Abstract
Die Erfindung betrifft ein Verfahren zur Adaption eines in einem Hochdruckspeicher eines Kraftstoffzumeßsystems einer direkt einspritzenden Brennkraftmaschine herrschenden maximalen Einspritzdrucks, wobei von dem Hochdruckspeicher mehrere Betriebsgrößen abhängig steuerbare Einspritzventile zum Zumessen von Kraftstoff aus dem Hochdruckspeicher in Brennräume der Brennkraftmaschine abzweigen. Um den maximalen Einspritzdruck in dem Hochdruckspeicher derart einzustellen, dass einerseits die Ressourcen des Kraftstoffzumeßsystems optimal ausgenutzt werden und andererseits aber noch alle Einspritzventile mit Sicherheit öffnen, werden die nachfolgenden Schritte vorgeschlagen:
- Einstellen eines bestimmten Einspritzdrucks als Anfangsdruck;
- Erhöhen des Einspritzdrucks ausgehend von dem Anfangsdruck bei gleichzeitigem Überprüfen, ob die Einspritzventile öffnen;
- Beenden der Erhöhung des Einspritzdrucks, sobald mindestens eines der Einspritzventile nicht mehr öffnet;
- Verringern des Einspritzdrucks um einen vorgegebenen Betrag; und
- Heranziehen des verringerten Einspritzdrucks als maximalen Einspritzdruck des Hochdruckspeichers.
- Setting a certain injection pressure as the initial pressure;
- Increasing the injection pressure from the initial pressure while checking whether the injectors open;
- Ceasing to increase the injection pressure as soon as at least one of the injection valves no longer opens;
- Reducing the injection pressure by a predetermined amount; and
- Using the reduced injection pressure as the maximum injection pressure of the high-pressure accumulator.
