Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben einer Brennkraftmaschine nach einem Sechstakt-Verfahren mit folgender Taktfolge:
  • 1.Takt (I): Ansaugen von Luft in einen Brennraum,
  • 2. Takt (II): Verdichten der Luft und Einspritzen (3a) einer ersten Teilmenge von Otto-Kraftstoff in den Brennraum,
  • 3. Takt (III): Erster Arbeitshub mit vorangegangener erster Zündung (5) des Gemisches, wobei die Zündung (5) durch eine Zündeinrichtung eingeleitet wird,
  • 4. Takt (IV): Neuverdichtung des Brennrauminhaltes,
  • 5. Takt (V): Zweiter Arbeitshub mit vorangegangener zweiter Zündung (6) des im Brennraum befindlichen Kraftstoff-Luftgemisches,
  • 6. Takt (VI): Ausschieben der Abgase aus dem Brennraum,
wobei vor der zweiten Zündung (6) eine Einspritzung (3b) einer zweiten Teilmenge von Otto-Kraftstoff erfolgt.
Um bei einer Brennkraftmaschine möglichst geringen Kraftstoffverbrauch und niedrige Emissionen zu erzielen, wird vorgeschlagen, dass die Einspritzung (3b) der zweiten Teilmenge von Otto-Kraftstoff im dritten Takt (III), vorzugsweise in der zweiten Hälfte des dritten Taktes (III), erfolgt, dass im Brennraum vor der zweiten Zündung (6) ein zumindest annähernd homogenes Kraftstoff-Luftgemisch gebildet wird und dass die zweite Zündung (6) durch Kompressionszündung dieses homogenen Kraftstoff-Luftgemisches erfolgt.
