Abstract (en)
[origin: WO9115673A1] Described is a fuel injection valve for fuel injection units in internal-combustion engines, the valve having a hollow nozzle body (10) with a fuel-filled chamber (11) and a nozzle jet (13) for the fuel to emerge. Inside the nozzle body (10) is a valve seat (14) which works in conjunction with a valve closure element (16). To ensure a high degree of atomization or electrostatic charging of the fuel emerging from the jet aperture (13), the valve is fitted with two electrodes (21, 22) under high tension, at least one of the electrodes being made of a material suitable for the field emission of charge carriers. One electrode (21 or 22) is mounted on the valve closure member (16) and the other electrode (22 or 21) on the nozzle body (10) in such a way that an electric field extending through the fuel stream is formed directly in front of or behind the valve seat (14).
