FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: internal combustion engine of first design version has cylinder 1 with head 3 and piston 2 forming combustion chamber. Underpiston space 5 communicates with atmosphere. Cylinder head 3 accommodates intake valve 6 communicating combustion chamber 4 with atmosphere when piston 2 moves to bottom dead center and non-return valves 7 providing exhaust of products from combustion chamber into atmosphere. Combustion chamber 4 has antechambers 8, each accommodating oxyhydrogen gas valve 9 and spark plug 10. Antechambers should be preferably made in side wall of cylinder above piston in bottom dead center. Method of operation comes to communicating combustion chamber with atmosphere when piston moves to bottom dead center, sealing combustion chamber, delivering and igniting fuel mixture provided at the moment when piston approaches bottom dead center. Oxyhydrogen gas is used as fuel mixture. Internal combustion engine of second design version has combustion chamber 4 formed by cylinder 1 with head 3 and piston 2 whose underpiston space 5 communicates with atmosphere. Head 3 accommodates fuel mixture supply valve 9 and spark plug 10. Non-return valves 7 providing exhaust of products from combustion chamber 4 into atmosphere are installed in side wall of cylinder 1 above piston bottom dead center. method of operation of this engine comes to delivery of fuel mixture into combustion chamber and ignition of mixture at the moment when piston approaches top dead center. Exhaust of products from combustion chamber through non-return valves is provided at the moment when piston approaches bottom dead center. Engines are two-stroke machines. In engines of first design version piston stroke to top dead center is its working stroke, and in engine of second design version both strokes are working ones. EFFECT: creation of ecologically safe internal combustion engine operating on oxyhydrogen gas. 6 cl, 2 dwg |
