INTERNAL COMBUSTION ROTARY ENGINE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; internal combustion engines with nonuniform movement of pistons. SUBSTANCE: proposed engine has round housing accommodating four blades-pistons secured by pairs, with 180 deg displacement, on carrying disks installed for rotation. Blades-pistons form four working chambers between pistons of one carrying disks and pistons of other carrying disk. Each carrying disk is installed on its shaft. Shafts are arranged coaxially relative to each other and are coupled with control mechanism provided with closed four-member mechanism. Each member of this mechanism is made in form of articulated triangle two vertices of which are in contact with complex trajectory contour described by eight arcs of three different diameters, and one of vertices is coupled with blade-piston. EFFECT: improved reliability and reduced fuel consumption by provision of isochoric combustion in engine chamber. 2 dwg
