Description

Technical Field

[0001] The present invention relates to an internal combustion engine of an internal combustion technology type, which generates high-temperature and high-pressure expansion gas by exploding and burning fuel and compressed air in a combustion chamber, and then converts the high-temperature and high-pressure expansion gas into mechanical power. Background Art

[0002] Existing internal combustion engines adopting the Otto cycle, including reciprocating piston engines, Wankel engines, and gas turbines, all work by burning a combustible compressed mixture in a cylinder to generate high-temperature and high-pressure expansion gas, and pushing a piston or a rotor and its connected components to produce mechanical motion, thereby converting chemical energy into mechanical energy.

[0003] The working principle of a reciprocating piston engine is that fuel burns in a closed cylinder to generate high-temperature and high-pressure expansion gas, which pushes the piston to make a reciprocating linear motion. The connecting rod and the crankshaft convert the reciprocating linear motion of the piston into the rotational motion of a flywheel to achieve energy conversion and output. The disadvantages of a reciprocating piston engine are high vibration intensity, low energy conversion rate, and fuel waste. The working principle of a Wankel engine is that a triangular rotor divides the inner cavity of an elliptical cylinder into three independent combustion chambers. The triangular rotor rotates eccentrically in the elliptical cylinder, causing the volumes of the three independent combustion chambers in the elliptical cylinder to change continuously, thereby realizing the four strokes of intake, compression, power generation, and exhaust. The disadvantages of a Wankel engine are low compression ratio, incomplete combustion, low energy conversion rate, and high fuel consumption. The working principle of a gas turbine is that a compressor sucks in air and compresses it step by step. The compressed air enters the combustion chamber and mixes with the injected fuel to burn and generate high-temperature and high-pressure gas. Then, these high-temperature and high-pressure gases enter the turbine to expand and do work. The disadvantages of a gas turbine are complex structure, low energy conversion rate, high cost, and high noise.

[0004] CN111472887A discloses a rack piston type internal combustion engine technology. A rack is installed at one end of the piston of a traditional internal combustion engine away from the cylinder, and power is transmitted from the rack to a power output shaft. Although this increases the power transmission efficiency, it still does not change the technical disadvantages of high vibration intensity and low energy conversion rate.

[0005] CN118775056A discloses a gas turbine technology with a high-pressure ratio and high-flow structure. The gas turbine technology includes a compressor and a combustion chamber. A servo motor is installed at the top of the compressor, and a bevel gear is installed at the output end of the servo motor. The bevel gear meshes with a bevel gear disk. The disadvantages of this structural technology are high cost, low energy conversion rate, and high noise of the gas turbine.

[0006] CN118979810A discloses a three-dimensional synchronous machine, which combines the advantages of steam engines, internal combustion engines, and gas turbines. However, it contains piston connecting rod crankshaft structure technology, and its disadvantages are that this three-dimensional synchronous machine has high vibration intensity, low energy conversion rate, and fuel waste. Summary of the Invention

[0007] (1) Technical problems to be solved

[0008] The present invention aims to solve the technical problems of high vibration intensity, low energy conversion rate, and complex structure of existing engines, and provides a stable, efficient, and energy-saving engine with stable vibration, simple structure, low cost, and high energy conversion rate compared with the prior art.

[0009] (2) Technical solutions

[0010] To solve the above problems, the present invention provides a cylindrical main rotating shaft series integrated engine device, characterized in that in the engine device of the present invention, there are a gas distributor, a gas pushing burner, a cylindrical main rotating shaft, a working cylinder, a compression cylinder, an auxiliary cylinder, a flat fan-shaped rotary plug, a grid plate base, and a grid plate. The three cylinders of the working cylinder, the compression cylinder, and the auxiliary cylinder have different specifications and dimensions, but the technical structures and shapes are the same. Inside each cylinder including the working cylinder, the compression cylinder, and the auxiliary cylinder, a flat fan-shaped rotary plug is installed, and a grid plate base and a grid plate are installed outside each cylinder; and only a gas pushing burner is additionally installed outside all the working cylinders, and only a gas distributor is additionally installed outside the compression cylinder.

[0011] The compression cylinder can be provided with multiple compression cylinders according to actual needs. In the specific embodiment of the present invention, only one compression cylinder is provided.

[0012] The working cylinder is limited by an even multiple of the number of compression cylinders. According to the number of compression cylinders, an even multiple of two times, four times, or six times the number of working cylinders can be provided. In the specific embodiment of the present invention, four working cylinders are specifically provided, namely the first working cylinder, the second working cylinder, the third working cylinder, and the fourth working cylinder. The technical structures, shapes, and specifications of the four working cylinders are the same.

[0013] The auxiliary cylinder is limited by an even multiple of the number of compression cylinders. According to the number of compression cylinders, an even multiple of two times or four times the number of auxiliary cylinders can be provided. In the specific embodiment of the present invention, two auxiliary cylinders are specifically provided, namely the left auxiliary cylinder and the right auxiliary cylinder. The technical structures, shapes, and specifications of the two auxiliary cylinders are the same.

[0014] All the cylinders mentioned above, including each cylinder such as the compression cylinder, the working cylinder, and the auxiliary cylinder, are composed of a composite cylinder, a left end cover, and a right end cover. The left end cover and the right end cover are installed at the left and right end face parts of the composite cylinder. The shapes, structures, and dimensions of the left end cover and the right end cover of each cylinder are the same. Inside the left end cover and the right end cover, there are bushings, shaft holes, and end cover cooling water chambers, end cover water inlet ports, and end cover water outlet ports for cooling purposes. The left end cover and the right end cover are installed with water sealing plates for sealing the end cover cooling water chambers. Each composite cylinder is provided with grid plate slots, cylinder air inlets, cylinder air outlets, a left platform for installing the left end cover, a right platform for installing the right end cover, a circular plate platform for installing the circular water sealing plate, a circular platform for strengthening the stress intensity of the composite cylinder, a cylinder cooling water chamber for cooling purposes, a cylinder water inlet port, and a cylinder water outlet port.

[0015] The gas distributor mentioned above is provided with a distributor check valve, a distributor air inlet, a distributor "Y"-shaped outlet pipe, and a pressure regulating valve. The air inlet of the gas distributor is connected to the air outlet of the composite cylinder of the compression cylinder. The gas distributor has a total of two "Y"-shaped outlet pipes on the left and right. Each "Y"-shaped outlet pipe has two single ports. The gas distributor has a total of four single ports, which are respectively connected to the air storage chamber air inlets of the air pushing burners installed on the upper parts of the four working cylinders.

[0016] The push-air burners installed on the upper parts of the four working cylinders all have the same technical structure, shape, and specification dimensions. The push-air burner is provided with an air storage chamber, a combustion chamber, a spark plug, an oil injector, a left push rod, a right push rod, a left rocker arm, a right rocker arm, a left valve, a right valve, a push valve, a left timing cam, a right timing cam, an oil inlet of the push-air burner, an oil outlet of the push-air burner, a vent port, a water inlet pipe port of the push-air burner for cooling, a water outlet pipe port of the push-air burner, and a water channel of the push-air burner. The right valve has the same shape as the left valve, but the rod length of the right valve is slightly shorter than that of the left valve by 4 mm, so that the stroke of the right valve and the left valve pushed by the left rocker arm is equal. Both the right valve and the left valve are composed of a rod head, a rod body, and a tail frame. Among them, the rod head and the rod body are integrally fixed together, and the rod body and the tail frame are tightened together with screws. The tail frame is provided with a rectangular frame hole. After the right rocker arm passes through the frame hole, it ensures that the right valve, the left valve, and the right rocker arm do not contact each other during operation. The vent port can reduce the air resistance and negative pressure behind the pushing surface when the push valve works, and the vent port also has the function of discharging oil. The air storage chamber is provided with an air storage chamber check valve, an air inlet of the air storage chamber, and an air outlet of the air storage chamber. The combustion chamber is provided with an air inlet of the combustion chamber and an air outlet of the combustion chamber. The air inlet of the air storage chamber is connected to a single port of the "Y"-shaped outlet pipe of the distributor on the compression cylinder, the air outlet of the air storage chamber is connected to the air inlet of the combustion chamber, and the air outlet of the combustion chamber is connected to the air inlet of the composite cylinder of the working cylinder. The air inlet of the composite cylinder of the left auxiliary cylinder in the two auxiliary cylinders is connected to the air outlet of the composite cylinder of the first working cylinder and the air outlet of the composite cylinder of the second working cylinder; the air inlet of the composite cylinder of the right auxiliary cylinder in the two auxiliary cylinders is connected to the cylinder outlet of the composite cylinder of the third working cylinder and the cylinder outlet of the composite cylinder of the fourth working cylinder.

[0017] For each cylinder among all the cylinders described above, the installed flat sector rotary plugs, baffle plates, and baffle plate bases have the same structural shape although their specification dimensions are not exactly the same.

[0018] The described baffle plate base is installed at the baffle plate slot of the composite cylinder of the corresponding cylinder. The baffle plate base is provided with a base water inlet pipe port for cooling, a base water outlet pipe port, a base cooling water channel, a base oil channel, a base oil inlet pipe, a base oil outlet pipe, a front sealing door, and a rear sealing door. The front sealing door and the rear sealing door have the same shape, specification, and dimensions.

