FIELD: engine technology.
SUBSTANCE: invention can be used in internal combustion engines. The two-stroke internal combustion engine (ICE) is characterized by the fact that the prefabricated housing (24) is mounted from modules (05) with a working stroke and with the ability to work on fuel of kerosene-gas oil fractions, modules (03) with the ability to work in the air pump mode, modules (04) with early continued expansion of exhaust gases and the module for synchronization of rotation with the power transfer group. The rotation synchronization module with the power transfer group is made with the possibility of synchronous rotation of the introduced three identical gears (12) of gear cylindrical engagement, mounted with a small tension on the shafts (00), (01), (02) and epicycle (11). Each element or link of the internal combustion engine is mounted on the basis of coordinate grid points, which appear like a mosaic when paving a part of the plane with figures of identical convex pentagons, the internal angles of which are always magnitudes: 90°, 105°, 135°, 60° and 150°, and the three sides of the pentagon are strictly equal to half of the fourth one. All six points of the centers of the volume of the combustion chambers and cylinder cavities, when the piston (16) is at the upper dead center (UDC), are located on the circumferences of large circles, the centers of which are also points (00*) and (00**) from the pattern of laying out pentagons. The diameter of the circumference of three small circles with shaft centers (00), (01), (02) is equal to half the length of the fourth side of this convex pentagon, and hence to the diameters of the circles of the projections of gear wheels, the diameters of pistons (16), cylinders (17), taking into account the necessary gaps and tolerances during assembly, the radii of crank centers from shaft rotation centers (00), (01), (02) are equal to each other. The structural dimensions of the elements of the crank mechanism are the same. To reduce the thermal conductivity, the body of the cylinder covers (17) and the surfaces of the piston bottoms (16) are made with reinforcement using plates with perforated holes by joint sintering. The inclination of the plates to the surface, which is in contact with the combustion zone, is equal to an angle of 90°. A number of bellows are integrated into the internal combustion engine, paired with 3-way valves, and with the possibility of synchronous interaction from the shaft drives to form accumulation and regulate the supply of calculated volumes of air to the cylinder of modules (05) with a working stroke, as well as fuel and lubricants to the friction points of this internal combustion engine. The possibility of uniform synchronous rotation of the shafts in this internal combustion engine is also ensured by the fact that the working strokes of the pistons (16) or the same strokes in the cylinders in paired modules (05) are performed not at one time, but after a 180° turn of the corresponding shafts, that is, it is possible to alternate working strokes or the same strokes in the cylinders (17) with the layout options for assembling the modules of this internal combustion engine as part of an unmanned mechatronic device.
EFFECT: increase in the torque and uniformity of rotation on the output power transfer shafts.
