Abstract

Es werden ein Verfahren und eine Vorrichtung zur Überwachung eines Kraftstoffzumeßsystems einer Brennkraftmaschine beschrieben. Der Kraftstoff wird mittels einer Pumpe in einen Speicher gefördert. Von dort ist er mittels betriebskenngrößen abhängig steuerbarer Injektoren den Brennräumen der Brennkraftmaschine zumeßbar. Ein Sensor stellt ein Drucksignal bereit, das den Druck im Speicher charakterisiert. Ausgehend von einer Änderung des Drucksignals bei einer Änderung einer den Druck bestimmenden Größe wird ein fehlerhaftes Drucksignal erkannt.
