Original design on the power transmission mechanism of a twin-rotor piston engine

In order to increase the power density of the piston engine, the power transmission mechanism of a twin-rotor piston engine based on differential velocity principle is introduced. Firstly, the precept of the engine principle is developed, and the velocity of the rotors is designed, then the structure and the kinematic simulation of the power transmission mechanism are derived. The results show that the combined mechanism composed of the hypocycloidal planet gear mechanism and the crank rock mechanism can satisfy the design principle of the twin-rotor piston engine, the number of the airtight cavity and its vary is related to the gear ratio, the power frequency of the engine is increased obviously.
