Abstract

Ein Brennstoffeinspritzventil (1), insbesondere ein Brennstoffeinspritzventil (1) zum direkten Einspritzen von Brennstoff in einen Brennraum einer Brennkraftmaschine, umfaßt einen Aktor (10) zur Betätigung einer Ventilnadel (3), wobei die Ventilnadel (3) an einem abspritzseitigen Ende einen Ventilschließkörper (4) aufweist, der zusammen mit einer Ventilsitzfläche (6), die an einem Ventilsitzkörper (5) ausgebildet ist, einen Dichtsitz bildet. Brennstoffkanäle (35) sind in einer mit dem Ventilsitzkörper (5) verbundenen oder einstückig ausgebildeten Ventilnadelführung (31) in mehreren Reihen (34) umfänglich in der Ventilnadelführung (31) angeordnet, wobei die Anzahl der Brennstoffkanäle (35) und ihre Lage zueinander so gewählt ist, daß dadurch eine Kennlinie, die den dynamischen Brennstofffluß (qdyn) durch das Brennstoffeinspritzventil (1) in Abhängigkeit von einem Hub (h) der Ventilnadel (3) darstellt, eingestellt wird.
