Description

A type of integrated engine with a single cylindrical main shaft Technical fields:

[0001] This invention relates to an internal combustion engine of the internal combustion technology type, which generates high-temperature, high-pressure expanding gas by causing fuel and compressed air to explode and burn in a combustion chamber, and then converts the high-temperature, high-pressure expanding gas into mechanical power. Background technology:

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

[0003] The reciprocating piston engine works by burning fuel in a sealed cylinder to produce high-temperature, high-pressure expanding gas, which drives the piston in a reciprocating linear motion. The connecting rod and crankshaft convert this reciprocating linear motion into the rotational motion of a flywheel, thus achieving energy conversion and output. The disadvantages of the reciprocating piston engine are high vibration, low energy conversion rate, and fuel waste. The Wankel engine works by using a triangular rotor to divide the inner cavity of an elliptical cylinder into three independent combustion chambers. The triangular rotor rotates eccentrically within the elliptical cylinder, causing the volume of the three independent combustion chambers to continuously change, thereby achieving the four strokes of intake, compression, power, and exhaust. The disadvantages of the Wankel engine are low compression ratio, incomplete combustion, low energy conversion rate, and high fuel consumption. The working principle of a gas turbine is to draw in air through a compressor and compress it in stages. The compressed air enters the combustion chamber and mixes with the injected fuel to produce high-temperature and high-pressure gas. This high-temperature and high-pressure gas then enters the turbine to expand and do work. The disadvantages of gas turbines are that they have a complex structure, low energy conversion rate, high cost, and high noise.

[0004] CN111472887A discloses a rack and pinion piston internal combustion engine technology. This engine technology adds a rack to the end of the piston of a traditional internal combustion engine that is far from the cylinder, and transmits power to the power output shaft through the rack. Although this increases the efficiency of power transmission, 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 rate 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 structure technology are that the gas turbine has a high cost, low energy conversion rate, and high noise.

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

[0007] (a) Technical problems to be solved

[0008] To address the technical problems of high vibration intensity, low energy conversion rate, and complex structure in existing engines, this invention aims to provide a stable, efficient, and energy-saving engine that, compared to existing technologies, exhibits stable vibration, simple structure, low cost, and high energy conversion rate.

[0009] (II) Technical Solution

[0010] To address the aforementioned problems, this invention provides an integrated engine device with a single cylindrical main shaft. The engine device comprises a gas distributor, a thrust burner, a cylindrical main shaft, a power cylinder, a compression cylinder, an auxiliary cylinder, a flat sector-shaped piston, a baffle plate base, and a baffle plate. While the power cylinder, compression cylinder, and auxiliary cylinder have slightly different dimensions, they share the same technical structure and shape. Each cylinder, including the power cylinder, compression cylinder, and auxiliary cylinder, has a flat sector-shaped piston installed inside, and each cylinder has a baffle plate base and a baffle plate installed externally. Furthermore, a thrust burner is added externally to all power cylinders, and a gas distributor is added externally to all compression cylinders.

[0011] The aforementioned compression cylinder can be provided in multiple ways as needed. In the specific embodiment of the present invention, only one compression cylinder is provided.

[0012] The number of working cylinders is limited to an even multiple of the number of compression cylinders. The number of working cylinders can be two, four, or six times the number of compression cylinders. In the specific embodiment of the present invention, there are four working cylinders, namely the first working cylinder, the second working cylinder, the third working cylinder, and the fourth working cylinder. The technical structure, shape, and size of the four working cylinders are the same.

[0013] The auxiliary cylinders are limited to an even multiple of the number of compression cylinders. The number of auxiliary cylinders can be two or four times the number of compression cylinders. In a specific embodiment of this invention, two auxiliary cylinders are provided: a left auxiliary cylinder and a right auxiliary cylinder. The two auxiliary cylinders have the same technical structure, shape, and dimensions.

[0014] Each cylinder, including compression cylinders, power cylinders, and auxiliary cylinders, consists of a composite cylinder, a left end cover, and a right end cover. The left and right end covers are installed on the left and right end faces of the composite cylinder. The shape, structure, and dimensions of the left and right end covers of each cylinder are identical. Both the left and right end covers have internal bushings, shaft holes, end cover cooling water chambers for cooling, end cover water inlets, and end cover water outlets. Water sealing plates are installed on the left and right end covers to seal the end cover cooling water chambers. Each composite cylinder has a baffle plate slot, a cylinder air inlet, a cylinder air outlet, 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 composite cylinder, a cylinder cooling water chamber for cooling, a cylinder water inlet, and a cylinder water outlet.

[0015] The gas distributor is equipped with a one-way valve, an inlet, a Y-shaped outlet pipe, and a pressure regulating valve. The inlet of the gas distributor is connected to the outlet of the composite cylinder of the compression cylinder. The distributor has two Y-shaped outlet pipes, one on the left and one on the right. Each Y-shaped outlet pipe has two single ports, and the distributor has a total of four single ports, which are respectively connected to the gas storage chamber inlets of the four thrust burners installed on the upper part of the power cylinders.

[0016] The thrust burners mounted on the upper part of the four power cylinders all have the same technical structure, shape, and specifications. Each thrust burner includes a gas storage chamber, combustion chamber, spark plug, fuel injector, left push rod, right push rod, left rocker arm, right rocker arm, left valve, right valve, thrust valve, left timing cam, right timing cam, thrust burner oil inlet, thrust burner oil outlet, vent, thrust burner water inlet for cooling, thrust burner water outlet, and thrust burner water passage. The right valve and left valve have the same shape, but the right valve stem is 4mm shorter than the left valve stem to ensure that the right and left valves have the same stroke driven by the left rocker arm. Both the right and left valves consist of three parts: the stem head, the stem body, and the tailstock. The stem head and stem body are fixed together, and the stem body and tailstock are tightened together with screws. The tailstock has a rectangular frame hole through which the right rocker arm passes, ensuring that the right valve, left valve, and right rocker arm do not contact each other during operation. The vent reduces air resistance and negative pressure behind the valve's thrust surface during operation, and also serves to drain engine oil. The gas storage chamber is equipped with a one-way valve, a gas storage chamber inlet, and a gas storage chamber exhaust port. The combustion chamber is equipped with a combustion chamber inlet and a combustion chamber exhaust port. The gas storage chamber inlet is connected to a single port of the "Y"-shaped outlet pipe of the distributor on the compression cylinder. The gas storage chamber exhaust port is connected to the combustion chamber inlet. The combustion chamber outlet is connected to the inlet of the compound cylinder of the power cylinder. The inlet of the compound cylinder of the left auxiliary cylinder is connected to the outlet of the compound cylinder of the first power cylinder and the outlet of the compound cylinder of the second power cylinder. The inlet of the compound cylinder of the right auxiliary cylinder is connected to the cylindrical outlet of the compound cylinder of the third power cylinder and the cylindrical outlet of the compound cylinder of the fourth power cylinder.

[0017] Although the specifications and dimensions of the flat sector-shaped piston, baffle plate, and baffle plate base installed on each of the cylinders are not exactly the same, their structural shapes are all the same.

[0018] The baffle base is installed in the baffle slot of the composite cylinder of the corresponding cylinder. The baffle base is provided with a base water inlet, a base water outlet, 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 for cooling. The front sealing door and the rear sealing door have the same shape, specifications, and dimensions.

[0019] The aforementioned baffle plate is installed inside a baffle plate base, which contains a spring. Under spring pressure, the baffle plate is pressed tightly against a flat, fan-shaped rotary plug inside the composite cylinder. The baffle plate is structurally composed of a round handle and a long plate. The long plate has left and right sealing plates on both sides, an oil hole in the middle, and a beveled arc shape at its bottom. This bevel ensures the baffle plate can move freely up and down when pushed by the arc of the flat, fan-shaped rotary plug, and also ensures a tight, airtight fit between the baffle plate and the plug. The left and right sealing plates on both sides of the baffle plate are the same shape as the sealing plates on the flat, fan-shaped rotary plug. Oil from inside the baffle plate base can enter the oil hole in the baffle plate. The front and rear sealing doors and the left and right sealing plates of the baffle plate within the baffle plate base ensure that the baffle plate installed within the base can both fit tightly against the inner wall of the baffle plate base and slide up and down, effectively preventing high-pressure gas inside the composite cylinder from leaking through the baffle plate slots. The baffle plate base, baffle plate, composite cylinder, and flat sector-shaped rotary plug allow for relatively flexible movement while maintaining excellent sealing.

[0020] The aforementioned flat sector-shaped rotary piston has a shaft hole. The outline of the flat sector-shaped rotary piston is in the shape of a sector, which is divided into four parts: the pushing arc surface, the far-stop pushing arc surface, the returning arc surface, and the near-stop pushing arc surface. The radius of curvature of the arc surface of the far-stop pushing arc surface is equal to the radius of curvature of the circular hole surface in the inner cavity of the composite cylinder. The length of the far-stop pushing arc surface of the flat sector-shaped rotary piston is set to be more than four times the diameter of the air inlet on the composite cylinder of the power cylinder. With this technical feature, it is ensured that each time the flat sector-shaped rotary piston rotates past the air inlet of the composite cylinder, its far-stop pushing arc surface can dynamically seal the air inlet of the composite cylinder of the power cylinder for a short period of time, so as to facilitate the compressed air entering the combustion chamber to fully mix and burn with the fuel without leakage or pressure reduction during the short period of time.

