WORKING CYCLE OF INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to internal combustion engines of automobiles, tractors and other vehicles. According to proposed method working cycle consists in beginning of compression at moment of overlapping of exhaust port of cylinder wall and overlapping of intake port by valve on cylinder head, with piston moving from bottom dead center to top dead center, combustion of fuel, working stroke, beginning of scavenging and exhaust of waste gases, combination of discharge of exhaust gases and intake of fresh air movement of piston at scavenging to bottom dead center and beginning of piston movement to top dead center. Working cycle is performed during two stoke pf piston: first stroke provides partial scavenging of cylinder and compression, second stroke, provides working stroke and partial scavenging. Combustion of intake and exhaust is provide by 30% of first stroke and 30% of second stroke of piston. EFFECT: increased power output of engine. 2 cl, 2 dwg
