  • Patent number: 5947091
    Abstract: A fuel injection valve for an internal combustion engine includes a metering injection valve and a fuel vaporizer that is arranged upstream from an outlet spray orifice of the injection valve (10) on the intake end and has a vaporizer area with at least one assigned electric heating element. To assure in particular that the fuel vaporizer guarantees very good fuel processing in all heating states, i.e., in heating operation for complete or partial vaporization and in the unheated state, the vaporizer area that accommodates at least one heating element is closed at the outlet end by an outlet valve.

  • Patent number: 5707012
    Abstract: An atomizing sieve of a fuel injection valve having a dish-like concavely cambered form is provided downstream of at least one spray orifice of the fuel injection valve, as seen in the direction of flow of fuel. The atomizing sieve is cast with an outer circumferential region in a protective cap provided at the downstream end of the fuel injection valve. For protection against mechanical effects, protective prongs of the protective cap project further downstream than the lowest region of the atomizing sieve. When the fuel is being injected, a part quantity collects in this lowest region and represents a comparatively static liquid quantity which new fuel then strikes. This arrangement allows an ideal break-up of the fuel into very small droplets. The atomizing sieve also forms a protective shield against icing-up, plugging and settlement of chemical substances within the fuel injection valve.
