The invention discloses a rotating shaft type rotor engine, which comprises a rotating shaft type rotor mechanism, a compressing
impeller mechanism and an air gate mechanism and has two strokes which are an air inlet compressing
stroke and an air exhaustion acting
stroke, wherein the two strokes are separately completed in two independent cavities of the engine synchronously, so that the rotating shaft type rotor engine has very high
mechanical efficiency; when the engine is in operation,
fresh air enters into the engine through an air inlet of the engine, the compressing
impeller mechanism compresses and does work on the
fresh air to complete air inlet compressing
stroke, and then the air is imported into the cylinder body of the engine through the air gate mechanism and mixed and burnt with
fuel oil to drive the rotating shaft type rotor mechanism to rotate and do work and the
exhaust gas after burning is exhausted through a gas exhaustion channel of an air cylinder body. The rotating shaft type rotor engine disclosed by the invention is small in
relative volume, simple in structure, stable and reliable in operation, energy-saving and
environmentally friendly, convenient to install, wide in application scope and low in manufacturing, use and maintenance costs and has very high economic and practical values.
