Abstract

Es wird ein Verfahren und eine Vorrichtung zur Einstellung des Leerlaufs einer Brennkraftmaschine vorgeschlagen, wobei bei heißer Brennkraftmaschine die Leerlaufdrehzahl erhöht wird. Dabei liegt eine heiße Brennkraftmaschine dann vor, wenn die Motortemperatur und die Ansauglufttemperatur vorbestimmte Schwellwerte überschreiten und die Motordrehzahl eine vorgegebene Zeit lang oberhalb einer Grenzdrehzahl liegt.
