INTERNAL COMBUSTION ENGINE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; rotary internal combustion engines. SUBSTANCE: proposed internal combustion engine has two identical coaxially installed rotors with cylinders and piston in form of torus sections. Each rotor has two axially symmetrical toroidal cylinders and pistons forming four working chambers with combustion chambers in form of cylinder with spherical dome and flat bottom made in half in head of corresponding cylinder and in half in piston crown, flat bottom of combustion chamber being gas exchange port. This port has L-shaped ring seal pressed to gas distributing ring mirror by spring U-shaped ring in form of bellows corrugation. Two gas distributing ports of first rotor are overlapped by gas distributing ring mirror of engine housing, and two ports of other rotor, by mirror of front cover of engine housing. gas distributing mirrors have intake and outlet ports intercoupled with intake and outlet channels-manifolds and holes for spark plug or nozzle. EFFECT: increased power output, reduced vibration. 11 dwg
