An outwardly opening poppet valve type, fuel injection nozzle is provided with a part or parts thereof electrically insulated relative to the nozzle housing whereby, when the injector poppet valve is closed an electrical circuit can be completed through the injector poppet valve and housing and, when the injector poppet valve is moved to an open position, the continuity of this electrical circuit would be broken. By connecting an electrical continuity tester to this electrical circuit the opening and closing of the injector poppet valve can be detected and can be used to set the timing of a diesel engine.
