Abstract

  • 2.1 Die Erfindung betrifft eine Brennkraftmaschine mit einem Kurbelgehäuse, in dem eine Kurbelwelle drehbar gelagert ist, an der zumindest ein einen Kolben tragendes Pleuel angelenkt ist, wobei der Kolben in einem von einem Zylinderkopf unter Bildung eines Arbeitsraums abgedeckten Zylinder bewegbar ist und dem Arbeitsraum über Gaswechseleinrichtungen Frischgas aus einer Frischgasleitung zuführbar sowie Abgas in eine Abgasleitung abführbar ist und wobei die Abgasleitung und die Frischgasleitung über eine luftgekühlte Rückführleitung verbunden sind.
  • 2.2 Erfindungsgemäß wird die Kühlung der Rückführleitung verbessert. Dies wird dadurch erreicht, dass die Rückführleitung in einem Teilbereich als Luft-Abgas-Wärmetauscher 14 ausgebildet direkt an der Brennkraftmaschine angeordnet ist und dass der Luft-Abgas-Wärmetauscher 14 von einem vorhandenen Kühlluftstrom der Brennkraftmaschine durchströmt ist. Durch diese Ausbildung kann ohne einen wesentlichen Mehraufwand und ohne wesentliche Änderungen an der Brennkraftmaschine eine intensive Kühlung erreicht werden.
