TURBO-PISTON ENGINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: engine has combustion chamber to which combustible gas under high pressure, air and water are delivered; their combustible and evaporation products flow in succession to above-piston chambers of cylinders through gas-distributing insert rotated by stepping drive; water which is forced out flows from before-turbine chamber to behind-turbine chamber and sets in rotation the turbine of the engine output drive; as a result, exhaust gases from the cylinders which are separated from the combustion chamber are forced out through open valves to exhaust manifolds; water from the chamber opens circular valves and fills the under-piston chambers of these cylinders, thus preparing them for working stroke. For cooling down the exhaust gases and maintaining the reducing pressure, portion of water is injected through injector to the above-piston chamber at the end of its working stroke. The valve-distributing and ignition-evaporation systems may be controlled by computer using the signals from the upper, middle and lower sensors of piston motion. EFFECT: enhanced efficiency. 8 cl, 6 dwg
