A topological rotary engine includes a first transmission mechanism, a second transmission mechanism, a valve mechanism, a rotor, and a cylinder. The rotor is arranged in an inner chamber of the cylinder. A cross section of the rotor is a curved-side topological polygon having n sides.

The present invention relates to a multi-cylinder rotary engine having triangular cylinders. The present invention only applies to a multiple-type rotary engine having triangular cylinders and an elliptical rotor piston, from among rotary engines having various structures. Therefore, by applying a serial type of the present invention, whereas a parallel type has to be used in a multi-cylinder type engine according to the prior art, effects of addressing a rotation error during operation and improving durability are achieved because an integrated-type crank shaft, rather than a separated assembly type which is complicated and weak at a crank shaft portion, can be used. Also, in the serial-type structure, as the number of components such as parallel shafts, gears, etc. is greatly reduced, the size of the engine is also reduced to improve economic efficiency, and moreover, noise and a failure rate are lowered, which ultimately contributes to the extension of the lifespan of the engine and miniaturization of the engine. In addition, although ignition and explosion locations of the cylinders are different from each other, deformation at one side (ignition, explosion, and opposite position), which is one of the problems of rotary engines, is reduced, and thus, an effect of contributing to the extension of the lifespan of the engine is provided.
