METHOD OF FUEL COMBUSTION IN EXTERNAL COMBUSTION ENGINE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; external combustion engines, steam boilers and heating systems. SUBSTANCE: metered amount of fuel and oxidizer is delivered into hermetically closed combustion chamber. Fuel-air mixture is ignited by means of spark plug. After combustion of mixture and completion of heat exchanger, combustion products are brought out of combustion chamber. If necessary, process is repeated many times. Combustion products can execute delivery of fuel and oxidizer into combustion chamber. Brought out combustion products can be used for setting into motion piston of steam machine. Moreover, delivery of water or monatomic gas into combustion chamber at the moment of maximum burning temperature of fuel-air mixture can be provided. EFFECT: increased economy owing to reduction of heat losses and overall dimensions of combustion chamber and exhaust pipe. 2 cl, 1 dwg
