ABSTRACT:
A fuel injection apparatus includes a pumping plunger operated in synchronism with an engine and a pumping cylinder into which the pumping plunger is inserted. A pump chamber is defined by the pumping plunger and pumping cylinder. An injection plunger operated by a hydraulic pressure in the pump chamber is inserted into an injection cylinder leading to the pump chamber to define an injection pump chamber. Fuel supplied from a fuel source is, after adjusted to a predetermined amount, supplied to the injection pump chamber. A fuel return passage is connected to the pump chamber and a blocking mechanism is disposed on the fuel return passage to block the passage at an optimal fuel injection time of an engine. The fuel in the pump chamber is discharged by a discharge mechanism at the fuel injection finishing time.
