Disclosed is a rotary engine which can improve sealing performance between a cylinder chamber and a rotor, achieve an enhancement in the efficiency of fuel combustion and engine output, prevent waste of fuel and air pollution due to the discharge of uncombusted gas, and achieve a further enhancement in the efficiency of fuel combustion and engine output by supercharging the uncombusted gas into the cylinder chamber in which an intake stroke is implemented. The rotary engine comprises a cylinder body having the 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. The rotary engine further comprises supercharging means to introduce leaked uncombusted gas into the cylinder chamber.
