IGNITION SYSTEM FOR USE WITH FUEL INJECTED- SPARK IGNITED INTERNAL COMBUSTION ENGINES Abstract of the Disclosure: The valve seat and cooperating movable valve member of each fuel injector of an associated fuel injected- spark ignited internal combustion engine are connected in series with a resistor across a direct current potential source. The valve seat and movable valve member provide a pair of normally closed electrical contacts which are opera- ted to the electrical circuit open condition upon the initiation of actuation of the movable valve member to inject fuel. Upon each operation of these normally closed electrical contacts to the electrical circuit open condition, an electrical signal is produced thereacross and applied to an associated electronic ignition system which, in response thereto, produces an ignition spark-creating potential. Each ignition spark initiating potential is directed to the spark plug of the engine cylinder into which fuel is being injected by the actuated fuel injector.
