Fuel injection valve for internal-combustion engine, has volume between front surface of valve closing section and front surface, and coating with non-stick effect for combustion residues provided at front surfaces that limit volume

摘要

The valve has an excitable actuator operating a valve closing section (28) that forms a sealing seat with a valve seat surface (27) at a valve seat unit (26). Discharge openings (32) are designed downstream of the surface. A volume (30) lies between a front surface (52) of the section and a front surface (53). A coating (50) with non-stick effect for combustion residues is provided at the front surfaces that limit the volume.
