Description

Technical Field

[0001] The invention relates to the field of fuel and gas engines, and in particular to a rotary engine. Background Art

[0002] As we all know, current engines are usually piston engines. Piston engines usually use gasoline and air mixed, burned in a closed container (cylinder), expanded to do work, pushed the piston downward to drive the crankshaft to rotate, converted into rotational kinetic energy, and output power in this form. Piston engines are traditional four-stroke reciprocating piston engines. When the engine rotates twice, each cylinder completes the intake, compression, ignition and exhaust process once, and the work is relatively inefficient; and there are many parts and auxiliary equipment (water cooling, starter motor and turbocharged engine, etc.). Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] In order to overcome the problem of low working efficiency of existing engines, the present invention provides a rotary engine.

[0005] (II) Technical solution

[0006] In order to solve the above technical problems, the present invention provides a rotary engine, which includes a cylinder, a fuel injector, a spark plug, at least one first gear and at least one second gear; the first gear and the second gear are installed in the cylinder and can rotate freely, and the gear shafts of the first gear and the second gear parallel to each other are at least partially power output shafts, and the first gear and the second gear rotate with each other;

[0007] The first gear and the second gear each include a tooth root and a plurality of tooth structures, wherein the tooth structures are mounted on the tooth root and distributed around the tooth root; the tooth structure includes: a tooth shank and a leaf-shaped tooth head, wherein a first end of the tooth shank is connected to the tooth root, and a second end is connected to a blade root portion of the leaf-shaped tooth head;

[0008] Between the front end and the rear end of the cylinder body, each of the plurality of leaf-shaped tooth heads of the tooth structure of the first gear, two adjacent tooth structures and tooth roots of the second gear, and the inner wall of the cylinder body form a semi-enclosed rotary combustion chamber;

[0009] When the first gear and the second gear are rotating, each lobe-shaped tooth head of the first gear respectively interlocks with two adjacent lobe-shaped tooth heads of the second gear, thereby closing the opening of the semi-closed rotating combustion chamber, so that the semi-closed rotating combustion chamber is continuously closed and opened during rotation.

[0010] (III) Beneficial effects

[0011] The tooth head structures of the first gear and the second gear used in the present invention are both blade tooth heads. When the two blade tooth heads are aligned, the closed space is larger than the space of the tooth heads of ordinary gears, and the space can be used as a combustion chamber. The first gear and the second gear are installed in the cylinder body, and the first gear and the second gear rotate relatively. The blade-shaped tooth heads are aligned, and each of the multiple blade-shaped tooth heads of the first gear tooth structure and the two adjacent tooth structures and tooth roots of the second gear and the inner wall of the cylinder body form a semi-enclosed rotating combustion chamber, and the tooth and space are relatively closed, and as the blade tooth heads are aligned, the space changes from large to small and then from small to large.

[0012] The relatively sealed space is the same as the space where the piston inside the traditional fuel engine works. When the lobe-shaped gear head of the first gear is just sealed with the lobe-shaped gear head of the second gear, the fuel spray or combustion gas can be sprayed into this closed space by the fuel nozzle. Due to the mutual rotation of the gears, the closed space is compressed to the minimum space. The lobe-shaped gear head of the first gear is inserted into the closed space between the two lobe-shaped gear heads of the second gear like a piston. After turning the minimum space, the space changes from small to large. At this time, the compressed fuel spray or combustion gas in the closed space can be ignited by the spark plug, so that the compressed mixed gas formed by the fuel mist or combustion gas and air explodes and burns, and the expanding gas pushes the two teeth and rotating lobe-shaped gears to accelerate the reverse rotation. As the gear rotates, the different combustion chambers of the gear turn to the teeth and are closed. Then it enters the next rotating combustion chamber that inhales new air and is closed. The gas in the next rotating combustion chamber burns, and the gas expands, which pushes the gear to rotate again. By analogy, the multiple combustion chambers of the rotary engine work multiple times in one circle in turn, and the fuel thermal efficiency is high and the power output is greater than the power output of the traditional piston. Moreover, two gears are arranged in the cylinder body, and a fuel injection nozzle and a spark plug are arranged in the cylinder body, so the overall structure is simple and has fewer parts.

[0013] As the gears rotate, the combustion chamber after ignition rotates to another angle to discharge high-pressure gas, rotates a certain angle to inhale new air, and then rotates a certain angle to be closed again to do work again. One tooth and space rotates one circle to complete the four processes of intake-compression-work-exhaust that a piston engine needs to rotate two circles to complete.

[0014] Theoretically, the number of teeth on a gear is the number of times the combustion chamber does work during one rotation. Gears can have multiple teeth, such as four, five, six, or countless teeth. The more teeth there are, the lower the space compression ratio. At the same time, when the number of teeth increases, the combustion chamber space is smaller for the same diameter, and the time to do work during rotation is shorter.

[0015] In addition, when there are multiple first gears and second gears, multiple first gears can share the first gear shaft, and multiple second gears can share the second gear shaft, forming multiple first gears and second gear teeth and a combined structure that are parallel to each other up and down, providing power more efficiently.

[0016] Alternatively, when there are multiple first gears and second gears, multiple groups of first gears and second gears form a combined structure, and the multiple combined structures are connected in parallel and / or in series. The high-pressure combustion gas between two adjacent combined structures is connected through a pipeline, which can not only delay the unburned discharge of the high-pressure combustion gas but also make full use of the kinetic energy of the gas, making the combustion efficiency more efficient.

[0049] First embodiment

[0050] Combine the following Figure 1 and Figure 2 The working principle diagram and structure diagram illustrate the four-tooth single rotating combustion chamber rotor engine composed of a pair of four-tooth multi-lobed gears in an embodiment of the present invention.

[0051] Figure 1 The third figure is a schematic diagram of a pair of identical four-toothed lobe gears with different positions in rotation. The lobe-shaped rotary piston head gear 1 (also called the first gear, named as the lobe-shaped rotary piston head gear because it acts as a piston head) rotates counterclockwise around its gear shaft, and the lobe-shaped rotary combustion chamber gear 2 (also called the second gear, named as the lobe-shaped rotary combustion chamber gear because it acts as a combustion chamber) rotates clockwise around its gear shaft. The gear shafts of the two gears are parallel and have the same tooth width. Both gears include a tooth root and a plurality of tooth structures, which are mounted on the tooth root and distributed around the tooth root; the tooth structure includes: a tooth handle and a lobe-shaped tooth head, the first end of the tooth handle is connected to the tooth root, and the second end is connected to the root of the lobe-shaped tooth head; the edge of the lobe-shaped tooth head. That is, both gears are composed of a lobe-shaped tooth head with four teeth, a tooth root, a tooth handle connecting the lobe-shaped tooth head and the tooth root, and a gear shaft. The installation connection between the first gear and the gear shaft of the first gear and the second gear and the gear shaft of the second gear can be a fixed integral rotation installation or a ratchet rotation installation.

[0052] It should be noted that in some other embodiments, the number of teeth of the first gear generating the tooth sum and the number of teeth of the second gear may be inconsistent. In some other embodiments, the tooth top circle diameter of the first gear generating the tooth sum and the tooth top circle diameter of the second gear may be inconsistent.

[0053] On the lobe-shaped rotary combustion chamber gear 2, the blade tooth heads, tooth shanks and tooth roots of two adjacent tooth structures form a rotary combustion chamber 3. The lobe-shaped rotary combustion chamber gear includes four such combustion chambers: No. 1 combustion chamber 8, No. 2 combustion chamber, No. 3 combustion chamber, and No. 4 combustion chamber. The lobe-shaped rotary piston head gear 1 includes four lobe-shaped tooth heads, namely, No. 1 tooth, No. 2 tooth, No. 3 tooth, and No. 4 tooth. When the gear rotates, the four tooth heads of the lobe-shaped rotary piston head gear 1 respectively and sequentially close and open the four combustion chamber spaces of the lobe-shaped rotary combustion chamber gear 2. Figure 1 The three sub-figures from top to bottom respectively indicate the different states of the lobe-shaped rotating piston head gear 1 and the lobe-shaped rotating combustion chamber gear 2 in the process of rotating from tooth harmony to separation. In the first state figure, the lobe-shaped tooth head of the lobe-shaped rotating piston head gear 1 has just rotated to the tooth harmony position with the two lobe-shaped tooth heads of combustion chamber No. 1 8, so that a sealed area is formed in combustion chamber No. 1 8. At this time, the space of combustion chamber No. 1 8 is the largest. When it rotates to the second state position, the tooth harmony of combustion chamber No. 1 8 is inserted and compressed to the minimum compression ratio of nearly 3:1 by the rotation of the lobe-shaped rotating piston head gear 1. When it reaches the third state position, the closed space of combustion chamber No. 1 8 reaches the maximum and the sealed state is changed to an open state.

[0054] from Figure 1 As shown in the three state diagrams, when the lobe-shaped rotating piston head gear 1 and the lobe-shaped rotating combustion chamber gear 2 are placed in the cylinder body, especially after the two ends of the lobe-shaped rotating combustion chamber gear 2 are relatively closed by the inner wall of the cylinder body, when the teeth are aligned, the rotating combustion chamber 3 will become a closed space. Specifically, combustion chamber No. 1 8 in the figure becomes a closed rotating combustion chamber 3, and the lobe-shaped rotating piston head gear 1 is like the piston head of a traditional air chamber, and the rotating combustion chamber 3 of the lobe-shaped rotating combustion chamber gear 2 is like a traditional piston air chamber, completing the process of gas compression, igniting the mixed combustion gas, and then exploding and burning to drive the gear to rotate and do work.

[0055] from Figure 2 As can be seen from the structural diagram, the lobe-shaped rotary piston head gear 1 is installed on the lobe-shaped rotary piston head gear shaft 21, the lobe-shaped rotary combustion chamber gear 2 is installed on the rotary combustion chamber shaft 22, and the lobe-shaped rotary piston head gear shaft 21 and the rotary combustion chamber shaft 22 are arranged in parallel.

[0056] The leaf-shaped rotating piston head gear 1 and the leaf-shaped rotating combustion chamber gear 2 are exactly the same four-tooth leaf-shaped gears. The leaf-shaped rotating piston head gear 1 and the leaf-shaped rotating combustion chamber gear 2 are sandwiched between the front cylinder side plate 11 and the rear cylinder side plate 12. The front cylinder side plate 11 and the rear cylinder side plate 12 are respectively provided with a leaf-shaped rotating piston head gear shaft hole 64 and a rotating combustion chamber shaft hole 65, so that the leaf-shaped rotating piston head gear shaft 21 and the rotating combustion chamber shaft 22 can pass through the holes. The leaf-shaped rotating piston head gear 1 and the leaf-shaped rotating combustion chamber gear 2 can be tightly attached to the inner wall teeth of the front cylinder side plate 11 and the rear cylinder side plate 12 and rotate, but do not contact the inner wall of the front cylinder side plate 11 and the rear cylinder side plate 12, and there is a gap.

[0057] In some embodiments, in order to form a stable cavity between the front cylinder side plate and the rear cylinder side plate and facilitate the installation of the lobe-shaped rotary piston head gear 1 and the lobe-shaped rotary combustion chamber gear 2, the front cylinder side plate 11 and the rear cylinder side plate 12 are separated by an intermediate spacer block 35. The intermediate spacer block 35 is slightly wider than the tooth width of the two four-tooth lobe gears to play a supporting role.

[0058] At the same time, oil ports 10 are respectively opened on the front cylinder side plate 11 and the rear cylinder side plate 12. The position of the oil port 10 does not exceed the height of the tooth roots of the two leaf-shaped gears. At the same time, a gear end surface oil shallow groove 9 (i.e., the oil groove mentioned above) is opened on the gear end surface 16 of the two leaf-shaped gears. When the two leaf-shaped gears rotate, the oil port 10 is connected to add oil. The centrifugal force allows the added oil to flow along the gear end surface oil shallow groove 9 to the tooth head, so that the tooth ends of the two leaf-shaped gears and the inner wall surfaces of the front cylinder side plate 11 and the rear cylinder side plate 12 are always separated by a thin oil film, which plays a lubricating role and also has the role of an oil seal, which can seal the high-pressure combustion gas in the rotating combustion chamber 3 from leaking from the two gear end surfaces through the two gear shafts.