[0021] The flat sector-shaped rotary plug is installed inside the composite cylinder of the cylinder. The two sides and the far-stopping arc surface of the flat sector-shaped rotary plug are closely fitted with the left and right end caps and the inner wall curved surface of the composite cylinder, respectively. It can also rotate flexibly. When the flat sector-shaped rotary plug rotates inside the composite cylinder, during the process of mutual contact and pushing with the baffle plate, the pushing arc surface of the flat sector-shaped rotary plug pushes the baffle plate to the upper part of the inner cavity curved surface of the composite cylinder, opening the rotation path of the flat sector-shaped rotary plug. After the flat sector-shaped rotary plug passes through, the baffle plate falls back under the pressure of the spring.

[0022] The flat, fan-shaped rotary piston has two rows of sealing plates on its far-stop arc surface and on its left and right sides. Each row has two sealing plates, one on the left and one on the right. The sealing plates are installed in grooves, and springs are installed in the grooves to provide elastic force to the sealing plates. Oil holes are located on the far-stop arc surface and on the left and right sides of the flat, fan-shaped rotary piston, and tiny oil holes are located in the grooves.

[0023] During the rotation of the flat sector-shaped piston within the composite cylinder, the flat sector-shaped piston and the baffle plate consistently divide the inner cavity of the composite cylinder into two different types of states: one where the air inlet and outlet of the composite cylinder are not connected, and the other where the air inlet and outlet of the composite cylinder are connected. These two states alternately increase and decrease, ensuring that the air intake and compression strokes of the flat sector-shaped piston in the compression cylinder and the power and exhaust strokes of the flat sector-shaped piston in the power cylinder are performed synchronously and continuously. Following the rotation direction of the flat sector-shaped piston: (i) When the baffle plate inside the compound cylinder of the compression cylinder and the flat sector-shaped piston are not connected to the inlet and outlet of the compound cylinder, the flat sector-shaped piston causes the compression cylinder to draw in air from the inlet of the compound cylinder and simultaneously pressurize gas into the gas distributor from the outlet of the compound cylinder. When the inlet and outlet of the compound cylinder of the compression cylinder are connected, the flat sector-shaped piston ends the intake and compression stroke of the compression cylinder. (ii) When the baffle plate inside the compound cylinder of the power cylinder and the sector-shaped piston are not connected to the inlet and outlet of the cylinder, the high-pressure gas from the combustion chamber rushes into the cavity between the flat sector-shaped piston and the baffle plate from the inlet of the compound cylinder of the power cylinder. The flat sector-shaped piston is driven by the high-pressure gas to rotate and perform work. At the same time, the flat sector-shaped piston also sweeps out the waste gas along the way from the outlet of the cylinder. When the cylinder inlet and cylinder outlet are connected, the high-pressure gas inside the compound cylinder of the power cylinder is discharged from the cylinder outlet, and the working stroke of the flat sector-shaped piston in the power cylinder and the scavenging of waste gas are completed. (III) The working stroke of the baffle plate and flat sector-shaped piston in the compound cylinder of the two auxiliary cylinders is consecutive with the working stroke of the baffle plate and sector-shaped piston in the compound cylinder of the power cylinder. When the flat sector-shaped piston in the compound cylinder of the power cylinder finishes rotating and exhausting, the cylinder inlet of the auxiliary cylinder is connected to the gas discharged from the cylinder outlet, which continues to drive the flat sector-shaped piston in the auxiliary cylinder to rotate and work. When the flat sector-shaped piston in the compound cylinder of the power cylinder starts rotating and working again, the rotating working stroke of the flat sector-shaped piston in the auxiliary cylinder ends, and only the exhaust stroke follows.

[0024] The engine of the present invention comprises only one cylindrical main shaft. This main shaft passes through the shaft holes of the left end cap bushing, right end cap bushing, and flat sector-shaped piston within the composite cylinder of each cylinder, including the power cylinder, auxiliary cylinder, and compression cylinder. The flat sector-shaped pistons in each cylinder, connected in series on the main shaft, are each fixedly mounted on the main shaft with a key. The timing cams of each thrust burner are also fixedly mounted on the main shaft with keys, providing timing thrust to the pushrods and rocker arms outside the power cylinder. A flywheel and pulley are also mounted on the main shaft. Finally, the front and rear ends of the main shaft pass through the housing bushing and are mounted on the engine housing of the present invention. The housing bushing has an oil hole. Thus, using a single cylindrical main shaft, all the cylinders of the present invention and the components installed inside and outside the cylinders are connected in series and assembled into a single unit.

[0025] The main shaft is provided with a central axis oil passage and radial oil holes. The central axis oil passage of the main shaft is connected to the radial oil holes, the housing bushing oil holes, and the flat fan-shaped piston oil holes.

[0026] The power cylinder, auxiliary cylinder, and compression cylinder, which are connected in series on the main shaft, have the following phase relationship in the apparent plane: with one compression cylinder at the center of the main shaft, an equal number of power cylinders and auxiliary cylinders of the same specifications and size are installed symmetrically on both its left and right sides. The specific arrangement of the cylinders connected in series on the main shaft, with one compression cylinder as the center, and symmetrically installed on both its left and right sides, in the following order from left to right: first power cylinder, second power cylinder, left auxiliary cylinder, compression cylinder, right auxiliary cylinder, third power cylinder, and fourth power cylinder.

[0027] The phase relationship between the flat sector-shaped pistons in each cylinder of the present invention, which are serially installed on the main rotating shaft, in the apparent plane is as follows: the far-stop arc surface of the flat sector-shaped piston profile in the first working cylinder faces upward; the far-stop arc surface of the flat sector-shaped piston profile in the second working cylinder faces downward; the far-stop arc surface of the flat sector-shaped piston profile in the left auxiliary cylinder faces downward; the far-stop arc surface of the flat sector-shaped piston profile in the compression cylinder faces upward; the far-stop arc surface of the flat sector-shaped piston profile in the right auxiliary cylinder faces downward; the far-stop arc surface of the flat sector-shaped piston profile in the third working cylinder faces downward; and the far-stop arc surface of the flat sector-shaped piston profile in the fourth working cylinder faces upward. The technical features of this layout ensure that the centrifugal forces of the flat sector pistons in the four power cylinders cancel each other out during rotation; and ensure that the centrifugal force of the flat sector piston in the compression cylinder cancels out the centrifugal force between the flat sector pistons in the left auxiliary cylinder and the right auxiliary cylinder, thereby reducing engine vibration intensity.

[0028] When the engine device of the present invention is working, the flat sector-shaped pistons in the four power cylinders, the flat sector-shaped pistons in the compression cylinders, and the flat sector-shaped pistons in the two auxiliary cylinders rotate synchronously on the same main shaft. The flat sector-shaped pistons in the compression cylinders draw air into the compression cylinders on one side and compress the air into the gas distributor on the other side. The gas distributor sends the compressed high-pressure air into the gas storage chamber of the thrust burner on each power cylinder through a "Y"-shaped outlet pipe. At this time, the thrust valves, left valves, and right valves of each thrust burner remain stationary. The air passage between the outlet of the gas storage chamber and the inlet of the combustion chamber is closed. The sealing effect of the right valve on the air passage connected to the outlet of the gas storage chamber prevents compressed air in the gas storage chamber from prematurely entering the air passage connected to the inlet of the combustion chamber, thus forcing open the left valve and causing a leakage effect. After the working stroke of compressed air entering the gas storage chamber is completed, the inlet of the gas storage chamber is closed by a one-way valve, preventing the compressed air in the gas storage chamber from flowing back to the distributor. Furthermore, the left and right push rods, left and right rocker arms outside each power cylinder, driven by their respective timing cams, push the left valve, right valve, and thrust valve on the thrust burner, opening the exhaust port of the gas storage chamber and the inlet of the combustion chamber, pushing compressed air into the combustion chamber. At the same time, the far-end stroke of the flat sector piston in each power cylinder... The arc section NR from point N to point R on the curved surface precisely seals the compound cylindrical air inlet and the combustion chamber exhaust port of the cylinder. Further, after the left and right valves reset and close the intake passage above the combustion chamber, the push valve resets, the fuel injector injects fuel into the combustion chamber to form a combustible mixture, the spark plug releases a spark, and the combustible mixture burns to produce high-temperature and high-pressure gas. At this time, the far-stopping arc section of the rotating flat sector-shaped piston in the power cylinder has just completely rotated through the compound cylindrical air inlet of the cylinder, opening the compound cylindrical air inlet and the combustion chamber exhaust port. The high-temperature and high-pressure gas simultaneously rushes towards the flat sector-shaped piston and the baffle plate. Since the high-temperature and high-pressure gas cannot push the baffle plate, and the baffle plate has good sealing properties, the high-temperature and high-pressure gas pushes the flat sector-shaped piston, the main shaft, and the flywheel to rotate and perform work. At the same time, as the flat sector-shaped piston rotates, the temperature and pressure of the high-temperature and high-pressure gas gradually decrease. After the flat sector-shaped piston rotates past the composite cylinder outlet of the cylinder, the high-temperature and high-pressure gas, after being cooled and depressurized, is discharged through the composite cylinder outlet and then enters the auxiliary cylinder to further exert thrust on the flat sector-shaped piston inside the auxiliary cylinder.The cooled and depressurized high-temperature, high-pressure gas discharged from the outlet of the compound cylinder of the first working cylinder and the cooled and depressurized high-temperature, high-pressure gas discharged from the outlet of the compound cylinder of the second working cylinder enter the left auxiliary cylinder, further exerting a thrust on the flat-plate sector-shaped piston inside the left auxiliary cylinder. Similarly, the cooled and depressurized high-temperature, high-pressure gas discharged from the outlet of the compound cylinder of the third working cylinder and the cooled and depressurized high-temperature, high-pressure gas discharged from the outlet of the compound cylinder of the fourth working cylinder enter the right auxiliary cylinder, further exerting a thrust on the flat-plate sector-shaped piston inside the right auxiliary cylinder. Finally, the high-temperature, high-pressure gas, whose temperature and pressure have decreased to a lower level, is discharged as waste gas from the outlet of either the left or right auxiliary cylinder, enters the filter stack for purification, and is then discharged into the atmosphere. Residual oil droplets in the waste gas are filtered and returned to the oil pan, while small particles are separated, collected, and periodically removed. The entire working process begins with the compression of air by the compressor cylinder, followed by the combustion of the combustible mixture to produce high-temperature, high-pressure gas that drives the flat-plate sector-shaped piston, main shaft, and flywheel to rotate and perform work. Finally, the waste gas is filtered through the collection and fume hood and then discharged, completing one working cycle. The collection and fume hood is installed at the bottom of the machine housing and is used to discharge waste gas. It has a filter chamber, a sedimentation cup, and a filter cup, which can effectively filter and collect residual oil droplets and small particles mixed in with the waste gas. The residual oil droplets are returned to the oil pan after filtration, and the small particles are collected and periodically removed. The gas distributor outside the compressor cylinder is equipped with a pressure regulating valve that also functions as a safety valve, which can adjust the pressure of the high-pressure gas in the gas distributor according to different technical requirements.

