Abstract

Die Kraftstoffeinspritzdüse ist für Dieselmotoren bestimmt und besteht aus einem Düsenkörper (1) mit Düsenkopf (2) und mindestens einem Ausdüskanal (3), wobei im Düsenkörper (1) axial beweglich ein Steuerventil (4) angeordnet und dem Dü­ sen kopf (2), in dem der mindestens eine Ausdüskanal (3) an­ geordnet ist, ein Kraftstoffdesintegrator (5) zugeordnet ist. Um die Kraftstoff-Luftmischung zu verbessern, ist der Desintegrator (5) in bezug auf die Längsmittelachse (6) des mindestens einen Ausdüskanals (3) sich längs oder quer zu dieser Längsmittelachse (6) erstreckend in Distanz vor der Ausmündung des Ausdüskanales im Strahlbereich (7) an­ geordnet. Der Desintegrator (5) ist dabei in Form minde­ stens eines im Strahlbereich (7) an einer Vielzahl von Stel­ len wirksamen Zerstäubers ausgebildet.