[0059] Each rotary combustion chamber 3 in the lobe-shaped rotary combustion chamber gear 2 is equipped with at least one fuel injector 13 (of course, the multiple fuel injectors 13 here can also be cancelled, and the fuel injectors 13 are also installed on the two gear teeth and positions on the front cylinder side plate 11 or the rear cylinder side plate 12), and at least one spark plug 14 is installed on the two gear teeth and positions on the front cylinder side plate 11 or the rear cylinder side plate 12 for ignition. The operation of the fuel injectors 13 and the spark plugs 14 are controlled by the central electronic controller.

[0060] For example, four fuel injectors 13 are respectively installed at the four tooth roots of the lobe-shaped rotary combustion chamber gear 2, and the rotary combustion chamber shaft 22 is a hollow shaft. When the rotary combustion chamber shaft 22 rotates, oil is delivered to the four fuel injectors 13 through the fluid pipeline high-speed rotary joint 45 and the oil inlet pipe 47 installed at one end of the rotary combustion chamber shaft 22. At the same time, a high-speed rotating conductive slip ring 46 is also installed on the rotary combustion chamber shaft 22. The control signal sent by the central electronic controller of the engine controls the four fuel injectors 13 to spray oil through the high-speed rotating conductive slip ring 46. The oil inlet pipe and the fuel injector are directly connected or connected through a movable rotating structure.

[0061] from Figure 1 As can be seen from the second state diagram, a spark plug 14 is installed on the front cylinder side plate 11 (in other embodiments, it can also be installed on the rear cylinder side plate 12), and the fuel injection nozzle 13 in the No. 1 combustion chamber 8 sprays fuel mist; then the two gears rotate relative to each other to Figure 1 In the position shown in the second state diagram, the No. 1 combustion chamber 8 has been compressed to the minimum. At this time, the spark plug installed on the front cylinder side plate is ignited, and the compressed mixed gas formed by the fuel mist and air in the No. 1 combustion chamber 8 explodes and burns, pushing the two mutually toothed and rotating leaf-shaped gears to accelerate their rotation around their own gear shafts. These two gear shafts can be used as power output shafts separately or simultaneously; Figure 1 In the third state diagram, as the gear rotates, the teeth and the rotating leaf-shaped tooth heads rotate apart so that the high-pressure explosion gas is ejected from this opening to complete the work.

[0062] Figure 2 The figure shows that the tooth width of a pair of gears increases, and the corresponding combustion chamber space is also increased. The increase in tooth width makes the tooth and line 17 increase accordingly, and the force-bearing part of the gear increases, making the gear more wear-resistant, but the corresponding lengthening of the tooth and line 17 weakens the sealing performance. It should be noted that the tooth and line are the contact surface of the gear teeth when they are in a straight line, which is invisible in the actual product and keeps moving. The position indicated in the figure only indicates the tooth and line at a certain position.

[0063] from Figure 1 From the three position states, the gas combustion and expansion work process of the No. 1 combustion chamber 8 of the lobe-shaped rotary combustion chamber gear 2 is only completed in a part of the rotation angle in one rotation. Its rotation work process is different from the traditional piston engine which needs to rotate two circles to complete one work. The four processes of this rotary engine waste less energy and have a simple structure. At the same time, the No. 1 combustion chamber 8, No. 2 combustion chamber, No. 3 combustion chamber, and No. 4 combustion chamber of the lobe-shaped rotary combustion chamber gear 2 can be used as combustion chambers in sequence and continuously, and can continuously work four times in one rotation. Therefore, although the rotary engine of the present invention is small in size, it can also output a lot of power. Moreover, the four-leaf gear rotary combustion chamber structure also solves the problem that the traditional piston engine needs four processes to work once, has many parts and a complex structure.

[0064] On the other hand, the air is directly around the gears, which has the advantage of good exhaust heat dissipation. The gears can be in direct contact with the outside air, so they can dissipate heat very well, so that the blades and teeth of the gears do not need to work in a harsh environment (high pressure, high temperature and high tooth force) for a long time, thereby extending the service life of the gears. At the same time, the entire engine does not need to be installed with a heavy water cooling device, reducing the weight of the entire engine. The disadvantage is that the combustion gas does not have enough time to work due to the fast rotation speed, and the combustion gas in the rotating combustion chamber 3 is not fully burned and discharged into the air to pollute the environment, and the combustion thermal efficiency is not high.

[0065] On the other hand, the cavity wall of the cylinder body is provided with a high-pressure gas discharge channel of the lobe-shaped rotary piston head gear and a high-pressure gas discharge channel of the lobe-shaped rotary combustion chamber gear; the high-pressure gas discharge channel of the lobe-shaped rotary piston head gear is connected to the lobe-shaped rotary piston head gear; the high-pressure gas discharge channel of the lobe-shaped rotary combustion chamber gear is connected to the lobe-shaped rotary combustion chamber gear. The cavity wall of the cylinder body is provided with a cooling gas discharge channel of the lobe-shaped rotary piston head gear, a cooling gas intake channel of the lobe-shaped rotary piston head gear, a cooling discharge channel of the lobe-shaped rotary combustion chamber gear and a cooling intake channel of the lobe-shaped rotary combustion chamber gear; the cooling gas discharge channel in the lobe-shaped rotary piston head gear and the cooling gas intake channel in the lobe-shaped rotary piston head gear are connected to the lobe-shaped rotary piston head gear; the cooling gas discharge channel in the lobe-shaped rotary combustion chamber gear and the cooling gas intake channel in the lobe-shaped rotary combustion chamber gear are connected to the lobe-shaped rotary combustion chamber gear.

[0066] The several combustion chambers on the lobe-shaped rotary combustion chamber gear 2 work separately while cooling the exhaust passage and the cooling intake passage. The temperature of each blade tooth head of the lobe-shaped rotary combustion chamber is not high, and it only works once in one rotation. At the same time, after the combustion chamber 8 No. 1 has done work once, it can directly pass through the external natural space at other rotation positions in this circle, and can directly contact with the outside air, so it can dissipate heat well, so that the blade tooth head of the gear does not need to work in a harsh environment (high pressure, high temperature and high tooth force) for a long time, thereby extending the service life of the gear. At the same time, the entire engine does not need to install a heavy water cooling device, which reduces the weight of the entire engine.

[0067] Second embodiment

[0068] Combine the following Figure 3 , Figure 4 and Figure 5 The invention discloses a five-tooth single-rotating combustion chamber rotor engine composed of five-tooth blade gears.

[0069] Figure 3Two identical pairs of five-tooth leaf-shaped gears can be seen, the leaf-shaped rotary piston head gear 1 on the left, the leaf-shaped rotary combustion chamber gear 2 on the right, the rotary combustion chamber 3 composed of the rotary combustion chamber shaft 22, the rotary combustion chamber front circular clamp 23 and the rotary combustion chamber rear circular clamp 24, the diameter of the circular clamp is approximately the second tooth top circle diameter, and the approximation here means: the diameter of the circular clamp is greater than the second tooth top circle diameter, or the diameter of the circular clamp is equal to the second tooth top circle diameter, or the diameter of the circular clamp is slightly smaller than the second tooth top circle diameter. In some embodiments, the two circular clamps and the second gear can be manufactured separately and then installed as a whole as an integrated structure. In other embodiments, one of the two circular clamps can also be manufactured as an integral part with the second gear, and then installed as a whole as an integrated structure. The connection between the gear shaft of the second gear and the circular clamp can be fixedly installed to rotate as a whole, or a gear (including a ratchet) can be installed on the gear shaft, and then the gear is installed in the hole on the side plate of the cylinder body.

[0070] In different embodiments, the circular clamping plate can be solid or hollow. On the outside of the engine body, a fluid pipeline high-speed rotary joint 45, an oil inlet pipe 47 and a high-speed rotary conductive slip ring 46 are respectively installed at the head and vicinity of one end of the hollow rotary combustion chamber shaft 22, and a lobe-shaped rotary piston head gear 1 is installed on the lobe-shaped rotary piston head gear shaft 21. The lobe-shaped rotary piston head gear 1 and the lobe-shaped rotary combustion chamber gear 2 on the rotary combustion chamber 3 rotate with each other, and a high-speed rotary conductive slip ring 46 is also installed at one end of the lobe-shaped rotary piston head gear shaft 21. Spark plugs 14 are respectively installed on the five tooth head sides close to the lobe-shaped rotary piston head gear 1, and fuel injectors 13 are respectively installed at the five tooth roots of the lobe-shaped rotary combustion chamber gear 2 (the installation positions of the spark plugs 14 and the fuel injectors 13 are interchangeable. For this change, the lobe-shaped rotary piston head gear shaft 21 is a hollow structure, and the fluid pipeline high-speed rotary joint 45 and the oil inlet pipe 47 are loaded on the hollow lobe-shaped rotary piston head gear shaft 21). In some embodiments, the fuel injector 13 and the spark plug 14 can be installed on the circular clamping plate, and the fuel injector 13 and the spark plug 14 can be installed on the inner surface of the circular clamping plate or penetrate the two surfaces of the circular clamping plate. In other embodiments, the fuel injector 13 and the spark plug 14 can also be arranged on each leaf-shaped tooth head of the first gear, or each tooth structure or tooth root of the second gear.

[0071] like Figure 4 As shown, when the lobe-shaped rotating piston head gear 1 on the left and the lobe-shaped rotating combustion chamber gear 2 on the right have the same number of teeth and mesh with each other, the combustion chamber 8 of No. 1 completes the entire process of sealing, compression, fuel injection and combustion to seal opening, which is similar to the first embodiment. Figure 1 The working process of the four-toothed leaf gear is the same. Figure 4It can be seen that the engine composed of five-tooth gears has one more rotary combustion chamber than the engine composed of four-tooth gears. At the same time, the spatial compression ratio of the No. 1 combustion chamber 8 in the leaf-shaped rotary piston head gear 1 reaches nearly 2:1.

[0072] In order to better improve the problems of air leakage and local overheating that may damage the gears, the following improvements have been made to the engine composed of five-tooth blade gears:

[0073] like Figure 4 As shown, circular splints are included between the two ends of the lobe-shaped rotating combustion chamber gear 2 and the inner walls of the front cylinder side plate 11 and the rear cylinder side plate 12 of the cylinder body. Every two adjacent tooth structures of the lobe-shaped rotating combustion chamber gear 2 and the tooth roots and two circular splints form a semi-closed rotating combustion chamber 3; the circular splints at both ends and the lobe-shaped rotating combustion chamber gear 2 together form a rotating combustion chamber 3, and the rotating combustion chamber shaft 22 passes through and is fixedly connected to the rotating combustion chamber 3 so that it can rotate as a whole.

[0074] The lobe-shaped rotary combustion chamber gear 2 on the right and the circular clamps at both ends become an integrated rotating body to constitute a rotary combustion chamber 3. The diameter of the two circular clamps is approximately the same as the top circle diameter of the lobe-shaped rotary combustion chamber gear 2. The two circular clamps and the lobe-shaped rotary combustion chamber gear 2 can be formed into a whole by bolts or welding. There is only an opening between two adjacent lobe-shaped tooth heads of the lobe-shaped rotary combustion chamber gear 2, and the rest of the parts are sealed.

[0075] like Figure 3 As shown, the lobe-shaped rotary piston head gear 1 and the lobe-shaped rotary combustion chamber gear 2 rotate and mesh, closing the opening between the two lobe-shaped gear heads of the No. 1 combustion chamber 8. The five combustion chambers of the rotary combustion chamber 3 can be used as traditional piston air chambers. The five piston heads and the five piston air chambers respectively mesh so that the sealing-fuel injection-compression-work-exhaust-intake process is completed in the five air chambers respectively, just like the fuel engine composed of four-tooth lobe gears in the first embodiment, which can continuously work after one rotation.

[0076] like Figure 5 As shown, circular holes, i.e., rotating combustion chamber circular clamping plate hole holes 25, are respectively opened on the front cylinder side plate 11 and the rear cylinder side plate 12. The depth of the rotating combustion chamber circular clamping plate hole holes 25 is approximately equal to the thickness of the circular clamping plates constituting the rotating combustion chamber 3. The diameter of the circular holes is slightly larger than the diameter of the circular clamping plates. The front and rear circular clamping plates can be respectively embedded in the rotating combustion chamber circular clamping plate hole holes 25 on the front cylinder side plate 11 and the rear cylinder side plate 12 without contact and can rotate freely.

