The invention relates to the field of engine construction and can be used in the transport and energy sectors.

Known multi-cylinder engine having a pump and power cylinders, interconnected gear camera with pistons, performing synchronous movement (WO 85/02655, F 02 In 33/22, 1985).

Also known engine having a piston rigidly connected with a rod on the end of which is a crossbar with two fingers and put them rods, rotating towards each other, and the two synchronizing gears (TSB. so 24. I. str. Moscow. Publishing house "Soviet encyclopedia". 1976. Stirling engine).

The first engine has the ability to increase thermodynamic (indicator) efficiency by increasing the degree of expansion, making the power cylinder more pumping two or three times.

"Sterling" is the mechanical efficiency is higher than the motor with a crank mechanism (CRG) due to the fact that the reaction that occurs when converting translational motion into rotational made from the piston into the crossbar and is balanced at the opposite movement of the two rods. But both advantages are achieved by increasing the size of the engine.

The task of the invention is to improve engine efficiency while reducing the size of the engine.

The problem is solved at the expense of that is about, what multi-cylinder engine having a pump and power cylinders, interconnected gear camera, pistons, making simultaneous movement and rigidly connected with the rod, on the end of which is a crossbar with two fingers and put them rods, rotating towards each other, and the two synchronizing gears to pump and power cylinders added another power cylinder, working in a pair, which is formed by heating the water passing through the heat exchanger disposed in the transfer and exhaust chambers of the power cylinder.

The invention is illustrated by drawings, where figure 1 shows a diagram of the engine, figure 2 shows the gap crankshaft figure 3 - cross section of the cylinder block ⊘80 ⊘72 with a course of 80 mm and a ratio of water to fuel 5:1.

For clarity, made some deviations from drawing standards. In case 1, there are two power cylinder 2, four pumping cylinder 3 and two steam cylinder 4. They make reciprocating motion of the pistons 5, to which is rigidly attached to the rod 6. All rods are attached to the rod 7, having the form of a frame. In the frame sitting with the ability to rotate two fingers 8. The pins 8 mounted the rods 9. The rods are put on the knee 10 crankshaft 11, seated in the plug holders 12. At the ends of the shaft W is stco fixed timing gears 13. On the chassis 1 is mounted a cylinder head 14, which are two of the transfer chamber 15, each of which connects two of the pump cylinder with the one power, with them over the pumping cylinders are discharge valves 16 and over power - prom 17. In addition, above a pair of pump cylinders in one row, is the suction chamber 18 to the suction valve 19. Over power cylinders are exhaust cavity 20 with the exhaust valves 21. In the cavity 20 and the transfer chamber 15, where the valve 17, is the heat exchanger 22 through which water passes from the pump 23 and is directed into the compression chamber 24 of the steam cylinder, which is covered by the valve 25. Over a steam cylinder is the exhaust chamber 26 with the exhaust valve 27. From the chamber 26 is the channel 28 to the pump 23 through the cavity 29. The pump 23 has an adjusting screw 30, the loop line 31, the makeup water line 32 associated with fueling tank 33. For driving the pump on the crankshaft 11 includes a Cam 34, and the manual swap has a lever 35.

Between the rows of valve passes the Cam shaft 36, to which the pressed straight brackets 37 and 38 reverse. Straight bracket edges rests on two valves, and the opposite in the two flanges. One of the gear 13 is rigidly connected to the bevel gear 39 which is in engagement with a tapered neck is Terney 40, and this gear is rigidly seated on the same shaft with the gear 41. Parasitic gear 42 connects the gear 41 with the gear 43, which drives the shaft 36. To ignite the air-fuel mixture in the power cylinder installed glow plug 44. The flywheel can be installed on any one of the synchronizing gears 13.

