Abstract

A fuel injection device having an injection valve on which an atomizing grid is arranged. The disk-shaped atomizing grid is arranged downstream of a valve seat face and is equipped with an atomizing structure which at least partially possesses variations in cross section in the axial direction, over the thickness of the atomizing grid. As a result of the geometry of the atomizing grid, the fuel is atomized particularly finely into very small droplets without auxiliary energy. The fuel injection device is particularly suitable for use in fuel injection systems of mixture-compressing spark-ignition internal combustion engines.
