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.The invention relates to a method for operating an internal combustion engine according to a six-stroke method with the following cycle sequence:
  • 1st cycle (I): intake of air into a combustion chamber,
  • 2nd cycle (II): compressing the air and injecting (3a) a first subset of gasoline into the combustion chamber,
  • 3rd cycle (III): first working stroke with preceding first ignition (5) of the mixture, the ignition (5) being initiated by an ignition device,
  • 4th cycle (IV): re-compression of the combustion chamber contents,
  • 5th stroke (V): second working stroke with preceding second ignition (6) of the fuel-air mixture located in the combustion chamber,
  • 6th cycle (VI): pushing the exhaust gases out of the combustion chamber,
wherein before the second ignition (6) an injection (3b) of a second subset of gasoline takes place.

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.In order to minimize fuel consumption and To achieve low emissions, it is proposed that the injection (3b) the second subset of petrol in the third stroke (III), preferably in the second half of the third cycle (III), that takes place in the combustion chamber before second ignition (6) an at least approximately homogeneous fuel-air mixture is formed and that the second ignition (6) by compression ignition this homogeneous fuel-air mixture takes place.
