Claims (1)
圧縮空気通路の途中に設けられた燃料供給口から
前記圧縮空気通路内に供給された燃料を、前記圧
縮空気通路内に供給された圧縮空気によつて、前
記ノズル口から噴射せしめるようにした燃料噴射
装置において、前記燃料供給口と前記ノズル口と
の間の前記圧縮空気通路内に多孔質部材を配設し
た内燃機関の燃料噴射装置。 A nozzle port is formed at the tip of the compressed air passage, and fuel supplied into the compressed air passage from a fuel supply port provided in the middle of the compressed air passage is converted into compressed air supplied into the compressed air passage. Therefore, in the fuel injection device for an internal combustion engine, in which fuel is injected from the nozzle port, a porous member is disposed in the compressed air passage between the fuel supply port and the nozzle port.