[0019] The described baffle plate is installed inside the baffle plate base. A spring is installed inside the baffle plate base. Under the pressure of the spring, the baffle plate tightly presses against the flat sector rotary plug inside the composite cylinder. The baffle plate is fixedly composed of a round handle and a long plate. On both sides of the long plate part, left and right sealing plates are provided. In the middle of the long plate part, a long plate oil hole is provided. The bottom end of the long plate part is set in an inclined arc shape. The inclined arc surface is used to ensure that when the baffle plate is pushed by the lifting arc surface of the flat sector rotary plug, it can move up and down flexibly, and make the baffle plate fit tightly with the flat sector rotary plug without air leakage. The left and right sealing plates provided on both sides of the baffle plate are the same in shape as the sealing plates provided on the flat sector rotary plug. The oil inside the baffle plate base can enter the oil hole of the baffle plate. The front sealing door, rear sealing door inside the baffle plate base and the left and right sealing plates of the baffle plate enable the baffle plate installed inside the baffle plate base to fit tightly with the inner wall of the baffle plate base and slide up and down, effectively preventing the high-pressure gas inside the composite cylinder from leaking from the slot holes of the baffle plate. There is both relative flexible movement and good sealing performance among the baffle plate base, the baffle plate, the composite cylinder and the flat sector rotary plug.

[0020] The described flat sector rotary plug is provided with a shaft hole. The contour of the flat sector rotary plug is in a fan-shaped structure shape, which is divided into four parts: a lifting arc surface part, a far stop push arc surface part, a playback arc surface part, and a near stop push arc surface part. The curvature radius of the arc surface of the far stop push arc surface part is equal to the curvature radius of the inner cavity circular hole surface of the composite cylinder. The length of the far stop push arc surface of the flat sector rotary plug is set to be more than four times the diameter width of the air inlet on the composite cylinder of the working cylinder. With this technical feature, it is ensured that during each rotation of the flat sector rotary plug past the air inlet of the composite cylinder, its far stop push arc surface part can perform a dynamic short-term closing function on the air inlet of the composite cylinder of the working cylinder, so as to facilitate the compressed air introduced into the combustion chamber not to leak or decompress in a short period and fully mix and burn with the fuel.

[0021] The described flat sector rotary plug is installed inside the composite cylinder of the corresponding cylinder. The two side surfaces and the far stop push arc surface part of the flat sector rotary plug respectively fit tightly and can rotate flexibly with the left end cover and the right end cover installed inside the composite cylinder and the inner wall curved surface of the composite cylinder. When the flat sector rotary plug rotates inside the composite cylinder and touches and pushes the baffle plate during the encounter, it is the lifting arc surface part of the flat sector rotary plug that pushes the baffle plate up to the upper part of the inner cavity curved surface of the composite cylinder, opening the rotation path of the flat sector rotary plug. After the flat sector rotary plug passes, the baffle plate falls back under the pressure of the spring.

[0022] The described flat sector rotary plug is provided with two rows of sealing plates at the far stop push arc surface part and the left and right side surface parts. Each row of sealing plates has two left and right sealing plates. The sealing plates are installed in the grooves, and springs are installed in the grooves to exert elastic force on the sealing plates. Oil holes are provided at the far stop stroke arc surface part and the left and right side surface parts of the flat sector rotary plug, and tiny oil holes are provided in the grooves.

[0023] During the rotation of the flat-sector rotary plug within the composite cylinder, the flat-sector rotary plug and the baffle plate always divide the inner cavity of the composite cylinder into two different types of conditions: one type of condition is that the air inlet and the air outlet of the composite cylinder are not connected, and the other type of condition is that the air inlet and the air outlet of the composite cylinder are connected to each other. These two conditions occur in a cycle of yin-yang waxing and waning, enabling the intake, compression working stroke of the flat-sector rotary plug in the compression cylinder of the present invention and the working stroke of the flat-sector rotary plug in the working cylinder for work and exhaust to proceed synchronously and continuously. Along the rotation direction of the flat-sector rotary plug: (1) When the baffle plate in the composite cylinder of the compression cylinder and the flat-sector rotary plug cause the air inlet of the composite cylinder and the air outlet of the cylinder not to be connected, while the flat-sector rotary plug sucks air into the compression cylinder from the air inlet of the composite cylinder, it also presses gas into the gas distributor from the air outlet of the composite cylinder. And when the air inlet of the composite cylinder of the compression cylinder and the air outlet of the cylinder are connected to each other, the intake and compression working stroke of the flat-sector rotary plug in the compression cylinder ends. (2) When the baffle plate in the composite cylinder of the working cylinder and the sector rotary plug cause the air inlet of the cylinder and the air outlet of the cylinder not to be connected, the high-pressure gas from the combustion chamber rushes into the cavity between the flat-sector rotary plug and the baffle plate in the composite cylinder of the working cylinder. The flat-sector rotary plug is pushed by the high-pressure gas to rotate and do work. At the same time, the flat-sector rotary plug also sweeps the waste gas along the way out of the air outlet of the cylinder. And when the air inlet of the cylinder and the air outlet of the cylinder are connected to each other, the high-pressure gas inside the composite cylinder of the working cylinder is discharged from the air outlet of the cylinder, and the working stroke of the flat-sector rotary plug in the working cylinder for work and sweeping the waste gas ends. (3) The working stroke of the baffle plate and the flat-sector rotary plug in the composite cylinder of the two auxiliary cylinders is carried out continuously with the working stroke of the baffle plate and the sector rotary plug in the composite cylinder of the above-mentioned working cylinder. When the rotation and exhaust stroke of the flat-sector rotary plug in the composite cylinder of the working cylinder end, the air inlet of the cylinder in the auxiliary cylinder is connected to the gas discharged from the air outlet of the cylinder, continuously pushing the flat-sector rotary plug in the auxiliary cylinder to rotate and do work. And when the flat-sector rotary plug in the composite cylinder of the working cylinder starts to rotate and do work again, the rotation and work stroke of the flat-sector rotary plug in the auxiliary cylinder ends, and only the exhaust stroke follows.

[0024] The engine of the present invention described above has only one cylindrical main rotating shaft as a whole. The main rotating shaft passes through the left end cover shaft sleeve, the right end cover shaft sleeve, and the shaft holes of the flat sector plugs in the composite cylinder of each cylinder including the working cylinder, the auxiliary cylinder, and the compression cylinder. Each flat sector plug installed in series in each cylinder on the main rotating shaft is fixedly installed on the main rotating shaft with a flat key. The timing cams of each air-pushing burner are fixedly installed on the main rotating shaft with a flat key to provide thrust for timing the push rods and rocker arms outside the working cylinder. A flywheel and a pulley are also installed on the main rotating shaft. Finally, the frontmost and rearmost ends of the main rotating shaft pass through the engine housing shaft sleeve and are installed on the engine housing of the present invention. There are oil holes on the engine housing shaft sleeve. Thus, by using one cylindrical main rotating shaft, all the cylinders of the present invention and the accessories installed inside and outside the cylinders are installed in series as a whole.

[0025] The main rotating shaft is provided with a central axis oil passage and radial oil holes. The central axis oil passage of the main rotating shaft is connected to the radial oil holes, the engine housing shaft sleeve oil holes, and the flat sector plug oil holes.

[0026] The phase relationship among the working cylinder, the auxiliary cylinder, and the compression cylinder installed in series on the main rotating shaft in the apparent plane is as follows: With one compression cylinder at the center position of the main rotating shaft, an equal number of working cylinders and auxiliary cylinders of the same specification size are installed symmetrically on both sides of it. All the cylinders of the present invention are installed in series on the main rotating shaft. Taking one compression cylinder as the center, the specific conditions of the cylinders installed symmetrically on both sides of it, in the order from left to right, are: the first working cylinder, the second working cylinder, the left auxiliary cylinder, the compression cylinder, the right auxiliary cylinder, the third working cylinder, and the fourth working cylinder.

[0027] The phase relationship among the flat sector plugs installed in series in each cylinder on the main rotating shaft of the present invention in the apparent plane is as follows: The far stop push arc surface of the flat sector plug contour in the first working cylinder faces upward, the far stop push arc surface of the flat sector plug in the second working cylinder faces downward, the far stop push arc surface of the flat sector plug contour in the left auxiliary cylinder faces downward, the far stop push arc surface of the flat sector plug contour in the compression cylinder faces upward, the far stop push arc surface of the flat sector plug contour in the right auxiliary cylinder faces downward, the far stop push arc surface of the flat sector plug contour in the third working cylinder faces downward, and the far stop push arc surface of the flat sector plug contour in the fourth working cylinder faces upward. The technical feature of this layout can ensure that the centrifugal forces of the flat sector plugs in the four working cylinders cancel each other out during rotational motion; ensure that the rotational centrifugal force of the flat sector plug in the compression cylinder cancels out the centrifugal forces among the flat sector plugs in the left auxiliary cylinder and the right auxiliary cylinder, so as to reduce the engine vibration intensity.

