Abstract
Fuel injector nozzle holders typically include a needle which is coupled within the nozzle holder and displaceable between open and closed positions. The nozzle holder also includes a chamber and a spring positioned within the chamber and coupled to the needle for biasing the needle toward the closed position. Prior art fuel injector nozzle holders can readily be modified to include a passageway for establishing communication with the chamber from a location external to the nozzle holder. This passageway may be dimensioned to permit an external sensing device which is capable of detecting displacements of the needle when positioned in proximity thereto to be inserted through the passageway into the chamber. A sensor holder is positioned within the chamber and aligned with the passageway to guide the sensor into a predetermined position with respect to the needle and to maintain the sensor in a fixed position.