[0029] The engine device of this invention uses a compression cylinder to perform the intake and compression strokes of air, and then inputs the compressed air into the combustion chamber through a gas distributor and an air storage chamber. The power cylinder performs the work strokes of the high-temperature, high-pressure gas after combustion and the exhaust strokes. Therefore, during the operation of the engine device of this invention, the four working strokes of intake, compression, power, and exhaust are performed simultaneously. The intake and compression functions of the compression cylinder and the power and exhaust functions of the power cylinder are independent of each other. The specifications and dimensions of the compound cylinder and flat sector-shaped piston of the compression cylinder, as well as the specifications and dimensions of the combustion chamber, can be set as needed. The specifications and dimensions of the compound cylinder and flat sector-shaped piston of the compression cylinder determine the effective working volume of the compression cylinder; the specifications and dimensions of the combustion chamber determine the effective working volume of the combustion chamber. 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 this invention. Therefore, the engine device of this invention can achieve a large compression ratio. Furthermore, the left and right auxiliary cylinders and their respective internal flat sector-shaped rotary cylinders in the engine device of the present invention can be replaced by two left and right counterweight iron blocks of the same shape and weight, respectively. During operation, the high-temperature and high-pressure gas discharged from the outlets of the first power cylinder, the second power cylinder composite cylinder, the third power cylinder, and the fourth power cylinder after cooling and depressurization directly enters the filter chimney for purification before being discharged into the atmosphere. With this technical measure, the technical feature of the engine device of the present invention can be applied to low-power models is ensured.

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

[0031] Compared with existing engine technologies, the engine of this invention utilizes a thrust burner, distributor, power cylinder, auxiliary cylinder, compression cylinder, flat sector piston, baffle plate, and a main shaft for operation. It does not require the piston, connecting rod, and crankshaft to convert reciprocating linear motion into rotary motion, nor does it require the triangular rotor to rotate eccentrically within an elliptical cylinder, nor does it require the compression of a compressor and the conversion of a turbine. Therefore, compared with existing engine devices, it has the advantages of simple structure, low cost, stable overall operation, low vibration, high compression ratio, and high energy conversion rate.

[0082] Example 1

[0083] As shown in Figure 1, the oil tank 1 is mounted on the housing 15, the speed governor 2 is mounted on the main shaft 20, and the main shaft 20 is mounted on the housing 15 through a bushing 139 with an oil hole. The oil supply pump 4 is mounted on the housing 15 through a reinforcing rib 3 and is connected to the main shaft 20. Four gas-driven burners 5 with the same structure, shape, specifications, and size are respectively mounted 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 mounted on the compression cylinder 9, and the water tank 14 is mounted on the housing 15. All cylinders are connected in series on the main shaft 20 through bushings 139 on the left and right end caps 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 mounted symmetrically on the left and right sides centered on the compression cylinder 9. Four power cylinders, one compression cylinder, and two auxiliary cylinders are all fixed to the housing 15 by reinforcing ribs. Flat sector-shaped pistons 21 are respectively installed inside the first power cylinder 6, the second power cylinder 7, the left auxiliary cylinder 8, the compression cylinder 9, the right auxiliary cylinder 11, the third power cylinder 12, and the fourth power cylinder 13. All flat sector-shaped pistons 21 are installed on the main shaft 20 by flat keys. The oil cooler 16, water pump 22, starter motor 23, and battery 17 are all installed on the housing 15. The oil pump 19 is installed on the housing 15 by reinforcing ribs and engages with the main shaft 20. The flywheel 18 is installed on the main shaft 20 by flat keys and nuts. The pulley 24 is installed on the flywheel 18. The oil pan 141 is installed at the bottom of the housing 15. All the cylinders mentioned above, including the power cylinder, compression cylinder, and auxiliary cylinder, are of three different functional types. Although their specifications and sizes are not exactly the same, their technical structure and shape are identical. Among them, the four power cylinders have the same structure, shape, specifications, and size, and the two auxiliary cylinders also have the same structure, shape, specifications, and size.

[0084] Referring to Figures 2 and 3, the left and right end caps 37 installed on both ends of the composite cylinder 25 of the first working cylinder 6 have the same shape, structure, and size. The flat sector-shaped rotary plug 21 installed inside the composite cylinder 25 is mounted on the main rotating shaft 20 via a flat key. The two sides and the far-stopping arc surface of the flat sector-shaped rotary plug 21 of the composite cylinder 25 are closely fitted with the left and right end caps 37 installed inside 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 inside the composite cylinder 25 and is closely fitted with the outer edge surface of the flat sector-shaped rotary plug 21, and can slide. The technical features of the first working cylinder 6 described above are the same as the technical features of the flat sector-shaped pistons and composite cylinders 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] Referring to Figures 4 and 5, the composite cylinder 25 is provided with a cylindrical air inlet 29, a cylindrical cooling water chamber 30 for connecting cooling water channels, an annular water sealing plate platform 31, an annular platform 32, a left platform 33, a right platform 34, a cylindrical air outlet 35, and a baffle plate slot 36. The baffle plate slot 36 is used to install the baffle plate 28, and its cylindrical air outlet 35 is used to discharge exhaust gas. Figure 5 is a schematic diagram of the various technical features provided on the composite cylinder 25 of the first working cylinder shown in Figure 4 from the left view. These technical features of the composite cylinder 25 of the first working cylinder are the same as the technical features of 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.

[0086] Referring to Figures 6 and 7, the right end cap 37 of the composite cylinder 25 of the first working cylinder 6 is provided with an end cap cooling water chamber 38, an end cap cooling water inlet 39, and an end cap cooling water outlet 40 for cooling, and a bushing 139 for connecting the main rotating shaft. These technical features of the left and right end caps 37 of the composite cylinder 25 of the first working cylinder 6 are the same as the technical features of the left and right end caps of 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.

[0087] Referring to Figures 8, 9, 10, and 11, the sealing plate 41 is tightened onto the left or right end cover 37 with screws to seal the cooling water cavity 38 of the end cover. The sealed left or right end cover 37 is then fixedly installed on the left platform 33 and right platform 34 of the composite cylinder 25 with screws. The annular sealing plate 42 is fixedly installed on the annular sealing plate platform 31 of the composite cylinder 25 with screws to seal the cooling water cavity 30 of the cylinder. The annular platform 32 is used to strengthen the load-bearing capacity of the composite cylinder 25. The right sealing plate has the same shape and size as the left sealing plate. These technical features of the first working cylinder 6 are the same as the technical features of the various composite cylinders of the second working cylinder 7, third working cylinder 12, fourth working cylinder 13, left auxiliary cylinder 8, compression cylinder 9, and right auxiliary cylinder 11 of the present invention.

