  FIG. 2 is a schematic diagram inside the internal combustion engine 100 in the embodiment of the present invention. FIG. 2A is a perspective view of the internal combustion engine 100 in the embodiment of the present invention. 2 (b) and 2 (c) are cross-sectional views of the combustion section 20, the communication passage 30, and the valve 40 in the embodiment of the present invention, and are views showing an explosion in the combustion section 20. FIG. . The combustion part 20, the communication path 30, and the valve 40 will be described below using the above drawings.

  As described above, the combustion unit 20 mixes fuel and gas inside to ignite and explode. For example, the combustion unit 20, the fuel supply unit 22, the gas supply unit 23, and the ignition unit 24 (see FIGS. 2B and 2C). The fuel supply unit 22 supplies fuel into the combustion chamber 21. The fuel supplied from the fuel supply unit 22 to the combustion chamber 21 includes all fuels such as liquid fuel and gaseous fuel such as hydrogen gas. Further, it is assumed that the fuel supply unit 22 vaporizes or supplies the fuel into the combustion chamber 21 according to the type of fuel used, but supplies the fuel into the combustion chamber 21 in any manner. This is not limited to this, and the present invention includes other modes. The gas supply unit 23 supplies gas into the combustion chamber 21. Further, the gas supply unit 23 supplies a gas amount corresponding to the type and amount of fuel supplied by the fuel supply unit 22 into the combustion chamber 21. As a result, an air-fuel mixture in an optimum state for combustion can be supplied into the combustion chamber 21 no matter what fuel is used in the internal combustion engine of the present invention. The ignition unit 24 ignites at a predetermined timing after the fuel and gas are supplied to the combustion chamber 21. This ignition causes an explosion in the combustion chamber 21. The combustion chamber 21 is made of a material and a structure having high temperature durability and impact durability so that an abnormality such as damage to itself does not occur due to explosion in the combustion chamber 21. According to the combustion section configured as described above, an internal combustion engine that can handle any kind of fuel can be realized. In addition, in FIG. 2A, although the two combustion parts 20 are provided, this is an example and there may be one or three or more.

  As described with reference to FIG. 1, the communication path 30 is a path that allows the combustion unit 20 and the impeller unit 10 to communicate with each other. Since the communication path 30 guides the blast supplied from the combustion unit 20 to the blade member 13, a mode in which the supplied blast is transmitted to the blade member 13 without loss is preferable.

  2B and 2C, the valve 40 is provided inside the connecting portion between the combustion unit 20 and the communication passage 30, and is opened when an explosion occurs in the combustion unit 20. When the valve 40 is closed, the combustion chamber 21 and the communication passage 30 are separated from each other. The valve 40 may be opened at the time of explosion in the combustion unit 20, and may be either a mechanical valve or an electronically controlled valve if this can be realized. Further, the valve 40 is configured to have high temperature durability and impact durability so that an abnormality such as damage does not occur due to an explosion in the combustion chamber 21. The valve 40 prevents the fuel supplied from the fuel supply unit 22 from leaking into the impeller unit 10 through the communication path 30. Thereby, all the fuel supplied from the fuel supply part 22 can be used for the explosion in the combustion chamber 21, and a desired blast can be given to the blade member 13. As a result, fuel can be used efficiently and wasteful fuel consumption can be reduced.

  Next, the operation of the internal combustion engine 100 in the embodiment of the present invention will be described. As shown in FIG. 2B, when the fuel is supplied from the fuel supply unit 22 into the combustion chamber 21 and the gas is supplied from the gas supply unit 23 into the combustion chamber 21, the ignition unit 24 is activated at a predetermined timing. Ignite. Then, an explosion occurs in the combustion chamber 21 as shown in FIG. When an explosion occurs in the combustion chamber 21, the valve 40 opens. When the valve 40 is opened, the blast C is directed to the impeller portion 10 through the communication passage 30.

  The blade member 13 of the impeller unit 10 located in the vicinity of the exit of the communication passage 30 receives this blast C and rotates in the direction of arrow D. And the gas which entered from the communicating path 30 is exhausted from the surface 16 side which is not obstruct | occluded (it provided with the exhaust part) as shown by arrow E. The above is continuously performed at a predetermined timing in the two combustion sections 20, and the rotational force in the direction of arrow D is transmitted to the outside as power of the internal combustion engine 100 through the rotary shaft 11.

  In order to transmit the blast C supplied from the combustion unit 20 to the blade member 13 without loss, it is preferable that the communication path 30 is inclined with respect to the blade member 13 as shown in FIG. . That is, when the angle formed by the axis 31 of the communication passage 30 and the receiving surface 13a, which is the surface that receives the blast of the blade member 13, is F, the direction of the supplied blast is all the movement of the blade member 13 in the rotational direction. The angle F may be determined so as to be converted. If it does in this way, the receiving surface 13a of the blade member 13 can receive the blast C supplied from the communicating path 30 without loss. As a result, the internal combustion engine 100 can continuously transmit desired power to the outside even with a small amount of fuel, and the internal combustion engine 100 with low fuel consumption can be realized.

  Further, it is preferable that the combustion section 20 is also inclined with respect to the blade member 13 from the same concept as the communication path 30. That is, for example, it is preferable that the axis line in the combustion section 20 coincides with the axis line 31 of the communication passage 30 and the axis line in the combustion section 20 and the receiving surface 13a of the blade member 13 are inclined so as to have the angle F.

  FIG. 3 is a plan view of an impeller unit 210 according to another embodiment of the present invention. The blade member 13 in the impeller portion 10 has a configuration that spirally extends from the rotary shaft member 12 toward the outside. However, the blade member 213 in the impeller portion 210 is not spiral, but the rotary shaft member 212. It extends radially outward from the outside.

  In addition, the aspect of the blade member in the impeller part demonstrated in FIG. 1 thru | or FIG. 3 above is an example, and if the blast C supplied from the combustion part 20 can be received and rotated by the blade member 13, it will be other than that The present invention also includes all the embodiments.

  As described above with reference to FIGS. 1 to 3, according to the internal combustion engine 100 in another embodiment of the present invention, the impeller unit 10 is rotated by the blast generated by the explosion in the combustion unit 20 to generate power. An excellent effect of being able to transmit can be achieved.

  Further, the embodiment of the present invention described above shows an example for embodying the present invention, and the present invention is not limited to this, and various modifications are made without departing from the gist of the present invention. be able to. That is, the shape and size of the impeller unit 10, the combustion unit 20, the communication path 30, the valve 40, and the casings that have been described above are merely examples, and those other than those illustrated in FIGS. It is included in this invention in the range which does not deviate from the summary of this invention.