[0077] An oil port 10 is opened on the front cylinder side plate 11 and the rear cylinder side plate 12 near the root of the lobe-shaped rotary piston head gear 1 and the root of the lobe-shaped rotary combustion chamber gear 2 or the outer end surfaces of the front and rear circular splints, through which lubricating oil can be added to facilitate the high-speed rotation of the lobe-shaped rotary piston head gear 1 and the above-mentioned front and rear circular splints in the circular splint hole 25 of the rotary combustion chamber. Due to the centrifugal effect of rotation, the oil can be thrown at high speed to the gap between the outer edge of the front and rear circular splints and the circular hole, so that the high-pressure combustion gas is sealed by the oil at this gap and is not easily leaked.

[0078] In this embodiment, a leaf-shaped rotary piston head gear shaft hole 64 and a rotary combustion chamber shaft hole 65 are opened on the front cylinder side plate 11 and the rear cylinder side plate 12, and oil lubrication is added between the gear end face 16 of the above-mentioned leaf-shaped rotary piston head gear 1 and the two front cylinder side plates 11 and the rear cylinder side plates 12, as well as between the above-mentioned rotary combustion chamber circular clamping plate hole socket 25 and the circular clamping plate of the rotary combustion chamber 3, so that the leaf-shaped rotary piston head gear 1 sealed and clamped by the front cylinder side plate 11 and the rear cylinder side plate 12 and the leaf-shaped rotary combustion chamber gear 2 on the rotary combustion chamber 3 rotate with each other in the opposite direction; at the same time, due to the small gap in the refueling space and the oil pressure of the centrifugal rotation force, these gaps are sealed with oil to reduce the leakage of high-pressure combustion gas.

[0079] In this embodiment, if Figure 3 and Figure 4 As shown, when the lobe-shaped rotary piston head gear 1 and the lobe-shaped rotary combustion chamber gear 2 are in harmony, there is a rotary surface seal between the upper and lower end faces of the blade tooth head of the lobe-shaped rotary piston head gear 1 and the inner faces of the front and rear circular clamps of the rotary combustion chamber 3. This rotary sealing surface only plays a sealing role when deflagration is performed; when the two lobe-shaped gears are in harmony, there is a tooth line 17 at the tooth joint on the side of the tooth head. This tooth line is invisible and moves continuously with the rotation of the teeth. It is marked here for the convenience of viewing the figure; this tooth line 17 not only plays a sealing role, but also plays a role in driving the gear to rotate and perform work output. This tooth line 17 is in harmony with the teeth of the lobe-shaped gears. Figure 3 It can be seen that the teeth and lines move and run in with different rotation positions, and all power output is output by this tooth and line 17. At the same time, the teeth and line 17 of the gear work in the high temperature and high pressure area, which will cause the tooth heads of the five-tooth leaf-shaped gears to wear quickly, thereby aggravating the occurrence of air leakage.

[0080] like Figure 4 As shown, an intermediate cylinder block 36 slightly higher than the tooth width is added between the front cylinder block side plate 11 and the rear cylinder block side plate 12 to replace the Figure 2The intermediate spacer block 35 and the intermediate cylinder body 36 can also be made into an integral structure with the front cylinder body side plate 11 or the rear cylinder body side plate 12 to achieve better air tightness. The intermediate cylinder body 36 has two intersecting circular holes slightly larger than the diameter of the tooth top circle of the two leaf-shaped gears. The two leaf-shaped gears are just embedded in the two intersecting circular holes of the intermediate cylinder body 36 for rotation. Figure 4 The middle cylinder body 36 shown is respectively provided with a leaf-shaped rotary piston head gear exhaust high-pressure gas channel 31 (i.e., the first gear high-pressure gas exhaust channel), a rotary combustion chamber exhaust high-pressure gas channel 32 (i.e., the second gear high-pressure gas exhaust channel), a leaf-shaped rotary piston head gear cooling outlet channel 33 (i.e., the first gear cooling gas exhaust channel) and a rotary combustion chamber cooling outlet channel 34 (i.e., the second gear cooling gas exhaust channel). The high-pressure combustion exhaust gas entrained between the first tooth and the second tooth of the leaf-shaped rotary piston head gear 1 and the high-pressure combustion exhaust gas entrained in the No. 1 combustion chamber 8 are respectively rotated to the exhaust port position to spray the high-pressure exhaust gas into the air, and at the same time, the two leaf-shaped gears are rotated to the cooling air inlet to cool and replenish fresh air respectively.

[0081] By using the intermediate cylinder body 36 relative to the intermediate spacer block 35, the intermediate cylinder body 36 can form multiple sealed spaces between the two blade tooth heads of the leaf-shaped rotating piston head gear 1. The intermediate cylinder body 36 can also be separated from the multiple single combustion chambers of the rotating combustion chamber 3 into multiple single sealed chambers. The multiple single sealed chambers separated will only open the sealed state to release air when they rotate to the exhaust port and the cooling air inlet, so that high pressure can be maintained before the air is released. The height of the inner wall of the intermediate cylinder body is slightly larger than the gear tooth width, so that there is a certain gap between the inner wall of the intermediate cylinder body and the gear, which facilitates the free rotation of the gear. Although there is a small gap between the tooth tops of the leaf-shaped tooth heads of the two rotating gears and the intermediate cylinder body 36, high-pressure gas will leak from the gap, but since the two gears rotate for a short time and the amount of leakage is not large, these single sealed chambers still maintain high pressure. For the convenience of description and consistency of reference, these single sealed chambers that maintain high pressure are collectively referred to as high-pressure airtight chambers 19 below. Figure 3 As shown, several high-pressure airtight chambers 19 sandwich the No. 1 combustion chamber 8 in the middle, so that the high-pressure gas burned in the No. 1 combustion chamber 8 is sealed by the high-pressure gas of the adjacent high-pressure airtight chamber 19 and is not easy to leak, so that the high-pressure combustion gas doing work in the aforementioned lobe-shaped rotating piston head gear 1 and the No. 1 combustion chamber 8 continues to be sealed in the high-pressure airtight chamber 19 after leakage due to wear of the tooth head of the lobe-shaped rotating piston head gear 1 and ejected from the No. 1 combustion chamber 8 after doing work, so that the unburned high-pressure gas from the No. 1 combustion chamber 8 continues to burn and pushes the two gears to continue to rotate, so that the fuel working efficiency can be fully utilized and the fuel efficiency is improved.

[0082] In some embodiments, an auxiliary combustion start chamber 18 is also provided in the cylinder body. Figure 4, the combustion gas from the No. 1 combustion chamber 8 on the rotary combustion chamber 3 is separately ejected from the teeth and gears and the high-pressure combustion gas will enter the space formed by the 4th tooth and the 1st tooth of the adjacent leaf-shaped rotary piston head gear 1, the closed space surrounded by the No. 4 combustion chamber and the entire cylinder body. The sealed space containing several combustion chambers is collectively referred to as the auxiliary combustion starting chamber 18 below. The auxiliary combustion starting chamber 18 can play an auxiliary combustion role. When the incompletely burned high-pressure gas ejected from the No. 1 combustion chamber 8 is ejected into the auxiliary combustion starting chamber 18, since the auxiliary combustion starting chamber 18 contains oxygen that has not been completely burned from the previous work and is brought into the new air from the space of the subsequent rotary gear (when the next rotary combustion chamber does not spray oil to work), the high-pressure combustion gas can continue to burn in the auxiliary combustion starting chamber 18 and generate expansion gas to continue to push the two teeth and gears to rotate in opposite directions, thereby Figure 4 It can be seen from above that the local position of the intermediate cylinder body 36 which encloses the auxiliary combustion starting chamber 18 can also be enlarged so that the space of the auxiliary combustion starting chamber 18 is increased so that the residual fuel can be fully burned.

[0083] It should be noted that the design concept of the auxiliary combustion starting chamber 18 can also be applied to rotary engines with other numbers of teeth.

[0084] from Figures 3 to 5 It can also be seen that the five-tooth single rotary combustion chamber rotary engine of the present invention has an air intake chamber 37 set in the space at a symmetrical position of the auxiliary combustion starting chamber with the line connecting the leaf-shaped rotary piston head gear shaft 21 and the rotary combustion chamber shaft 22 as the center line. The No. 1 combustion chamber 8 on the rotary combustion chamber 3 is in a closed space surrounded by the space formed by the leaf-shaped tooth head of the 4th tooth and the 1st tooth of the leaf-shaped rotary piston head gear 1, the No. 4 combustion chamber and the entire cylinder body. Hereinafter, this sealed space containing several combustion chambers is collectively referred to as the air intake chamber 37. This air intake chamber 37 can play a role in keeping fresh air from being transported to the sealed space of the combustion chamber. At the same time, an air intake chamber high-pressure gas inlet 103 and a rotary combustion chamber cooling air intake channel 39 are opened on the cylinder body at the position of the air intake chamber 37 (see Figure 6 ), various gas boosting equipment such as turbo compressors (such as turbochargers 104), mechanical compressors (such as mechanical superchargers 105) and high-pressure gas output from the air chamber of a star engine similar to piston compression can be compressed into the high-pressure gas through this inlet. Fig. 27 As shown, the gas inlet of the turbocharger 104 extends to the first gear row high pressure gas passage in the cylinder body or is connected to the second gear row high pressure gas passage in the cylinder body, or both are connected; Fig. 27 As shown, a plurality of high-pressure gas pistons 106 are connected by a movable connecting rod 108, and the movable connecting rod 108 is parallel to the rotating rod 107. The rotating rod 107 is driven to rotate by the gear shaft of the first gear. Of course, this piston gas boosting device can also be installed on the gear shaft of the second gear to drive the rotation, or installed on both shafts; Fig. 27 As shown, a belt 110 is mounted on a pulley 109 installed on the second gear shaft, and the belt drives the pulley 109 on the supercharger rotating shaft 112 of the supercharger 105 to rotate, and high-pressure gas is generated by the supercharger 105. The supercharger 105 can also be connected to the first gear shaft or both shafts are connected; the high-pressure gas generated by the above-mentioned gas boosting equipment can be Figure 4 and Figure 5 The high pressure air inlet 103 on the Figure 6 , Fig.28a and Fig.28b The cooling air intake passage 39 of the rotating combustion chamber is connected to the oil discharge passage 113, so that the high-pressure air filled into the No. 1 combustion chamber 8 before the rotating gear is in the air intake chamber 37 position, and then rotates into the gear position and is compressed again, so that the compression ratio of the gas in the combustion chamber before combustion can meet the requirements, so that diesel compression ignition can be realized; Fig.28a and 28b Another installation method of the supercharger 105 can be seen. In these two figures, it can be seen that the supercharger rotating shaft 112 of the supercharger 105 is synchronously rotated and connected with the first leaf-shaped gear shaft 21. This installation method can omit the pulley 109 and the belt 110, and can further simplify the structure of the rotary engine of the present invention. Of course, the supercharger rotating shaft 112 of the supercharger 105 is synchronously rotated and connected with the first leaf-shaped gear shaft 21.

[0085] It should be noted that the design concept of the supercharging equipment can also be applied to rotary engines with other numbers of teeth.

[0086] from Figures 3 to 5 The five-tooth single-rotating combustion chamber rotor engine of the present invention can achieve the following effects:

[0087] Effect 1, the rotary combustion chamber 3 composed of a five-toothed leaf-shaped rotating gear and a pair of circular clamping plates clamping it has only gear teeth and openings in the direction, which fully ensures the sealing of the five rotary combustion chambers, so that the problem of gas leakage in the combustion chamber is greatly solved. At the same time, only the five leaf-shaped tooth heads are in contact with the rotary combustion chamber 3, so that Figure 3 It can be seen that the fuel sprayed from the injector can also be used as a lubricant for the gear end face 16 of the leaf-shaped rotary piston head gear 1 and the inner surface of the circular clamping plate of the rotary combustion chamber 3, so no engine oil lubrication is required, reducing or even avoiding the engine oil participating in the combustion in the rotary combustion chamber 3. At the same time, the carbon deposits inside the rotary combustion chamber 3 can also lubricate the teeth and wear of the gears.