Figure 2 shows the gap of the crankshaft. This means that he continues in another eight-cylinder unit in which the knee 10 deployed to 180°. When this synchronizing gears do not need to add. Blocks can be added (see figure 1) to the left or right of the synchronizing gears, catching between the neighbor. In this case, the secondary unit must have its own timing gears. You can combine both methods and then get a four-block, eight-cylinder in each engine with one wheel. Knee blocks in this case are shifted relative to each other by 90°. This engine will have a size of 720×600×500 (form almost a cube). In size he more Zhiguli just two times, and the working capacity of 10 times (12 liters, compared with 1.2 l) taking into account the fact that the efficiency will be higher than approximately twice the capacity of the proposed engine will be 20 times greater than that of the Zhiguli (≈1200 PS)

The engine works as follows.

When the movement of the piston 5 downward p is raised the valve 17, 19 and 25, and the Cam 34 on the shaft 11 pushes the plunger of the pump 23 up. This causes the process of air-fuel mixture in the suction chamber 18 of the carburetor (not shown), the process proceeds of the content of the transfer chamber 15 in the power cylinder 2 and the admissions process in the compression chamber 24 of the water from the heat exchanger 22. When reaching the pistons 5 of the bottom dead point, the valves 17, 19 and 25 are closed and the plunger pump 23 under the action of the spring begins to move down the exit from under the Cam 34. Open the valves 21, 16 and 27. This causes compression of the fuel-air mixture in the pump cylinders 3 and popping it in gear chamber 15, the process of expulsion of the contents of the power cylinder 2 through the exhaust cavity 20 into the atmosphere, the process of expulsion of the contents of the steam cylinder 4 through the discharge chamber 26 to line 28 where it enters the cavity 29. The glow plug 44 is always in working condition. The next time down motion of the pistons Cams repeat his command, and there are new processes.

In the power cylinder 2 is supplied compressed air-fuel mixture comes into contact with a candle 44 and ignite. Rapid combustion (approximately 0,002 sec). The temperature increases up to several thousand degrees, and the pressure about an order. Water passing through the heat exchanger, otura the t heat from the gases and heats itself. The temperature of the gases drops, and the water temperature increases, until at head. When the ratio of water to gasoline 5:1, this occurs at about 1000°.

The water pressure can rise up to 200-300 at. The vapor through the compression chamber 24 enters the steam cylinder 4 and presses the piston. Thus, while in the power cylinder 2, the piston pressure gases, and steam cylinder 4 - water vapor. A double stroke, creating a torque in all gears.

When the pistons will go back up in the pump cylinder 3 will be the next compression stroke, and in the power cylinder 2 is the first beat of the exhaust gas, steam cylinder 4 when this will occur during the pushing process of the mixture of steam and condensate in line 28. Condensation occurs due to the high degree of expansion (about 50).

At the next movement of the pistons has been repeated down the normal cycle. Thus, we get an engine that simultaneously uses two working body: the products of combustion and water vapor. With the help of an adjusting screw 30 can change the vapor pressure and the amount of heat taken away by the water, in a small range (20...50%).

Can a portion of the steam from the heat exchanger to pick up, then the design will work as a motor and as a heater.

It is possible to let all the steam used to heat the premises, then policitemii-boiler. Thus it is possible to increase the capacity of the pump, remove the steam cylinder and adjust the degree of expansion in the gas cylinder so that its capacity is only enough for the compressor and all remaining heat came on heating water. If the fuel use of a network gas, public utilities will receive the cheapest way of heating.

The proposed engine, among other things, can provide fuel savings of about 15% due to the fact that can operate at excess air, because the reliability of ignition it is ensured not high compression, as in a diesel engine, and the constant glow of the candles.

Multi-cylinder engine having a pump and power cylinders, interconnected gear camera, pistons, making simultaneous movement and rigidly connected with the rod, on the end of which is a crossbar with two fingers and put them rods, rotating towards each other, and the two synchronizing gears, wherein the pump and power cylinders added another power cylinder, working in a pair, which is formed by heating the water passing through the heat exchanger disposed in the transfer chamber and the exhaust cavity of the power cylinder.
