Abstract

Die Erfindung betrifft ein Verfahren zur Anpassung der Einspritzmenge einer Brennkraftmaschine zur Laufruheregelung, umfassend folgende Verfahrensschritte:

  • a) Erfassung einer Anzahl zylinderindividueller Laufunruhewerte LUz über ein Beobachtungsintervall,
  • b) zylinderindividuelle Sortierung der erfaßten Laufunruhewerte LUz entsprechend ihrer Größe,
  • c) zylinderindividuelle Prüfung des mittleren Laufunruhewertes, ob dieser kleiner, gleich oder größer Null ist und
  • d) Erhöhung der Einspritzmenge, falls der mittlere Laufunruhewert kleiner als Null oder Erniedrigung der Einspritzmenge, falls der mittlere Laufunruhewert größer als Null ist.

    The invention relates to a method for adapting the injection quantity of an internal combustion engine for smooth running control, comprising the following method steps:
  • a) detection of a number of cylinder-specific uneven running values LU z over an observation interval,
  • b) cylinder-specific sorting of the recorded uneven running values LU z according to their size,
  • c) cylinder-specific checking of the mean uneven running value, whether this is less than, equal to or greater than zero, and
  • d) Increase the injection quantity if the mean uneven running value is less than zero or decrease the injection quantity if the mean uneven running value is greater than zero.
