ABSTRACT:
Improvements in electromagnetic control injection systems for diesel engines of the pressure-time type where the injection needle is controlled by the discharging then charging of a chamber. Electromagnetic control fuel injection system for diesel engines in which a three-way solenoid valve is placed in the injection holder, the injector needle being controlled during its opening by the pressure drop of the fuel contained in the control space. A disc having a nozzle is used to throttle the passage assuring the pressure drop in the control chamber without throttling the passage during a rise in pressure so that the injector needle begins to move only after the complete movement of the solenoid valve.
