Abstract: A fuel injector for an internal combustion engine which includes a housing having a flange for mounting the fuel injector to a cylinder head, a pump jet and at least one electrical component internal of the housing, a pair of electrical connector leads for the electrical component, an aperture extending through the flange, and a portion of the electrical connector leads extending from internally of the housing and terminating in the aperture, thereby permitting the pair of electrical connector leads to be connected with another pair of electrical connector leads in the aperture. The ends of the electrical connector leads are preferably provided with electrical connecting elements secured in the aperture and the other pair of electrical connector leads may be provided in the form of an extension or plug adapted to engage the electrical connecting elements in the aperture.

Abstract: In a fuel injection nozzle for an internal combustion engine, a valve needle and a valve needle spring are provided, in which the valve needle can be opened against the force of the valve needle spring (6). In the valve needle spring chamber (8) a displacer piston (7) is arranged so as to overlap the valve needle spring (6), which piston clears a displacing volume after a pre-injection so that the pre-injection is separated from the main injection.
