Abstract

The engine fuel injection nozzle has a body clamped by a capnut against a holder, and an incandescent body downstream of the nozzle body, forming a passage for the jets and connected to an electrical conductor. This is in the form of a bush, insulated in an annular gap between nozzle body and capnut, and has a wall section protruding into an aperture in the nut wall. The bush bears against the tongue of a contact ring fixed to an insulating sleeve on the outside of the nut. An insulator (98) fits in the aperture (96) in the nut wall and secures a metal contact (100), bearing on the outside against the tongue and on the inside against a section of the conductor (72) leading to the incandescent body.
