Abstract:
Disclosed herein is a two-stage fuel injection valve for a diesel engine. The valve includes a fuel valve block (110) having therein a passage (1701) into which fuel is supplied; a nozzle (140) having a low pressure nozzle hole (160) and a high pressure nozzle hole (161); a needle valve (130) differentially opening the low pressure nozzle hole and the high pressure nozzle; pressure booster spindles (141), (142) and (143) pressurizing the needle valve to boost pressure of low-load fuel; a shuttle valve (150) configured to supply a gauge pressure to the pressure booster spindles, thus raising the pressure of the fuel; a lifting bush valve (180) discharging fuel to a fuel discharge hole through a gap between the fuel discharge hole and a nozzle holder when a solenoid valve (201) is moved upwards; and the solenoid valve (201) controlling pressure applied to the lifting bush valve.