[0028] When the engine device of the present invention is working, the flat-sector rotary plugs in the four working cylinders, the flat-sector rotary plugs in the compression cylinder, and the flat-sector rotary plugs in the two auxiliary cylinders rotate synchronously on the same main rotating shaft. The flat-sector rotary plug in the compression cylinder sucks air into the compression cylinder on one side and compresses the air into the gas distributor on the other side. The gas distributor inputs the compressed high-pressure air into the air storage chambers of the air-pushing burners on each working cylinder through the "Y"-shaped outlet pipe. At this time, the air-pushing valves, left valves, and right valves of each air-pushing burner do not move, and the air passage between the air outlet of the air storage chamber and the air inlet of the combustion chamber is closed. The closing effect of the right valve on the air passage connected to the air outlet of the air storage chamber prevents the compressed air in the air storage chamber from prematurely flowing into the air passage connected to the air inlet of the combustion chamber, thus flushing open the left valve and causing an air leakage effect. When the working stroke of inputting compressed air into the air storage chamber ends, the air inlet of the air storage chamber is closed by the one-way valve, preventing the compressed air in the air storage chamber from flowing back to the distributor. Further, then, the left push rod, right push rod, left rocker arm, and right rocker arm outside each working cylinder are pushed by their respective timing cams to push the left valve, right valve, and air-pushing valve on the air-pushing burner, open the exhaust port of the air storage chamber, and open the air inlet of the combustion chamber, pushing the compressed air into the combustion chamber. At the same time, the arc surface N-R section from point N to point R of the far stop stroke arc surface of the flat-sector rotary plug in each working cylinder exactly closes the composite cylinder air inlet and the combustion chamber exhaust port of the cylinder. Further, when the left valve and the right valve are reset and close the air inlet passage above the combustion chamber, shortly after, the air-pushing valve is reset, the fuel injector injects fuel into the combustion chamber to form a combustible mixture, the spark plug emits a spark, and the combustible mixture burns to generate high-temperature and high-pressure gas. At this time, the far stop push arc surface of the rotating flat-sector rotary plug in the working cylinder exactly rotates completely through the composite cylinder air inlet of the cylinder, opening the composite cylinder air inlet and the combustion chamber exhaust port of the cylinder. The high-temperature and high-pressure gas simultaneously rushes towards the flat-sector rotary plug and the baffle plate. Since the high-temperature and high-pressure gas cannot push the baffle plate and the baffle plate has good sealing performance, the high-temperature and high-pressure gas pushes the flat-sector rotary plug, the main rotating shaft, and the flywheel to rotate and do work. At the same time, as the flat-sector rotary plug rotates, the temperature and pressure of the high-temperature and high-pressure gas also gradually decrease. When the flat-sector rotary plug rotates past the composite cylinder air outlet of the cylinder, the high-temperature and high-pressure gas after cooling and pressure reduction is discharged through the composite cylinder air outlet and enters the auxiliary cylinder to further exert a thrust on the flat-sector rotary plug in the auxiliary cylinder.Among them, the high-temperature and high-pressure gas after temperature reduction and pressure reduction discharged from the air outlet of the composite cylinder of the first working cylinder and the high-temperature and high-pressure gas after temperature reduction and pressure reduction discharged from the air outlet of the composite cylinder of the second working cylinder enter the left auxiliary cylinder, further exerting a thrust on the flat sector rotary plug in the left auxiliary cylinder; the high-temperature and high-pressure gas after temperature reduction and pressure reduction discharged from the air outlet of the composite cylinder of the third working cylinder and the high-temperature and high-pressure gas after temperature reduction and pressure reduction discharged from the air outlet of the composite cylinder of the fourth working cylinder enter the right auxiliary cylinder, further exerting a thrust on the flat sector rotary plug in the right auxiliary cylinder. Finally, the high-temperature and high-pressure gas whose temperature and pressure have dropped to a lower level is discharged as waste gas from the air outlet of the left or right auxiliary cylinder, enters the collecting filter chimney, is purified and then discharged into the atmosphere. The residual oil droplets in the waste gas flow back into the oil pan after being filtered, and the fine particles are separated, collected and removed regularly. During the whole working process, starting from compressing air in the compression cylinder, to the combustion of the combustible mixture to generate high-temperature and high-pressure gas to push the flat sector rotary plug, the main rotating shaft and the flywheel to rotate and do work, and finally the waste gas is discharged after being filtered by the collecting filter chimney, which is a complete working cycle. The collecting filter chimney is installed at the bottom of the machine shell for discharging waste gas. The collecting filter chimney is provided with a filtering chamber, a sedimentation cup and a filtering cup, which can effectively filter and collect the residual oil droplets and fine particles mixed in the waste gas. The residual oil droplets flow back into the oil pan after being filtered, and the fine particles are collected and removed regularly. A pressure regulating valve with the function of a safety valve is provided on the gas distributor outside the compression cylinder, and the pressure of the high-pressure gas in the gas distributor can be adjusted according to different technical requirements.

[0029] The engine technical device of the present invention has a compression cylinder that undertakes the intake and compression working strokes of air, and inputs the compressed air into the combustion chamber through a gas distributor and a gas storage chamber; a working cylinder undertakes the working and exhaust working strokes of the high-temperature and high-pressure gas after combustion. Therefore, during the operation of the engine device of the present invention, the four working strokes of intake, compression, working, and exhaust are carried out synchronously. The suction and compression functions of the compression cylinder and the working and exhaust functions of the working cylinder are independent of each other. The specifications and dimensions of the composite cylinder and the flat-sector rotary plug of the compression cylinder, as well as the specifications and dimensions of the combustion chamber, can be set as required. Since the specifications and dimensions of the composite cylinder and the flat-sector rotary plug of the compression cylinder determine the size of the effective working volume of the compression cylinder; the specifications and dimensions of the combustion chamber determine the size of the effective working volume of the combustion chamber, and the ratio of the effective working volume of the compression cylinder to the effective working volume of the combustion chamber is the compression ratio of the engine device of the present invention. Therefore, the engine device of the present invention can achieve a larger compression ratio. In addition, the left auxiliary cylinder and the right auxiliary cylinder in the engine device of the present invention, as well as the flat-sector rotary plugs inside them, can be replaced by two left counterweight iron blocks and two right counterweight iron blocks with the same shape and weight respectively. During operation, the high-temperature and high-pressure gas after cooling and pressure reduction discharged from the air outlets of the first working cylinder, the composite cylinder of the second working cylinder, the third working cylinder, and the fourth working cylinder directly enters the collecting and filtering chimney and is discharged into the atmosphere after purification. With this technical measure, it is ensured that the engine device of the present invention can be applicable to the technical characteristics of small-power models.

[0030] The engine device of the present invention also installs a fuel supply system, an air supply system, a centrifugal governor, a flywheel energy storage, a lubrication system, a battery ignition system, and a cooling water circulation system outside or inside the engine housing respectively. These technologies are now public and do not need to be described in detail.

[0031] Compared with the existing engine technologies, since the present invention uses a gas-pushing burner, a distributor, a working cylinder, an auxiliary cylinder, a compression cylinder, a flat-sector rotary plug, a baffle plate, and a main rotating shaft to work, it does not need to use a piston connecting rod crankshaft to convert reciprocating linear motion into rotary motion, does not need to use a triangular rotor to rotate eccentrically in an elliptical cylinder, and does not need to use the compression of a compressor and the conversion of a turbine. Therefore, compared with the existing engine devices, it has the advantages of simple structure, low cost, stable operation of the whole machine, low vibration level, large compression ratio, and high energy conversion rate.

[0082] Example 1

[0083] As Figure 1 shown, the fuel tank 1 is installed on the housing 15, the governor 2 is installed on the main rotating shaft 20, the main rotating shaft 20 is installed on the housing 15 through a bushing 139 with an oil hole, and the oil supply pump 4 is installed on the housing 15 through a reinforcing rib 3 and is engaged with the main rotating shaft 20. Four push-air burners 5 with the same structural shape, specifications, and dimensions are respectively installed on the first working cylinder 6, the second working cylinder 7, the third working cylinder 12, and the fourth working cylinder 13. The gas distributor 10 is installed on the compression cylinder 9, the water tank 14 is installed on the housing 15, and all cylinders are serially installed on the main rotating shaft 20 through the bushings 139 at the left and right end covers of the composite cylinder. The first working cylinder 6 and the fourth working cylinder 13, the second working cylinder 7 and the third working cylinder 12, and the left auxiliary cylinder 8 and the right auxiliary cylinder 11 are each installed symmetrically on the left and right sides centered on the compression cylinder 9. The four working cylinders, one compression cylinder, and two auxiliary cylinders are all fixed to the housing 15 through reinforcing ribs. The flat-sector rotary plugs 21 are respectively installed inside the first working cylinder 6, the second working cylinder 7, the left auxiliary cylinder 8, the compression cylinder 9, the right auxiliary cylinder 11, the third working cylinder 12, and the fourth working cylinder 13. All the flat-sector rotary plugs 21 are installed on the main rotating shaft 20 through flat keys. The oil radiator 16, the water pump 22, the starter 23, and the battery 17 are all installed on the housing 15. The oil pump 19 is installed on the housing 15 through a reinforcing rib and is engaged with the main rotating shaft 20. The flywheel 18 is installed on the main rotating shaft 20 through a flat key and a nut. The pulley 24 is installed on the flywheel 18, and the oil pan 141 is installed at the bottom of the housing 15. Each of the above-mentioned cylinders, including the working cylinders, the compression cylinder, and the auxiliary cylinders, which are of three different functional types, has different specifications and dimensions, but the technical structures and shapes are the same. Among them, the four working cylinders have the same structural shape, specifications, and dimensions, and the two auxiliary cylinders have the same structural shape, specifications, and dimensions.

[0084] Refer to Figure 2 Figure 3, at both end face parts of the composite cylinder 25 of the first working cylinder 6, the left end cover and the right end cover 37 are installed. The shapes, structures, and dimensions of the two are the same. The flat plate sector rotary plug 21 installed in the composite cylinder 25 is installed on the main rotating shaft 20 through a flat key. The two side faces and the far-stop push arc surface of the flat plate sector rotary plug 21 of the composite cylinder 25 are respectively in close fit with the left end cover and the right end cover 37 installed in the composite cylinder 25 and the inner wall curved surface of the composite cylinder 25, and can rotate flexibly counterclockwise. The cylinder water inlet 26, the cylinder water outlet 27, and the cylinder cooling water cavity 30 are used to connect the cooling water channel to play a role in cooling. The baffle plate 28 is installed in the composite cylinder 25 and is in close fit with and can slide on the outer edge surface of the flat plate sector rotary plug 21. These technical features of the above-mentioned first working cylinder 6 are the same as the technical features of each flat plate sector rotary plug and composite cylinder in the second working cylinder 7, the third working cylinder 12, the fourth working cylinder 13, the left auxiliary cylinder 8, the compression cylinder 9, and the right auxiliary cylinder 11 of the present invention.

