Abstract
An electronically controlled fuel injection device includes a plunger pump, a circulation passage which circulates fuel that has been pressurized in the initial stage of a pressure-feeding stroke, a valve body which blocks the circulation passage in the later stage of the pressure-feeding stroke, an inlet orifice nozzle which allows the passage of fuel whose pressure has been increased in the later stage of the pressure-feeding stroke, an outlet orifice nozzle which is used to circulate some of the fuel that has passed through the inlet orifice nozzle back into the fuel tank, an injection nozzle which injects an amount of fuel equal to the difference between the fuel that has passed through the inlet orifice nozzle and the fuel that has passed through the outlet orifice nozzle, and a control arrangement for controlling the plunger pump in response to the cycle of the engine.
