RADIAL TWO-STROKE INTERNAL COMBUSTION OPPOSED-PISTON ENGINES WITH WORKING CHAMBERS OF RECTANGULAR SHAPE AND AT LEAST TWO WORKING CHAMBERS IN CYLINDER BLOCK Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention can be used at designing of opposite-piston engines. According to invention, proposed radial two stroke internal combustion engine is provided with opposed pistons placed in at least two rectangular shape working chambers installed between two crankcases. Each crankcase accommodates three crankshafts aligned with synchronizing gears. Middle crankshafts in each crankcase are aligned through gears forming reduction unit to transmit rotation to working shaft. Journals of cranks of crankshafts are placed in pairs in curvilinear slots of rockers on which rods with pistons placed in working chambers are installed. Valve boxes are mounted at end faces of working chambers. Suction valves of said valve boxes are connected with turbocompressor, and delivery valves, with receiver to supply air into working chambers. Receiver accommodates pipes of exhaust manifold connected with exhaust posts of working chambers and are connected at outlet of receiver with turbofan. Throttle valves are installed in center of working chamber. Valve connected by manifold with receiver are furnished with electromagnetic adjusters of opening of valve passage area.

EFFECT: increased efficiency of engine at minimum cost at full-scale production.
