Abstract

Die Erfindung betrifft ein Verfahren (61) zum Betreiben einer Brennkraftmaschine (11) mit mehreren Brennräumen (15), wobei mindestens einem Brennraum (15) ein Einspritzventil (13) zum Einspritzen von Kraftstoff (mf) in den Brennraum (15) zugeordnet ist, wobei für mindestens einen Brennraum (15) eine brennraumindividuelle Luftzahl (λ) eingeregelt wird und/oder für mindestens einen Brennraum (15) ein brennraumindividuelles Drehmoment (M) ermittelt wird. Um ein Verfahren (61) zum Betreiben einer Brennkraftmaschine (11) anzugeben, und wobei Fehladaptationen möglichst weitgehend vermieden werden sollen. Es soll für mindestens ein Einspritzventil (13) eine Ansteuerdauer (TA) des Einspritzventils (15) derart durch Erfassen oder Ermitteln einer Ventilöffhungsdauer (T) des Einspritzventils (15) adaptiert (A) werden, dass Toleranzen des Einspritzventils (15) bezüglich eines Zusammenhangs zwischen der Ansteuerdauer (TA) und der Ventilöffhungsdauer (T) zumindest im Wesentlichen ausgeglichen werden.
