PURPOSE:To improve an atomizing efficiency and properties of particle size reduction and to efficiently and perfectly burn liquid fuel, by forming an air current flowing in an outward direction from the interior of a colliding body with which a jet stream of liquid fuel collides. CONSTITUTION:Fuel, fed from a fuel tank, is pressurized by a fuel pump 1 and is jetted through pores in a nozzle 13. A colliding body 8 has an annular air port 9 and the air fed by a blast fan 10 is fed to the colliding body 8 through an air feed pipe 11. This constitution creats an air current flowing in an outward direction from the center of the colliding body 8, and as a result, a liquid film, formed by a colliding surface 12 and having a speed in a radial direction, is further spread in a radial direction with the aid of the air current, the liquid film is reduced in thickness, and the produced spray is decreased in its particle size. |