[0088] Effect 2, by adding an intermediate cylinder body 36 between the front cylinder body side plate 11 and the rear cylinder body side plate 12, the high-pressure airtight chamber 19 can seal the combustion high-pressure gas ejected from the No. 1 combustion chamber 8, so that even if the two lobe-shaped tooth heads are worn and leaking, the leaked high-pressure gas will continue to be sealed in the auxiliary combustion starting chamber 18 to continue to burn and do work, and there is no need to frequently replace the two lobe-shaped gear components, so that all the deflagration high-pressure gas can only be discharged from the exhaust channel. In this sealed exhaust process, the deflagration high-pressure gas can fully and completely drive the two lobe-shaped gear shafts to rotate to output power and do work.

[0089] Effect 3, oil lubrication is added between the gear end face 16 of the above-mentioned leaf-shaped rotary piston head gear 1 and the inner walls of the front cylinder side plate 11 and the rear cylinder side plate 12, and between the above-mentioned rotary combustion chamber circular clamping plate hole 25 and the outer wall of the rotary combustion chamber 3, so that the leaf-shaped rotary piston head gear 1 and the rotary combustion chamber 3 sealed and clamped by the front cylinder side plate 11 and the rear cylinder side plate 12 rotate in opposite directions to each other; at the same time, since the rotating space gap is very small, the engine oil produces a high-pressure engine oil seal at the edge of the gear due to the high-speed centrifugal rotation of the gear, so that the high-pressure combustion gas in the auxiliary combustion starting chamber 18 is sealed by the engine oil in this gap, which has the effect of reducing the leakage of the high-pressure combustion gas.

[0090] Effect 4, the problem of low compression ratio of combustion gas in the active rotating combustion chamber 3 of the blade-shaped rotating gear rotor engine of the present invention can be solved by the gas boosting device driven by the gear rotating shaft and the high-pressure gas inlet 103 and the rotating combustion chamber cooling intake passage 39 opened on the cylinder body of the intake chamber 37.

[0091] Through the above four measures, the problems of rotary engine burning oil, incomplete fuel combustion, low compression ratio of combustion chamber gas, air leakage, easy wear of parts and maintenance and replacement of parts after a short working time have been greatly solved. Since the rotary combustion chamber 3 as a combustion chamber is a rotating component, the increase in the number of teeth and the formation of multiple combustion chambers and high-pressure airtight chamber 19 improve the sealing of the single rotary combustion chamber rotary engine, avoid the easy leakage of high-pressure sealed gas, and improve the efficiency of work, the introduction of gas boosting equipment can not only improve the compression ratio of the combustion gas in the rotary combustion chamber 3, but also support diesel compression ignition.

[0092] Special note here: Figure 3 In this example, the tooth widths of the first gear and the second gear are consistent, but in other embodiments, they may not be completely consistent. The tooth width of the first gear may be smaller than the tooth width of the second gear, but due to space limitations, the description and illustration are omitted. In this example, the tooth width of the first gear cannot be greater than the tooth width of the second gear, otherwise the first gear will collide with the two circular clamping plates on the second gear, causing the gears to be unable to rotate with each other.

[0093] Third embodiment

[0094] like Figure 6 and Figure 7 As shown, this embodiment is a six-tooth single-rotating combustion chamber rotary engine composed of a pair of six-tooth lobe gears, and the principle is the same as the first and second embodiments.

[0095] like Figure 6 As shown, from the sealing, compression, fuel injection combustion to the opening of the power process, as well as the exhaust and intake process afterwards, the six-tooth engine has one more combustion chamber than the five-tooth engine, and the compression ratio of the No. 1 combustion chamber 8 is smaller. Compared with the first and second embodiments, Figure 7 The following improvements were made to the six-tooth single rotating combustion chamber rotor engine:

[0096] like Figure 7 As shown, on the front cylinder side plate 11 and the rear cylinder side plate 12, a leaf-shaped rotating piston head gear cooling air inlet 38 is respectively opened on the front cylinder side plate 11 and the rear cylinder side plate 12 near the position of the leaf-shaped rotating piston head gear shaft 21. When the leaf-shaped tooth head No. 1 of the leaf-shaped rotating piston head gear 1 completes the work, it rotates to the leaf-shaped rotating piston head gear exhaust high-pressure air channel 31 to discharge the high-pressure combustion exhaust gas entrained from the space between the first blade tooth head and the second blade tooth head. When the air pressure of this space is consistent with that of the external space, the remaining exhaust gas is not easy to be discharged again. This exhaust gas space continues to rotate to the opening of the leaf-shaped rotating piston head gear cooling outlet channel 33, and this exhaust gas space is also connected to the leaf-shaped rotating piston head gear cooling air inlet 38. Since the lobe-shaped rotary piston head gear 1 rotates at a very high speed, it can be regarded as a centrifugal rotary fan. External air is sucked in through the lobe-shaped rotary piston head gear cooling air inlet 38, and the exhaust gas is discharged from the lobe-shaped rotary piston head gear 1 cooling air outlet channel 33. At the same time, the fresh air sucked in from the outside cools the entire lobe-shaped rotary piston head gear 1. The lobe-shaped rotary piston head gear cooling air outlet channel 33 can also be eliminated, and one of the two lobe-shaped rotary piston head gear cooling air inlets 38 of the front cylinder body side plate 11 and the rear cylinder body side plate 12 can be used as the air outlet, and the other lobe-shaped rotary piston head gear cooling air inlet 38 is connected to the high-pressure gas outlet of the gas boosting equipment, and forced air is supplied in and out to cool the lobe-shaped rotary piston head gear 1 while exhausting the exhaust gas. Fig. 27 There is a connection structure for gas boosting equipment such as a turbocharger and a supercharger; the right rotary combustion chamber 3 is located at the rear of the rotary combustion chamber cooling outlet channel 34 in the rotation direction, and a rotary combustion chamber cooling intake channel 39 is opened on the side wall of the middle cylinder body 36. Air can be blown into the rotary combustion chamber cooling intake channel 39 by devices such as turbochargers and superchargers to take away the exhaust gas in the No. 1 combustion chamber 8 where work is completed by the rotary combustion chamber 3, while cooling the No. 1 combustion chamber 8 and the gears.

[0097] like Figure 6As shown, the combustion gas of combustion chamber 18 is ejected separately from the gears of the gears, and the high-pressure combustion gas is ejected into the auxiliary combustion start chamber 18. Since the auxiliary combustion start chamber 18 contains oxygen from the previous work that has not been completely burned and the new air brought into the space of the rotating gears, the high-pressure combustion gas can continue to burn in the auxiliary combustion start chamber 18 and generate expansion gas to continue to push the two gears to rotate in the opposite direction. Figure 6 As shown, a part of the entire cylinder body surrounding the auxiliary combustion starting chamber is removed to expand the auxiliary combustion starting chamber 18, thereby increasing the auxiliary combustion space so that the residual fuel can be fully burned in this space.

[0098] An auxiliary combustion starting chamber fuel injector 51 and an auxiliary combustion starting chamber spark plug 52 are installed on the side wall of the middle cylinder body 36 of the auxiliary combustion starting chamber 18, which can be used as the rotational power when the six-tooth single rotating combustion chamber rotor engine of the present invention is started. When the engine is started, the auxiliary combustion starting chamber fuel injector 51 continuously sprays fuel mist into the auxiliary combustion starting chamber 18 at a certain interval, and then the auxiliary combustion starting chamber spark plug 52 continuously ignites the fuel and the gas mixed with the original gas in the auxiliary combustion starting chamber 18 at a certain interval. The expansion of the high-pressure gas caused by the combustion of the fuel pushes the two gears with teeth to rotate in opposite directions. When the No. 1 combustion chamber rotates to the tooth position, the rotating combustion chamber 3 starts normal fuel injection and ignition work, and at this time the auxiliary combustion starting chamber fuel injector 51 and the auxiliary combustion starting chamber spark plug 52 stop working.

[0099] When the tooth head of the left leaf-shaped rotary piston head gear 1 and the teeth of the No. 1 combustion chamber 8 are sealed, the fuel injector 13 and the spark plug 14 at the root of the teeth in the No. 1 combustion chamber 8 start the engine to work normally, and the fuel injector 51 and the spark plug 52 in the auxiliary combustion starting chamber complete the engine starting task and stop working. Of course, if the fuel injectors and spark plugs in each combustion chamber of the rotary combustion chamber 3 work normally, if it is necessary to increase the engine output power or increase the torque output (this is because the torque when the rotary combustion chamber 3 teeth and position do work does not have the auxiliary combustion starting The torque of chamber 18 is large, which is caused by the rotation position of the gear). In addition to increasing the throttle to increase the injection amount of the injector 13 of each combustion chamber of the rotating combustion chamber 3, the injector 51 of the auxiliary combustion starting chamber can also spray oil mist. When the combustion gas of combustion chamber No. 1 8 is sprayed into the auxiliary combustion starting chamber 18, the oil mist sprayed into the auxiliary combustion starting chamber 18 by the injector 51 of the auxiliary combustion starting chamber will be ignited, which is equivalent to increasing the amount of oil in each single combustion chamber, increasing the output power and torque of the engine, reducing the gear position of the gear clutch, and reducing the complexity and weight of the gear clutch.

[0100] like Figure 7As shown, a fluid pipeline high-speed rotating joint 45, an oil inlet pipe 47 and a high-speed rotating conductive slip ring 46 are installed on one end of the rotating combustion chamber shaft 22. The hollow rotating combustion chamber shaft 22 can deliver fuel and transmit ignition signals to the injectors 13 and spark plugs 14 in a single combustion chamber in the rotating combustion chamber 3 respectively.

[0101] from Figure 6 to Figure 7 The six-tooth single rotating combustion chamber rotor engine of the present invention has the following beneficial effects:

[0102] Effect 1. An auxiliary combustion starting chamber fuel injector 51 and an auxiliary combustion starting chamber spark plug 52 are installed on the inner wall of the middle cylinder body 36 of the auxiliary combustion starting chamber 18. By injecting fuel into the auxiliary combustion starting chamber 18 and igniting it, the gas combustion drives the leaf-shaped rotating piston head gear 1 and the rotating combustion chamber 3 rotating teeth and starts to work normally. When the engine is started, there is no need to install an auxiliary starting motor, which reduces the auxiliary equipment of the engine and thus reduces the overall weight of the engine.

[0103] Effect 2, by opening the leaf-shaped rotary piston head gear cooling air inlet 38 on the front cylinder side plate 11 and the rear cylinder side plate 12, the entire leaf-shaped rotary piston head gear 1 can be fully cooled while the combustion exhaust gas entrained between the two tooth heads of the leaf-shaped rotary piston head gear 1 is discharged and fresh air is input.

[0104] Effect 3: In each single combustion chamber of the rotary combustion chamber 3, a fuel injector 13 and a spark plug 14 are installed at the root of the tooth, which reduces the wear on the side of the leaf-shaped tooth head of the leaf-shaped rotary piston head gear 1.

[0105] Effect 4: A pair of identical leaf-shaped rotating piston head gear shafts, leaf-shaped rotating piston head gear shaft, auxiliary gears 41 and auxiliary gears 42 on the rotating combustion chamber shaft are installed on the outer side of the front cylinder side plate 11 and the rear cylinder side plate 12 on the leaf-shaped rotating piston head gear shaft 21 and the rotating combustion chamber shaft 22. These two gears are synchronous rotating gears of the same size and shape (or may not be the same). Under the rotation driven by the leaf-shaped rotating piston head gear shaft 21 and the rotating combustion chamber shaft 22, this pair of auxiliary gears also synchronize their teeth and rotation. At the same time, when the two leaf-shaped gears are driven to rotate by the combustion chamber gas, the torque of the two leaf-shaped gears is transmitted to the pair of ordinary gears through the leaf-shaped rotating piston head gear shaft 21 and the rotating combustion chamber shaft 22, and the rotational torque is synchronously transmitted to the power output gear 100 (this gear can use a ratchet) to output rotational power, which is equivalent to increasing the length of the two leaf-shaped gear teeth and line 17, thereby reducing the wear of the tooth heads of the two leaf-shaped gears and extending the service life of the two leaf-shaped gears; the above-mentioned two auxiliary gears can also be directly used as power output gears to output power.

