Abstract

Fuel injection nozzle for delivering fuel directly to a combustión space of an internal combustión engine, said nozzle comprising a valve member movable within a hole, a seat in the bore, the valve member being profiled with a view to its cooperation with the seat to control the flow of the fuel passing through an outlet orifice, elastic means acting to urge the valve member into contact with the seat, a defined surface on the valve member and against which the fuel can be actuated under pressure to lift the valve member from its seat, and a piezoelectric crystal generator mounted on a body part of the nozzle unit, said generator being positioned in order to be subjected to impact directly by the valve member or indirectly by a member moved by the valve member when separating the valve member from the asient or.
