Abstract

Ein Brennstoffeinspritzventil mit integrierter Zündkerze (1) zum direkten Einspritzen von Brennstoff in einen Brennraum (72) einer Brennkraftmaschine und zum Zünden des in den Brennraum (72) eingespritzten Brennstoffs weist einen Ventilkörper (7) auf, der zusammen mit einem Ventilschließkörper (10) einen Dichtsitz bildet. An den Dichtsitz schließt sich eine Abspritzöffnung (12) an, die an einer dem Brennraum (72) zugewandten Stirnfläche (73) des Ventilkörpers (7) ausmündet. Ferner ist ein von dem Ventilkörper (7) isolierter Gehäusekörper (2) und eine mit dem Gehäusekörper (2) verbundene drahtförmige Zündelektrode (70b) vorgesehen. Dabei wird ein Funkenüberschlag zwischen dem Ventilkörper (7) und der Zündelektrode (70b) erzeugt. Die Zündelektrode (70b) und der Ventilkörper (7) sind so geformt, daß der Funkenüberschlag zwischen der dem Brennraum (72) zugewandten Stirnfläche (73) des Ventilkörpers (7) und der Zündelektrode (70b) erfolgt. Die Stirnfläche (73) des Ventilkörpers (7) weist eine Erhöhung (80) mit einer Kante (81) auf, um die Position des Funkenüberschlags an der Stirnfläche (73) des Ventilkörpers (7) bezüglich der Position der Abspritzöffnung (12) reproduzierbar festzulegen.