[0106] Effect 5: Through the rotary combustion chamber cooling outlet passage 34, the carbon deposits can be cleaned directly with a cleaning tool deep into the rotary combustion chamber 3 without disassembling and opening the interior of the engine, which greatly improves the maintainability of the rotary engine of the present invention.

[0107] Through the above features, adding an auxiliary gear can solve the problem that the two leaf-shaped gear parts are easy to wear and need frequent maintenance and replacement; at the same time, adding an auxiliary combustion starting chamber fuel injector 51 and an auxiliary combustion starting chamber spark plug 52 to the auxiliary combustion starting chamber 18 also makes the six-tooth single-rotating combustion chamber rotor engine of the present invention no longer require auxiliary equipment (starting motor) and reduces the weight of the engine; by opening a leaf-shaped rotating piston head gear cooling inlet 38 on the front cylinder side plate 11 and the rear cylinder side plate 12, the entire leaf-shaped rotating piston head gear 1 can be fully cooled and exhaust gas can be discharged and fresh air can be input.

[0108] Fourth embodiment

[0109] like Figure 8a-Figure 13 As shown, this embodiment provides a seven-tooth single-rotation combustion chamber rotor engine composed of a pair of seven-tooth blade gears. The above embodiments have the same principle, from sealing, compression, fuel injection combustion, sealing to exhaust and the entire process of air intake.

[0110] Figure 8a , Figure 8b , Figure 8c The three positions of the gear rotation are shown. The engine with seven teeth has one more combustion chamber than the engine with six teeth. It can be understood that the number of the lobe-shaped tooth heads of the lobe-shaped rotating combustion chamber gear 2 determines the maximum number of combustion chambers. The number of lobe-shaped tooth heads determines the number of combustion chambers that can be provided. At the same time, the spatial compression ratio of the No. 1 combustion chamber 8 is smaller than that of the combustion chamber of the engine of the third embodiment, which also shows that the compression ratio decreases as the number of teeth of the lobe-shaped rotating combustion chamber gear increases.

[0111] like Figure 8a , Figure 8b , Figure 8c As shown, the seven-tooth single-rotating combustion chamber rotor engine composed of a seven-tooth blade gear has the following improvements:

[0112] exist Figure 8a , Figure 8b , Figure 8cIn the structure of mutual tooth coordination composed of a pair of seven-toothed lobe gears, the lobe-shaped rotary piston head gear 1 rotates between the front cylinder body side plate 11 and the rear cylinder body side plate 12, and the diameters of the two front and rear circular clamping plates constituting the rotary combustion chamber 3 are larger than the tooth top circle diameter of the lobe-shaped rotary piston head gear 1 on the right, so that the rotating arc gap of the front and rear circular clamping plates of the lobe-shaped rotary combustion chamber gear is moved from the middle position across the auxiliary combustion start chamber 18 to the edge of the auxiliary combustion start chamber 18. Due to the high-speed rotation of the lobe-shaped gear, the rotating gap of the front circular clamping plate of the multi-rotating combustion chamber is separated by the high-pressure airtight chamber 19 of the lobe-shaped rotary piston head gear 1 formed by the left rotation, which reduces the leakage of the gas burned in the auxiliary combustion start chamber 18, and at the same time increases the tooth root circle diameter of the lobe-shaped rotary piston head gear 1 on the left. It can be seen that the lengths of the rotating gap 49 of the front circular clamping plate of the multi-rotating combustion chamber and the rotating gap of the rear circular clamping plate of the rotary combustion chamber are reduced, the amount of air leakage caused by the arc gap is significantly reduced, and the oil seeping from the gap is reduced to participate in the combustion in the auxiliary combustion start chamber 18.

[0113] like Figure 8a , Figure 8b , Figure 8c As shown, the cooling air inlet passage of the rotary combustion chamber is changed to a centrifugal fan blade 53 installed in the passage, and the centrifugal fan blade 53 is installed on the centrifugal fan shaft 54, and is connected and rotated with the rotary combustion chamber shaft centrifugal fan gear 71 installed on the rotary combustion chamber shaft 22 through the centrifugal fan gear 72 and the centrifugal fan gear chain 75 on the shaft (it can also be connected and rotated by two pulleys and belts), driving the centrifugal fan to rotate and blow air to each combustion chamber in the rotary combustion chamber 3 through the two centrifugal fan air inlets 55 opened on the front cylinder side plate 11 and the rear cylinder side plate 12. The centrifugal fan air inlet mounting bracket 56 is on the front cylinder side plate 11 and the rear cylinder side plate 12, and the cross-shaped hollow bracket can also serve as the centrifugal fan air inlet 55. At the same time, the blade width of the centrifugal fan blade 53 is smaller than the tooth width of the blade-shaped rotary combustion chamber gear 2, so as to facilitate the combustion exhaust gas in the combustion chamber to be replaced by fresh air and discharged from the rotary combustion chamber cooling air outlet passage 34.

[0114] like Figure 8a , Figure 8b , Figure 8c , Fig.11 and Fig.13 As shown, an air-closing ring 111 is provided on the root end face of the first gear and the outer end face of the circular clamping plate of the second gear. The air-closing ring 111 rotates with the first gear 1 and the second gear 2, and combines the oil lubrication and oil sealing effect to ensure the air tightness of the rotating end face and the inner surface of the cylinder body when rotating, so that the high-pressure gas will not leak from the two rotating gear shafts.

[0115] It should be noted that the design concept of the air-closing ring 111 can also be applied to rotary engines with other numbers of teeth.

[0116] like Figure 8a , Figure 8b , Figure 8c , Fig.11 and Fig.13 As shown, a high-pressure gas inlet 103 of the air inlet chamber 37 is opened near the leaf-shaped rotary piston head gear cooling outlet passage 33 in the middle cylinder body 36 and connected to the Fig. 27 At the high-pressure gas outlet of the gas boosting device, the high-pressure gas of the gas boosting device is pressed into the high-pressure airtight chamber 19 and the intake chamber 37 through the high-pressure gas inlet 103 of the intake chamber and is brought into the teeth and space by the rotating gears, so that the gas compression ratio in the rotating combustion chamber 3 is very high, meeting the gas compression combustion requirements; the design of this high-pressure gas inlet 103 can completely replace the function of the above-mentioned centrifugal fan equipment.

[0117] Also different from the third embodiment is that the rotary combustion chamber shaft hole 65 opened on the front cylinder side plate 11 and the rear cylinder side plate 12 is changed into a rotary combustion chamber shaft bracket 62 and a rotary combustion chamber shaft clamping plate cylinder opening 63, and a bearing wheel can be installed in the center hole of the rotary combustion chamber shaft bracket 62 to insert the rotary combustion chamber shaft 22 for rotation, and the rotary combustion chamber shaft clamping plate cylinder opening 63 is smaller than the diameter of the front and rear circular clamping plates of the leaf-shaped rotary combustion chamber gear, and the fuel injector 13 and the spark plug 14 are respectively installed on the rotary combustion chamber front circular clamping plate 23 and the rotary combustion chamber rear circular clamping plate 24 and can pass through the above-mentioned rotary combustion chamber shaft bracket 62 and the rotary combustion chamber shaft clamping plate cylinder opening 6 The 3 places are installed and replaced, and the rotary combustion chamber 3 can dissipate heat through the rotary combustion chamber shaft clamp cylinder opening 63 on the two cylinder bodies, which solves the problem that the spark plug in the rotary combustion chamber 3 of the front 6-tooth leaf gear is inconvenient to replace and needs to be disassembled for replacement. An annular cover plate can also be installed at the rotary combustion chamber shaft bracket 62 and the rotary combustion chamber shaft clamp cylinder opening 63 to close the opening, which can be opened when the spark plug and the injector need to be replaced. The annular cover plate also has dust-proof and gas pressure-maintaining functions, so that the high-pressure combustion gas in the auxiliary combustion starting chamber 18 is not easy to leak from the rotary combustion chamber shaft clamp cylinder opening 63.

[0118] The above-mentioned structure of the rotating combustion chamber shaft bracket 62 and the rotating combustion chamber shaft clamp cylinder opening 63 can also be applied to the first gear shaft; it should be noted that the design concept of this structure can also be applied to rotary engines with other numbers of teeth.

[0119] The cylinder body is provided with a position trigger at the rotary combustion chamber, the fuel injector contact 76 of the position trigger is used to trigger the fuel injector of the closed rotary combustion chamber to inject fuel, and the spark plug contact 77 of the position trigger is used to trigger the spark plug of the closed rotary combustion chamber to ignite. In different embodiments, the form of the position trigger is different.

[0120] Combine the following Figure 9aThe internal structure diagram of the seven-tooth single rotary combustion chamber rotary engine can provide a detailed understanding of the structure of each part. The lobe-shaped rotary piston head gear 1 on the left and the lobe-shaped rotary combustion chamber gear 2 on the right are respectively mounted on their respective rotating shafts (i.e., the lobe-shaped rotary piston head gear shaft 21 on the left and the rotary combustion chamber shaft 22 on the right), and rotate synchronously. The two seven-tooth lobe-shaped gears can rotate in opposite directions to each other. The lobe-shaped rotary combustion chamber gear 2 on the right and the rotary combustion chamber front circular clamping plate 23 and the rotary combustion chamber rear circular clamping plate 24 together form an integrated rotary combustion chamber 3. There are a total of seven tooth heads on the lobe-shaped rotary piston head gear 1 on the left (see numbers 1-7 in the figure), and the rotary combustion chamber 3 on the right is semi-enclosed. Each combustion chamber also has seven combustion chambers (1-7). The leaf-shaped tooth head No. 1 on the left leaf-shaped rotary piston head gear 1 and the two adjacent gear tooth heads forming the No. 1 combustion chamber 8 are toothed and rotated in sequence with each other, and a synchronous rotating cam 73 is also installed on the outside of the front cylinder side plate 11 on the left leaf-shaped rotary piston head gear shaft 21, and a cam contactor 74 (a form of position trigger) is installed on the front cylinder side plate 11. The rear cylinder side plate 12 is respectively equipped with a leaf-shaped rotary piston head gear shaft auxiliary gear 41 on the leaf-shaped rotary piston head gear shaft 21 and the rotary combustion chamber shaft 22, as shown Fig.12 As shown, the auxiliary gear 41 on the leaf-shaped rotary piston head gear shaft is an ordinary gear of the same size and shape. The two gears also rotate with each other and play the same role as the auxiliary gear 41 on the leaf-shaped rotary piston head gear shaft in the third embodiment; an oil inlet pipe 47 is connected to one end of the rotary combustion chamber shaft 22 on the right side of the front cylinder side plate 11 outside through a high-speed rotary joint 45 installed with a fluid pipeline. The rotary combustion chamber shaft 22 on the right is a hollow tube that can input fuel to the fuel injector 13 on the aforementioned rotary combustion chamber front circular clamping plate 23; a high-speed rotating conductive slip ring 46 is also installed on the outside of the rear cylinder side plate 12 at the other end of the rotary combustion chamber shaft 22. The high-speed rotating conductive slip ring 46 controls the operation of the 7 fuel injectors 13 and 7 spark plugs 14 installed on the rotary combustion chamber rear circular clamping plate 24 on the rotary combustion chamber 3 by transmitting the electrical signal from the central electronic control device. The auxiliary gear 41 on the leaf-shaped rotary piston head gear shaft and the auxiliary gear 42 on the rotary combustion chamber shaft are toothed together and rotate synchronously in the same direction as the leaf-shaped rotary piston head gear 1 and the leaf-shaped rotary combustion chamber gear. It can be seen from the figure that the front cylinder side plate 11 and the rear cylinder side plate 12 together wrap the intermediate cylinder 36, the leaf-shaped rotary piston head gear 1 and the entire rotary combustion chamber 3 in the cylinder body, and two leaf-shaped rotary combustion chamber gear circular splint hole sockets slightly larger than the diameters of the rotary combustion chamber front circular splint 23 and the rotary combustion chamber rear circular splint 24 are respectively opened on the front cylinder side plate 11 and the rear cylinder side plate 12, so that the rotary combustion chamber front circular splint 23 and the rotary combustion chamber rear circular splint 24 with engine oil added in these two hole sockets can rotate smoothly.

