To reduce exhaust gas emission by feeding fuel through a passage via slits inside a fuel feeding conduit to an atomizing edge and improving the mixture of liquid fuel and combustion air, before ignition arranging distribution pins between distribution panels comprising the inside of the passage.

Liquid fuel is fed by a fuel nozzle to a fuel conduit 2 of an injection nozzle 1. The fuel is fed through a fuel conduit 2 via slots 6 to a distribution panel 3 forming a passage 7. Distribution pins 4 are arranged along the full length of the injection nozzle 1 in the distribution panel 3, and the fuel is distribution uniformly at the nearer side of atomizing edge 5 in the direction of the flow by the distribution pins. The thickness of the fuel films is decided by a gap width (t) of the passage 7 at the atomizing edge 5. Therefore, the liquid fuel can be fed into the injection nozzle 1 at a comparatively low pressure. As a result of this, the mixture of the liquid fuel and combustion air before ignition can be improved, and exhaust gas emission can be reduced.
