A fuel injector for the direct injection of fuel into the combustion chamber of a mixture-compressing internal combustion engine having external ignition includes a valve housing formed by a nozzle body, and a seal which seals the fuel injector from a cylinder head of the internal combustion engine. The seal has a sleeve-type design with a structured cross section and extends across the axial length of the nozzle body.

Fuel injector nozzle seal

In a fuel injector for a direct-injection internal combustion engine comprising an injection nozzle, on the circumference of which a plurality of injection orifices are arranged so as to line up with one another, to form an orifice arrangement for the formation of an essentially conical fuel cloud from the individual fuel jets of the respective injection orifices the nozzle orifice locations are displaced so as to form a recess in the jet envelope in an area where a spark plug is located into which the spark plug extends so as to safely ignite the fuel cloud without getting wetted by the fuel.
