Abstract

PURPOSE: To detect ignition timing correctly by providing simply built-up contraction and pressure detector in a fuel recirculation passage of a fuel injecton valve.
CONSTITUTION: Contriction 10 is formed in a recirculation passage 9 of a fuel injection valve 1 and a pressure detector 11 is provided upstream it. Fuel from the injection pump is supplied through a passage 3 into a cylindrical room in a nozzle tip 2 of the fuel injection valve 1. When a valve-body-combined push rod 6 on the nozzle tip 2 is forced up against a spring 4, fuel in a sealed room 7 is pressed to rise the pressure upstream the contriction 10, which is detected by the pressure detector 11. The pressure detector 11 makes correct detection of an injection timing in terms of fuel variation in pressure following the movement of the valve body.
