INTERNAL COMBUSTION ENGINE Russian patent published in 2010 - IPC F02B55/02 F01C1/63 

FIELD: engines and pumps.

SUBSTANCE: proposed ICE comprises housing, rotary blade-piston wheels to divide housing space into working chambers, intake valves, nozzles and spark plugs. Rotary blade-piston wheels are arranged in symmetry about the axis and feature even number N of blade pistons. Rotary blade-piston wheels are fitted inside the working chamber on common shaft to allow N blade pistons of one wheel to fit in between blade pistons of the other wheel, to run about said shaft, to alternately be coupled with said shaft and housing and to divide aforesaid working chamber into 2N working chambers multiple of four. The number of nozzles makes N/2, while those of spark plugs, intake valves and discharge holes make N/2. Proposed engine incorporates additionally pickups and retainers of rotary blade-piston wheel position. Aforesaid working chamber is formed between housing inner surface and shaft outer surface.

EFFECT: higher efficiency, power, specific power and improved balance characteristics of ICE.