[0085] Refer to Figure 4 Figure 5 , the composite cylinder 25 is provided with a cylinder air inlet 29, a cylinder cooling water cavity 30 for connecting the cooling water channel, a circular ring water sealing plate platform 31, a circular ring platform 32, a left platform 33, a right platform 34, a cylinder air outlet 35, and a baffle plate slot hole 36. The baffle plate slot hole 36 is used to install the baffle plate 28, and its cylinder air outlet 35 is used to discharge waste gas. Figure 5 is Figure 4 The schematic diagram in the left view direction of each technical element feature set on the composite cylinder 25 of the first working cylinder shown. These technical features of the composite cylinder 25 of the above-mentioned first working cylinder are the same as the technical features of each composite cylinder of the second working cylinder 7, the third working cylinder 12, the fourth working cylinder 13, the left auxiliary cylinder 8, the compression cylinder 9, and the right auxiliary cylinder 11 of the present invention.

[0086] Refer to Figure 6 , Figure 7 , the right end cover 37 of the composite cylinder 25 of the first working cylinder 6 is provided with an end cover cooling water cavity 38, an end cover cooling water inlet pipe port 39, an end cover cooling water outlet pipe port 40 for cooling, and a shaft sleeve 139 for passing through the main rotating shaft. These technical features of the left end cover and the right end cover 37 of the composite cylinder 25 of the above-mentioned first working cylinder 6 are the same as the technical features of the left end cover and the right end cover of each composite cylinder of the second working cylinder 7, the third working cylinder 12, the fourth working cylinder 13, the left auxiliary cylinder 8, the compression cylinder 9, and the right auxiliary cylinder 11 of the present invention.

[0087] Refer to Figure 8 , Figure 9 , Figure 10 , Figure 11, the water sealing plate 41 is pressed on the left end cover or the right end cover 37 by screws to seal the cooling water cavity 38 of the end cover. After sealing, the left end cover or the right end cover 37 is fixedly installed on the left platform 33 and the right platform 34 provided on the composite cylinder 25 by screws. The circular water sealing plate 42 is fixedly installed on the circular water sealing plate platform 31 provided on the composite cylinder 25 by screws to seal the cooling water cavity 30 of the cylinder. The circular platform 32 is used to enhance the stress intensity of the composite cylinder 25. The shapes and specifications of the right water sealing plate and the left water sealing plate are the same. The technical features of the first working cylinder 6 are the same as those of the respective composite cylinders of the second working cylinder 7, the third working cylinder 12, the fourth working cylinder 13, the left auxiliary cylinder 8, the compression cylinder 9, and the right auxiliary cylinder 11 of the present invention.

[0088] Refer to Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 . Although the specifications of the flat sector-shaped rotary plugs 21 installed in each cylinder of all the cylinders described above are not exactly the same, their structural shapes are the same. The flat sector-shaped rotary plug 21 can rotate flexibly when installed in the composite cylinder of the corresponding cylinder. The flat sector-shaped rotary plug 21 is provided with a shaft hole 48, a keyway 45, an oil hole 46 for the far-stop push arc surface, and an oil hole 47 for the side end face. The keyway 45 is used to fix the position of the flat sector-shaped rotary plug 21 on the main rotating shaft 20. The oil hole 46 for the far-stop push arc surface and the oil hole 47 for the side face are both communicated with the radial oil hole on the main rotating shaft 20 to ensure that the flat sector-shaped rotary plug 21 can be lubricated with oil during operation.

[0089] Two rows of sealing plates are installed on both sides of the flat sector-shaped rotary plug 21. Each row of sealing plates is composed of a left sealing plate 44 and a right sealing plate 43. The outer end of the left sealing plate 44 is provided with a left notch 53, and the outer end of the right sealing plate 43 is provided with a right notch 54. When the flat sector-shaped rotary plug 21 is installed in the working cylinder, the left notch 53 and the right notch 54 are fitted together. Each sealing plate is installed in a groove. The groove is provided with micro oil holes to facilitate the lubrication of the sealing plate with oil. Springs are also installed in the groove. After the flat sector-shaped rotary plug 21 is installed in the working cylinder, the two rows of sealing plates and the sealing sleeves on both sides are tightly pressed on the surface of the contacted workpiece to ensure good sealing performance of the flat sector-shaped rotary plug 21 when installed in the working cylinder.

[0090] The profile of the flat-sector rotary plug 21 is in a fan-shaped structure. In the clockwise direction, from point M 49 to point N 50 is the lifting arc surface section M-N of the profile of the flat-sector rotary plug 21, from point N 50 to point R 51 is the far-stop pushing arc surface section N-R of the profile of the flat-sector rotary plug 21, from point R 51 to point Y 52 is the playback arc surface section R-Y of the profile of the flat-sector rotary plug 21, and from point Y 52 to point M 49 is the near-stop pushing arc surface section Y-M of the profile of the flat-sector rotary plug 21. The arc surface curvature radius of the far-stop pushing arc surface section N-R is equal to the curvature radius of the inner cavity circular hole surface of the composite cylinder. The length of the far-stop pushing arc surface section N-R of the flat-sector rotary plug 21 is set to be four to six times the caliber width of the cylinder air inlet 29 on the composite cylinder 25 of the working cylinder. With this technical feature, it is ensured that during the process of the flat-sector rotary plug 21 passing through the air inlet 29 of the composite cylinder each time, its far-stop pushing arc surface section N-R can perform a short-term dynamic sealing function on the air inlet 29 of the composite cylinder, so as to facilitate the compressed air introduced into the combustion chamber (86) not to leak or decompress in a short time and fully mix and burn with the fuel.

[0091] When the flat-sector rotary plug 21 rotates inside the composite cylinder and touches and pushes against the grid plate 28 during the encounter, it is the lifting arc surface section M-N of the flat-sector rotary plug 21 that pushes the grid plate 28 to the upper part of the inner cavity curved surface of the composite cylinder, thereby opening the rotation path of the flat-sector rotary plug 21. After the flat-sector rotary plug 21 passes through, the grid plate 28 falls back under the spring pressure. These technical features of the flat-sector rotary plug 21 in the first working cylinder 6 are the same as those of the flat-sector rotary plugs in the composite cylinders of the second working cylinder 7, the third working cylinder 12, the fourth working cylinder 13, the left auxiliary cylinder 8, the compression cylinder 9, and the right auxiliary cylinder 11 of the present invention.

[0092] Refer to Figure 18 Figure 19 , the main rotating shaft 20 is provided with a central axis oil passage 55, and a plurality of radial oil holes 56 are also provided on the outer diameter of the main rotating shaft 20. The central axis oil passage (55) of the main rotating shaft (20) is connected to the radial oil holes 56, the oil holes of the housing bushing (139), and the oil holes of each flat-sector rotary plug.

[0093] Refer to Figure 20, the far-stop push arc surface 57 of the flat-sector rotary plug in the first working cylinder 6 installed on the main rotating shaft 20 faces upward, and the centrifugal force F158 generated during its rotational movement is upward. The far-stop push arc surface 59 of the flat-sector rotary plug in the second working cylinder 7 faces downward, and the centrifugal force F260 generated during its rotational movement is downward. The far-stop push arc surface 61 of the flat-sector rotary plug in the third working cylinder 12 faces downward, and the centrifugal force F362 generated during its rotational movement is downward. The far push arc surface 63 of the flat-sector rotary plug in the fourth working cylinder 13 faces upward, and the centrifugal force F464 generated during its rotational movement is upward. The centrifugal forces generated by the flat-sector rotary plugs in these four working cylinders during rotational movement generally cancel each other out. This layout can reduce the vibration intensity of the engine.

[0094] Refer to Figure 21 , the far-stop push arc surface 65 of the rotary plug in the compression cylinder 9 faces upward, and the centrifugal force F566 generated during its rotational movement is upward. The far-stop push arc surface 67 of the rotary plug in the left auxiliary cylinder 8 faces downward, and the centrifugal force F668 generated during its rotational movement is downward. The far-stop push arc surface 69 of the rotary plug in the right auxiliary cylinder 11 faces downward, and the centrifugal force F770 generated during its rotational movement is downward. The centrifugal force F668 and the centrifugal force F770 are equal in magnitude, and the vector sum of the two forces is equal in magnitude and opposite in direction to the centrifugal force F566 and cancels each other out. This layout can reduce the vibration intensity of the engine.

