forced downwardly according to a predetermined time law. The set speed thereby shifts towards the predetermine idling speed.
