Abstract

Vorgestellt wird ein Verfahren zur Ausgabe von Einspritzimpulsbreiten bei einem Verbrennungsmotor (10) mit direkter Einspritzung von Kraftstoff in wenigstens einen Brennraum (12), wobei der Verbrennungsmotor (10) in verschiedenen Betriebsarten (70, 72) mit verschiedenen Mustern (74, 76, 78, 80, 82) von Einspritztypen betrieben werden kann und wobei jedes Muster (74, 76, 78, 80, 82) einem Arbeitszyklus des Verbrennungsmotors (12) zugeordnet ist. Das Verfahren zeichnet sich dadurch aus, dass wenigstens einer Betriebsart (70; 72) mehrere Muster (74, 76, 78; 80, 82) von Einspritztypen zugeordnet sind. Darüber hinaus wird ein Steuergerät (26) zur Steuerung des Verfahrens vorgestellt.Disclosed is a method of outputting injection pulse widths in an internal combustion engine (10) with direct injection of fuel into at least one combustion chamber (12), the internal combustion engine (10) operating in different modes (70, 72) with different patterns (74, 76, 78 , 80, 82) of injection types and wherein each pattern (74, 76, 78, 80, 82) is associated with a duty cycle of the internal combustion engine (12). The method is characterized in that at least one operating mode (70, 72) is assigned a plurality of patterns (74, 76, 78, 80, 82) of injection types. In addition, a control unit (26) for controlling the method is presented.