[0095] Refer to Figure 22, the air-pushing burner 5 is installed on the composite cylinder 25 of the working cylinder. A swingable left rocker arm 73 and a right rocker arm 74 are installed on the support column 94 provided on the air-pushing burner 5. The left ejector rod 71 and the right ejector rod 72 pass through the outer wall of the air-pushing burner and are respectively installed on the corresponding cams and rocker arms. The left rocker arm 73 is pushed by the left timing cam 93 and the left ejector rod 71 and has a thrusting effect on the left valve 75 and the right valve 76; the right rocker arm 74 is pushed by the right timing cam 92 and the right ejector rod 72 and has a thrusting effect on the push valve 77. The structural shape of the left valve 75 is the same as that of the right valve 76. The rod length of the right valve 76 is slightly shorter than that of the left valve 75 by 4 mm, so that the strokes of the right valve 76 and the left valve 75 pushed by the left rocker arm 73 are equal. After the right rocker arm 74 passes through the rectangular frame holes 96 on both the right valve 76 and the left valve 75, it can ensure that there is no contact among the right valve 76, the left valve 75, and the right rocker arm 74 during operation. The right timing cam 92 and the left timing cam 93 are both installed on the main rotating shaft 20 with flat keys. The oil inlet 78 of the air-pushing burner, the oil outlet 140 of the air-pushing burner are connected to the oil pipe. The air vent 79 of the air-pushing burner not only has the function of discharging oil but also can reduce the air resistance and negative pressure behind the pushing surface when the push valve 77 is working. The air storage chamber 82 is provided with an air storage chamber air inlet 81, an air storage chamber air outlet 83, and an air storage chamber one-way valve 80 to prevent the high-pressure gas in the air storage chamber 82 from flowing back through the air storage chamber air inlet 81. The combustion chamber 86 is provided with a combustion chamber air inlet 84, a combustion chamber air outlet 89, an injector 90, and a spark plug 91. The water inlet 85 of the air-pushing burner, the water outlet 87 of the air-pushing burner, and the water channel 88 of the air-pushing burner are used to connect to the cooling water channel to cool down the combustion chamber 86. The combustion chamber air outlet 89 is communicated with the air inlet 29 on the corresponding composite cylinder 25 of the working cylinder. These technical features of the air-pushing burner 5 of the first working cylinder 6 are the same as the technical features of each air-pushing burner on the second working cylinder 7, the third working cylinder 12, and the fourth working cylinder 13 of the present invention.

[0096] Refer to Figure 23, the grid plate base 95 is installed on the working cylinder 6, and the grid plate 28 is installed inside the grid plate base 95. When the far stop push arc surface between the N point 50 and the R point 51 of the flat fan-shaped rotary plug 21 is just at the corresponding position closing the air inlet 29, compressed gas starts to be input into the combustion chamber 86. After this working stroke ends, fuel is injected to form a combustible mixture. When the R point 50 rotates counterclockwise just past the air inlet 29, the combustible mixture in the combustion chamber 86 is ignited by the electric spark of the spark plug 91 to generate high-temperature and high-pressure gas. The high-temperature and high-pressure gas in the combustion chamber 86 enters the composite cylinder 25 of the working cylinder from the exhaust port 89 and the cylinder air inlet 29, pushing the flat fan-shaped rotary plug 21 to rotate and do work. The above structural and technical features of the grid plate base 95, the grid plate 28, and the flat fan-shaped rotary plug 21 of the first working cylinder 6 are the same as the structural and working technical features of the grid plate base, the grid plate, and the flat fan-shaped rotary plug in the second working cylinder 7, the third working cylinder 12, and the fourth working cylinder 13 of the present invention.

[0097] Refer to Figure 24 , Figure 24 is the specific structural shape of the left rocker arm 73 of the air-pushing burner 5 in specific applications.

[0098] Refer to Figure 25 , Figure 25 is the specific structural shape of the right rocker arm 74 of the air-pushing burner 5 in specific applications.

[0099] Refer to Figure 26 Figure 27 , Figure 26 Figure 27 Refer to

[0100] Refer to Figure 28 Figure 29 Figure 30 , the push valve 77 of the air-pushing burner 5 is composed of a small-diameter disc 131 installed at the upper end of a cylinder 130 and a large-diameter disc 132 installed at the lower end. Threads are provided at both ends of the cylinder, screw holes are provided at the centers of the two discs, and the cylinder and the two discs are tightened together by screws. A central oil hole 97 is provided in the cylinder, and three sealing spring rings 98 are provided on the large-diameter disc 132. The three sealing spring rings 98 are installed in a ring groove, and radial small holes are provided in the ring groove and communicate with the central oil hole 97. Figure 29 is Figure 28Partial structural schematic diagram of the valve push rod 77 in the D direction. The central oil passage 97 has an opening 137 on the outer diameter surface of the cylinder, which is used to communicate with the oil chamber 99 of the gas-pushing burner. Figure 30 is Figure 28 The structural schematic diagram of the valve push rod in the R direction as shown.

[0101] Refer to Figure 31 , the central oil passage 97 of the valve push rod 77 is connected to the oil chamber 99 on the gas-pushing burner 5, the oil inlet pipe 78 and the oil outlet pipe 140. The three sealing spring rings 98 can be lubricated by the oil output by the oil pump. The vent port 79 can reduce the air resistance and negative pressure behind the pushing surface when the valve push rod 77 is working, and the vent port 79 also has the function of discharging oil.

[0102] Refer to Figure 32 Figure 33 Figure 34 Figure 35 , the base water inlet 100, the base cooling water passage 102 and the base water outlet 104 provided on the baffle base 95 are connected to each other, and can be connected to the cooling water circulation path to cool the baffle base 95 during operation. The oil inlet pipe 101 and the oil outlet pipe 103 can be connected to the lubricating oil circulation path to provide lubricating oil for the baffle 28 during operation and reduce the friction force when the baffle 28 moves. The structures, shapes and specifications of the front seal door 106 and the rear seal door 105 are the same. The front seal door 106 and the rear seal door 105 are always tightly pressed on the front and rear surfaces of the baffle 28 to ensure the sealing performance of the baffle 28 on the front and rear surfaces during operation.

[0103] A spring is installed inside the baffle base 95. After the baffle 28 is installed inside the baffle base 95, the baffle 28 is under the pressure of the spring and tightly presses on the flat sector rotary plug inside the composite cylinder. The baffle 28 is fixedly composed of two parts, a round handle 133 and a long plate 134. On both sides of the long plate 134, there are a left sealing plate 44 and a right sealing plate 43. In the middle of the long plate 134, there is a baffle oil hole 136. The bottom end of the long plate 134 is set in the shape of an inclined arc surface 135. The inclined arc surface 135 is used to ensure that when the baffle 28 is pushed by the lifting arc surface of the flat sector rotary plug 21, it can move up and down flexibly, and make the baffle 28 fit tightly with the flat sector rotary plug 21 without air leakage. The left and right sealing plates on both sides of the baffle 28 have the same shape as the sealing plates on the flat sector rotary plug. The oil inside the baffle base 95 can enter the oil hole of the baffle 28. The front sealing door 106, the rear sealing door 105 inside the baffle base 95 and the left and right sealing plates of the baffle 28 enable the baffle installed inside the baffle base to fit tightly with the inner wall of the baffle base and slide up and down, effectively preventing the high-pressure gas inside the composite cylinder from leaking from the baffle slot holes. There is relative flexible movement and good sealing performance among the baffle base, the baffle, the composite cylinder and the flat sector rotary plug. The above structures and technical features of the baffle base 95 and the baffle of the first working cylinder 6 are the same as the structural and technical features of the baffle bases and baffles of the second working cylinder 7, the third working cylinder 12, the fourth working cylinder 13, the left auxiliary cylinder 8, the compression cylinder 9 and the right auxiliary cylinder 11 of the present invention.

[0104] Refer to Figure 36 Figure 37 Figure 38 , the baffle base 95 is installed on the upper part of the compression cylinder 9, and the gas distributor 10 is installed on the upper part at the air outlet 35 of the compression cylinder 9. The gas distributor 10 is provided with a distributor "Y" - shaped outlet pipe 107, a distributor air inlet 138, a distributor pressure regulating valve 108 and a distributor check valve 109. There are a total of two "Y" - shaped outlet pipes 107, left and right, on the gas distributor 10, and each "Y" - shaped outlet pipe 107 has two single ports 142. The pressure regulating valve 108 can adjust the pressure of the compressed gas inside the gas distributor according to different technical requirements. The distributor check valve 109 can prevent the compressed gas inside the distributor from flowing back. When the flat sector rotary plug inside the compression cylinder 9 rotates counterclockwise, the arc surface of the flat sector rotary plug where the M point 49 and the N point 50 are located always compresses air into the air distribution chamber 10 through the cylinder air outlet 35 and the distributor air inlet 138, and then through the distributor "Y" - shaped outlet pipe 107, the compressed high - pressure air is input into the air storage chambers of each thruster. The arc surface of the flat sector rotary plug where the R point 51 and the Y point 52 are located always sucks air from the compression cylinder air inlet 29 into the compression cylinder 9.

[0105] Refer toFigure 39 , the exhaust ports 35 of both the first working cylinder 6 and the second working cylinder 7, and the intake port 29 of the left auxiliary cylinder 8 are all connected to the converging air pipe 110. During operation, when the flat sector plugs in the first working cylinder 6 and the second working cylinder 7 rotate synchronously past the composite cylinder exhaust ports 35 of the cylinders respectively, the high-temperature and high-pressure gas after cooling and pressure reduction passes through the cylinder exhaust port 35 and enters the left auxiliary cylinder through the intake port 29 of the left auxiliary cylinder 8, further exerting a thrust on the flat sector plug 21 in the left auxiliary cylinder 8. During this process, the temperature and pressure of the high-temperature and high-pressure gas have gradually dropped to waste gas, and finally enter the collecting and filtering chimney from the exhaust port 35 of the left auxiliary cylinder 8 and are discharged into the atmosphere after purification and filtration. The above-mentioned linkage working technical features of the first working cylinder 6, the second working cylinder 7, and the left auxiliary cylinder 8 during operation are the same as the linkage working technical features of the third working cylinder 12, the fourth working cylinder 13, and the right auxiliary cylinder 11 during operation.

