The other sprayed fuel oil that has been sprayed on the inner surface of the combustion cylinder other than the ignition plug setting position cannot be blown away forward by the blowing action of the forced wind, and it is impossible to keep it at that position. Since unburned fuel is generated in some parts, it is not possible to promote the evaporation and combustion of fuel by heating all the spattered fuel within a short period of time to evaporate and vaporize it.

る。Function: First, when starting combustion, forced air for combustion is sent from the air chamber 102 to the combustion tube 10 through the air outlet 103.
1 and at the same time, the fuel is sent to the fuel cup 104 which is being rotated at high speed.The fuel becomes fine particles due to the rotational centrifugal force of the fuel cup 104 and the spraying action of forced air. It is sprayed toward the inner circumferential surface of the corrugated combustion promoting tube 105 arranged at the spray position. By the way, inside the corrugated combustion promoting tube 105, there are alternating vortex retention peaks 106 and ventilation peaks 107.
and are provided in the longitudinal direction of the combustion tube 101, so when starting combustion, the combustion tube 1 passes through the air outlet 103.
A part of the forced wind blown into the 01 collides with the large number of vortex retention valleys 106 and generates a vortex phenomenon of the forced wind in this part, so that all of the spattered fuel oil is The particles are retained in the vortex retention valley 106 while being atomized by the vortex of the forced wind. Therefore, when the spark plug 108 is energized to generate a spark, the fuel accumulated in the swirling state is quickly ignited and burned, and at the same time the fuel accumulated in the other swirling flow retention valleys 106 is ignited and burned. The fire spreads one after another, making it possible to instantly and accurately burn all the sprayed fuel oil.
Since the entire 05 is heated by the combustion flame and reaches a high temperature state, thereafter, the fuel sprayed by the fuel cup 104 quickly evaporates and vaporizes due to the heating action of the corrugated combustion promoting cylinder 105 and the blowing action of forced air. The mixture becomes gas mixture and is vaporized and burned in the combustion tube 101. On the other hand, a part of the forced air injected into the combustion tube 101 is transferred to the inner peripheral surface of the combustion tube 101 and the corrugated combustion promoting tube 1.
The carbon flows from the proximal end to the distal end along the ventilation peak 107 formed between the corrugated combustion promoting cylinder 105 and blows off the carbon that has been deposited on the wall surface of the combustion cylinder 101 in front of the corrugated combustion promoting cylinder 105. I can do it.

If swirling combustion air and swirling cooling air are sent into the ventilation chamber 102 and the cooling ventilation chamber 115, and fuel is further supplied to the inner surface of the fuel cup 104 from the oil supply rotation shaft 109, the fuel will be absorbed by the rotating centrifugal force of the fuel cup 104.

They are placed at intervals all around the circumference, so
The spattered fuel oil is not blown away toward the tip side by the forced wind, but remains in a vortex state, becomes even finer, and is quickly combusted by the ignition of the ignition plug 108. The burning flame is
While circulating on the swirling forced wind, other accumulated fuel is ignited, combusts instantly, and a combustion flame is ejected toward the tip. On the other hand, the forced air blown into the ventilation passage 115 from the ventilation chamber 102 is sent to the combustion tube 1 from the blower port 116...
01 After being injected toward the inner circumferential surface, a vortex retention valley 10 is formed along the longitudinal direction of the combustion tube 101 between the outer circumferential surface of the corrugated combustion promoting tube 105 and the inner circumferential surface of the combustion tube 101.
The combustion flames are blown toward the tip side through the ventilation peaks 107 provided alternately with 6 and 6, and the combustion flames burned in the vortex retention valleys 106 are blown away to the tip side, causing carbon to adhere and accumulate on the inner surface of the combustion tube 101. It replenishes combustion air and promotes complete combustion while preventing combustion from occurring.

ールが付着堆積されることがない。 Therefore, after the corrugated combustion promoting cylinder 105 is heated to a considerable extent due to the continuation of combustion, the sprayed fuel oil is evaporated and vaporized while the vortex is retained due to the heating effect, and the vaporized gas generated is mixed with the forced wind. , exhibits a vaporization combustion state. Moreover, fuel cup 104
Cooling air is constantly blown into the inside of the fuel cup 104 from the ventilation holes 120 on the base end surface thereof, and this cooling air is swirled together with the fuel by the diffusion plate 121 and is ejected toward the tip side along the inner wall surface of the fuel cup 104. Therefore, burnout of the fuel cup 104 is prevented, and carbon and tar are not deposited on the inner surface of the fuel cup 104.

ができる。Effects of the Invention In short, the present invention has the above-mentioned technical means, so that the rotation centrifugal force of the fuel cup 104 and the blowing chamber 102 through the blowing port 103 to the combustion tube 1
The vortex retention valley part 106 provided inside the corrugated combustion promoting cylinder 105 collects all the fuel that has been sprayed in fine particles toward the inner circumferential surface of the combustion cylinder 101 due to the injection action of the forced air blown into the combustion cylinder 101. Although it is possible to quickly and accurately start the ignition by the spark plug 108 by causing the fuel oil to accumulate in a vortex state, it also promotes the spread of fire to other spattered fuel oils that are stagnant in the vortex state. All the fuel can be instantly combusted.

効果を奏する。 Moreover, the combustion flame is blown away toward the tip side by the forced wind blowing out from the ventilation crest 107 formed between the inner circumferential surface of the combustion tube 101 and the outer circumferential surface of the corrugated combustion promoting tube 105. Combustion promoting cylinder 10
It is possible to prevent carbon from adhering and accumulating on the inner surface of the combustion tube 101 on the tip side from 5, and after the corrugated combustion promoting tube 105 is heated by the combustion flame, the spouted fuel is kept in a vortex state. It evaporates and vaporizes while it is retained, and the generated vaporized gas is stirred and mixed with forced air to vaporize and burn it.
