Abstract

  • 2.1
    Ein bekannter Brennluftansaugrohrabschnitt weist den Nachteil auf, daß eine extreme Verschmutzung eines Abgasrückführsteuerventils auftreten kann.
  • 2.2
    Hiergegen weist der neue Brennluftansaugrohrabschnitt die Merkmale auf, daß der Ansaugrohrabschnitt (1) als Gußgehäuse (7) ausgebildet ist und Aufnahmeausnehmungen (8, 9) aufweist, in die ein Abgasrückführeinleitungseinsatz (10) und ein Abgasrückführsteuerventileinsatz (11) eingesetzt und mittels Paßsitzabschnitten (12, 13) in den Aufnahmeausnehmungen (8, 9) gehalten sind.
  • 2.3
    Hierdurch ist eine gegen Schmutz geschützte Ausführung erreicht worden.