[0088] Referring to Figures 12, 13, 14, 15, 16, and 17, the flat sector-shaped rotary plugs 21 installed in each of the cylinders, although varying in size, all share the same structural shape. The flat sector-shaped rotary plug 21 is installed within the composite cylinder of its respective cylinder and can rotate freely. It features a shaft hole 48, a keyway 45, a remote stop-thrust surface oil hole 46, and a side end oil hole 47. The keyway 45 is used to fix the position of the flat sector-shaped rotary plug 21 on the main shaft 20. The remote stop-thrust surface oil hole 46 and the side oil hole 47 communicate with the radial oil holes on the main shaft 20 to ensure that the flat sector-shaped rotary plug 21 receives oil lubrication during operation.

[0089] The flat sector-shaped rotary plug 21 has two rows of sealing plates installed on both sides. Each row of sealing plates consists of a left sealing plate 44 and a right sealing plate 43. The left sealing plate 44 has a left notch 53 at its outer end, and the right sealing plate 43 has a right notch 54 at its outer end. When the flat sector-shaped rotary plug 21 is installed in the working cylinder, the left notch 53 and the right notch 54 are interlocked. Each sealing plate is installed in a groove, which has tiny oil holes to facilitate oil lubrication. Springs are also installed in the grooves. 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 pressed tightly against the surface of the workpiece, ensuring good sealing performance of the flat sector-shaped rotary plug 21 after installation in the working cylinder.

[0090] The flat sector-shaped rotary piston 21 has a fan-shaped profile. In a clockwise direction, from point M49 to point N50 is the pushing arc section MN of the flat sector-shaped rotary piston 21 profile; from point N50 to point R51 is the far-stopping arc section NR of the flat sector-shaped rotary piston 21 profile; from point R51 to point Y52 is the playing arc section RY of the flat sector-shaped rotary piston 21 profile; and from point Y52 to point M49 is the near-stopping arc section YM of the flat sector-shaped rotary piston 21 profile. The radius of curvature of the far-stopping arc section NR is related to the radius of curvature of the composite cylinder in which it is located. The radii of curvature of the inner circular bore surfaces are equal. The length of the far-stopping arc surface NR section of the flat sector rotary piston 21 is set to be four to six times the diameter of the cylindrical air inlet 29 on the power cylinder compound cylinder 25. With this technical feature, it is ensured that the far-stopping arc surface NR section of the flat sector rotary piston 21 can dynamically seal the air inlet 29 of the compound cylinder for a short period of time during each rotation of the compound cylinder air inlet 29. This facilitates the compressed air entering the combustion chamber 86 to fully mix and burn with the fuel without leakage or pressure reduction during a short period of time.

[0091] When the flat sector-shaped rotary plug 21 rotates inside the composite cylinder, during the process of mutual contact and pushing with the baffle plate 28, the MN segment of the pushing arc surface of the flat sector-shaped rotary plug 21 pushes the baffle plate 28 to the upper part of the curved surface inside the composite cylinder, thereby opening the rotation path of the flat sector-shaped rotary plug 21. After the flat sector-shaped rotary plug 21 passes, the baffle plate 28 falls back under the pressure of the spring. These technical features of the flat sector-shaped rotary plug 21 in the first working cylinder 6 are the same as the technical features of the flat sector-shaped 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] Referring to Figures 18 and 19, the main shaft 20 is provided with a central axis oil passage 55, and multiple radial oil holes 56 are also provided at the outer diameter of the main shaft 20. The central axis oil passage 55 of the main 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 fan-shaped plug.

[0093] Referring to Figure 20, the far-end thrust arc surface 57 of the flat sector-shaped piston in the first power cylinder 6, mounted on the main shaft 20, faces upwards, and the centrifugal force F158 generated during its rotation is upwards. The far-end thrust arc surface 59 of the flat sector-shaped piston in the second power cylinder 7 faces downwards, and the centrifugal force F260 generated during its rotation is downwards. The far-end thrust arc surface 61 of the flat sector-shaped piston in the third power cylinder 12 faces downwards, and the centrifugal force F362 generated during its rotation is downwards. The far-end thrust arc surface 63 of the flat sector-shaped piston in the fourth power cylinder 13 faces upwards, and the centrifugal force F464 generated during its rotation is upwards. The centrifugal forces generated by the flat sector-shaped pistons in these four power cylinders during rotation generally cancel each other out. This arrangement can reduce the vibration intensity of the engine.

[0094] Referring to Figure 21, the distal end of the rotary piston in the compressor cylinder 9 faces upward, and the centrifugal force F566 generated during its rotation is upward. The distal end of the rotary piston in the left auxiliary cylinder 8 faces downward, and the centrifugal force F668 generated during its rotation is downward. The distal end of the rotary piston in the right auxiliary cylinder 11 faces downward, and the centrifugal force F770 generated during its rotation is downward. The centrifugal forces F668 and 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, thus canceling each other out. This arrangement can reduce the vibration intensity of the engine.

[0095] Referring to Figure 22, the thruster burner 5 is mounted on the composite cylinder 25 of the power cylinder. A pivotable left rocker arm 73 and right rocker arm 74 are mounted on the support column 94 of the thruster burner 5. A left push rod 71 and a right push rod 72 pass through the outer wall of the thruster burner and are respectively mounted on their respective cams and rocker arms. The left rocker arm 73 is pushed by the left timing cam 93 and the left push rod 71, thus exerting a thrust 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 push rod 72. The left valve 75 and right valve 76 have the same structural shape, but the rod length of the right valve 76 is 4mm shorter than that of the left valve 75, so that the strokes of the right valve 76 and left valve 75 pushed by the left rocker arm 73 are equal. After the right rocker arm 74 passes through the rectangular frame hole 96 on the right valve 76 and left valve 75, it can ensure that the right valve 76, left valve 75, and right rocker arm 74 do not contact each other during operation. The right timing cam 92 and left timing cam 93 are both mounted on the main shaft 20 with flat keys. The oil inlet 78 and oil outlet 140 of the thrust burner are connected to the oil pipe, and the air vent 79 of the thrust burner not only discharges oil but also reduces the air resistance and negative pressure behind the thrust surface of the thrust valve 77 during operation. The gas storage chamber 82 is equipped with a gas storage chamber inlet 81, a gas storage chamber exhaust port 83, and a gas storage chamber check valve 80 to prevent the high-pressure gas in the gas storage chamber 82 from backflowing through the gas storage chamber inlet 81. The combustion chamber 86 is equipped with a combustion chamber inlet 84, a combustion chamber exhaust port 89, a fuel injector 90, and a spark plug 91. The thruster burner water inlet 85, the thruster burner water outlet 87, and the thruster burner water channel 88 are used to connect to the cooling water channel to cool the combustion chamber 86. The combustion chamber exhaust port 89 is connected to the air inlet 29 on the compound cylinder 25 of the power cylinder. These technical features of the thruster burner 5 of the first power cylinder 6 are the same as the technical features of the thruster burners on the second power cylinder 7, the third power cylinder 12, and the fourth power cylinder 13 of the present invention.

[0096] Referring to Figure 23, the baffle base 95 is installed on the power cylinder 6, and the baffle 28 is installed inside the baffle base 95. When the far-stopping arc surface between the N point 50 and the R point 51 of the flat sector-shaped rotary piston 21 is exactly at the corresponding position of the closed intake port 29, compressed gas begins to be introduced into the combustion chamber 86. After this working stroke is completed, fuel is injected to form a combustible mixture. When the R point 50 rotates counterclockwise just past the intake port 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 compound cylinder 25 of the power cylinder from the exhaust port 89 and the cylindrical intake port 29, pushing the flat sector-shaped rotary piston 21 to rotate and perform work. The structural and technical features of the baffle base 95, baffle 28, and flat sector-shaped rotary plug 21 of the first working cylinder 6 are the same as the structural and operational features of the baffle base, baffle, and flat sector-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] Referring to Figure 24, which shows the specific structural shape of the left rocker arm 73 of the thruster burner 5 in a particular application.

[0098] Referring to Figure 25, which shows the specific structural shape of the right rocker arm 74 of the thruster burner 5 in a particular application.

[0099] Referring to Figures 26 and 27, which show the specific structural shape of the left valve 75 of the thrust burner 5 in a practical application, the right valve 76 has the same structural shape as the left valve 75. Both are composed of three parts: a rod head 127, a rod body 128, and a tail frame 129. The rod head 127 and the rod body 128 are fixed together, and the rod body 128 and the tail frame 129 are tightened together with screws. The tail frame 129 has a rectangular frame hole 96.

[0100] Referring to Figures 28, 29, and 30, the thrust valve 77 of the thrust burner 5 is composed of a cylinder 130 with a small-diameter disc 131 mounted on the upper end and a large-diameter disc 132 mounted on the lower end. The cylinder has threads at both ends, and the two discs have threaded holes in their centers. The cylinder and the two discs are tightened together by screws. The cylinder has a central oil passage 97, and the large-diameter disc 132 has three sealing spring rings 98 installed in an annular groove. The annular groove has radial holes communicating with the central oil passage 97. Figure 29 is a partial structural diagram of the thrust valve 77 in the D direction of Figure 28. The central oil passage 97 has an opening 137 on the outer diameter surface of the cylinder for communicating with the oil chamber 99 of the thrust burner. Figure 30 is a schematic diagram of the thrust valve in the R direction of Figure 28.

