ENGINE WITH HEAT REGENERATION (VERSIONS) AND METHOD FOR ENERGY GENERATION IN ENGINE Russian patent published in 2009 - IPC F02G5/02 F01K23/06 

FIELD: engines and pumps.

SUBSTANCE: invention is related to steam engines. Suggested engine with heat regeneration uses water both as working fluid and as lubricating material. During operation water is supplied by pump from collecting tray via coil around exhaust opening of cylinder, and as a result water is previously heated by steam exhausted from cylinder. Then preliminarily heated water is supplied to steam generator and is heated by means of combustion chamber to generate superheated high-pressure steam. Air is preliminarily heated in heat exchanger, and then is mixed with fuel from fuel sprayer. Spark plug ignites sprayed fuel, and flame and heat centrifuge is created inside combustion chamber. Speed and torque moment of engine are controlled by system of yoke and cam, which opens needle valve for inlet of superheated high-pressure steam in cylinder, inside of which there is piston of reciprocal travel. Supplied steam expands in explosive action at piston top at high pressure, which makes the piston go down, at that piston with the help of driving force transfer turns joined crank cam and crankshaft. Spent steam is sent via centrifugal condenser, having system of flat plates. Cooling air from air blowers circulates via flat plates to transfer steam into liquid condition. Condensed water is returned into collecting tray for further use with the purpose of steam generation. Method is considered for energy generation in engine.

EFFECT: provides for increased efficiency factor and engine performance, by provision of heat regeneration and engine operation at critical pressure and temperature.