[0106] Refer to Figure 40 Figure 41, during the rotation of the flat sector rotary plug 21 within the composite cylinder 25, the flat sector rotary plug 21 and the baffle plate 28 always divide the inner cavity of the composite cylinder 25 into two different types of conditions: one type of condition is that the cylinder air inlet 29 of the composite cylinder is not connected to the cylinder air outlet 35, and the other type of condition is that the cylinder air inlet 29 of the composite cylinder is interconnected with the cylinder air outlet 35. These two conditions occur in a cycle of waxing and waning of yin and yang, enabling the intake, compression working stroke of the flat sector rotary plug 21 in the compression cylinder of the present invention and the working stroke of doing work and exhausting air of the flat sector rotary plug 21 in the working cylinder to proceed synchronously and continuously. Along the rotation direction of the flat sector rotary plug 21: (1) When the baffle plate 28 in the composite cylinder of the compression cylinder 9 and the flat sector rotary plug 21 cause the cylinder air inlet 29 of the composite cylinder to be not connected to the cylinder air outlet 35, while the flat sector rotary plug 21 sucks in air from the cylinder air inlet 29 of the compression cylinder 9, it also presses gas into the gas distributor 10 from the cylinder air outlet 35 and the distributor air inlet 138. And when the cylinder air inlet 29 of the composite cylinder of the compression cylinder 9 is interconnected with the cylinder air outlet 35, the intake and compression working stroke of the compression cylinder 9 by the flat sector rotary plug 21 ends. (2) When the baffle plate 28 in the composite cylinder of the working cylinder and the flat sector rotary plug 21 cause the cylinder air inlet 29 to be not connected to the cylinder air outlet 35, the high-pressure gas from the combustion chamber 86 rushes into the cavity between the flat sector rotary plug 21 and the baffle plate 28 in the composite cylinder 25 of the working cylinder. The flat sector rotary plug 21 is pushed by the high-pressure gas to rotate and do work. At the same time, the flat sector rotary plug 21 also sweeps out the waste gas along the way from the cylinder air outlet 35. And when the cylinder air inlet is interconnected with the cylinder air outlet, the high-pressure gas inside the composite cylinder of the working cylinder is discharged from the cylinder air outlet 35, and the working stroke of doing work and sweeping out waste gas of the flat sector rotary plug 21 in the working cylinder ends. (3) The working stroke of the baffle plate and the flat sector rotary plug in the composite cylinder of the two auxiliary cylinders is carried out successively with the working stroke of the baffle plate and the sector rotary plug in the composite cylinder of the above-mentioned working cylinder. When the rotation and exhaust stroke of the flat sector rotary plug 21 in the composite cylinder of the working cylinder end, the cylinder air inlet 29 in the auxiliary cylinder accesses the gas discharged from the cylinder air outlet 35, continuously pushing the flat sector rotary plug 21 in the auxiliary cylinder to rotate and do work. And when the flat sector rotary plug 21 in the composite cylinder of the working cylinder starts to rotate and do work again, the rotation and working stroke of the flat sector rotary plug 21 in the auxiliary cylinder ends, and only the exhaust stroke follows successively.

[0107] Refer to Figure 42, the oil collecting and filtering chimney 116 is installed at the bottom of the engine housing 15. The structure of the oil collecting and filtering chimney 116 consists of a chimney right air inlet 111, a chimney left air inlet 118, a first filtering chamber 112, a second filtering chamber 113, a third filtering chamber 114, a fourth filtering chamber 125, a right sediment collecting cup 115, a left sediment collecting cup 119, a middle sediment collecting cup 121, a filtering cup 123, an oil return pipe 124, a slag cleaning bolt 117, a left self-opening valve 120, a right self-opening valve 122, and a smoke exhaust port 126. During operation, the waste gas discharged from the air outlet of the right auxiliary cylinder 11 enters the chimney right air inlet 111 of the oil collecting and filtering chimney 116; the waste gas discharged from the air outlet of the left auxiliary cylinder 8 enters the chimney left air inlet 118 of the oil collecting and filtering chimney 116. The two streams of waste gas converge into one in the first filtering chamber 112, then turn and flow into the second filtering chamber 113, the third filtering chamber 114, and the fourth filtering chamber 125, and then are discharged into the atmosphere. During this process, the residual oil droplets and fine particles in the waste gas bend and collide with the chamber wall along with the airflow inside the filtering chamber wall, so as to precipitate and accumulate in the three cups of the right sediment collecting cup 115, the left sediment collecting cup 119, and the middle sediment collecting cup 121. The left self-opening valve 120 and the right self-opening valve 122 have the same structure, and both have the function of closing when subjected to the pressure of the flowing waste gas and automatically opening by relying on the spring force when the engine stops and there is no pressure of the flowing waste gas. The left self-opening valve 120 and the right self-opening valve 122 are closed during engine operation and open when the engine stops. This enables the residual oil droplets precipitated and accumulated in the three cups of the right sediment collecting cup 115, the left sediment collecting cup 119, and the middle sediment collecting cup 121 to flow towards the filtering cup 123 when the engine stops. The residual oil filtered by the filtering cup 123 flows back into the oil pan through the oil return pipe 124. Since the left self-opening valve and the right self-opening valve are in the closed state during engine operation, the waste gas flowing through the oil collecting and filtering chimney 116 will not enter the oil pan during engine operation. The particulate slag in the three sediment collecting cups is periodically removed by unscrewing the slag cleaning bolt 117.

[0108] According to the technical features of all the above components, when the cylindrical main rotating shaft series integrated engine device of the present invention works, first, the starter 23 is powered on and started. The starter 23 starts to drive the main rotating shaft 20 and the energy storage flywheel 18 to rotate. The flat sector rotary plugs in the four working cylinders, the flat sector rotary plugs in the compression cylinder, and the flat sector rotary plugs in the two auxiliary cylinders rotate synchronously on the same main rotating shaft 20. The flat sector rotary plug 21 in the compression cylinder 9 sucks air into the compression cylinder 9 through the air inlet 29 on one side, and at the same time compresses the air into the gas distributor 10 on the other side. The gas distributor 10 inputs the compressed air into the air storage chambers 82 of the air-pushing burners on each working cylinder through the "Y"-shaped outlet pipe 107 of the distributor. At this time, the air-pushing valves 77, the left valves 75, and the right valves 76 of each air-pushing burner do not move, and the air passage between the exhaust port 83 of the air storage chamber 82 and the air inlet 84 of the combustion chamber 86 is closed. The closing effect of the right valve 76 on the air passage connected to the exhaust port 83 of the air storage chamber 82 prevents the compressed air in the air storage chamber 82 from prematurely flowing into the air passage connected to the air inlet 84 of the combustion chamber 86, thus preventing air leakage by opening the left valve 75. Further, after the working stroke of inputting compressed air into the air storage chamber 82 ends, the air inlet 81 of the air storage chamber 82 is closed by the check valve 80, preventing the compressed air in the air storage chamber 82 from flowing back to the distributor 10. Further, then, the left push rods 71 and the right push rods 72 and the left rocker arms 73 and the right rocker arms 74 outside each working cylinder are pushed by their respective timing cams to push the air-pushing valves 77, the left valves 75, and the right valves 76 on the air-pushing burner, open the air outlet 83 of the air storage chamber 82, and open the air inlet 84 of the combustion chamber 86, pushing the compressed air into the combustion chamber 86. At the same time, the arc surface N-R section from point N to point R of the far stop stroke arc surface of the flat sector rotary plug in each working cylinder just closes the composite cylinder air inlet 29 of the cylinder and the air outlet 89 of the combustion chamber 86, preventing the compressed air in the combustion chamber 86 from leaking and de-pressurizing in a short period of time, which is beneficial for mixing and burning with fuel. Further, when the left valve 75 and the right valve 76 reset and close the upper air inlet passage 84 of the combustion chamber 86, the air-pushing valve 77 resets, the fuel injector 90 injects fuel into the combustion chamber 86 to form a combustible mixture, the spark plug 91 emits a spark, and the fuel burns to generate high-temperature and high-pressure gas. At this time, the far stop push arc surface point R of the flat sector rotary plug in each working cylinder just rotates away from the composite cylinder air inlet 29 of the cylinder, opening the composite cylinder air inlet 29 of the cylinder and the air outlet 89 of the combustion chamber 86. The high-temperature and high-pressure gas simultaneously rushes towards the flat sector rotary plug and the baffle. Since the high-temperature and high-pressure gas cannot push the baffle and the baffle has good sealing performance, the high-temperature and high-pressure gas in each working cylinder pushes the flat sector rotary plug therein to drive the main rotating shaft 20 and the flywheel 18 to rotate and do work. As the flat sector rotary plug, the main rotating shaft, and the flywheel rotate, the temperature and pressure of the high-temperature and high-pressure gas also gradually decrease.After the flat sector rotary plugs in each working cylinder have each rotated past the composite cylinder air outlet 35 of the cylinder, the high-temperature and high-pressure gas that has been cooled and depressurized and discharged from the composite cylinder air outlets of the first working cylinder 6 and the second working cylinder 7 enters the left auxiliary cylinder 8 from the air inlet 29 of the left auxiliary cylinder 8, further exerting a thrust on the flat sector rotary plug 21 in the left auxiliary cylinder 8; the high-temperature and high-pressure gas that has been cooled and depressurized and discharged from the composite cylinder air outlets of the third working cylinder 12 and the fourth working cylinder 13 enters the right auxiliary cylinder 11 to further exert a thrust on the flat sector rotary plug 21 in the right auxiliary cylinder 11. Finally, the gas that has been cooled and depressurized and discharged from the left auxiliary cylinder 8 and the right auxiliary cylinder 11 has dropped to waste gas. The waste gas discharged from the air outlet of the right auxiliary cylinder 11 enters the right air inlet 111 of the chimney of the collecting and filtering chimney 116; the waste gas discharged from the air outlet of the left auxiliary cylinder 8 enters the left air inlet 118 of the chimney of the collecting and filtering chimney 116. The two streams of waste gas converge into one in the first filtering chamber 112 of the collecting and filtering chimney 116, and then continuously pass through to the second filtering chamber 113, the third filtering chamber 114, and the fourth filtering chamber 125, and then are discharged into the atmosphere. Among them, the residual oil droplets in the waste gas flow back into the oil pan through the oil return pipe 124, and the particulate slag in the waste gas precipitates and accumulates in the three sedimentation cups, namely the right sedimentation cup 115, the left sedimentation cup 119, and the middle sedimentation cup 121, and is periodically removed by unscrewing the slag cleaning bolt 117.

