摘要:
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.
