PURPOSE:To enhance the durability against heavy components of fuel by forming a heated surface in a vaporizing chamber which is heated by a heating source, and disposing multiple fuel supply nozzles that inject the fuel to cause it to contact said heated surface. CONSTITUTION:A side rim of a vaporizer 11 is integrally connected to one side of a base plate 41 in normal angle. An outer plate 42 which is sweliing outwardly with a remaining flanged section is integrally connected to the other side of the base plate 41 at the flange. Between the base plate 41 and outer plate 42, a flat second vaporinzing chamber 43 is formed. The inner surface of the outer plate 42 of the second vaporizing chamber 32 is made a heated surface 44, and the second vaporizing chamber 43 is connected to an opening 24a in one side of the first vaporizing chamber 24. First and second fuel supply nozzles 45, 46 communicating with the second vaporizing chamber 43 are connected to th upper and lower parts of the base plate 41. The fuel supply nozzles 45, 46 have an injection port 45a, 46a at the end. By this arrangement, the fuel is injected out of the fuel supply nozzles to contact the heated surface of the vaporizing chamber for quick vaporization of fuel, and by switching the fule supply nozzles 45, 46, the durability against heavy components can be enhanced. |
