Abstract
An ignition initiating signal is developed from the fuel injection nozzle valve of an internal combustion engine. The valve is actuated by fuel pressure which creates an insulating layer at the valve so that when the valve is unseated an electrical circuit is broken to create the ignition initiating signal. And, electrical circuit means are included which limit the voltage applied and the current flow at the valve seat in order to avoid breakdown of the fuel insulating layer and pitting of the valve seat.
