Abstract
The invention discloses a piston rotation type engine. The piston rotation type engine comprises an arc-shaped air cylinder, a plurality of coupling cranks and two planetary gear mechanisms. The air cylinder is arranged in an engine body. An air inlet and an air outlet which are matched with each other are formed in the air cylinder and the engine body. Two piston sets are movably arranged in the air cylinder, and four pistons are evenly arranged on the outer circumference of each piston set. The piston sets are arranged in a spaced mode in the axial direction. The air cylinder is symmetrically divided into eight variable-volume working cavities by the piston sets. Gear rings of the planetary gear mechanisms are fixed to the engine body. According to the piston rotation type engine, the two piston sets rotate in the same arc-shaped air cylinder, and the planetary gear mechanisms are directly made to output power through connecting rods and the coupling cranks; the characteristics of a traditional engine and the characteristics of a rotor engine are brought into full play, so that gas expansion force is directly transmitted to an output shaft for power output; the pistons rotate in the air cylinder to act, and the number of times of acting is increased.
