INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: power engineering; transport. SUBSTANCE: engine has cylinder-piston group, cylinder head with combustion chamber, timing mechanism, fuel-air mixing, fuel, lubrication and cooling systems, connecting rod, crank with two support rollers rotating in circular path. Diameter of circle of rotation of crankpin axis is smaller than diameter of circle of rotation of axes of rotation of support rollers of crank in circular path. Torque from crank is removed by coupling or planetary drive and is transmitted to engine longitudinal shaft. Torque multiplication mechanism is mounted on end of engine longitudinal shaft. Said mechanism is provided with driving and driven cranks. EFFECT: increased output power and torque and contact strength. 12 dwg
