    A two-stroke combustion engine is described which has a symmetrical, floating differential piston (14), having at least two main piston portions (16, 18), each movable in a combustion chamber (28, 30) formed with exhaust ports (46), and each connected to a pre-compression chamber (34, 36) by means of a respective channel (38, 40). The combustion chambers (28, 30) are arranged axially inward of the piston portions and between the chambers lies the pre-compression chamber (32) in which a central double-acting piston portion (22) of the differential piston (14) is arranged on a piston rod (20). The central piston portion (22) divides the pre-compression chamber (32) into two separate supercharging chambers (34, 36), from which the channels (38, 40) leading to the combustion chambers (28, 30) terminate at the end walls of the respective combustion chambers. Valve means (24, 26) on the piston rod (20) serve to open and close the channels so that upon expansion occurring in one combustion chamber material exchange will occur in the other.

    2. The engine according to claim 1, about t l and h and y and with the fact that on the surface of the valves are installed o-rings.
    3. The engine for PP. 1, 2, which is connected with the fact that between the end surfaces of the combustion chambers and the adjacent portions of the hollow cylinders there are recesses communicated with the central cylinder when the pistons are in the external dead point. 4. Motor according to Claims 1-3, characterized in that the suction channel is located in the center of the central cylinder symmetrically with respect to the vertical axis of the engine.
    5. The engine according to claims 1-4, which is based on the fact that the exhaust ports are made in the form of tangential channels exiting the combustion chambers.
    This invention relates to internal combustion engines. The aim of the invention is to increase the reliability and stability of operation of a two-stroke free piston engine by organizing an effective gas exchange within the simplified design scheme. The drawing shows the proposed two-stroke free piston engine. The two-stroke free piston internal combustion engine contains a symmetrically located stepped piston group 1 with a central piston 2, formed with a central cylinder 3 having valve timing organs in the form of suction channels 4, stages 5 and 6 of pre-compression and associated with rods 7 and 8, passage through coaxial channels 9 and 10 in the separation walls 11 and 12, the peripheral pistons 13 and 14, forming with the peripheral cylinders symmetric combustion chambers 15 and 16, placed between the separation walls and The peripheral pistons and the exhaust ports 17 and 18 are connected. The coaxial channels 9 and 10 are made in the form of hollow cylinders placed between the central cylinder 3 and the combustion chambers 15 and 16 concentrically with the rods 7 and 8 that have areas adjacent to the peripheral piston m 13 and 14, stepped valves 19 and 20 blocking the entrance to the empty cylinders when the pistons are in the internal dead center. O-rings 21 and 22 are installed on the surfaces of the valves 19 and 20. Between the end surfaces of the combustion chambers 15 and 16 and the adjacent portions of the channels 9 and 10 there are recesses 23 and 24 communicating with the central cylinder 3 when the pistons are in the dead center. t ke. The suction channel 4 is located in the middle of the central cylinder 3 symmetrically relative to the vertical axis of the engine. Exhaust ports 17 and 18 are made in the form of tangential channels exiting the combustion chambers 15 and 16. . The engine works as follows. Step piston group 1 performs a reciprocating movement in which air is alternately compressed in the corresponding chambers 5 and 6 pre-compressed and pumped through coaxially into the central cylinder 3 due to movement of the central piston 2 through the suction channel 4, which is symmetrically located relative to the vertical axis of the engine. channels 9 and 10, made in the form of hollow cylinders, and recesses 23 and 24 in the combustion chambers 15 and 16, separated from the central cylinder by dividing walls 11 and 12. a healthy charge into the chambers 15 and 16 of the burn, ny comes at the position of 3 11926354
