A rotary gear engine includes a gear pump or a Root's blower which can operate at expansion and contraction conditions and is generally comprised of a pair of gears with identical pitch or rotors meshed with each other and mounted on a pair of parallel axles, a vacuum hood and an exhaust hood mounted opposite to the connection between the two gears and closely fitted together with the gears in a cylinder, whereby when in operation, the engine sucks in air at one end and exhaust waste gas at the other to perform intake and exhaust strokes. The combustion chambers and ignition device are provided for obtaining combustion function in compression stroke, and compressed air may be input from the outside or the high pressure gas generated by the combustion chamber may be used for compressing the input low pressure air, and alternatively, a portion of the exhaust gas may be fed back to the combustion chamber to increase the pressure so as to increase the combustion rate to obtain the explosion function thereby providing an engine of high performance.
