Title: Injection timing nozzle

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