Rotating cylinder body; 10, worm fan gear; 11, swing groove; 12, eccentric roller; 13, main drive gear; 14, cam synchro gear; 15, high pressure oil pump; 16, oil seal; 17, power take-off shaft; 18, camshaft ;19, oil pump cam; 20, oil pump box; 21, main bearing seat; 22, gear box body; 23, worm shaft bearing seat; 24, IV working chamber; 25, fuel injector; 26, spark plug; 27, Fixed cylinder bump; 28, I working chamber; 29, fixed cylinder body; 30, exhaust hole; 31, compressed air passage; 32, rotating cylinder bump; 33, micro-scoring; 34, II working chamber; 35 , III working chamber; 36, air inlet;

Referring to FIG. 1 : the fixed cylinder 29 of the present invention uses the connecting bolt 6 to connect the gear box 22 through the intermediate partition plate 8 into one body. When the rotating cylinder runs counterclockwise, it drives the swing groove 11 to swing, and can directly output swing power. When the pendulum groove swings, the eccentric roller 12 fixed on the main transmission gear 13 drives the main transmission gear 13 to rotate in a single direction and outputs rotational power. At the same time, the synchronous gear 14 installed on the power output shaft 17 drives the camshaft 18. Rotate; drive the high-pressure oil pump 15 to work, and the generated high-pressure oil sprays atomized oil and gas into the working chamber regularly through the oil injection nozzle 25. The other end of the camshaft 18 drives the speed-increasing worm fan gear 10 to rotate; at the same time, the worm fan blade 2 is driven to rotate by the worm fan shaft 1 , so as to realize the boosting of the first-stage booster air chamber 3 .

See Figure 2: A-A-1. As shown in the figure: I; II; III; IV four working chambers are formed between the rotating cylinder 11 and the rotating protrusion 32 and the fixed cylinder 29 and the fixed cylinder protrusion 27; II; IV when the working chamber is at the end of compression In the state where the intake holes 36 and the exhaust holes 38 in the working chambers I and III are fully opened, and the exhaust gas is discharged, the spark plug is ignited, and the combustion mixture is combusted and expanded to work in the working chambers II and IV, which pushes the rotating cylinder block along the Clock rotation.

See Figure 3: A-A-2. As shown in the figure, the inlet and exhaust holes are completely closed at this time, and the fuel injectors of the I and III working chambers spray atomized oil and gas and start secondary compression.

See Figure 4: A-A-3. As shown in the figure, the inlet and exhaust holes of the working chambers II and IV are completely opened, and the first-stage compressed air presses the exhaust gas through the exhaust holes through the intake holes, and cools the intake air inside the cylinder at the same time. After the compression of the III working chamber is completed, the spark plug 26 is ignited at the left dead center position, and the I and III working chambers start to work and push the rotary cylinder to start to rotate counterclockwise. So go to the next work itinerary.

See Figure 5: A-A-4. The inlet and exhaust holes begin to close at the same time, the exhaust gas is completely discharged, and a small amount of the first-stage compressed air escapes from the exhaust hole, and at the same time acts as a cooling gas for the inner wall of the cylinder.

To sum up: 1. A working cavity is formed between the front and rear of the rotating cylinder block and the fixed cylinder block. The rotating cylinder rotates clockwise and rotates counterclockwise to complete a working cycle, which greatly saves money. The space improves the operation efficiency, so theoretically speaking, the volume and mass of the present invention are only 1/4 and 25% of that of the traditional engine for an engine of the same power. 2. The intake and exhaust of each working chamber are automatically realized, without the need for a separate gas distribution system, which greatly simplifies the structure and improves the working reliability; 3. Because the rotating cylinder body and the fixed cylinder body of the present invention have large coverage and are subjected to force and heat Uniform and small deformation, therefore, based on the modern fluid dynamic pressure lubrication theory, special shallow grooves 33 are engraved on specific parts of the rotating parts and stationary parts, and the compressed air flowing through the compressed air passage 31 and the intake holes is assisted; the engine is running At the same time, turbulent flow and air film are formed between the sealing surfaces to realize non-contact dynamic sealing and non-abrasive sealing operation.

See Figure 6: B-B-1. As shown in the figure, the pendulum groove 11 is at the top dead center position. When the rotating cylinder works, it rotates counterclockwise, which drives the pendulum groove to swing counterclockwise, and the upper left end drives the eccentric roller 12 integrated with the left transmission gear 13 to drive the left The transmission gear rotates and drives the main transmission shaft clockwise to output rotational torque through the right transmission gear meshed with it.

See Figure 7: B-B-2. As shown in the figure, the pendulum groove 11 is at the midpoint of the stroke and continues to drive the transmission point wheel to rotate in the original direction.

See Figure 8: B-B-3. As shown in the figure, the swing groove 11 is at the bottom dead center position at this time.

See Figure 9: B-B-4. As shown in the figure, the rotating cylinder starts to rotate clockwise at this time, which drives the side of the swing groove to swing clockwise, and the upper right end drives the eccentric roller integrated with the right main transmission gear to drive the right main transmission gear to rotate and output directly through the main transmission shaft. Rotate torque clockwise.

From the above B-B-1; B-B-2; B-B-3; B-B-4; it can be seen that ① through the swing groove, not only the rotary reciprocating motion of the rotary cylinder is converted into the one-way rotary motion of the main drive gear, but also from the beginning to the In the end, it has a large output torque. In theory, its effective output torque is more than 2 times that of the transmission engine, which completely overcomes the traditional engine. ② Since the swing groove works by relying on the upper parts of the left and right ends of the swing groove to play their roles in sequence, the rotating cylinder of the present invention can still work normally when it is slightly smaller than the designed maximum stroke, that is, it can realize variable stroke work within a certain range. This not only makes it easier to start the engine, but also realizes the position of the spark plug and the dual control of the speed of ignition, and seeks the best timing for ignition to maximize the efficiency of energy transfer.