[0121] Combine the following Figures 8a to 13 The schematic diagram of the invention details the working process of the seven-tooth blade gear rotary combustion chamber engine of the present invention:

[0122] exist Figure 8a It can be seen that the leaf-shaped rotary piston head gear 1 on the left and the leaf-shaped rotary combustion chamber gear with the same number of teeth on the right can mesh and rotate with each other, and the rotation directions are opposite. When the fuel injector of the auxiliary combustion starting chamber sprays fuel spray into the auxiliary combustion starting chamber, and then the spark plug in the auxiliary combustion starting chamber starts to ignite, the combustion gas mixed with fuel spray and air begins to burn and expand, thereby pushing the two gears on both sides of the auxiliary combustion starting chamber to rotate in opposite directions. Figure 8a The lobe-shaped rotary piston head gear 1 shown in the figure is designated as the lobe-shaped tooth head No. 1 and the rotary combustion chamber 3 on the right is composed of two front and rear circular clamping plates and the lobe-shaped rotary combustion chamber gear, wherein the lobe-shaped tooth heads on both sides of the No. 1 combustion chamber 8 rotate to the teeth and positions (the seven groups of lobe-shaped tooth head numbers and the corresponding combustion chamber single zone numbers are internally determined in the central electronic control device, and it is determined which group of lobe-shaped tooth heads and the corresponding No. 1 combustion chamber 8 combustion space are the corresponding teeth and combustion spaces), Figure 8a The middle tooth and the left leaf-shaped tooth head No. 1 seal the combustion space of the No. 1 combustion chamber 8. Figure 9b2 The location of the diagram, in Figure 9b1 As shown in the figure, a synchronous rotating cam 73 is installed on the leaf-shaped rotating piston head gear shaft 21, and there are two rows of 7 convex points on the synchronous rotating cam 73. A synchronous rotating cam contactor 74 (a form of position trigger) is installed on the rear cylinder side plate 12 close to the synchronous rotating cam 73, and two rows of contact blocks are installed on it. The synchronous rotating cam fuel No. 1 convex contact point 81 representing one of the 7 combustion chamber injectors on the synchronous rotating cam 73 touches the injector contact 76 on the cam contactor 74. The electrical signal generated by this contact block is received by the central electronic controller of the engine and sends a control signal through the high-speed rotating conductive slip ring 46 to control the injector 13 in the combustion space of the No. 1 combustion chamber 8 to start spraying oil mist into the combustion space of the single zone 1; when the two gears continue to rotate, because they are leaf-shaped gears with the same number of teeth and diameter, the two leaf-shaped gears and the synchronous rotating cam 73 have the same rotation angular velocity. Because the angular velocity is the same, the synchronous rotating cam 73 can be installed on the leaf-shaped rotating piston head gear shaft 21 or the rotating combustion chamber shaft 22.

[0123] Depend on Figure 8b and Figure 9b4 The same is shown in the figure. The lobe-shaped tooth head No. 1 and the first single-zone combustion space on the right have been compressed to the minimum space by the teeth. At this time Figure 9b3What is shown is that at this time, the synchronous rotating cam spark plug No. 1 convex touch point 82 in the convex point representing the 7 combustion chamber spark plugs in the lower row of the synchronous rotating cam 73 rotates and collides with the spark plug contact 77 below the synchronous rotating cam contactor 74. The electrical signal generated by this contact block is received by the central electronic controller of the engine to generate a control signal, which controls the spark plug in the combustion space of the No. 1 combustion chamber 8 through the high-speed rotating conductive slip ring 46 to start ignition and ignite the mixed combustion gas of the first single-zone combustion space spray mist and air, thereby starting the explosion. The high-temperature and high-pressure expansion gas after combustion pushes the two teeth and the leaf-shaped gears in the closed single-zone 1 combustion space to accelerate the reverse rotation and separation, and Figure 8c It can be seen that when the counter-rotating teeth and tooth heads of the two lobe gears are separated, the rotational positions of the two lobe gears are opened at this moment when the space closed by the lobe tooth head No. 1 in the single zone 1 combustion space is opened.

[0124] Also see Fig.21a , Figure 21b The synchronous rotating hole wheel 91 and the synchronous rotating hole wheel photoelectric transmitter receiver 92 (another form of position trigger) have the same functions as the above-mentioned synchronous rotating cam 73 and synchronous rotating cam contactor 74, except that the principle is to use the electrical signal received by photoelectric rather than the electrical signal converted by the physical contact of the cam. If the rotation angular speed of the leaf-shaped rotating piston head gear shaft 21 and the rotating combustion chamber shaft 22 are the same, these two methods can be installed on one of the two shafts. If the rotation angular speeds of the two shafts are inconsistent, they can only be installed on the rotating combustion chamber shaft 22 (shown in the eighth embodiment).

[0125] When the first single-zone combustion space closed by the first lobe-shaped tooth head is opened, the high-temperature and high-pressure gas originally closed in the closed single-zone 1 combustion space is sprayed into the auxiliary combustion starting chamber 18 from this opening and mixed with the fresh low-pressure air originally in the auxiliary combustion starting chamber 18 to fully burn and continue to expand. The expanded high-temperature and high-pressure gas after combustion acts on the inner side walls of the left and right lobe gears in the auxiliary combustion starting chamber 18, pushing the two lobe gears to continue to accelerate their rotation. While the high-temperature and high-pressure gas pushes the two lobe gears to rotate at high speed, it continuously forms a high-pressure airtight chamber 19 between the adjacent tooth heads on both sides to take away the completely burned combustion exhaust gas. Figure 8c It can be seen that the seven-tooth lobe gear rotary combustion chamber engine of the present invention forms two high-pressure airtight chambers 19 on the left and right sides. Since the gears rotate at high speed, the two high-pressure airtight chambers 19 can completely seal the gap between the two lobe gear tooth tops and the middle cylinder body. The two lobe gear tooth tops do not need to contact the middle cylinder body to ensure airtightness, and there is no problem of mutual contact and friction damaging the cylinder body and tooth tops. At the same time, Figure 2 , Fig.28a and Fig.28bIt can be seen that the oil added to the oil port 10 on the front and rear cylinder side panels flows along the tooth end faces of the two-lobed gears or the outer end faces of the front and rear circular clamping plates of the rotating combustion chamber, and is thrown to the tooth tops of the two-lobed gears by centrifugal force during high-speed rotation, and can also play an oil sealing role for the tooth tops of the high-pressure airtight chamber 19; this air seal and oil seal also makes the aforementioned left first lobe-shaped tooth head seal the combustion space of the No. 1 combustion chamber 8 with teeth and rotate to do work, and the problem that the tooth heads of the two-lobed gears are easy to wear and need to be replaced frequently is alleviated, because even if the tooth head is worn, the high-temperature and high-pressure gas ignited and burned in the rotating combustion chamber is easy to leak in small amounts, but the leaked small amount of high-temperature and high-pressure gas is not directly discharged into the air for waste, but is still sealed by the auxiliary combustion starting chamber 18 and the air intake chamber 37 on both sides of the teeth and position, so there is no need to frequently replace the worn two-lobed rotating gears; from Figure 6 , Figure 8a , Figure 8b and Figure 8c It can be seen that as the number of teeth of the leaf-shaped gear increases, the number of corresponding high-pressure airtight chambers 19 also increases. Not only are there high-pressure airtight chambers 19 on both sides of the auxiliary combustion start chamber 18, but also Figure 8c It can be seen from the figure that as the number of teeth of the leaf-shaped gear increases, high-pressure airtight chambers 19 can be provided on both sides of the air inlet chamber 37. Similarly, these high-pressure airtight chambers 19 can also prevent the internal high-pressure gas from leaking, thereby improving the airtightness.

[0126] At the same time Fig.28a and Fig.28b The structure of the oil delivery channel of the rotary engine of the present invention can be seen in FIG. Fig.28a This is the oil channel structure diagram of the engine with the gear shaft installed vertically. Fig.28aIt can be seen that the high-pressure gas inlet 103, the rotary combustion chamber cooling intake channel 39 or the oil discharge channel 113 are opened on the intermediate cylinder body 36 near the intake chamber 37. The channel opening is approximately long and connected to the first gear 1 and the second gear of the intake chamber 37 or the high-pressure airtight chamber 19 next to the intake chamber 37. The length of the long opening is approximately the same as the tooth width of the leaf gear. The high-pressure air inlet 115 of these channels is connected to the high-pressure gas outlet of the aforementioned gas boosting device, and a semi-enclosed oil collector 114 is installed at the lower part of the channel near the ground. An oil filter is installed on the inside of the oil collector 114, and an oil output pipe 116 is provided at the bottom of the oil collector 114 to connect to the oil port; the rotor When the engine is working, the blade-shaped gear rotates, and the oil at the tooth end is thrown to the gear tooth top due to the centrifugal force of rotation. When the gear tooth top carries the oil through the long strip opening of the above-mentioned channel, it is thrown into the high-pressure gas inlet 103, the rotary combustion chamber cooling intake channel 39 or the oil discharge channel 113. Since the oil collector 114 is at the lowest end of the above-mentioned channel, the oil flows into the oil collector 114 due to gravity and flows to the bottom end of the oil collector 114 through the oil filter. At the same time, since the other end of the above-mentioned channel is connected to the high-pressure gas outlet of the aforementioned gas boosting device, the entire channel has a high gas pressure when the rotary engine is working, so the oil collector 114 also has a high pressure inside, so that the oil at the bottom is pressed out from the oil output pipe at the bottom and enters Figure 2 , Fig.28a and Fig.28b The oil port 10 on the upper part makes the oil recycled and not easy to be brought into the rotating combustion chamber 3 of the two-lobed gear teeth and burn to pollute the environment; Fig.28b This is the oil channel structure diagram of the engine with the gear shaft installed horizontally. Fig.28b Visible and Fig.28aThe only difference is that the installation position of the oil collector 114 is changed to the lowest point near the ground, and the high-pressure gas inlet 103, the rotary combustion chamber cooling air intake channel 39 or the oil discharge channel 113 are just named differently. In fact, their functions are the same. They all press high-pressure gas into the air intake chamber 37 and the adjacent high-pressure airtight chamber 19 while collecting lubricating oil. If the rotary combustion chamber cooling air intake channel 39 leads to the rotary combustion chamber cooling air outlet channel 34 to press high-pressure gas, the introduced high-pressure gas also has a cooling and ventilation effect, and when the gears rotate to form a high The compressed airtight chamber 19 rotates and the combustion chamber cools the intake passage 39, which becomes a high-pressure gas inlet 103 to press high-pressure gas into the high-pressure airtight chamber 19. When the high-pressure airtight chamber 19 continues to rotate, it becomes an intake chamber 37 again to continue to press high-pressure gas into this intake chamber 37, so that the intake chamber 37 has a longer time to press high-pressure gas to achieve the highest air compression ratio. The use of this oil delivery channel structure can only rely on the engine's own oil self-circulation method and omit the installation of an oil pump, thereby reducing the structure and weight of the engine and reducing the causes of engine failure.

[0127] The rotary engine can use a method in which each rotary combustion chamber works sequentially during one rotation, or a method in which each rotary combustion chamber does not work completely during one rotation and each rotary combustion chamber works at intervals during multiple rotations. Figure 8a , Figure 8b , Figure 8c The rotating combustion chambers of the seven-tooth lobe gear engine of the present invention are shown to illustrate various modes of operation:

[0128] Figure 8a , Figure 8b , Figure 8c The combustion chamber of the seven-tooth lobe gear engine of the present invention can have six working modes:

[0129] Method 1: Work is performed seven times per revolution (i.e. the combustion chamber works in a cycle of 1-2-3-4-5-6-7-1);

[0130] Method 2: Work is performed at intervals of one combustion chamber. Each combustion chamber works once every two revolutions, and works three to four times per revolution. Electronic control is required to work at intervals of one combustion chamber. (i.e., the combustion chambers work in sequence 1-3-5-7-2-4-6-1);

[0131] Method 3: Work is performed at intervals of two combustion chambers. Each combustion chamber works once every three revolutions, and works two to three times per revolution. Electronic control is required to work at intervals of three combustion chambers. (i.e., the combustion chambers work in sequence 1-4-7-3-6-2-5-1);

[0132] Method 4: Work is performed at intervals of three combustion chambers. Each combustion chamber works once every four revolutions and works twice per revolution. Electronic control is required to jump three combustion chambers to work. (i.e. the combustion chambers work in sequence 1-5-2-6-3-7-4-1);

[0133] Method 5: Work is performed in four combustion chambers at intervals, each combustion chamber works once in four circles, and work is performed twice in each circle. (i.e., the combustion chambers work in sequence 1-6-4-2-7-5-3-1);

[0134] Method six: work is performed every five combustion chambers, and each combustion chamber works once in seven circles, and work is performed once in each circle. (i.e., the combustion chambers work in sequence 1-7-6-5-3-6-4-2-1).

