Claims (1)
に前記圧縮空気通路の途中に燃料供給口を形成し
、ソレノイドに通電することにより電磁的に駆動
せしめられる弁体によつて前記ノズル口を開弁せ
しめ、前記燃料供給口から前記圧縮空気通路内に
供給された燃料を圧縮空気によつて前記ノズル口
から噴出せしめるようにした燃料噴射装置におい
て、前記ノズル口が開弁せしめられた直後に前記
燃料供給口から前記圧縮空気通路内に燃料を供給
せしめ、前記ソレノイドに供給される電圧が低下
するに従つて前記ソレノイドへの通電開始時期を
早めるようにした内燃機関の燃料噴射装置。 A nozzle port is formed at one end of the compressed air passage, and a fuel supply port is formed in the middle of the compressed air passage, and the nozzle port is opened by a valve body that is electromagnetically driven by energizing a solenoid. In the fuel injection device, the fuel supplied from the fuel supply port into the compressed air passage is injected from the nozzle port using compressed air, wherein the fuel supply is performed immediately after the nozzle port is opened. A fuel injection device for an internal combustion engine, wherein fuel is supplied into the compressed air passage through a port, and as the voltage supplied to the solenoid decreases, the time to start energizing the solenoid is advanced.