These technologies are now publicly available and mature. In the present invention, the working cylinders can also be two, six, eight, or ten, which are technical solutions that can be easily conceived without much mental effort. Therefore, the specific implementation manners of the present invention do not need to be listed one by one. Specific Embodiment 2

[0112] Refer to Figure 43, in the low-power models of the engine device of the present invention, in order to be applicable to the technical characteristics of the low-power models, such as simple structure, low power, light body weight, and low cost, the left auxiliary cylinder 8 and the flat-sector rotary plug therein of the engine device of the present invention are replaced by the left counterweight iron block 143, and the right auxiliary cylinder 11 and the flat-sector rotary plug therein are replaced by the right counterweight iron block 144. The left counterweight iron block 143 and the right counterweight iron block 144 are both installed on the main rotating shaft with flat keys, and their respective phases are the same as those of the flat-sector rotary plugs in the auxiliary cylinders they replace. During operation, the centrifugal forces generated by the rotation of the left counterweight iron block 143 and the right counterweight iron block 144 cancel out the centrifugal forces generated by the rotation of the flat-sector rotary plugs in the compression cylinders. The gases discharged from the first working cylinder 6, the second working cylinder 7, the third working cylinder 12, and the fourth working cylinder 13 directly enter the collecting and filtering chimney 116 and are discharged after filtration. Through the above technical measures, the structure of the engine of the present invention is made simpler, the body weight is reduced, and the cost is lowered, ensuring that the engine device of the present invention can be applicable to the technical characteristics of low-power models.

The front sealing door (106) and the rear sealing door (105) have the same shape, specifications, and dimensions. The front sealing door (106) and the rear sealing door (105) always tightly press on the front and rear plate surfaces of the baffle (28) to ensure the sealing performance of the baffle (28) on the front and rear plate surfaces during operation; The described baffle (28) is installed inside the baffle base (95). A spring is installed inside the baffle base (95). The baffle (28) is under the pressure of the spring and tightly presses on the flat sector-shaped rotary plug (21) inside the composite cylinder.

The length of the far-stop push arc face section N-R of the flat sector rotary plug (21) is set to be four times the caliber width of the air inlet N (29) on the working cylinder composite cylinder. With this technical feature, it is ensured that during the process of the flat sector rotary plug (21) rotating past the air inlet (29) of the composite cylinder where it is located each time, its far-stop push arc face section N-R can perform a short-term dynamic sealing function on the air inlet (29) of the composite cylinder, so as to facilitate the compressed air introduced into the combustion chamber (86) not to leak or decompress in a short time and be fully mixed with fuel for combustion; The flat sector rotary plug (21) is provided with a shaft hole (48), a keyway (45), an oil hole (46) on the far-stop push arc face, and an oil hole (47) on the side end face. The keyway (45) is used to fix the position of the flat sector rotary plug (21) on the main rotating shaft (20). The oil hole (46) on the far-stop push arc face and the oil hole (47) on the side are both communicated with the radial oil hole on the main rotating shaft (20) to ensure that the flat sector rotary plug (21) can be lubricated with oil during operation; Two rows of sealing plates are installed on both sides of the flat sector rotary plug (21).