[0101] Referring to Figure 31, the central oil passage 97 of the thrust valve 77 is connected to the oil chamber 99 on the thrust burner 5, as well as the oil inlet 78 and oil outlet 140. The three sealing spring rings 98 can be lubricated by the oil output from the oil pump. The vent 79 can reduce the air resistance and negative pressure behind the thrust surface of the thrust valve 77 during operation, and the vent 79 also serves to discharge oil.

[0102] Referring to Figures 32, 33, 34, and 35, the base water inlet 100, base cooling water channel 102, and base water outlet 104 of the baffle base 95 are interconnected, allowing access to the cooling water circulation path for cooling the baffle base 95 during operation. The oil inlet pipe 101 and oil outlet pipe 103 can be connected to the lubricating oil circulation path to provide lubricating oil to the baffle 28 during operation, reducing friction during its movement. The front sealing door 106 and the rear sealing door 105 have identical structures, shapes, and dimensions. The front sealing door 106 and the rear sealing door 105 are always tightly pressed against the front and rear surfaces of the baffle 28 to ensure a tight seal between the front and rear surfaces of the baffle 28 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 pressed tightly against the flat sector-shaped rotary plug inside the composite cylinder by the spring pressure. The baffle 28 is fixedly composed of two parts: a round handle 133 and a long plate 134. A left sealing plate 44 and a right sealing plate 43 are provided on both sides of the long plate 134. An oil hole 136 is provided in the middle of the long plate 134. The bottom end of the long plate 134 is shaped like a sloping arc surface 135. The sloping arc surface 135 ensures that the baffle 28 can move flexibly up and down when pushed by the pushing arc surface of the flat sector-shaped rotary plug 21, and also ensures that the baffle 28 and the flat sector-shaped rotary plug 21 fit tightly without 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-shaped rotary plug. Oil inside the baffle base 95 can enter the oil hole of the baffle 28. The front sealing door 106, rear sealing door 105, and left and right sealing plates of the baffle plate 28 within the baffle plate base 95 ensure that the baffle plate installed within the baffle plate base can both fit tightly against the inner wall of the baffle plate base and slide up and down, effectively preventing high-pressure gas in the composite cylinder from leaking through the baffle plate slots. The baffle plate base, baffle plate, composite cylinder, and flat fan-shaped rotary plug can move relatively flexibly while maintaining excellent sealing. These structural and technical features of the baffle plate base 95 and baffle plate 28 of the first working cylinder 6 are identical to the structural and technical features of the baffle plate bases and baffle plates of the second working cylinder 7, third working cylinder 12, fourth working cylinder 13, left auxiliary cylinder 8, compression cylinder 9, and right auxiliary cylinder 11 of this invention.

[0104] Referring to Figures 36, 37, and 38, the baffle base 95 is installed on the upper part of the compressed cylinder 9, and the gas distributor 10 is installed on the upper part of the outlet 35 of the compressed cylinder 9. The gas distributor 10 is equipped with a distributor “Y”-shaped outlet pipe 107, a distributor inlet 138, a distributor pressure regulating valve 108, and a distributor check valve 109. The gas distributor 10 has two “Y”-shaped outlet pipes 107 on the left and right, 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 in the gas distributor according to different technical requirements. The distributor check valve 109 can prevent the compressed gas in the distributor from flowing back. When the flat sector-shaped piston in the compression cylinder 9 rotates counterclockwise, the arc surface of the flat sector-shaped piston where the arcs of point M49 and point N50 are located always compresses the air into the gas distribution chamber 10 through the cylinder outlet 35 and the distributor inlet 138. Then, the compressed high-pressure air is input into the gas storage chamber of each propeller through the distributor “Y”-shaped outlet pipe 107. The arc surface of the flat sector-shaped piston where the arcs of point R51 and point Y52 are located always draws air into the compression cylinder 9 from the compression cylinder inlet 29.

[0105] Referring to Figure 39, the outlets 35 of the first working cylinder 6 and the second working cylinder 7, and the inlet 29 of the left auxiliary cylinder 8, are all connected to the merging pipe 110. During operation, when the flat sector-shaped pistons in the first working cylinder 6 and the second working cylinder 7 simultaneously rotate past their respective compound cylindrical outlets 35, the cooled and depressurized high-temperature, high-pressure gas passes through the cylindrical outlet 35 and then enters the left auxiliary cylinder 8 through the inlet 29, further exerting a thrust on the flat sector-shaped piston 21 within the left auxiliary cylinder 8. During this process, the temperature and pressure of the high-temperature, high-pressure gas gradually decrease to waste gas, and finally, it enters the filter stack from the outlet 35 of the left auxiliary cylinder 8, is purified and filtered, and then discharged into the atmosphere. The linkage working characteristics of the first working cylinder 6, the second working cylinder 7, and the left auxiliary cylinder 8 are the same as those of the third working cylinder 12, the fourth working cylinder 13, and the right auxiliary cylinder 11.

[0106] Referring to Figures 40 and 41, during the rotation of the flat sector-shaped rotary piston 21 within the composite cylinder 25, the flat sector-shaped rotary piston 21 and the baffle plate 28 always divide the inner cavity of the composite cylinder 25 into two different types of states: one type is where the cylinder inlet 29 and cylinder outlet 35 of the composite cylinder are not connected, and the other type is where the cylinder inlet 29 and cylinder outlet 35 are connected. These two states occur in a cyclical, alternating pattern, ensuring that the intake and compression strokes of the flat sector-shaped rotary piston 21 in the compression cylinder and the power and exhaust strokes of the flat sector-shaped rotary piston 21 in the power cylinder are performed synchronously and continuously. Following the rotation direction of the flat sector-shaped rotary plug 21: (i) When the baffle plate 28 inside the composite cylinder of the compression cylinder 9 and the flat sector-shaped rotary plug 21 prevent the composite cylinder inlet 29 from being connected to the cylinder outlet 35, the flat sector-shaped rotary plug 21 causes the compression cylinder 9 to draw in air from the composite cylinder inlet 29, and at the same time, it also compresses gas from the composite cylinder outlet 35 and the distributor inlet 138 to the gas distributor 10. When the composite cylinder inlet 29 and the cylinder outlet 35 of the compression cylinder 9 are connected to each other, the flat sector-shaped rotary plug 21 causes the compression cylinder 9 to finish its intake and compression stroke. (ii) When the baffle plate 28 and the flat sector-shaped rotary plug 21 in the composite cylinder of the power cylinder are not connected to the cylinder inlet 29 and the cylinder outlet 35, the high-pressure gas from the combustion chamber 86 rushes from the cylinder inlet 29 of the composite cylinder 25 of the power cylinder into the cavity between the flat sector-shaped rotary plug 21 and the baffle plate 28. The flat sector-shaped rotary plug 21 is driven by the high-pressure gas to rotate and do work. At the same time, the flat sector-shaped rotary plug 21 also sweeps the waste gas along the way out of the cylinder outlet 35. When the cylinder inlet and cylinder outlet are connected, the high-pressure gas inside the composite cylinder of the power cylinder is discharged from the cylinder outlet 35. The working stroke of the flat sector-shaped piston 21 in the power cylinder and the scavenging of waste gas are completed. (III) The working stroke of the baffle plate and flat sector-shaped piston in the composite cylinder of the two auxiliary cylinders is consecutive with the working stroke of the baffle plate and sector-shaped piston in the composite cylinder of the power cylinder. When the flat sector-shaped piston 21 of the composite cylinder of the power cylinder finishes rotating and exhausting, the cylinder inlet 29 in the auxiliary cylinder is connected to the gas discharged from the cylinder outlet 35, which continues to drive the flat sector-shaped piston 21 in the auxiliary cylinder to rotate and work. When the flat sector-shaped piston 21 of the composite cylinder of the power cylinder starts rotating and working again, the rotating working stroke of the flat sector-shaped piston 21 in the auxiliary cylinder ends, and only the exhaust stroke follows.

[0107] Referring to Figure 42, the filter chimney 116 is installed at the bottom of the housing 15. The structure of the filter chimney 116 consists of the right air inlet 111, the left air inlet 118, the first filter chamber 112, the second filter chamber 113, the third filter chamber 114, the fourth filter chamber 125, the right sedimentation cup 115, the left sedimentation cup 119, the middle sedimentation cup 121, the filter cup 123, the return oil pipe 124, the slag removal bolt 117, the left self-opening valve 120, the right self-opening valve 122, and the exhaust port 126. During operation, waste gas discharged from the outlet of the right auxiliary cylinder 11 enters the right air inlet 111 of the filter chimney 116; waste gas discharged from the outlet of the left auxiliary cylinder 8 enters the left air inlet 118 of the filter chimney 116. The two streams of waste gas merge into one in the first filter chamber 112, then turn and flow into the second filter chamber 113, the third filter chamber 114, and the fourth filter chamber 125, before being discharged into the atmosphere. During this process, residual oil droplets and tiny particles in the waste gas bend and collide with the filter chamber walls as the airflow travels, thus settling and accumulating in the right sediment collection cup 115, the left sediment collection cup 119, and the middle sediment collection cup 121. The left self-opening valve 120 and the right self-opening valve 122 have the same structure, both having the function of closing when subjected to flowing waste gas pressure, and automatically opening by spring force when the engine is stopped and there is no flowing waste gas pressure. The left and right automatic start valves 120 and 122 are closed when the engine is running and open when the engine is stopped. This allows residual oil droplets that have settled in the three cups (right, left, and middle) to flow to the filter cup 123 when the engine is stopped. The residual oil filtered by the filter cup 123 flows back into the oil pan through the return pipe 124. When the engine is running, the left and right automatic start valves are closed, so the exhaust gas flowing through the filter chimney 116 will not enter the oil pan. The particulate matter in the three cups is periodically removed by unscrewing the cleaning bolt 117.