[0135] The rotary combustion chamber uses various working modes. When different power output or idling operation is required, electronic control methods can be used (for example, synchronous rotary cam touch type or synchronous rotary hole photoelectric type can be installed on the rotating shaft to synchronously position each combustion chamber to rotate to Figure 8a and Figure 8b A small electrical signal is sent out at a time to control the interval operation of the fuel injectors and spark plugs in different combustion chambers. Fig.21a and Figure 21b The synchronously rotating fuel hole 93, the synchronously rotating spark plug hole 94, the fuel photoelectric transmitter 95, the fuel photoelectric receiver 96, the spark plug photoelectric transmitter 97 and the spark plug photoelectric receiver 98 realize the above-mentioned six combustion chamber working modes, thereby achieving the purpose of improving fuel thermal efficiency, saving fuel and improving economy.

[0136] The first method is the most wasteful of fuel. Due to the untimely replenishment of fresh air, the fuel will be discharged before it is fully burned. In addition, the high-pressure combustion gas leaked from the combustion chamber in front of it may enter the fuel injection of the next rotating combustion chamber, causing this combustion chamber to burn in advance and cause the cylinder to explode. The second, third and fourth methods are relatively economical and long-term working methods. Since each combustion chamber works in intervals, the auxiliary combustion start chamber, each single combustion chamber and the tooth head of the lobe gear can be fully cooled, so that the combustion chamber will not be overheated and easily damaged locally. At the same time, the working life of the most stressed lobe gear is extended, and the maintenance time of the machine is reduced. At the same time, the interval work of the combustion chamber can replenish new air from the combustion chamber below the interval that does not work to the auxiliary combustion start chamber, so that the high-pressure combustion gas that is not fully burned when the next interval combustion chamber works can be fully burned and work in the auxiliary combustion start chamber. The fifth and sixth working methods can be used when idling. The above working mode can be manually switched by the operator at any time according to the current situation by the central electronic controller, so that the seven-tooth blade gear rotary combustion chamber engine of the present invention can have different working modes. The use of multiple working modes can also replace part of the gearbox function to achieve the function of the gearbox, so that the gearbox no longer needs to be set with multiple gears, or it can completely replace the gearbox function and only rely on different combustion chamber working modes to adjust the speed and output power.

[0137] In use, from Figures 10 to 13 It can be seen that wheels can be directly installed at both ends of the leaf-shaped rotating piston head gear shaft 21 or the rotating combustion chamber shaft 22. The gear shaft is the wheel shaft that directly drives the wheel to rotate. As long as the central electronic controller controls the auxiliary combustion starting chamber 18 and each combustion chamber to work in different modes or not work, the wheels can produce different speeds or remain stationary, thereby completely eliminating the need for component structures such as a gearbox, a transmission shaft, a universal joint and a power shaft, greatly simplifying the locomotive components; a wheel can also be installed at one end of the leaf-shaped rotating piston head gear shaft 21 or the rotating combustion chamber shaft 22, and one of the two leaf-shaped gear shafts can be directly used as a motorcycle wheel shaft, so that the engine of the present invention can be used as the optimal power for transportation tools such as bicycles, four-wheeled vehicles and motorcycles.

[0138] It can be seen that the electronic control circuit of the rotating combustion chamber using the leaf-shaped gear with an odd number of teeth is simple. It only needs to count and control the operation of the injectors and spark plugs in each combustion chamber at regular digital intervals to execute the corresponding six working modes. The electronic control circuit of the rotating combustion chamber using the leaf-shaped gear with an even number of teeth will be slightly more complicated than that of the leaf-shaped gear with an even number of teeth. It is necessary to consider that the rotating combustion chamber of the leaf-shaped gear with an even number of teeth cannot be controlled at regular intervals.

[0139] from Figures 8a to 13It can be seen from the three-dimensional diagram of the seven-tooth lobe gear rotary combustion chamber engine of the present invention that the space of the inner wall of the middle cylinder body of the auxiliary combustion starting chamber is enlarged, and a fuel injector and a spark plug are installed on the inner wall of the middle cylinder body. The central controller controls the above-mentioned fuel injector and spark plug to spray fuel into the auxiliary combustion starting chamber and ignite it, so that the gas combustion drives the two seven-tooth lobe gears to rotate relative to each other, driving the entire seven-tooth lobe gear engine to rotate and start, thereby driving the lobe-shaped rotary piston head gear No. 1 tooth head and the rotary combustion chamber No. 8 combustion space of the rotary combustion chamber 3 to rotate and that is, Figure 8a When the position is shown, if the second working mode is adopted, that is, "one combustion chamber works every other time, each combustion chamber works once every two turns, and works three times every turn, and electronic control is required to work one combustion chamber at a time. (That is, the combustion chambers work in sequence 1-3-5-7-2-4-6-1)", the synchronous rotating cam 73 installed on the leaf-shaped rotary piston head gear shaft 21 also rotates synchronously to Figure 9a The synchronously rotating cam fuel No. 1 convex touch point 81 touches the synchronously rotating cam toucher 74 upper row of toucher fuel injector control contacts, and the electrical signal generated by the toucher fuel injector control contacts is transmitted to the central electronic controller through the circuit, and the central electronic controller controls the nozzle 13 installed in the combustion space of the No. 1 combustion chamber 8 to spray fuel. When the gear rotates to Figure 8b When the piston head is in the position, the synchronous rotating cam 73 mounted on the leaf-shaped rotating piston head gear shaft 21 rotates synchronously to Figure 9b1-Figure 9b4 In the middle position, the synchronous rotating cam spark plug No. 1 convex touch point 82 touches the contactor injector control contact of the lower row of the synchronous rotating cam contactor 74, and the electrical signal generated by the contactor spark plug control contact is transmitted to the central electronic control room through the circuit for reception, and the central electronic control room then controls the spark plug 14 installed in the combustion space of the No. 1 combustion chamber 8 to ignite the mixed compressed gas of fuel and air, and the mixed compressed fuel gas begins to explode and burn and pushes the tooth head of the leaf-shaped rotating piston head gear and the teeth and gears in the rotating combustion chamber 3 to accelerate the rotation to do work. When the No. 1 tooth head of the leaf-shaped rotating piston head gear 1 and the teeth and gears in the rotating combustion chamber 3 rotate to Figure 8cWhen the separation begins, the explosive combustion gas rushes into the auxiliary combustion starting chamber 18 from the teeth and the separation opening position from the combustion space of the No. 1 combustion chamber 8, continues to mix with the oxygen stored in the auxiliary combustion starting chamber 18, and continues to burn fully while continuing to push the gears on both sides to rotate and do work. In the auxiliary combustion starting chamber 18, the exhaust gas that has completed the explosion and combustion is sealed and rotated by the high-pressure airtight chambers 19 on both sides that continue to rotate. Since the high-pressure exhaust gas in the high-pressure airtight chamber 19 is still sealed, even if there is physical contact between the gear top and the side wall of the intermediate cylinder body 36 from time to time, there is a gap and a small amount of gas leaks, two high-pressure airtight chambers 19 can be formed on each side (the leaf-shaped rotating piston head gear 1 on the left and the combustion space of the No. 1 combustion chamber 8 on the right). Even if it leaks from the first high-pressure airtight chamber 19, it will be blocked in the second high-pressure airtight chamber 19. At the same time, since the gear rotates very fast, the high-pressure gas leaks for a very short time, thereby playing a perfect air sealing role for the combustion space of the No. 1 combustion chamber 8 and the auxiliary combustion starting chamber 18 that do work, so that the combustion high-pressure gas that does work can be utilized to push the gears to rotate without leaking too much waste.

[0140] Since the aforementioned second working mode is adopted, the No. 2 tooth head of the next leaf-shaped rotating piston head gear 1 and the combustion space of the second combustion chamber single zone of the rotating combustion chamber 3 rotate over the teeth, and at the same time, the No. 2 protrusion point of the synchronous rotating cam 73 row of fuel touches the synchronous rotating cam contactor 74, and the electrical signal generated is transmitted to the central electronic controller through the circuit for reception. The central electronic controller does not send a signal to the fuel nozzle and spark plug of the second single zone of the combustion chamber of the rotating combustion chamber 3 according to the second working mode program, so that the latter two do not work, thereby achieving the second working mode of one combustion chamber apart. At the same time, since there is no combustion work in the interval combustion chamber, new air, that is, oxygen, is brought into the auxiliary combustion starting chamber.

[0141] Then, the high-pressure airtight chambers 19 continuously formed on both sides of the two aforementioned leaf-shaped gears rotate to the leaf-shaped rotating piston head gear high-pressure air channel 31 and the rotating combustion chamber high-pressure air channel 32 respectively, and the high-pressure burned exhaust gas in the two high-pressure airtight chambers 19 is sprayed into the air from the channels or discharged into the air inlet of the turbocharger and then discharged into the air, so that the air pressure in the two high-pressure airtight chambers 19 is consistent with the external space. At the same time, the space after the exhaust gas is discharged in the high-pressure airtight chamber 19 originally surrounded by the tooth head of the left leaf-shaped rotating piston head gear No. 1 continues to rotate counterclockwise to the leaf-shaped rotating piston head gear cooling air inlet 38. Due to the centrifugal action of the gear, fresh air enters, and at the same time, the leaf-shaped rotating piston head gear cooling air outlet 33 exhausts air, thereby completing the exhaust gas on the left and then replacing the fresh air while cooling and taking away the heat after the entire left leaf-shaped rotating piston head gear 1 does work; the same is true for the right The combustion space of combustion chamber No. 1 8 of the rotary combustion chamber 3 then rotates clockwise to the rotary combustion chamber cooling air outlet channel 34, and a centrifugal fan is installed in the rotary combustion chamber cooling air outlet channel 34. Air is taken in through the air inlet of the centrifugal fan, and the high-speed rotation of the centrifugal fan forces air in and discharges the unexhausted exhaust gas in the combustion space of combustion chamber No. 1 8 of the rotary combustion chamber 3, and cools the various components of the combustion space of combustion chamber No. 1 8 of the rotary combustion chamber 3. This is because the combustion chamber of the rotary combustion chamber 3 is closed by the front circular clamping plate 23 of the rotary combustion chamber and the rear circular clamping plate 24 of the rotary combustion chamber, and the air inlet cannot be opened on the front cylinder side plate 11 and the rear cylinder side plate 12 like the leaf-shaped rotary piston head gear 1 on the left. Of course, the centrifugal fan can be used instead of the high-pressure air blown out by the turbine blower to directly blow into the combustion space of combustion chamber No. 1 8 of the rotary combustion chamber 3 like a centrifugal fan.

[0142] The two lobe gears rotating in opposite directions rotate into the auxiliary combustion starting chamber without doing work but only bringing in fresh air at the No. 2 tooth head of the aforementioned lobe-shaped rotary piston head gear 1 and the No. 2 single-zone combustion space of the combustion chamber of the rotary combustion chamber 3, then the No. 3 tooth head of the lobe-shaped rotary piston head gear 1 and the No. 3 single-zone combustion space of the combustion chamber of the rotary combustion chamber 3 continue to align, and the central electronic controller controls the repeating of the No. 1 tooth head of the lobe-shaped rotary piston head gear 1 and the No. 1 combustion chamber 8 combustion space of the rotary combustion chamber 3 to complete the next working process of injection-compression-ignition-combustion-working, so that the two lobe gears are continuously pushed to rotate in the opposite direction at high speed at intervals, and at the same time, the lobe-shaped rotary piston head gear 1 is driven by the auxiliary gear 41 on the lobe-shaped rotary piston head gear shaft and the auxiliary gear 42 on the rotary combustion chamber shaft, and the lobe-shaped rotary piston head gear shaft 21 is used as the power output shaft to output power, and of course, it can also be reversed by the rotary combustion chamber shaft 22 (Main rotating combustion chamber shaft) is used as a power output shaft to output power, and can also be connected to another main power shaft through the above two shafts using different connection methods such as gears and or clutches to output power.

