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.

摘要: A fuel delivery system for an internal combustion engine having an intake air metering device, leading to individual combustion chambers several fuel injection valves, each of which is assigned to one combustion chamber, and a central fuel vaporizer to which fuel can be supplied by a fuel metering device. To reduce pollutant emissions during the warm-up phase of the internal combustion engine after start-up, fuel vapor generated in the fuel vaporizer can be added to the intake air for the combustion chambers downstream from the intake air metering device.

摘要: A fuel injection valve prevents capillary flow by the provision of controlled pressure compensation. In the region of axial extension of the magnet coil, at least one radially extending transverse hole is introduced into the valve housing and this hole is covered by a diaphragm which surrounds the valve housing in the form of a ring. The diaphragm allows pressure compensation without the risk that moisture will penetrate into the interior of the valve and prevents negative capillary flows. The fuel injection valve is suitable, in particular, for use in fuel injection systems of mixture-compressing applied-ignition internal combustion engines.

摘要: The invention provides sealing ring formed by a ring inner part and a bulge, the bulge extending radially outward at a right angle to a longitudinal axis of the ring so that a T-shaped cross section of the sealing ring is produced. The slightly conically extending inner surfaces of the sealing ring are pressed radially outward upon assembly so that a long guide area of the sealing ring on the contact pin is created which completely precludes any tilting of the sealing ring and increases the axial sealing. The sealing ring is particularly suitable for use in electromagnetically actuatable fuel injection valves.
