INTERNAL COMBUSTION ENGINE “NORMAS” N 38 Russian patent published in 2021 - IPC F02B41/02 F02B73/00 F01B21/02 

FIELD: engine building.

SUBSTANCE: invention relates to the engine building. Two-stroke conrod-free internal combustion engine (ICE), the housing of which is assembled of modules with working stroke. ICE contains intermediate cylindrical gears, semi-axles with bevel gears of the introduced differential consisting of two conical satellites and a chain transmission. The diameters of pistons, cylinders, and prefabricated wings are equal to the diameters of the circles of the protrusions of the teeth of the gears of engagement. The cylinder covers are reinforced with perforated plastics and equipped with two sockets for injectors. The piston has a hemispherical bottom and consists of a cup with the ability to perform limited reciprocating movements in the cylinder by placing four collapsible sockets at the bottom of the cone-shaped piston skirt, where ball joints are fixed, as on a pair of coaxially paired prefabricated wings, and between which four connecting rod-tubes are introduced. A spring-loaded cone-shaped plug valve is mounted in the piston body, which is connected by a rod-tube to the frame. Once a cycle, when hitting the inner surface of the frame of the profiles of two rollers, the exhaust gas bypass opens into the cone-shaped right and left cavities expanding along the perimeter of the cup, while two 3-way gas outlet valves are opened for the flow of gases into the expander cylinder. The profile of the flue is assembled using welding from an odd number of pairs, starting from the number seven, of the calculated length of cylindrical bends made "pipe in pipe" of different diameters, and two diametrical partitions made of steel strips are mounted between these pipes, the input and output edges of which are deployed relative to each other along the axis of the branch by 90°. As part of the air intake organs of the internal combustion engine, in addition to the pipes, check valves and bypass sections, stainless steel bellows with protective covers are also introduced and built into the circuit in parallel.

EFFECT: increasing engine torgue.
