ABSTRACT:
A fuel injection apparatus has an accumulator, a booster, a nozzle, a hydraulic circuit, a hydraulic pressure valve and a control valve. At least one of a transmission path, which is connected to the hydraulic circuit, and the hydraulic piston is configured to generate a delay in an operation of the nozzle or the booster that is driven by one of fuel pressure in the control chamber and fuel pressure in the back pressure chamber that is directly controlled by the control valve, against an operation of the booster or the nozzle that is driven by the other of the fuel pressure in the back pressure chamber and the fuel pressure in the control pressure indirectly controlled by the hydraulic pressure valve.