[0108] Based on the technical features of all the above-mentioned components, when the integrated engine device with a cylindrical main shaft in series of the present invention is working, the starter motor 23 is first energized and started. The starter motor 23 then drives the main shaft 20 and the energy storage flywheel 18 to start rotating. The flat sector-shaped pistons in the four power cylinders, the flat sector-shaped pistons in the compression cylinder, and the flat sector-shaped pistons in the two auxiliary cylinders rotate synchronously on the same main shaft 20. The flat sector-shaped piston 21 in the compression cylinder 9 draws air into the compression cylinder 9 through the air inlet 29, and at the same time compresses the air into the gas distributor 10. The gas distributor 10, through the distributor "Y"-shaped outlet pipe 107, inputs the compressed air into the gas storage chamber 82 of the thrust burner on each power cylinder. At this time, the thrust valves 77, left valve 75, and right valve 76 of each thrust burner remain stationary. The ventilation passage between the exhaust port 83 of the gas storage chamber 82 and the air inlet 84 of the combustion chamber 86 is closed. The sealing effect of the right valve 76 on the ventilation passage connected to the exhaust port 83 of the gas storage chamber 82 prevents the compressed air in the gas storage chamber 82 from prematurely entering the ventilation passage connected to the air inlet 84 of the combustion chamber 86, thereby opening the left valve 75 and causing a leakage effect. Furthermore, after the working stroke of the compressed air entering the gas storage chamber 82 is completed, the air inlet 81 of the gas storage chamber 82 is closed by the one-way valve 80, preventing the compressed air in the gas storage chamber 82 from flowing back to the distributor 10. Furthermore, next, the left push rod 71 and right push rod 72, as well as the left rocker arm 73 and right rocker arm 74 outside each power cylinder, driven by their respective timing cams, push the thrust valve 77, left valve 75, and right valve 76 on the thrust burner, opening the outlet 83 of the air storage chamber 82 and the inlet 84 of the combustion chamber 86, thus pushing compressed air into the combustion chamber 86. Simultaneously, the NR section of the far-end arc surface of the flat sector-shaped rotary piston in each power cylinder, from point N 50 to point R 51, precisely seals the compound cylindrical inlet 29 of the cylinder and the outlet 89 of the combustion chamber 86, ensuring that the compressed air in the combustion chamber 86 does not leak or depressurize for a short period, facilitating mixing and combustion with the fuel. Furthermore, after the left valve 75 and right valve 76 reset and close the intake passage 84 above the combustion chamber 86, the thrust valve 77 resets, the fuel injector 90 injects fuel into the combustion chamber 86 to form a combustible mixture, the spark plug 91 releases a spark, and the fuel burns to produce high-temperature, high-pressure gas. At this time, the far-stopping arc surface R-point 50 of the flat sector-shaped piston in each power cylinder rotates away from the compound cylindrical intake port 29 of the cylinder, opening the compound cylindrical intake port 29 of the cylinder and the exhaust port 89 of the combustion chamber 86. The high-temperature, high-pressure gas simultaneously rushes towards the flat sector-shaped piston and the baffle plate. Since the high-temperature, high-pressure gas cannot push the baffle plate, and the baffle plate has good sealing properties, the high-temperature, high-pressure gas in each power cylinder pushes the flat sector-shaped piston inside, driving the main shaft 20 and flywheel 18 to rotate and perform work. As the flat sector-shaped piston, main shaft, and flywheel rotate, the temperature and pressure of the high-temperature, high-pressure gas gradually decrease.After the flat sector-shaped pistons in each working cylinder rotate past the compound cylindrical outlet 35 of the cylinder, the cooled and depressurized high-temperature and high-pressure gas discharged from the compound cylindrical outlets of the first working cylinder 6 and the second working cylinder 7 enters the left auxiliary cylinder 8 through the inlet 29, further applying a thrust to the flat sector-shaped piston 21 in the left auxiliary cylinder 8; the cooled and depressurized high-temperature and high-pressure gas discharged from the compound cylindrical outlets of the third working cylinder 12 and the fourth working cylinder 13 enters the right auxiliary cylinder 11, further applying a thrust to the flat sector-shaped piston 21 in the right auxiliary cylinder 11. Finally, the cooled and depressurized gas discharged from the left auxiliary cylinder 8 and the right auxiliary cylinder 11 has decreased to waste gas. The waste gas discharged from the outlet of the right auxiliary cylinder 11 enters the right air inlet 111 of the flue gas collection and filter duct 116; the waste gas discharged from the outlet of the left auxiliary cylinder 8 enters the left air inlet 118 of the flue gas collection and filter duct 116. The two streams of waste gas merge into one gas in the first filter chamber 112 of the flue gas collection and filter duct 116, and then continuously pass through the second filter chamber 113, the third filter chamber 114, and the fourth filter chamber 125, before being discharged into the atmosphere. The residual oil droplets in the waste gas flow back into the oil pan through the oil return pipe 124, and the particulate matter in the waste gas settles and accumulates in the three sedimentation cups: the right sedimentation cup 115, the left sedimentation cup 119, and the middle sedimentation cup 121, which are periodically removed by unscrewing the cleaning bolt 117.

[0109] In this invention, the cooling water inlet, outlet, and water channel include a cylindrical inlet 26, a cylindrical outlet 27, a water pump 22, a water tank 14, a cylindrical cooling water chamber 30, an end cap cooling water chamber 38, an end cap cooling water inlet pipe 39, an end cap cooling water outlet pipe 40, a thrust burner inlet pipe 85, a thrust burner outlet pipe 87, a thrust burner water channel 88, a base inlet pipe 100, a base cooling water channel 102, and a base outlet pipe 104. All of these are used for the circulation of cooling water in the engine to achieve the function of cooling and reducing temperature. This ensures that the engine of this invention will not stop due to high temperature caused by continuous combustion of fuel in the power cylinder during operation.

[0110] The engine housing of this invention also includes, inside or outside, a fuel supply system, an air supply system, an energy storage flywheel, a lubrication system, a battery ignition system, a cooling water circulation system, and a speed governor system. These technologies are currently publicly available and mature. The power cylinders in this invention can also be two, six, eight, or ten; these are technical solutions that can be easily conceived without much mental effort. Therefore, specific embodiments of this invention need not be listed one by one.

[0111] Detailed Implementation Method 2

[0112] Referring to Figure 43, in the low-power version of the engine device of the present invention, in order to meet the technical characteristics of simple structure, low power, light weight, and low cost of low-power engine devices, the left auxiliary cylinder 8 and its internal flat sector-shaped piston are replaced by a left counterweight block 143, and the right auxiliary cylinder 11 and its internal flat sector-shaped piston are replaced by a right counterweight block 144. Both the left and right counterweight blocks 143 and 144 are mounted on the main shaft with flat keys, and their phases are the same as the phases of the flat sector-shaped pistons in the auxiliary cylinders they replace. During operation, the centrifugal force of the left and right counterweight blocks 143 and 144 during rotation cancels out the centrifugal force of the flat sector-shaped pistons in the compression cylinders. The gas discharged from the first working cylinder 6, the second working cylinder 7, the third working cylinder 12, and the fourth working cylinder 13 directly enters the filter chimney 116 and is discharged after filtration. Through the above technical measures, the structure of the engine of the present invention is made simpler, the weight of the engine body is reduced, and the cost is reduced, ensuring that the engine device of the present invention can be applied to the technical features of low-power models.

