ROTARY-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2006 - IPC F02B53/08 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention relates to internal combustion engines with divided cycles. Proposed engine has working chambers with disk rotors of different diameter. Placed between rotors is combustion chamber with working mixture intake ports and burning working mixture discharge ports. Semicylinder is fitted in radial slot of larger diameter rotor, being piston moving relative to chamber housing. Housing of combustion chamber is made in form of cylinder accommodating shaft. Gas distributing disk is rigidly secured on end of shaft in area of rotor of larger diameter. Said disk is provided with port to intake working mixture which can be aligned with port in combustion chamber housing. On opposite end of shaft inner gas distributing cylinder with burning mixture discharge port is rigidly secured, being pointed to end-face surface of smaller diameter rotor and installed with possibility of alignment with discharge port in combustion chamber housing. Spark plug is installed in area of gas-distributing disk.

EFFECT: increased service life of rotary-piston engine owing to increased service life of its combustion chamber and improved thermodynamic cooling of combustion chamber and location of spark plug in point at maximum distance from working rotor.
