A rotary engine, comprising: the rotor is provided with a rotor and a cylinder, the rotor rotates in the cylinder, and the device is characterized in that: there are crank one and crank two on the bent axle, crank one and crank two are integrative, the bent axle center, crank one axle center and crank two axle centers are on same straight line, the bent axle drives a crank slider through the crank and makes a round trip to slide in crank one slider track, crank two drive crank two sliders make a round trip to slide in crank two slider tracks, it slides on the cylinder shape line curved surface to drag rotor shape line curved surface, the rotor shape line contacts with three radial gasket on three equilateral triangle summit all the time at the removal in-process rotor shape line, the terminal surface gasket between every two seal pins all the time with rotor terminal surface contact, three airtight space is sealed into to three cylinder, along with the removal of rotor in each cylinder, three stroke has been formed in every cylinder: the gas exchange, compression and combustion work application are carried out, each stroke respectively occupies 120 degrees of the rotation angle of the crankshaft, each cylinder completes three strokes and one working cycle when the crankshaft rotates for one circle by 360 degrees, and six work application cycles are completed by the three cylinders when the crankshaft rotates for two circles; the shaft axis of the crankshaft, the shaft axis of the first crank and the shaft axis of the second crank are parallel to each other and are arranged at intervals up and down, and the shaft axis of the second crank is arranged between the shaft axis of the crankshaft and the shaft axis of the first crank.

2. The engine of claim 1, characterized in that: a crank I rotates in an inner hole of the crank I sliding block, and two outer edges of the crank I sliding block slide back and forth on a crank I sliding block track, namely slide back and forth along the short axis of the rotor; a second crank is arranged in an inner hole of the second crank sliding block to rotate, and meanwhile, two outer edges of the second crank sliding block slide back and forth on the second crank sliding block track, namely slide back and forth along the long axis of the rotor.

3. The engine of claim 2, wherein: the top point of the equilateral triangle is a balance contact point of the curved surface of the rotor-shaped line and three radial sealing pieces on the engine shell; when the engine works, the short axis of the rotor always passes through a central point of the first crank, the long axis of the rotor always passes through a central point of the second crank, the short axis of the rotor is vertical to the long axis of the rotor, and the first crank rotates by an angle a relative to the engine shell; the short axis of the rotor rotates by an angle b relative to the engine shell; a. b is in a rotating relation: a: b is-2: 1, and the negative sign represents the opposite rotation direction of the positive sign; the equilateral triangle vertices remain in relative position to the rotor minor axis and move in a-2: 1 relationship with the rotor minor axis, the trajectory of the equilateral triangle vertices is the rotor profile.