Although the specifications and dimensions of the flat sector-shaped rotary plug (21), baffle base (95), and baffle (28) installed in each of the cylinders are not exactly the same, their structural shapes are the same. The baffle base (95) is installed in the baffle slot (36) of the composite cylinder of the corresponding cylinder. The baffle base (95) is provided with a base water inlet (100), a base water outlet (104), and a base cooling water channel (102) for cooling. The baffle base (95) is provided with a base oil inlet (101), a base oil outlet (103), a base front sealing door (106), and a base rear sealing door (105). The base front sealing door (106) and the base rear sealing door (105) have the same shape, specifications, and dimensions. The front sealing door (106) and the rear sealing door (105) are always pressed tightly against the front and rear surfaces of the baffle (28) to ensure the sealing of the baffle (28) on the front and rear surfaces during operation. The baffle plate (28) is installed inside the baffle plate base (95). A spring is installed inside the baffle plate base (95). The baffle plate (28) is pressed tightly against the flat fan-shaped rotary plug (21) inside the composite cylinder by the spring pressure. The baffle plate (28) is fixedly composed of two parts: a round handle (133) and a long plate (134). It has left and right sealing plates on both sides of the long plate, a long plate oil hole (136) in the middle of the long plate, and a sloping arc surface (135) at the bottom of the long plate. The sloping arc surface (135) is used to ensure that the baffle plate (28) can move up and down flexibly when pushed by the pushing arc surface of the flat fan-shaped rotary plug (21), and to make the baffle plate (28) is tightly fitted with the flat fan-shaped rotary plug (21) to prevent air leakage. The left and right sealing plates on both sides of the baffle plate (28) have the same structure and shape as the sealing plates on the flat fan-shaped rotary plug (21). The oil inside the baffle plate base (95) can enter the oil hole (136) of the long plate of the baffle plate (28). The front sealing door (106), the rear sealing door (105) and the left and right sealing plates of the baffle plate (28) in the baffle plate base (95) can tightly fit with the inner wall of the baffle plate base and slide up and down, which can effectively prevent the high pressure gas in the composite cylinder from leaking from the baffle plate slot (36). The profile of the flat fan-shaped rotary piston (21) is a fan-shaped structure. From point M (49) to point N (50) in the clockwise direction is the MN segment of the pushing arc face of the flat fan-shaped rotary piston (21). From point N (50) to point R (51) is the NR segment of the far-stopping arc face of the flat fan-shaped rotary piston (21). From point R (51) to point Y (52) is the RY segment of the playing arc face of the flat fan-shaped rotary piston (21). From point Y (52) to point M (49) is the YM segment of the near-stopping arc face of the flat fan-shaped rotary piston (21). The NR segment of the far-stopping arc face of the flat fan-shaped rotary piston (21) is... The radius of curvature of the arc surface is equal to the radius of curvature of the inner cavity of the composite cylinder. The length of the far-stopping arc surface NR section of the flat fan-shaped rotary plug (21) is set to be four times the diameter of the air inlet (29) on the composite cylinder of the working cylinder. With this technical feature, it is ensured that the far-stopping arc surface NR section of the flat fan-shaped rotary plug (21) can dynamically seal the air inlet (29) of the composite cylinder for a short period of time during each rotation of the air inlet (29) of the composite cylinder, so as to facilitate the compressed air entering the combustion chamber (86) without leakage or pressure reduction and fully mixing and burning with fuel in a short period of time. The flat sector-shaped rotary plug (21) is provided with a shaft hole (48), a keyway (45), an oil hole (46) on the far-stopping arc face, and an oil hole (47) on the side face. The keyway (45) is used to fix the position of the flat sector-shaped rotary plug (21) on the main shaft (20). The oil hole (46) on the far-stopping arc face and the oil hole (47) on the side face are connected to the radial oil hole on the main shaft (20) to ensure that the flat sector-shaped rotary plug (21) can be lubricated with oil when working. The flat sector-shaped rotary plug (21) has two rows of sealing plates installed on both sides. Each row of sealing plates consists of a left sealing plate (44) and a right sealing plate (43). The left sealing plate (44) has a left notch (53) at its outer end, and the right sealing plate (43) has a right notch (54) at its outer end. 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 has a small oil hole to facilitate the sealing plate to be lubricated by oil. Springs are also installed in the grooves. The springs cause the two rows of sealing plates to press tightly against the surface of the contacting parts after the flat sector-shaped rotary plug (21) is installed in the working cylinder, so as to ensure that the flat sector-shaped rotary plug (21) has good sealing performance after being installed in the working cylinder. The flat sector-shaped rotary plug (21) is installed inside the composite cylinder of the cylinder. The two sides and the far-stopping arc surface of the flat sector-shaped rotary plug are closely fitted with the left end cap and right end cap installed inside the composite cylinder and the inner wall curved surface of the composite cylinder, respectively. It can rotate flexibly. When the flat sector-shaped rotary plug (21) rotates inside the composite cylinder (25), during the process of mutual contact and pushing with the baffle plate (28), the MN section of the pushing arc surface of the flat sector-shaped rotary plug (21) pushes the baffle 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-shaped rotary plug (21). After the flat sector-shaped rotary plug (21) passes through, the baffle plate (28) falls back under the spring pressure. During the rotation of the flat sector-shaped rotary piston (21) inside the composite cylinder (25), the flat sector-shaped rotary piston (21) and the baffle plate (28) always divide the inner cavity of the composite cylinder (25) into two different types of states: one type is that the cylinder inlet (29) and cylinder outlet (35) of the composite cylinder (25) are not connected, and the other type is that the cylinder inlet (29) and cylinder outlet (35) of the composite cylinder (25) are connected to each other. These two states occur in a cyclical manner, so that the intake and compression strokes of the flat sector-shaped rotary piston (21) in the compression cylinder and the work and exhaust strokes of the flat sector-shaped rotary piston (21) in the power cylinder of the present invention are synchronized. Continuing along the rotation direction of the flat sector-shaped rotary plug (21): (i) When the baffle plate (28) and sector-shaped rotary plug (21) inside the composite cylinder (25) of the compression cylinder (9) are not connected to the cylinder inlet (29) and cylinder outlet (35), the compression cylinder (9) simultaneously draws air from the cylinder inlet (29) and pressurizes air from the cylinder outlet (35) into the gas distributor (10). When the cylinder inlet (29) and cylinder outlet (35) of the compression cylinder (9) are connected, the flat sector-shaped rotary plug (21) ends the air intake and compression stroke of the compression cylinder (9). (ii) When the baffle plate (28) and sector-shaped rotary plug (21) inside the composite cylinder (25) of the power cylinder are connected to the cylinder inlet (29) and cylinder outlet (35), the compression cylinder (9) continues to rotate. 21) When the cylindrical inlet (29) and cylindrical outlet (35) are not connected, the high-pressure gas from the combustion chamber (86) rushes from the cylindrical inlet (29) of the compound cylinder (25) of the power cylinder into the cavity between the flat sector-shaped rotary plug (21) and the baffle plate (28). The flat sector-shaped rotary plug (21) is driven by the high-pressure gas to rotate and perform work. At the same time, the flat sector-shaped rotary plug (21) also sweeps out the waste gas along the way to the cylindrical outlet (35). When the cylindrical inlet (29) and cylindrical outlet (35) are connected, the high-pressure gas inside the compound cylinder (25) of the power cylinder is discharged from the cylindrical outlet (35). The flat sector-shaped rotary plug (21) in the power cylinder performs work and discharges waste gas. When the working stroke ends, (iii) the working stroke of the baffle plate and the flat sector-shaped piston in the composite cylinder of the two auxiliary cylinders is connected to the working stroke of the baffle plate and the sector-shaped piston in the composite cylinder of the power cylinder. When the flat sector-shaped piston (21) of the composite cylinder of the power cylinder finishes rotating and exhausting, the cylinder inlet (29) in the auxiliary cylinder is connected to the gas discharged from the cylinder outlet (35), which continues to drive the flat sector-shaped piston (21) in the auxiliary cylinder to rotate and work. When the flat sector-shaped piston (21) of the composite cylinder of the power cylinder starts rotating and exhausting again, the rotation working stroke of the flat sector-shaped piston (21) in the auxiliary cylinder ends, and only the exhaust stroke follows. The engine of the present invention has only one cylindrical main shaft (20). The main shaft (20) passes through the left end cover bushing and right end cover bushing (139) and the shaft hole (48) of the flat sector-shaped piston in the composite cylinder of each cylinder, including all the power cylinders, auxiliary cylinders, and compression cylinders. The flat sector-shaped pistons (21) in each cylinder, which are connected in series on the main shaft (20), are each fixedly mounted on the main shaft (20) with a flat key. The timing cams of each thrust burner (5) are fixedly mounted on the main shaft with a flat key. On the shaft (20), the push rod and rocker arm outside the power cylinder are provided with thrust at regular intervals. The flywheel (18) and pulley (24) are also installed on the main shaft (20). Finally, the front end and the rear end of the main shaft (20) pass through the housing bushing (139) and are installed on the housing (15) of the engine of the present invention. The housing bushing (139) has an oil hole that is connected to the oil passage (55) on the central axis of the main shaft (20). Thus, all the cylinders of the present invention and the accessories installed inside and outside the cylinders are connected in series and installed as one unit by using a cylindrical main shaft (20). The main shaft (20) is provided with a central axis oil passage (55) and radial oil holes (56) so as to connect with the oil holes of each flat fan-shaped piston; The phase relationship between the power cylinder, auxiliary cylinder and compression cylinder installed in series on the main rotating shaft (20) in the apparent plane is as follows: with a compression cylinder (9) as the center, the specific situation of the cylinders installed on the left and right sides of it, in order from left to right, is: first power cylinder (6), second power cylinder (7), left auxiliary cylinder (8), compression cylinder (9), right auxiliary cylinder (11), third power cylinder (12), and fourth power cylinder (13); The phase relationship between the flat sector-shaped pistons (21) in each cylinder, which are installed in series on the main shaft (20), on the apparent plane is as follows: the far-stop arc surface (57) of the flat sector-shaped piston profile in the first working cylinder (6) is upward; the far-stop arc surface (59) of the flat sector-shaped piston profile in the second working cylinder (7) is downward; the far-stop arc surface (67) of the flat sector-shaped piston profile in the left auxiliary cylinder (8) is downward; the far-stop arc surface (65) of the flat sector-shaped piston profile in the compression cylinder (9) is upward; and the far-stop arc surface of the flat sector-shaped piston profile in the right auxiliary cylinder (11) is... The technical features of this layout, with the flat sector piston (21) in the third power cylinder (12) facing downwards, the far-stopping arc surface of the flat sector piston in the fourth power cylinder (13) facing upwards, ensure that the centrifugal forces of the flat sector piston (21) in the four power cylinders cancel each other out during rotation; and ensure that the centrifugal force of the flat sector piston in the compression cylinder (9) cancels out the centrifugal force between the flat sector piston in the left auxiliary cylinder (8) and the flat sector piston in the right auxiliary cylinder (11), thereby reducing the intensity of engine vibration. When the engine device of the present invention is working, the flat sector-shaped pistons in the four power cylinders, the flat sector-shaped pistons in the compression cylinder (9), and the flat sector-shaped pistons in the two auxiliary cylinders rotate synchronously on the same main shaft (20). The flat sector-shaped piston (21) in the compression cylinder (9) draws air into the compression cylinder (9) through the air inlet (29) and compresses the air into the gas distributor (10) at the same time. The gas distributor (10) inputs the compressed air into the gas storage chamber (82) of the thrust burner on each power cylinder through the four single ports (142) of the two left and right "Y" shaped air outlet pipes (107). At this time, the thrust valve (77) and the left valve (75) of each thrust burner are activated. With the right valve (76) stationary, the ventilation passage between the outlet (83) of the air reservoir (82) and the inlet (84) of the combustion chamber (86) is closed. The sealing effect of the right valve (76) on the ventilation passage connected to the outlet (83) of the air reservoir (82) prevents the compressed air in the air reservoir (82) from prematurely entering the ventilation passage connected to the inlet (84) of the combustion chamber (86), thereby opening the left valve (75) and causing a leakage effect. After the working stroke of the compressed air entering the air reservoir (82) is completed, the inlet (81) of the air reservoir (82) is closed by the one-way valve (80), preventing the compressed air in the air reservoir (82) from flowing back to the distributor (10). Furthermore, each working... The left push rod (71) and right push rod (72) outside the cylinder, as well as the left rocker arm (73) and right rocker arm (74), under the push of their respective timing cams, push the left valve (75), right valve (76), and push valve (77) on the thrust burner, opening the outlet (83) of the gas storage chamber (82) and the inlet (84) of the combustion chamber (86), pushing compressed air into the combustion chamber (86). At the same time, the NR segment of the arc surface from point N (50) to point R (51) of the far-end arc surface of the flat sector piston in each working cylinder just closes the compound cylindrical inlet (29) of the cylinder and the outlet (89) of the combustion chamber (86). Furthermore, when the left valve (75) and right valve (76) reset and close, After the intake passage (84) above the combustion chamber (86) is closed, the thrust valve (77) resets. Then, the fuel injector (90) injects fuel into the combustion chamber (86) to form a combustible mixture. The spark plug (91) releases a spark, and the fuel burns to produce high-temperature and high-pressure gas. At this time, the far-stopping arc surface R point (50) of the flat sector-shaped rotary piston in each power cylinder just rotates away from the compound cylindrical air inlet (29) of the cylinder, opening the compound cylindrical air inlet (29) of the cylinder and the air outlet (89) of the combustion chamber (86). The high-temperature and high-pressure gas rushes towards the flat sector-shaped rotary piston (21) and the baffle plate (28) at the same time. Since the high-temperature and high-pressure gas cannot push the baffle plate (28), and the baffle plate (28) has good sealing properties,Therefore, the high-temperature and high-pressure gas in each working cylinder drives the flat sector-shaped piston (21) inside to drive the main shaft (20) and flywheel (18) to rotate and perform work. As the flat sector-shaped piston (21), the main shaft (20) and flywheel (18) rotate, the temperature and pressure of the high-temperature and high-pressure gas gradually decrease. After the flat sector-shaped piston (21) in each working cylinder rotates past the compound cylinder outlet (35) of the cylinder, further, gas is discharged from the compound cylinders of the first working cylinder (6) and the second working cylinder (7). The high-temperature and high-pressure gas discharged from the outlet (35) after cooling and depressurization enters the left auxiliary cylinder (8) through the cylindrical air inlet (29) of the left auxiliary cylinder (8), further exerting a thrust on the flat sector-shaped rotary piston (21) inside the left auxiliary cylinder (8); the high-temperature and high-pressure gas discharged from the composite cylindrical air outlet (35) of the third working cylinder (12) and the fourth working cylinder (13) after cooling and depressurization enters the right auxiliary cylinder (11) and further exerts a thrust on the flat sector-shaped rotary piston (21) inside the right auxiliary cylinder (11). Finally, the cooled and depressurized gas discharged from the left auxiliary cylinder (8) and the right auxiliary cylinder (11) has become waste gas. The waste gas discharged from the outlet of the right auxiliary cylinder (11) enters the right air inlet (111) of the filter chimney (116); the waste gas discharged from the outlet of the left auxiliary cylinder (8) enters the left air inlet (118) of the filter chimney (116). The two waste gases merge into one gas in the first filter chamber (112) of the filter chimney (116), and continuously pass through the second filter chamber (113), the third filter chamber (114), the fourth filter chamber (125), and the exhaust port (126), and then are discharged into the atmosphere. Residual oil droplets in the waste gas flow back into the oil pan (141) through the return oil pipe (124). Particulate matter in the waste gas settles and accumulates in three sedimentation cups: the right sedimentation cup (115), the left sedimentation cup (119), and the middle sedimentation cup (121). These are periodically removed by unscrewing the cleaning bolt (117).

