Description

  The present invention relates to the structure and rotation method of an engine that generates mechanical power by burning fuel, and in particular, uses waste heat generated by combustion of liquid or gaseous fuel to generate water vapor and generate steam to generate rotational force. It is related to the engine to make.

  Conventionally, an engine using a method that creates a reciprocating movement of a piston by a combustion explosion of fuel and further converts this reciprocating movement into a rotating movement to create a mechanical rotating movement has been mainstream. This engine is currently inefficient because it produces rotational motion from reciprocating motion. At present, waste heat generated in the combustion process is exhausted as it is. In order to save energy, some devices have been proposed to recover the waste heat, evaporate the water to produce water vapor, use the explosion of the water vapor, and rotate the engine. If used for steam explosion, conversely, the engine output decreases. Adding a special rotating rotor and using it for steam explosions requires the engine to be large, which can hinder the location and capital investment. Therefore, the current situation is that the steam explosion engine has not yet been put into practical use.

  Therefore, it is desired to develop a high-efficiency engine having a new structure that can increase the engine output by steam explosion using the waste heat of fuel combustion.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a highly efficient steam explosion engine.

  The communication described in the present invention means that a structurally designed communication path is provided, and a gap necessary for rotation between the rotor and the rotor case is not a communication path. In addition, the position and angle of the fuel inlet shown in each figure are not strictly mechanical drawings but are shown in principle. Further, the rotor described in the present invention is not limited in the outer shape of the circumference. For example, the vertical distance from the outer point of the circumference to the center of the rotation axis may or may not be equal. Although the engine described in the present invention is expressed as an engine unit, it can function even if it is used as it is. However, it is possible to increase the output by rotating a plurality of these engine units connected to one rotating shaft. it can. The engine rotor may be made heavier or lighter and adjusted according to the application. The fuel described in the present invention may be liquid or gas.
