摘要： The present invention provides a rotary engine comprising: a housing provided with three lobe accommodation parts; a rotor which is provided with two lobes continuously accommodated in the lobe accommodation parts, has an intake storage part communicating with an intake port provided on the front surface-side, and has an exhaust storage part communicating with an exhaust port provided on the rear surface-side; an intake-side housing cover provided with an intake hole communicating with the intake storage part; an exhaust-side housing cover provided with an exhaust hole communicating with the exhaust storage part; and a crankshaft, wherein the flow of an exhaust gas into a stroke chamber during an intake stroke is reduced by preventing the exhaust storage part, at a portion of a section in which the exhaust port is open, from communicating with the exhaust hole during the intake stroke.