The two side surfaces and the far-stop push arc surface of the flat sector rotary plug are respectively in close fit and can rotate flexibly with the left end cover, the right end cover and the inner wall curved surface of the composite cylinder installed in the composite cylinder. When the flat sector rotary plug (21) rotates inside the composite cylinder (25), during the process of mutual contact and pushing when it meets the grid plate (28), it is the M-N section of the push-up arc surface of the flat sector rotary plug (21) that pushes the grid plate (28) to the upper part of the inner cavity curved surface of the composite cylinder (25), opening the rotation path of the flat sector rotary plug (21). After the flat sector rotary plug (21) passes through, the grid plate (28) falls back under the spring pressure; During the rotation of the flat-sector rotary plug (21) within the composite cylinder (25), the flat-sector rotary plug (21) and the grid plate (28) always divide the inner cavity of the composite cylinder (25) into two different types of conditions: One type of condition is that the cylinder air inlet (29) of the composite cylinder (25) is not connected to the cylinder air outlet (35), and the other type of condition is that the cylinder air inlet (29) of the composite cylinder (25) is interconnected with the cylinder air outlet (35). These two conditions occur in a cycle of waxing and waning of yin and yang, enabling the intake, compression working stroke of the flat-sector rotary plug (21) in the compression cylinder of the present invention and the working stroke of the flat-sector rotary plug (21) in the working cylinder for work and exhaust to proceed synchronously and continuously. Along the rotation direction of the flat-sector rotary plug (21): (1) When the grid plate (28) in the composite cylinder (25) of the compression cylinder (9) and the sector rotary plug (21) cause the cylinder air inlet (29) to be not connected to the cylinder air outlet (35), while the compression cylinder (9) intakes air from the cylinder air inlet (29), it also presses air from the cylinder air outlet (35) into the gas distributor (10). And when the cylinder air inlet (29) and the cylinder air outlet (35) of the compression cylinder (9) are interconnected, the intake and compression working stroke of the flat-sector rotary plug (21) in the compression cylinder (9) ends. (2) When the grid plate (28) in the composite cylinder (25) of the working cylinder and the sector rotary plug (21) cause the cylinder air inlet (29) and the cylinder air outlet (35) to be not connected, the high-pressure gas from the combustion chamber (86) rushes into the cavity between the flat-sector rotary plug (21) and the grid plate (28) through the cylinder air inlet (29) of the composite cylinder (25) of the working cylinder. The flat-sector rotary plug (21) is pushed by the high-pressure gas to rotate and do work. At the same time, the flat-sector rotary plug (21) also sweeps out the waste gas along the way from the cylinder air outlet (35). And when the cylinder air inlet (29) and the cylinder air outlet (35) are interconnected, the high-pressure gas inside the composite cylinder (25) of the working cylinder is discharged from the cylinder air outlet (35), and the working stroke of the flat-sector rotary plug (21) in the working cylinder for work and exhaust of waste gas ends. (3) The working strokes of the grid plate and the flat-sector rotary plug in the composite cylinders of the two auxiliary cylinders are carried out successively with the working strokes of the grid plate and the sector rotary plug in the composite cylinder of the above-mentioned working cylinder. When the rotation for work and exhaust stroke of the flat-sector rotary plug (21) in the composite cylinder of the working cylinder ends, the cylinder air inlet (29) in the auxiliary cylinder accesses the gas discharged from the cylinder air outlet (35), continuously pushing the flat-sector rotary plug (21) in the auxiliary cylinder to rotate and do work. And when the flat-sector rotary plug (21) in the composite cylinder of the working cylinder starts to rotate for work and exhaust stroke again, the rotation for work stroke of the flat-sector rotary plug (21) in the auxiliary cylinder ends, and only the exhaust stroke follows successively; The engine of the present invention only has a cylindrical main rotating shaft (20). The main rotating shaft (20) passes through the left end cover bushing and the right end cover bushing (139) in the composite cylinder of each cylinder including all working cylinders, auxiliary cylinders, and compression cylinders, and the shaft hole (48) of the flat sector rotary plug. Each flat sector rotary plug (21) installed in series in each cylinder on the main rotating shaft (20) is fixedly installed on the main rotating shaft (20) with a flat key. Each timing cam of each air-pushing burner (5) is fixedly installed on the main rotating shaft (20) with a flat key to provide thrust for timing the push rod and rocker arm outside the working cylinder. A flywheel (18) and a pulley (24) are also installed on the main rotating shaft (20). Finally, after the front end and the rear end of the main rotating shaft (20) pass through the housing bushing (139), they are installed on the housing (15) of the engine of the present invention. The housing bushing (139) has an oil hole communicating with the central axis oil passage (55) of the main rotating shaft (20). Thus, by using a cylindrical main rotating shaft (20), all the cylinders of the present invention and the accessories installed inside and outside the cylinders are installed in series as a whole; The main rotating shaft (20) is provided with a central axis oil passage (55) and radial oil holes (56) to communicate with the oil holes of each flat sector rotary plug; For the working cylinders, auxiliary cylinders, and compression cylinders installed in series on the main rotating shaft (20), the phase relationship between them in the apparent plane is: taking a compression cylinder (9) as the center, the specific conditions of the cylinders installed symmetrically on its left and right sides are, in order from left to right: the first working cylinder (6), the second working cylinder (7), the left auxiliary cylinder (8), the compression cylinder (9), the right auxiliary cylinder (11), the third working cylinder (12), and the fourth working cylinder (13); For each flat sector rotary plug (21) installed in series in each cylinder on the main rotating shaft (20), the phase relationship between them in the apparent plane is: the far-stop push arc surface part (57) of the flat sector rotary plug contour in the first working cylinder (6) is upward, the far-stop push arc surface part (59) of the flat sector rotary plug in the second working cylinder (7) is downward, the far-stop push arc surface part (67) of the flat sector rotary plug contour in the left auxiliary cylinder (8) is downward, the far-stop push arc surface part (65) of the flat sector rotary plug contour in the compression cylinder (9) is upward, the far-stop push arc surface part (69) of the flat sector rotary plug contour in the right auxiliary cylinder (11) is downward, the far-stop push arc surface part (61) of the flat sector rotary plug contour in the third working cylinder (12) is downward, and the far-stop push arc surface part (63) of the flat sector rotary plug contour in the fourth working cylinder (13) is upward. The technical feature of this layout can ensure that the centrifugal forces of the flat sector rotary plugs (21) in the four working cylinders cancel each other out during rotational motion; ensure that the rotational centrifugal force of the flat sector rotary plug in the compression cylinder (9) cancels out the centrifugal forces among the flat sector rotary plugs in the left auxiliary cylinder (8) and the right auxiliary cylinder (11) to reduce the engine vibration intensity; When the engine device of the present invention works, the flat sector rotary plugs in the four working cylinders, the flat sector rotary plug in the compression cylinder (9), and the flat sector rotary plugs in the two auxiliary cylinders rotate synchronously on the same main rotating shaft (20). The flat sector rotary plug (21) in the compression cylinder (9) sucks air into the compression cylinder (9) through the air inlet (29) on one side, and at the same time compresses the air into the gas distributor (10) on the other side. The gas distributor (10) inputs the compressed air into the air storage chambers (82) of the air-pushing burners on each working cylinder through the four single ports (142) of the two "Y"-shaped outlet pipes (107) on the left and right. At this time, the air-pushing valves (77), left valves (75), and right valves (76) of each air-pushing burner do not move, and the air passage between the air outlet (83) of the air storage chamber (82) and the air inlet (84) of the combustion chamber (86) is closed. The closing effect of the right valve (76) on the air passage connected to the air outlet (83) of the air storage chamber (82) prevents the compressed air in the air storage chamber (82) from prematurely entering the air passage connected to the air inlet (84) of the combustion chamber (86), thereby flushing open the left valve (75) and causing an air leakage effect. When the working stroke of inputting compressed air into the air storage chamber (82) ends, the air inlet (81) of the air storage chamber (82) is closed by the one-way valve (80), preventing the compressed air in the air storage chamber (82) from flowing back to the distributor (10). Further, then, the left push rods (71) and right push rods (72) and left rocker arms (73) and right rocker arms (74) outside each working cylinder are pushed by their respective timing cams to push the left valve (75), right valve (76), and air-pushing valve (77) on the air-pushing burner, open the air outlet (83) of the air storage chamber (82), and open the air inlet (84) of the combustion chamber (86), pushing the compressed air into the combustion chamber (86). At the same time, the arc surface N-R section from point N (50) to point R (51) of the far stop stroke arc surface of the flat sector rotary plug in each working cylinder just closes the composite cylinder air inlet (29) of the cylinder and the air outlet (89) of the combustion chamber (86). Further, when the left valve (75) and the right valve (76) reset and close the upper air inlet passage (84) of the combustion chamber (86), the air-pushing valve (77) resets. Further, then, the fuel injector (90) sprays fuel into the combustion chamber (86) to form a combustible mixture, the spark plug (91) emits a spark, and the fuel burns to generate high-temperature and high-pressure gas. At this time, the point R (point 50) of the far stop push arc surface of the flat sector rotary plug in each working cylinder just rotates away from the composite cylinder air inlet (29) of the cylinder, opening the composite cylinder air inlet (29) of the cylinder and the air outlet (89) of the combustion chamber (86). The high-temperature and high-pressure gas simultaneously rushes towards the flat sector rotary plug (21) and the baffle plate (28). Since the high-temperature and high-pressure gas cannot push the baffle plate (28), and the baffle plate (28) has good sealing performance,Therefore, the high-temperature and high-pressure gas in each working cylinder drives the flat-sector rotary plug (21) therein to drive the main rotating shaft (20) and the flywheel (18) to rotate and do work. As the flat-sector rotary plug (21), the main rotating shaft (20) and the flywheel (18) rotate, the temperature and pressure of the high-temperature and high-pressure gas also gradually decrease. When the flat-sector rotary plug (21) in each working cylinder has passed through the composite cylinder air outlet (35) of the cylinder respectively, further, the high-temperature and high-pressure gas after cooling and pressure reduction discharged from the composite cylinder air outlets (35) of the first working cylinder (6) and the second working cylinder (7) enters the left auxiliary cylinder (8) from the cylinder air inlet (29) of the left auxiliary cylinder (8), and further exerts a thrust on the flat-sector rotary plug (21) in the left auxiliary cylinder (8); the high-temperature and high-pressure gas after cooling and pressure reduction discharged from the composite cylinder air outlets (35) of the third working cylinder (12) and the fourth working cylinder (13) enters the right auxiliary cylinder (11) and further exerts a thrust on the flat-sector rotary plug (21) in the right auxiliary cylinder (11). Finally, the gas after cooling and pressure reduction discharged from the left auxiliary cylinder (8) and the right auxiliary cylinder (11) has dropped to waste gas. The waste gas discharged from the air outlet of the right auxiliary cylinder (11) enters the right air inlet (111) of the collecting and filtering chimney (116); the waste gas discharged from the air outlet of the left auxiliary cylinder (8) enters the left air inlet (118) of the collecting and filtering chimney (116). The two streams of waste gas converge into one in the first filtering chamber (112) of the collecting and filtering chimney (116), and continuously pass through the second filtering chamber (113), the third filtering chamber (114), the fourth filtering chamber (125), and the smoke exhaust port (126), and then are discharged into the atmosphere. Among them, the residual oil droplets in the waste gas flow back into the oil pan (141) through the oil return pipe (124), and the particulate slag in the waste gas precipitates and accumulates in the three sedimentation cups of the right sedimentation cup (115), the left sedimentation cup (119), and the middle sedimentation cup (121), and is removed regularly by unscrewing the slag cleaning bolt (117).

2. The cylindrical main rotating shaft series-integrated engine according to claim 1, characterized in that, The push valve (77) is composed of a small-diameter disc (131) installed at the upper end of a cylinder (130) and a large-diameter disc (132) installed at the lower end. Threads are provided at both ends of the cylinder, screw holes are provided at the centers of the two discs, and the cylinder and the two discs are tightened into one body by screws. The cylinder (130) is provided with a central oil passage (97). The large-diameter disc (132) is provided with three sealing spring rings (98). The three sealing spring rings (98) are installed in a ring groove. Radial small holes are provided in the ring groove and are connected to the central oil passage (97). A through port (137) is provided on the outer diameter surface of the cylinder and is connected to the central oil passage (97).

3. A cylindrical main rotating shaft series integrated engine according to claim 1, characterized in that, The oil collecting and smoke filtering cylinder (116) is provided with a right air inlet (111), a left air inlet (118), a first filtering chamber (112), a second filtering chamber (113), a third filtering chamber (114), a fourth filtering chamber (125), a right sediment collecting cup (115), a left sediment collecting cup (119), a middle sediment collecting cup (121), a filtering cup (123), an oil return pipe (124), a slag cleaning bolt (117), a left self-opening valve (120), a right self-opening valve (122), and a smoke exhaust port (126). When the engine is working, the waste gas discharged from the air outlet of the right auxiliary cylinder (11) enters the right air inlet (111) of the oil collecting and smoke filtering cylinder (116), and the waste gas discharged from the air outlet of the left auxiliary cylinder (8) enters the left air inlet (118) of the oil collecting and smoke filtering cylinder (116). The two waste gases converge into one in the first filtering chamber (112), and then turn and pass through the second filtering chamber (113), the third filtering chamber (114), and the fourth filtering chamber (125), and then are discharged into the atmosphere. During this process, the residual oil droplets and fine particles in the waste gas bend and collide with the chamber wall along with the airflow inside the filtering chamber wall, so as to precipitate and accumulate in the three cups of the right sediment collecting cup (115), the left sediment collecting cup (119), and the middle sediment collecting cup (121). The left self-opening valve (120) and the right self-opening valve (122) have the same structure and both have the function of closing when affected by the pressure of the flowing waste gas and automatically opening by relying on the spring force when the engine stops and there is no pressure of the flowing waste gas. The left self-opening valve (120) and the right self-opening valve (122) are closed when the engine is working and are open when the engine stops. This enables the residual oil droplets precipitated and accumulated in the three cups of the right sediment collecting cup (115), the left sediment collecting cup (119), and the middle sediment collecting cup (121) to flow to the filtering cup (123) when the engine stops. The residual oil filtered by the filtering cup (123) flows back into the oil pan through the oil return pipe (124). And when the engine is working, since the left self-opening valve and the right self-opening valve are in a closed state, the waste gas flowing through the oil collecting and smoke filtering cylinder (116) during engine operation will not enter the oil pan 141. The particulate slag in the three sediment collecting cups is removed regularly by unscrewing the slag cleaning bolt (117).

Both the left counterweight iron block (143) and the right counterweight iron block (144) are installed on the main rotating shaft (20) with flat keys, and their respective phases are the same as the phases of the flat-sector rotary plugs in the auxiliary cylinders they replace.
