In the center of the heads 3 of the working cylinders 2 there are round holes 11, through which a cylindrical rod 12 is passed, rigidly fastened to the piston

and the working pistons 14, parts of the cylindrical rod 12 are connected between the sleeves 26, while in the body of the cylindrical rod 12 and the working pistons 14 are provided channels 27 for supplying lubricant.

Hydraulic pushers 21 (Fig. 3) consist of a fixed block 29 mounted parallel to the camshaft 15 with cylindrical bores 29 in which plungers 30 are mounted, one end touching the cams 20 of the camshaft 15, on the other side to the bores 29 in block 28, pipelines 32 are connected via fittings 31, the other end of pipelines 32 is fixed in openings 33 of blocks 34 fixedly mounted on heads 3 of working cylinders 2.

To drive the camshaft 15 and the ignition distribution mechanism 16, the drive (Fig. 4) is equipped with an electric motor 36 powered by an onboard accumulator 37 and an electric generator 38. To synchronize the rotation of the camshaft 15 and move the cylindrical rod 12, an ejector mechanism is used. from the gear train 17 and the tandem 39, one end connected to the cylindrical rod 12. To start the engine, the gear rail 40 is fixed on the cylindrical rod 12, and on the engine housing 10 by means of an axis and a spring chaty sector pedal 41.

The rim 39 (Fig. 5) is connected to the cylindrical rod 12 by means of a pin 42, which passes through the slot in the rival fork 39.

Engine 1 (Fig. 6) can be two-stroke; in this case, suction and exhausting are performed through suction windows 43 and exhaust windows 44 made in the walls of working cylinder 2. The fuel pump 45 is made piston (or diaphragm) and its the piston 48 (or diaphragm) is fastened to the cylindrical rod 12. A hydraulic gas compensator 47 of pressure oscillations is located in the fuel supply line, and an empty cylinder 38 is mounted on the cylindrical rod 12 that controls the fuel supply to the injectors 49 in the heads 3 of the working cylinder 2 ( This is a diesel option). A movable brush 12 is fastened to the cylinder by means of an insulating sleeve 50 movable contacts of an interrupter 51, transmitting voltage from fixed contacts 52 to fixed contacts 53 connected by wires 54 to high-voltage ignition coils 55, which in turn supply high voltage

on the spark plug 24 in the heads 3 of the working cylinder 2.

The drive works as follows.

A cylindrical rod 12 with pistons 13, 14 and 46 reciprocates. With each movement in one of the four halves of the working cylinders 2, a phase of combustion and expansion of the fuel-air mixture occurs, due to which the entire system moves, and in the other three halves the suction, exhaust and compression phases occur. The phase rotation takes place according to the traditional four-stroke or push-pull scheme in accordance with the operation of the cam camshaft 15 and the ignition distribution mechanism 16. The cylindrical rod 12 does not reach the extreme position (contact of the piston 14 about the head 3) because the fuel-air mixture ignites in that half of the working cylinder 2 where the compression phase occurred before and the cylindrical rod 12 begins to move in the opposite direction. The piston pumps 5 alternately suck up the liquid 22 and feed it into the discharge line to drive the motor 9, from which the load is removed, the hydrogas compensator for fluctuating the pressure of the fluid 8 smooths the pressure pulsations reducing the efficiency of the hydraulic motor 9. Moving the end of the cylindrical rod 12 through the rod 19 The crank mechanism 18 and the gear train 17 is converted into rotation of the camshaft 15 and the ignition distribution mechanism 16. The cams of the camshaft move the plungers 30 of the hydraulic pushers 21, which, in accordance with the principles of operation of the volumetric hydraulic transmission, causes the displacement of the plungers 35, which cause the valves 4 in the heads 3 of the working cylinders 2 to open and close.

The crank mechanism 18 transmits only a small fraction of the engine power (only to the camshaft drive 15) and therefore has little effect on the operation of the piston group of the engine, as a result of which it is small-sized. When the camshaft 15 rotates from the electric motor 36, the tang 39, connected to the cylindrical rod 12, makes the rotation of the gear wheel 17 and the camshaft J5 dependent on the movements of the cylindrical rod 12.

The energy consumption of the battery 37 replenishes the electric generator 38 driven by the hydraulic motor 9. The drive is started by pressing the pedal 41, whereby the system rod 12 with the pistons 13, 14 and 46 is displaced to the extreme position and the air-fuel

the mixture in one of the halves of the working pistons 2. The fuel pump 45 operates by displacing the piston 46 (or diaphragm) connected to the cylindrical rod 12; the hydrogas compensator 47 of the pressure oscillations dampens the pressure pulsations in the fuel supply line. In the push-pull pattern, the spool 48 fixed to the cylindrical rod 12 opens the fuel supply to the nozzle at the time of maximum compression. In the two-stroke carburetor version, at the moment of maximum compression, the movable contact of the chopper 51 fixed to the cylindrical rod 12 applies voltage to the ignition coil 55 of the corresponding ignition plug 24.

In the proposed drive, the simplification consists in aligning the reciprocating motion of the working pistons 14

engine 1 with reciprocating pistons 13 piston hydraulic pumps 5. Depending on the operating conditions and purpose of driving the sealing elements 23 in the holes 11 in the heads 3 of the working cylinders 2 may not be. The working pistons 14 have traditional compression rings, but they have working ends on both sides, the pistons do not have extension skirts, since they are centered on the cylindrical rod 12 and the holes 11 in the heads of the 3 working cylinders 2. To lubricate the working cylinders 2 oil can be fed through the channels 27 in the body of the cylindrical rod 12 and the working pistons 14, but mainly lubrication is required here in the holes 11 of the heads 3 of the working cylinders 2, in which the cylindrical rod 12 reciprocates,
