Die Erfindung geht aus von einer Vorrichtung bzw. einem Verfahren zum Einspritzen von Kraftstoff in einen Brennraum einer Brennkraftmaschine nach der Gattung der unabhängigen Patentansprüche. Aus der

Auch die
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorrichtung bzw. das erfindungsgemäße Verfahren mit den Merkmalen der unabhängigen Patentansprüche haben demgegenüber den Vorteil, dass Zündaussetzer zuverlässig vermieden werden können. Es kann so der Betrieb einer direkteinspritzenden Otto-Brennkraftmaschine deutlich verbessert werden.The inventive device or the inventive method with the features of the independent claims have the advantage that misfiring can be reliably avoided. It can be significantly improved so the operation of a direct-injection gasoline engine.
Vorteilhafte Weiterbildungen und Verbesserungen ergeben sich durch die Merkmale der abhängigen Patentansprüche. Besonders einfach können die Einspritzparameter Einspritzdruck, Hub einer Einspritznadel oder die Einspritzzeit beeinflusst werden. Die erfindungsgemäße Vorrichtung bzw. Verfahren eignen sich besonders gut, wenn durch das Einspritzventil in dem Brennraum ein Haupteinspritzstrahl und ein Rezirkulationsgebiet gebildet werden. Im Haupteinspritzstrahl führt der Kraftstoff eine gerichtete Bewegung aus, während im Rezirkulationsgebiet ein besonders zündfähiges Luft-Kraftstoff-Gemisch vorliegt. Durch die Beeinflussung der Einspritzparameter kann die Lage des Rezirkulationsgebietes relativ zur Zündkerze beeinflusst werden. Besonders vorteilhaft ist die Erkennung der Entzündung des eingespritzten Kraftstoffes durch einen Sensors, der direkt eine Messung im Brennraum vornimmt. Dazu sind beispielsweise Brennraumdrucksensoren oder Ionenstromsensoren geeignet. Alternativ kann auch eine Auswertung der Drehzahl der Brennkraftmaschine erfolgen, wobei das Ausbleiben einer Zündung durch einen Drehzahleinbruch erkannt wird. Bei dieser Art der Auswertung ist als Alternative zur Veränderung der Einspritzparameter auch eine Veränderung der Einspritzmenge als mögliche Ursache für den Drehzahleinbruch zu untersuchen.Advantageous developments and improvements emerge from the features of the dependent claims. The injection parameters injection pressure, stroke of an injection needle or the injection time can be influenced particularly easily. The device or method according to the invention are particularly well suited if a main injection jet and a recirculation zone are formed by the injection valve in the combustion chamber. In the main injection jet, the fuel executes a directed movement, while in the recirculation area a particularly ignitable air-fuel mixture is present. By influencing the injection parameters, the position of the recirculation area can be influenced relative to the spark plug. Particularly advantageous is the detection of the ignition of the injected fuel by a sensor which makes a direct measurement in the combustion chamber. For example, combustion chamber pressure sensors or ion current sensors are suitable for this purpose. Alternatively, an evaluation of the speed of the internal combustion engine can take place, wherein the absence of ignition is detected by a speed drop. In this type of evaluation, as an alternative to changing the injection parameters, it is also necessary to investigate a change in the injection quantity as a possible cause of the speed drop.

Alternativ gibt es noch ein weiteres Verfahren zur Bestimmung von Verbrennungsaussetzern, welches keine zusätzlichen Sensoren wie Brennraumdrucksensor
Alternativ kann natürlich auch versucht werden, zunächst die Einspritzparameter zu beeinflussen, und nur, wenn dies keinen Erfolg zeigt, dass dann die Einspritzmenge beeinflusst wird. Weiterhin kann der Versuch, einen Drehzahleinbruch durch eine Änderung der eingespritzten Menge zu beheben, auch solange fortgesetzt werden, bis eine zulässige Verstellgrenze der Einspritzmenge überschritten wird.Alternatively, of course, an attempt can also be made to first influence the injection parameters, and only if this does not prove successful, that the injection quantity is then influenced. Furthermore, the attempt to eliminate a speed drop by a change in the injected quantity can also be continued until an allowable adjustment limit of the injection quantity is exceeded.
