ないようになっている。FIG. 1 is a 191-plane view showing an embodiment of the mechanical burner for an automobile according to the present invention. A hollow rotating shaft 4 is rotatably supported by a bearing 2.3 mounted on the casing of the mechanical burner 1. An armature 5 is fixed to the hollow rotating shaft 4, and a direct current is applied to the armature 5. In addition, a blower fan 7 is fixed to one end side of the rotary shaft 3, and the tip of the rotary shaft 4 on the side to which the blower fan 7 is fixed. A fuel nozzle 8 is attached to this part, and this part is inserted and fixed into a fuel cup 9. Furthermore, an air nozzle 10 having a ring-shaped opening is formed on the outer periphery of the fuel cup 9. A fuel nipple 11 is provided at the other end of the hollow rotating shaft 4, and this fuel nipple 1
The casing fixing the fuel nipple 11 on the outer periphery of 1 has an air introduction hole 12.
A magnet 13, which forms a stator inside the casing, is arranged on the outer periphery of the t-armature with a predetermined gap therebetween. Further, an air introduction hole 14 is also formed in the casing portion that supports the bearing 3. Further, a brush 15 is in sliding contact with the commutator 6. In addition,
The bearing 2 is provided with an oil seal to prevent the fuel flowing in from the fuel nipple 11 from leaking to the rear side.

って吹き飛ばされ名。Next, the operation of this embodiment will be explained. When direct current is applied to the brush 15, the armature 5 begins to rotate due to the electromagnetic force applied to the magnet 13, and at the same time, the blower fan 7 and fuel cup 9 also begin to rotate.If fuel is injected from the fuel nipple 11 in this state, Fuel is provided by hollow rotating shaft 4
The fuel passes through the center and spreads thinly on the inner wall of the fuel cup 9, and furthermore, the edges of the fuel are blown away in fine particles around them by the centrifugal force of the rotation.

る。On the other hand, air is blown by the blower fan 7 and the air is blown out from the air nozzle 10. FIG. 2 shows the flow of the above-mentioned living air and fuel, where the flow of air is indicated by a broken line arrow A, and the flow of fuel is indicated by a solid line arrow F. The fuel blown out from the fuel cup 9 collides with the air blown out from the air nozzle 10 and forms fine sparks, and if the fuel is ignited in this state, an ideal fire can be formed.

室１８内に噴射される。FIG. 3 is a schematic diagram showing the rows in which the Honjitsu 7AiV10 mechanical burner for automobiles is used. The fuel in the fuel tank 16 is pumped by a fuel pump 17 to the fuel nipple portion of the mechanical burner l. As described above, the fuel is made into a fine mist by the mechanical burner 1 and injected into the combustion chamber 18.

の放出が防止される。An ignition plug [9 is inserted into the combustion chamber 18, and the ignition plug ignites the fuel. The exhaust gas flowing inside the exhaust pipe 20 is heated by the fire of the fuel injected by the mechanical burner 1, and the particulates in the exhaust gas are re-burned and extinguished by the thermal energy, and the attached components are released into the atmosphere. Release is prevented.

間を節約することができる。According to this embodiment, the fuel coming from the hollow rotating shaft 4 and the air nozzle 10 from which the air is blown by the blower fan 7 are located at approximately the same location, so there is an effect of making the mechanical burner smaller. By using a small mechanical burner, only the fuel pump needs to be laid out, which simplifies the configuration of the exhaust reburning device and saves space for installing the device.

を節約し得る効果がある。FIG. 4 is a sectional view showing another embodiment of the present invention. The structure of this embodiment is almost the same as that of the previous embodiment, but the difference is that an oil supply fan 21 is attached to one end of the air rotation shaft 4, and a fuel cylinder is configured in this part, and the fuel is supplied by this pump. In the seventh embodiment, in which the air is fed under pressure into the hollow rotating shaft 4 through the hole 22, the blower and fuel pump are integrated, so there is no need to install an external fuel pump, and the exhaust This has the effect of further simplifying the structure of the reburning device and saving installation space.
