The rotary engine includes a cylinder body having a cylinder chamber, an intake port, an exhaust port, and a spark plug, and a rotor which is received in the cylinder chamber to eccentrically rotate while coming into contact at seal faces thereof with an inner circumferential contact wall of the cylinder chamber to thereby implement intake, compression, expansion, and exhaust strokes. The rotor has an elliptical outer contour, and the inner circumferential contact wall of the cylinder chamber coincides with a specific curve, which is described by opposite apexes of the elliptical rotor in a direction of a major axis, when the rotor eccentrically rotates. The intake port and exhaust port are provided with opening/closing valves, respectively. Sealing performance between the cylinder chamber and the rotor may achieve an enhancement in the efficiency of fuel combustion and engine output and prevent waste of fuel.
