Referring to FIGS. 1 to 21, the cylinder block of the present invention is composed of a half body 1 and a half cylinder 2, and the present invention further includes a left shaft 3, a right shaft 4, a small ball 5, a connecting pin 6, a left piston plate 7, and a right The piston piece 8, the shaft angle adjusting device 9, and the like are configured, and the intake hole 10 and the exhaust hole 11, the ignition hole 12, and the automatic tempering groove 13 are formed in the cylinder. The semi-irid bodies 1 and 2 have two holes, and the center lines of the two holes pass through the center of the ball, and the angle between them is less than 180°. The two holes are used to position the rotating shaft, ensuring that the center line of the rotating shaft passes through the center of the ball after the rotating shaft is installed, and Ensure that the shaft can only make a rotary motion around its centerline. The top end of the left piston piece and the right piston piece are spherical surfaces, which are respectively matched with the inner spherical surfaces of the semi-carcass 1 and the semi-red body 2, and the bottom end is a spherical surface, and cooperates with the middle small sphere. A lubricating oil groove and a piston ring groove are formed on the spherical surface of the top and bottom end of the left/right piston piece for storing lubricating oil and installing a piston ring, respectively, to improve lubrication and sealing effect. After the rotating shaft is positioned on the cylinder block, ensure that the center line of the rotating shaft passes through the center of the ball, and the rotating shaft is coupled with the piston piece through the first coupling structure, and the spherical surface of the piston piece and the cylinder body and the spherical surface of the small spherical body are well matched. The first coupling structure on the rotating shaft can be evenly distributed on the rotating shaft or non-uniformly distributed. The left/right piston plates are connected by a connecting pin, and the center line of the connecting pin passes through the center of the ball, ensuring that the left/right piston piece can be flexibly rotated and sealed well around the center line of the connecting pin.

Solution A: The first coupling structure on the left/right rotating shaft is rotationally coupled by a positioning device using a connecting pin and a left/right piston plate, and the center line of all the positioning devices for positioning the piston plate on the rotating shaft passes through the center of the ball. After installing the piston plate, make sure that the center line of the connecting pin that positions the piston plate also passes through the center of the ball. In this example, six piston plates are mounted on each shaft, which is evenly distributed. A good seal is required between the connecting pin and the piston piece, and each flap can be flexibly rotated around the center line of the connecting pin.

Solution B: The first coupling structure on the left/right rotating shaft adopts a sliding groove and a left/right piston plate on the rotating shaft to realize a sliding connection, and the design of the sliding groove requires the assembly reference surface to pass through the center line of the rotating shaft, and the same is ensured. After the shaft and the piston piece are assembled, the assembly reference surface passes through the center line of the second coupling structure of the piston piece, that is, the plane formed by the center line of the rotating shaft and the center line of the second coupling structure of the corresponding piston piece after assembly. Coplanar with its assembly datum. In this example, there are 6 chutes on each rotating shaft, which are used to connect 6 piston plates. The 6 chutes are evenly distributed. After the piston plate is installed, the fit between the chute and the piston plate is ensured, and the seal is reliable. The sheet can be flexibly slid on the assembly plane or on the parallel plane of the assembly plane.

After installation, the center line of the left/right shaft is required to pass through the center of the ball; the center line of the connecting pin between the left/right piston pieces passes through the center of the ball; the spherical surface of the cylinder and the small sphere are in common; for the solution A, the positioning piston on the rotating shaft is also required. The center line of the connecting pin passes through the center of the ball.

The above structural design ensures that each adjacent pair of left/right piston plates and cylinders and the small spheres and the left/right rotating shafts form a working space, that is, a gas, when the left/right piston pieces rotate around the center of the ball, The left/right rotating shaft is driven to rotate correspondingly, and the center of the connecting pin between each pair of left/right piston pieces is in the same plane (see the plane A of FIG. 2 and FIG. 14 , and in the scheme B, an annular groove is also arranged on the small sphere). , used to define the center of the connecting pin between the left and right piston plates to make a rotational motion in the A plane) to make a rotational motion around the center of the ball. The left/right piston plates are rotated to different positions, and each cylinder volume changes accordingly. Each pair of pistons rotates around the center of the ball for a period of time, which will complete the process of changing the volume of the gas from maximum to minimum to maximum. In this case, there are 6 gas. The cylinder sequence alternates the above process. The cylinder block is formed with an air inlet hole, a vent hole, an ignition hole and an automatic tempering groove. When a gas has just started to vent through the maximum volume state (or an intermediate state), the previous cylinder starts to intake (it can also advance the intake air, so that there is a certain overlap between the fresh compressed air intake and the exhaust gas exhaust time. Try to drain the remaining exhaust gas from the previous work process, and then separately inject the fuel into the exhaust process. Then complete the compression, ignition, work, and exhaust phases. The current one cylinder continuously completes the intake, compression, ignition, and starts. During the work process, the next cylinder adjacent to the cylinder has just passed the minimum volume state, and the high temperature residual fire in the previous cylinder ignites the oil and gas mixed compressed gas in the latter cylinder through the automatic tempering tank to complete the ignition, avoiding each in the compressed state. It is necessary to use a spark plug to ignite and create superior ignition conditions for achieving lean combustion of mixed gas and gas.

A hole in the semi-red body 1 is expanded through the center of the ball, and a shaft angle adjusting device 9 is installed outside the semi-irid body 1 so that the angle 0 between the center lines of the two shafts can be adjusted in real time, that is, the maximum volume and single volume of the single cylinder are adjusted. The minimum volume of the cylinder, that is, during operation, the engine compression ratio and displacement can be adjusted in real time within a certain range to obtain better power performance and lower fuel consumption.

During operation, the left/right piston piece rotates around the center line of the second coupling structure. Each adjacent pair of left/right piston plates and cylinders and the small sphere and the left/right rotating shaft form a working space.

When the cylinder rotates around the center of the ball to different positions in the cylinder, its volume will change accordingly. Therefore, each cylinder rotates one week, and each engine is completed. Induction, compression, ignition and combustion, exhaust these processes, the rotation drive shaft, by converting thermal energy into mechanical shaft output.
