1. A high-efficiency sine rotary engine comprising:
a rotor housing (100) having an inlet pipe (110) and an outlet pipe (120) respectively formed therein, the rotor housing having an inner space (130) formed with a curved inner surface of the rotor housing and configured to allow fluid introduced through the inlet pipe (110) to fill the inner space;
a power shaft (200) rotatably installed inside the rotor housing (100), the power shaft being installed at a position eccentric from a central point of the inner space (130);
a reciprocating rotor (300) formed corresponding to a width of the inner space (130) of the rotor housing (100) and installed through a central portion of the power shaft (200) in a radial direction of the power shaft, wherein the reciprocating rotor is rotated inside the rotor housing (100) while performing linear reciprocating motion in the radial direction of the power shaft (200) according to a rotation angle thereof; and
an eccentric shaft (400) formed to have a smaller diameter than a diameter of the power shaft (200) and installed in the rotor housing (100), wherein the eccentric shaft is connected to a central shaft (301) of the reciprocating rotor (300) and guides the reciprocating rotor (300) such that the reciprocating rotor has a constant rotational orbit, wherein:
the eccentric shaft (400) performs power transmission through gear coupling between the eccentric shaft and the central shaft (301) of the reciprocating rotor (300), and
a part of an outer circumferential surface of the power shaft (200) is in contact with an inner surface of the rotor housing (100), and the rotor housing (100) has an arch-shaped groove (131) formed in the inner surface thereof in contact with the power shaft (200), wherein the groove is formed corresponding to a circumference of the power shaft (200).
