INTERNAL COMBUSTION ROTOR ENGINE WITH ASYMMETRIC COMPRESSION AND EXPANSION Russian patent published in 2019 - IPC F02B53/08 F01C1/22 F01C11/00 

FIELD: machine building.

SUBSTANCE: invention relates to the field of rotary internal combustion engines. Essence of the invention consists in the fact that the working fluid (air or fuel-air mixture) absorption and compression takes place in the compressor section, air-fuel mixture ignition and combustion is in located in the middle engine cover combustion chamber, the working gas expansion and subsequent pushing out is in the turbine section. In the radial direction, the compression and expansion chambers are limited by the compressor and turbine sections stators cylindrical surface, each with its own stator. Compression and expansion chambers volumes changing is provided by rotating around two centres (the eccentric shaft centre of rotation and the rotor on the eccentric shaft centre of rotation) rotors with the main and rotor bearings necks eccentricity. In the axial direction, the compression and expansion chambers are limited by the stator covers (front, middle, rear), in which the eccentric shaft main supports and the rotors rotation synchronizers bearings are located. Working fluid compression degree and the working gas expansion degree are determined by their own section (compressor, turbine) geometrical parameters. Expansion ratio to the compression ratio relationship in range of 2÷10 is achieved by the stators width, the stators working surfaces diameter and the eccentric shaft axis of rotation eccentricity and the rotor axis of rotation changing, either one of these dimensions, or combination thereof.

EFFECT: technical result consists in increase in the engine efficiency.