2. The integrated engine with a single cylindrical main shaft as described in claim 1, characterized in that, The thrust valve (77) consists of a small-diameter disc (131) mounted on the upper end of a cylinder (130) and a large-diameter disc (132) mounted on the lower end. The cylinder has threads at both ends and threaded holes in the center of the two discs. The cylinder and the two discs are tightened together by screws. The cylinder (130) has a central oil passage (97). The large-diameter disc (132) has three sealing spring rings (98). The three sealing spring rings (98) are installed in the annular groove. The annular groove has radial holes that communicate with the central oil passage (97). The outer diameter surface of the cylinder has a through-hole (137) that communicates with the central oil passage (97).

3. The integrated engine with a single cylindrical main shaft as described in claim 1, characterized in that, The filter stack (116) is equipped with a right air inlet (111), a left air inlet (118), a first filter chamber (112), a second filter chamber (113), a third filter chamber (114), a fourth filter chamber (125), a right sedimentation cup (115), a left sedimentation cup (119), a middle sedimentation cup (121), a filter cup (123), a return oil pipe (124), a slag removal bolt (117), a left self-starting valve (120), a right self-starting valve (122), and an exhaust port (126). When the engine is running, the exhaust gas flows from the right auxiliary cylinder (11... The waste gas discharged from the exhaust port enters the right air inlet (111) of the filter chimney (116), and the waste gas discharged from the exhaust port of the left auxiliary cylinder (8) enters the left air inlet (118) of the filter chimney (116). The two streams of waste gas merge into one gas in the first filter chamber (112), and then turn and enter the second filter chamber (113), the third filter chamber (114), and the fourth filter chamber (125), and then are discharged into the atmosphere. During this process, residual oil droplets and tiny particles in the waste gas bend and collide with the filter chamber wall as the airflow passes through. This results in sediment accumulation in the three cups: the right sediment collection cup (115), the left sediment collection cup (119), and the middle sediment collection cup (121). The left self-opening valve (120) and the right self-opening valve (122) have the same structure; both are designed to close under pressure from flowing waste gas and automatically open when the engine is off and there is no flowing waste gas pressure, relying on spring force. The left self-opening valve (120) and the right self-opening valve (122) are closed when the engine is running and open when the engine is off. This causes sediment to accumulate in the right sediment collection cup (115), the left sediment collection cup (119), and the middle sediment collection cup (121). The residual oil droplets that settle and accumulate in the three cups (119, 121, and 123) flow to the filter cup (123) when the engine is stopped. The residual oil filtered by the filter cup (123) flows back into the oil pan through the return oil pipe (124). When the engine is running, since the left and right automatic start valves are closed, the exhaust gas flowing through the filter chimney (116) will not enter the oil pan 141. The particulate matter in the three sediment cups is periodically removed by unscrewing the cleaning bolt (117).

The integrated engine with a single cylindrical main shaft as described in claim 1, characterized in that, In the low-power version of the engine device of the present invention, in order to be suitable for the technical characteristics of simple structure, low power, light weight and low cost of low-power engine devices, the left auxiliary cylinder (8) and its internal flat sector piston in the engine device of the present invention are replaced by a left counterweight block (143), and the right auxiliary cylinder (11) and its internal flat sector piston are replaced by a right counterweight block (144). The left counterweight block (143) and the right counterweight block (144) are both mounted on the main rotating shaft (20) with flat keys, and their respective phases are the same as the phases of the flat sector pistons in the auxiliary cylinders they replace.
