The engine presses air into the fixed combustion chamber from the compressor, and at the same time presses the air into the pump chamber of the high-pressure pump. The piston of the high-pressure pump compresses the air in the pump chamber, and then pressurizes the fixed combustion chamber. When the pressure is high, the intake valve closes, the fixed combustion chamber injects fuel, ignites, and explodes. At this time, the upper dynamic combustion chamber just reaches this position in turn, and the thrust of the fuel explosion in the fixed combustion chamber pushes the rotor to rotate to achieve one-time work. After the combustion is completed, the intake valve opens, and new air enters the fixed combustion chamber. The last groove on the rotor is used as a scavenging chamber, and the remaining exhaust gas in the fixed combustion chamber is swept out by the fresh air and discharged into the groove.

As shown in FIG. 1 , a disc wheel rotor 1 is rotatable in a housing 3 , and 20 is a rotating shaft. The two air inlets of the constant combustion chamber 12 are provided with air intake valves 7 and 10, the air intake pipe 11 communicates with the outlet of the compressor 13, and the other air intake pipe 6 communicates with the outlet of the high-pressure pump 5, the labels 8 and 1 among Fig. 1 9 represent the fuel injector and the spark plug respectively; the high-pressure pump 5 is provided with a piston 4, and the outlet 12-1 of the fixed combustion chamber communicates with the shell. The outer arc surface of the rotor 1 has grooves, the first three grooves 18 are dynamic combustion chambers, and the last groove 18' is a scavenging chamber. During work, the compressor 13 fills air into the fixed combustion chamber 12 and the pump chamber of the high-pressure pump 5 at the same time, and then with the movement of the piston 4, the air in the pump chamber is further pressed into the fixed combustion chamber to pressurize the fixed combustion chamber. High enough, after the intake valve of the fixed combustion chamber is closed, the fuel is injected and ignited. At this time, the rotation of the rotor 1 just makes the dynamic combustion chamber 8 reach the position 12-1 and communicates with the fixed combustion chamber 12 in turn; the explosive force generated by the expansion gas of fuel combustion produces a tangential thrust on the rotor through the groove, and pushes the rotor to do work. When the combustion is completed, the groove 18' of the scavenging chamber reaches the position of 12-1, and the remaining exhaust gas in the fixed combustion chamber is discharged into this groove and transported away. When the groove reaches the exhaust port 16, the exhaust gas in the groove is sucked out and discharged by the turbine 17 . The fresh air continues to be charged into the constant combustion chamber to start the operation of the next cycle, so that the work is continuously circulated. The shell 3 is provided with a cooling water channel 3, and the water pump continuously feeds cold water to cool the shell. The filler port 14 can be connected with the oil pot 15 to add lubricating oil to the rotor.

The rotor 1 and the housing 3 are in contact with each other through an expansion ring 23 . It is installed around the notch of each groove of the rotor, around the fixed combustion chamber outlet 12-1 of the casing, the exhaust port 16, and the filler port 14, and it plays the role of sealing and reducing friction. Fig. 2 and Fig. 3 show the installation method of the expansion ring 23 at the groove 18, there is an expansion spring groove 22 around the groove 18, and the wave reed surface and the expansion ring 23 are successively loaded into the groove, (see Fig. 3 ), The corrugated reed 24 pushes up against the expansion ring 23 to ensure that the upper end surface of the expansion ring is tightly pressed against the shell (see Figure 2) to achieve a sealing effect.
