INTERNAL COMBUSTION ENGINE "NORMAS" N20 Russian patent published in 2020 - 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, modules with synchronization of rotation of line number of shafts per one power take-off shaft and modules with early extended expansion of exhaust gases, axial lines of the latter are located with camber angle 34°. Prefabricated structure is mounted with allowance for coordinate grid, on which is predetermined location of centers of circles of one diameter, located near one circle of larger diameter with single reference point on hollow shaft axis so that it is possible only between rows of these circles to conduct intersection of tangential lines, wherein axes of modules with working stroke and early extended extension, which are parallel to said tangential lines, intersect at angles 73°and 107°, and points located on axial centers of volumes of combustion chambers of cylinders together with point located on axial centers of shafts of modules with early extended expansion, form on coordinate grid figure of rectangular triangle with vertices in these points. At that, diameters of circles are equal to diameters of pistons, cylinders, diameters of side jaws arranged in intermodule partitions between pairs of which there are cranks arranged, and are also equal to diameters of circle of meshing gear teeth hollows, made with possibility to synchronously transmit torque moment to cylindrical idler gear, rotating hollow shaft with lower speed. Pistons are connected through piston pin with even or odd number of straight plates of same length, having the shape of double-tee profile with short but thickened shoulders, with perforated holes surface, central through hole and with lugs. Plates are connected via ball joints with appropriate semi-cylindrical prefabricated linkages, which, through the presence of guide trays arranged therein, where the introduced crank in the presence of forces is configured to perform limited back-and-forth movement; and air intake elements system includes bellows and built-in 3-way valves, which are located at the shaft through shaft center, bypass chambers of 3-way valves are formed by connection of internal cavity of air ducts with made holes in locking or adjusting element of valve, having spherical shape and possibility of synchronous rotation from coaxial connection with these shafts, as well as check valves, which are made with limited rotation of their gate. Piston is assembled, wherein piston bottom includes recess of two shaped holes for formation of flows, inner cavity of shell is reinforced with shaped perforated plates, arranged side cuts at angles, which are not acute to surface of barrel, cylinder covers contain reinforced figured perforated plates arranged with orientation of arrangement of side cuts of plates.

EFFECT: technical result consists in increasing engine torque.
