PURPOSE:To reduce the preheating time by using a heater in a vaporizing part of the title device by a method wherein an heater is equipped to a cylinder body provided with many small holes on its periphery wall, the fuel and the air are supplied into said cylinder body, also a porous burning cylinder is provided with a spacing on a outer periphery of said cylinder body. CONSTITUTION:At a burning initially, a heater 20 laied into a cylinder body 21 is electrified, then said cylinder body 21 is heated, the burning air is supplied into said cylinder body 21 by a blast fun 23 through a air blowing passage 22. Next, a fuel pump 25 is driven, the fuel from a fuel tank 26 is dropped into said cylinder body 21 from a tip nozzle part of a small fuel pipe 24. Then, the fuel is instantaneously vaporized by the wall surface of said cylinder body 21 which is heated at high temperature, the vaporized gas and the air are mixed and the stream is smoothed, inside of a flow stream smoothing space 27, guided to a burning cylinder 28, ignited at a burning space 31 side, sequentially and burned. Then, discharged gas is guided to a releasing end from said burning space 31 by outer cylinder 32. Therefore, a conventional vaporizing chamber can be eliminated, the liquid fuel can be instantaneously vaporized by the heater 20 embedded into said cylinder body 21. |
