[0029] In a further optimized design, the first housing 1 has two openings 30, which are symmetrically arranged at the center, and the second housing 2 is installed at the openings 30.

[0030] Working process: An external starter motor drives one of the drive shafts 13 to rotate, which in turn drives the rotor 15 to rotate. The rotor 15 drives the first gear 14 to rotate, which in turn drives the second gear 12 to rotate. The second gear 12 drives the rotating column 25 to rotate via the driven shaft 10. Assuming the initial state, the sliding blade 16 is located at the protrusion, and the two working chambers are divided into chamber A and chamber B. In chamber A, air is introduced into chamber A through the air inlet 4, and atomized oil is introduced into chamber A through the oil injection hole 6. As the sliding blade 16 rotates, when the sliding blade 16 is about to pass the oil injection hole 6 and the air inlet 4, the oil injection hole 6 and the air inlet 4 are closed, and the sliding blade 16 continues to rotate. The sliding blade 16 approaches the other protrusion. At this time, the mixture of atomized oil and air is compressed as the space decreases. Subsequently, the compressed mixture of oil and air enters the air inlet 27 of the rotating column 25 through the first air passage 18 on the second housing 2 and is temporarily stored in the rotating column 25. The sliding blade 16 passes the protrusion and enters chamber B. The temporarily stored air-fuel mixture is ignited by the igniter in ignition port 5. The thrust enters chamber B through the second air passage 19, driving rotor 15 to rotate via sliding blade 16. Simultaneously, before sliding blade 16 rotates to the air inlet 4 and fuel injection port 6, air and fuel mist are introduced into chamber B through these ports. Just as sliding blade 16 is about to pass fuel injection port 6 and air inlet port 4, these ports close, and sliding blade 16 continues to rotate. As sliding blade 16 approaches another protrusion, the fuel is atomized. As the space decreases, the mixture of oil and air is compressed. Subsequently, the compressed oil and air mixture enters the air inlet 27 of the rotating column 25 through the first vent 18 on the second housing 2 and is temporarily stored in the rotating column 25. The sliding blade 16 enters the A chamber through the protrusion. The mixture temporarily stored in the rotating column 25 is ignited by the igniter in the ignition hole 5. The thrust enters the A chamber through the second vent 19 and drives the rotor 15 to rotate through the sliding blade 16. During this process, the exhaust gas is discharged through the exhaust hole 7.

[0031] In this invention, all components are made of existing materials and their strength meets the requirements of normal operation. The positions of the air intake 4, fuel injection 6 and exhaust 7 are all opened according to actual usage requirements and are not specifically limited. The ignition hole 5 is opened on the second housing 2 and the specific position is selected according to requirements and is not specifically limited.
