ABSTRACT:
A needle position indicator is positioned within the interior of a fuel injector nozzle holder which includes a needle having upper and lower ends, a needle seat which engages the lower end of the needle, a chamber having an upper end and a lower end through which the upper end of the needle extends, and a spring positioned within the chamber for exerting a force against the upper end of the chamber and against the upper end of the needle to bias the needle against the needle seat. The needle position indicator includes a magnet which is positioned within the cavity to generate a magnetic field within the cavity and a detector which is positioned within the cavity to detect changes in the strength of the magnetic field within the cavity caused by relative displacements of the upper portion of the needle within the cavity.
