Internal combustion engine with pistons which rotate and move axially

摘要: This invention describes the configuration, construction, working principle and possible applications for PROHPI internal combustion engines. new type of engines works by means one or more both rotating reciprocating cylindrical pistons within cylinders with following characteristics: —� Piston top cylinder head have matching wavy (e.g. sine wave alike) surfaces; By rotation reciprocation, forms form alternating compressing expanding chambers; During maximum compression, compressed air - fuel mixture is pressed through channel like connections between chambers expansion Fuel can be injected / ignited just before such channels; configured two stroke four operation; Otto, Diesel direct injection spark ignition The engine applied stationary non-stationary power units, e.g. to drive generators, compressors pumps, pile driving sheet drivers aviation, automotive, train, nautical other mobile primary lines and/or range extenders.
