Method for operating direct injection internal combustion engine, involves opening exhaust valve during cylinder induction cycle so previously ejected exhaust gas in exhaust tract is partly sucked back in

The method involves carrying out a charge replacement per working cylinder via cylinder-individual, with suitable control of the inlet and outlet valves. The corresponding exhaust valve is opened during the induction cycle of a cylinder so that a previously ejected exhaust gas in the exhaust tract i...

Beschreibung
Zusammenfassung:	The method involves carrying out a charge replacement per working cylinder via cylinder-individual, with suitable control of the inlet and outlet valves. The corresponding exhaust valve is opened during the induction cycle of a cylinder so that a previously ejected exhaust gas in the exhaust tract is partly sucked back into the cylinder. Die Erfindung betrifft ein Verfahren zum Betrieben einer direkteinspritzenden Brennkraftmaschine, insbesondere eines Ottomotors, wobei ein Ladungswechsel jeweiliger Arbeitszylinder über zylinderindividuelle, entsprechend gesteuerte Einlaß- und Auslaßventile durchgeführt wird. Hierbei wird im Ansaugtakt eines Zylinders das entsprechende Auslaßventil derart geöffnet, daß ein zuvor von diesem Zylinder in den Abgastrakt ausgestoßenes Abgas teilweise in den Zylinder zurück gesaugt wird.
