(2) the twin-tub structure of synchronous exclusive-OR function, make the symplex structure of suction pressure and quick-fried row's working procedure by two cylinders, finish respectively, like this, make its variation of force each point on circumference, per moment is all symmetrical fully, solved the problem that single cylinder construction rotor motor is concentrated the side pressure and the stress of main shaft fully, its stress is disperseed, increase torsion, the load hardware features is good, the raising revolution.

(3) outburst chamber sectional area is little, and the arc stroke is long and relief opening is often opened, and the waste gas delivery ratio is more thorough, does not produce carbon deposit, and not fusion waste gas during burning makes full combustion of gas, and blowdown flow rate is reduced, and has saved fuel.

(4) because of the present invention simple in structure, the geometrical shape of component is simple, and has reduced the in-fighting of energy.Because be easy to processing, so can adopt wear-resisting, heat-resistant material such as industrial ceramics.Make motor become heat accumulating type, reduce thermal energy consumption, increased the thermal efficiency by heat radiating type.

(5) because cylinder body and cylinder body are parallel-connection structure, cam is parallel-connection structure with cam under main spindle multiple spline cooperates, thus the adjustable angle between its sideboard, the adjustable angle between its cam, increased the adjustable extent of compression ratio, so originally start functional adaptation to use pluralities of fuel.

(6) cylinder body of this motor and cam can be that twin-tub also can adopt the multi-cylinder structure, cam follower can be two symmetrical lift drift angles, also can adopt a plurality of symmetrical lift drift angles, it can be to equal the four-ignition work done that cam follower is whenever circled, it also can be the work done of repeatedly lighting a fire, make its adaptability strong like this, can replace being applicable to the available engine of various occasion work.

Following accompanying drawing has been described one embodiment of the present of invention.

Fig. 1 is the structural representation of a kind of double-cylinder cam-type rotor engine of the present invention.
