Abstract
A fuel injection valve which serves to inject fuel into the intake tube of internal combustion engines. The fuel injection valve includes a valve seat disposed in a valve housing, downstream of which valve seat a preparation bore is provided in a nozzle body, which terminates in the fuel flow direction at a sharp-edged nozzle body end embodied by a first conical zone. The first conical zone protrudes into a cylindrical guide conduit of a front attachment. The cylindrical guide conduit discharges via a first guide conduit end into a conically widening guide conduit, which leads via a second guide conduit end into the intake tube of an internal combustion engine.
