Detailed ways

Below in conjunction with accompanying drawing, the embodiment of the present invention is described further:

It can be seen from Fig. 1 and Fig. 2 that the output shaft 14 and the back pressure vane shaft 7 are fixed on the engine block 1 through bearings. Inlet solenoid valve 4, fuel injector 5 and spark plug 6 are installed on one side of the annular cylinder 9 wall at 0°～45° counterclockwise with back pressure vane disc 18, and at 135 counterclockwise with back pressure vane disc 18 A sprinkler 15 is installed on the side surface of the annular cylinder wall of °～215 °, and an exhaust hole 17 is arranged on the side surface of the annular cylinder wall of 0 °～45 ° clockwise with the back pressure vane disc 18. The annular cylinder 9 is fixed on the engine block 1 and is sleeved on the output shaft 14 through the lower secondary seal; the rotating blade 6 is fixed on the output shaft 14 through a key and is in close contact with the annular cylinder; the driving wheel 13 of the bead chain transmission mechanism is passed through the key Fixed on the output shaft 14, the driven wheel 8 and the back pressure blade disc 18 are fixed on the back pressure blade shaft 7 through keys, the bead chain 10 starts from the driving wheel 13, and drives the driven wheel 8 through the bead chain tightening guide wheel 12 , and then return to the driving wheel 13 through the loose edge guide wheel 11 of the bead chain. The function of the chain transmission mechanism is to ensure that the rotating blade 16 and the back pressure blade disc 18 are driven strictly according to 1:1, so that the rotating blade 16 is transferred to the back pressure blade disc. During the position of 18, the gap on the back pressure vane disc 18 just in time makes the rotary vane 16 pass. The back pressure vane disc 18, the rotating vane 16 and the annular cylinder 9 form an annular combustion chamber, and the average length of the annular combustion chamber is about twice as large as the engine piston stroke length of the same size.

As can be seen from Fig. 3, the air intake system is formed by the air filter 2, the air compressor 3, the intake solenoid valve 4 and the intake pipe 22, and the water tank 21, the high-pressure water pump 20, the flow control valve 19 and the sprinkler 15 are composed sprinkler system.

The working process of the engine is described as follows: when the engine is working, the air compressor 3 works to compress the outside air through the air filter 2 into high-pressure gas, and the high-pressure water pump 20 pressurizes the water in the water tank 21 into high-pressure water. When the clock hand turns the intake solenoid valve 4, the intake solenoid valve 4 and the fuel injector 5 are opened, and the high-pressure gas and fuel enter the annular cylinder 9 to form a mixed gas; when the amount of mixed gas is sufficient, the intake solenoid valve 4 and the fuel injection valve are closed. At the same time, the spark plug 6 is ignited, and the expanding gas pushes the rotating blade 16 to rotate; when the rotating blade 16 turns over the position of the sprinkler 15, the flow control valve 19 is opened, so that the sprinkler 15 sprays an appropriate amount of high-pressure water into the annular cylinder 9 Fog, water mist absorbs the heat of gas and suddenly turns into water vapor (volume expansion is more than 1700 times), and continues to push the rotating blade 16 to rotate, and the output shaft 14 does work externally; after the rotating blade passes through the exhaust hole 17, the waste gas and water in the annular cylinder 9 The steam is discharged out of the engine through the exhaust hole 17 through the exhaust pipe 23 . Because the rotating vane 16 and the back pressure vane disc 18 are driven by 1:1, when the rotating vane 16 turned to the position of the back pressure vane disc 18, the gap on the back pressure vane disc 18 just let the rotating vane 16 pass. The engine completes a working process like this.

After the rotating blade 16 turned over the position of the sprinkler 15, the gas pressure in the annular cylinder 9 dropped very much according to the hyperbolic law, but at this moment the temperature of the annular cylinder 9 and its internal gas was still above 1,000 degrees. The surface area of the mist is large, and it can be vaporized into water vapor when it contacts with high-temperature gas, and the volume expands more than 1700 times. A proper amount of water mist is sprayed into the annular cylinder 9 to make the water mist expand suddenly and increase the pressure of the gas in the annular cylinder 9. Continue to push the rotating blade 16 to rotate along the circumferential direction. With this method, the heat energy of thousands of degrees of lower pressure gas and thousands of degrees of annular cylinder 9 is converted into water vapor of hundreds of degrees, which not only makes full use of energy, but also reduces the temperature of annular cylinder 9, saving The water cooling system of the engine.
