Abstract

Ein Brennstoffeinspritzsystem weist zumindest ein Brennstoffeinspritzventil (3), einen Zuteilungsabschnitt (1) und einen Niederhalteabschnitt (2) auf. Der Zuteilungsabschnitt (1) leitet dem Brennstoffeinspritzventil (3) Brennstoff zu. Der Niederhalteabschnitt (2) hält das Brennstoffeinspritzventil (3) elastisch nieder. Der Niederhalteabschnitt (3) stützt sich am Zuteilungsabschnitt (1) ab.
