INTERNAL COMBUSTION ENGINE Russian patent published in 2020 - IPC F02B19/04 F02B59/00 F02B75/24 F02F3/24 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine building, particularly, to creation of internal combustion engines. Used in autonomous cars and vehicles, mainly in light motor aircraft, automobiles, tractors and agricultural machines. Engine comprises hollow rod connecting pistons, made equal to diameter of pistons and equipped with zigzag-shaped closed grooves of semicircular cross-section, which interact with hemispherical ends of rollers mounted on needle and thrust roller bearings in hubs of cylindrical gears, which encircle the stock, coupled with the power take-off shaft through coupling and matching cylindrical gears, which significantly reduces the cost of the drive and increases its mechanical efficiency by more than 95 %. Application of mechanical connection of hubs of the main cylindrical gears with tail part of sleeves of cylinders – exhaust valves and pneumatic inertial system of air inlet into working cylinder reduces consumption of heat energy for gas distribution. Injection of liquid fuel into antechamber with arrangement of vortex turbulent flow in combustion chamber substantially increases homogeneity of mixture, ignition of charge with direct jump of flame reduces probability of detonation.

EFFECT: reduced wear of movable parts and considerable increase of overall efficiency.