[0143] By opening the lobe-shaped rotary piston head gear cooling air inlet 38 on the front and rear cylinder side plates, the entire lobe-shaped rotary piston head gear 1 can be fully cooled while the combustion exhaust gas entrained between the lobe-shaped rotary piston head gears 1 is discharged and fresh air is input.

[0144] In each individual combustion chamber of the rotary combustion chamber 3, a fuel injector 13 and a spark plug 14 are installed at the same time, so that the problem of easy wear of the lobe-shaped rotary piston head gear 1 caused by installing it on the side of the tooth head of the lobe-shaped rotary piston head gear 1 is solved.

[0145] A pair of identical leaf-shaped rotating piston head gear shafts, auxiliary gears 41 on the leaf-shaped rotating piston head gear shafts and auxiliary gears 42 on the rotating combustion chamber shafts are installed on the leaf-shaped rotating piston head gear shafts 1 and the leaf-shaped rotating combustion chamber gear shafts (main rotating combustion chamber shafts) outside the front and rear cylinder side panels. Due to the common gears of the same size and shape, when the leaf-shaped rotating piston head gear shaft 1 and the leaf-shaped rotating combustion chamber gear shaft are driven to rotate by the two leaf-shaped gears, this pair of common gears also synchronize their teeth and rotations. At the same time, when the two leaf-shaped gears are driven to rotate by the combustion chamber gas, the torque of the two leaf-shaped gears is transmitted to the pair of common gears through the leaf-shaped rotating piston head gear shaft and the leaf-shaped rotating combustion chamber gear shaft, and the rotational torque is synchronously transmitted to the power output shaft to output the rotational power, which is equivalent to increasing the length of the two leaf-shaped gear teeth and line 17, thereby reducing the wear of the tooth heads of the two leaf-shaped gears and extending the service life of the two leaf-shaped gears.

[0146] Through the above measures, adding an auxiliary gear 41 on the leaf-shaped rotary piston head gear shaft can solve the problem that gear parts are easy to wear and need frequent maintenance and replacement; at the same time, adding an auxiliary combustion starting chamber fuel injector 51 and an auxiliary combustion starting chamber spark plug 52 in the auxiliary combustion starting chamber 18 also makes the engine of the present invention not need auxiliary equipment (starting motor), reduces the weight of the engine, and the power of the battery does not need to be too large. The traditional engine needs a starting motor to drive the initial rotation and an oil pump, so a high-power battery is required; in addition, two air intake openings, namely the leaf-shaped rotary piston head gear cooling air intake 38, are opened on the front and rear cylinder side panels. These two air intake openings can be directly connected to the high-pressure air outlet of the aforementioned gas boosting equipment so that the entire leaf-shaped rotary piston head gear 1 can be fully cooled and exhaust gas is discharged to input fresh air, or one of the two leaf-shaped rotary piston head gear cooling air intakes 38 can be directly changed to a leaf-shaped rotary piston head gear cooling outlet channel, and the two openings can be used as an inlet and an outlet for air to accelerate the cooling and exhaust of the leaf-shaped rotary piston head gear, and there is no need to set a leaf-shaped rotary piston head gear cooling outlet channel.

[0147] Fifth embodiment

[0148] This embodiment provides an integrated tandem lobe gear rotary dual combustion chamber engine.

[0149] like Figures 14a to 17 As shown, an embodiment of a rotor engine with two pairs of seven teeth and a double-wheel rotary combustion chamber, Fig.14a , Fig.14b , Fig.14c For the schematic diagram, Fig.15 It is a three-dimensional schematic diagram of the present invention.

[0150] from Fig.14a , Fig.14b , Fig.14c Three pictures to Fig.17 It can be seen from the figure that the fifth embodiment has two engines of the fourth embodiment connected in series, and the two leaf-shaped rotary piston head gears 1 and the two leaf-shaped rotary combustion chamber gears respectively share the same leaf-shaped rotary piston head gear shaft 21 and the same rotary combustion chamber shaft 22 (main rotary combustion chamber shaft) (it can also share only one of the shafts, as can be seen in FIG. Fig.23 and Fig.24 The upper and lower series connection only shares the same rotary combustion chamber shaft 22. When two engines of the fourth embodiment are connected in series, the front cylinder body side plate 11 of one engine and the rear cylinder body side plate 12 of the other engine that are attached together are changed into an integrated intermediate cylinder body partition plate 83. The rotary combustion chamber circular clamping plate hole sockets 25 are respectively opened on both sides of the intermediate cylinder body partition plate 83. The rotary combustion chamber circular clamping plate hole sockets 25 can just accommodate the rotary combustion chamber front circular clamping plate 23 and the rotary combustion chamber rear circular clamping plate 24 of the upper and lower engines to rotate at high speed in the holes; different from the fourth embodiment, from Fig.14a , Fig.14b , Fig.14c As can be seen from Figure 8, the space in the two auxiliary combustion starting chambers 18 of the present invention is expanded upward accordingly, and a circular hole is opened at the position of the auxiliary combustion starting chamber 18 on the middle cylinder body partition 83 in the upper expanded space as an auxiliary combustion starting chamber air passage 84 to make the upper and lower auxiliary combustion starting chambers 18 communicate with each other. The injector 13 and the spark plug 14 are installed on the auxiliary combustion starting chamber air passage 84, which can directly replace the auxiliary combustion starting chamber injector 51 and the auxiliary combustion starting chamber spark plug 52 in the auxiliary combustion starting chamber 18.

[0151] Fig.15It can be seen from the figure that it is basically the same as the previous embodiment, except that it is equal to the series engine of the double set of leaf-shaped rotary piston head gears 1 and the rotary combustion chamber 3 composed of two engines in series as described in the previous column. The series engine of the double set of rotary combustion chambers 3 shares a leaf-shaped rotary piston head gear shaft 21 and a rotary combustion chamber shaft 22). At the same time, the original two front cylinder side plates 11 and rear cylinder side plates 12 between the two series engines are replaced with a middle cylinder body partition 83, and the two sides of the middle cylinder body partition 83 are respectively dug with rotary combustion chamber circular clamping plate holes The socket 25 can accommodate the two rotating combustion chamber front circular clamps 23 and the rotating combustion chamber rear circular clamps 24 to rotate in this leaf-shaped rotating combustion chamber circular clamp hole socket 25; a circular hole channel (that is, the auxiliary combustion starting chamber inter-air passage 84) is opened at the position of the auxiliary combustion starting chamber 18 enlarged by the two engines in the middle cylinder body partition 83, and the auxiliary combustion starting chamber inter-air passage 84 is installed with a fuel injector 13 and a spark plug 14 on the wall to replace the auxiliary combustion starting chamber fuel injector 51 and the auxiliary combustion starting chamber spark plug 52, which can be used for starting and rotating the entire engine.

[0152] However, this type of tandem rotor engine uses a shared partition plate 83 in the middle cylinder body, which can easily cause the partition plate 83 in the middle cylinder body to overheat and deform, and also affect the working environment of the leaf-shaped gears in this area, making the two leaf-shaped gears have a short life and are prone to wear.

[0153] Combine the following Figures 15 to 17 From the internal 3D structural diagram, it can be seen that the working process of this series double seven-tooth leaf-shaped tooth double-wheel rotary combustion chamber rotor engine is basically consistent with the working process of the fourth embodiment, except that one more set of rotary combustion chambers 3 are involved in the work, and the two engines can be synchronously controlled to work synchronously in the same way as the fourth embodiment.

[0154] exist Fig.15 In the figure, it can be seen that the single engines are separated on both sides by the partition 83 in the middle cylinder body. The leaf-shaped rotary piston head gears 1 in the two engines are installed on the same leaf-shaped rotary piston head gear shaft 21, and the rotary combustion chambers 3 in the two engines are installed on the same rotary combustion chamber shaft 22, and the installation angles are completely consistent.

[0155] Fig.14a The combustion chamber of the seven-tooth lobe gear engine described in FIG8 can have the same six operating modes;

[0156] The double series seven-tooth lobe gear rotary combustion chamber engine of the present invention also has a working mode different from the single rotary combustion chamber of the first to fifth embodiments described above:

[0157] Since it is composed of two auxiliary combustion starting chambers 18 connected up and down, the combustion chambers on the two rotating combustion chambers 3 can be electronically controlled to work at different times. For example, when the No. 1 combustion chamber on the upper rotating combustion chamber 3 is working, the No. 1 combustion chamber on the lower rotating combustion chamber 3 does not spray oil or ignite. After the spark plug of the No. 1 combustion chamber on the upper rotating combustion chamber 3 ignites the fuel gas and explodes and burns, it rotates to a certain angle to Fig.14c Position, the No. 1 combustion chamber gear and the seal are opened and the explosion combustion gas rushes into the upper auxiliary combustion starting chamber 18 and rushes into the lower auxiliary combustion starting chamber 18 through the auxiliary combustion starting chamber inter-chamber air passage 84. The unburned high-pressure fuel gas that rushes in and the oxygen in the air without fuel gas in the lower auxiliary combustion starting chamber 18 continue to fully and completely burn. The fully burned high-pressure gas in the upper and lower auxiliary combustion starting chambers 18 continues to drive the upper and lower two pairs of lobe gears to rotate, driving the shared lobe-shaped rotary piston head gear shaft 21 and the rotary combustion chamber shaft 22 to rotate and output power. At the same time, the auxiliary gears on the lobe-shaped rotary piston head gear shafts respectively installed on the lobe-shaped rotary piston head gear shafts 21 and the rotary combustion chamber shaft 22 The wheel 41 and the auxiliary gear 42 on the rotating combustion chamber shaft also jointly drive the leaf-shaped rotating piston head gear shaft 21 and the rotating combustion chamber shaft 22 to rotate, thereby reducing the wear of the two pairs of leaf-shaped rotating piston head gears 1 and the leaf-shaped rotating combustion chamber gears 2; since the combustion chambers on the upper and lower rotating combustion chambers 3 are all operated by fuel injection and ignition with one combustion chamber interval between them, the position of combustion chamber No. 1 on the lower rotating combustion chamber 3 is relative to the position of combustion chamber No. 2 on the upper rotating combustion chamber 3, so when combustion chamber No. 1 on the lower rotating combustion chamber 3 is operating by fuel injection and ignition, combustion chamber No. 2 on the upper rotating combustion chamber 3 is not operating, and the explosion combustion gas rushes into the upper auxiliary combustion starting chamber 18 and drives the engine power shaft to rotate and output power.

[0158] This upper and lower groups of combustion chambers work alternately, and the upper or lower combustion chambers can work separately with one or more combustion chambers separated, so that the mixed combustion gas that is not completely burned in the rotating combustion chamber 3 and the oxygen in the upper and lower auxiliary combustion starting chambers 18 can be fully and completely burned. The connection between the upper and lower auxiliary combustion starting chambers 18 is equivalent to increasing the space of the auxiliary combustion starting chamber 18, so that the fuel combustion time is prolonged and the combustion gas is not easily discharged quickly by the high-speed rotating gears. The high-pressure gas when fully burned in the upper and lower auxiliary combustion starting chambers 18 can also continuously push the upper and lower groups of gears to rotate and do work, thereby improving the fuel combustion efficiency.

[0159] This series-connected double seven-tooth lobe gear rotary combustion chamber engine does not necessarily require the lobe gears of the two sets of lobe gear rotary combustion chambers to be identical. It can also be that two sets of lobe gear rotary combustion chambers with different numbers of teeth, different tooth top circles, different tooth widths, etc. are connected in series.

[0160] like Figures 14a to 17As shown in the stereogram, the tandem double seven-tooth blade gear rotary combustion chamber engine can be seen that, through the above measures, the two connected auxiliary combustion start chambers 18 and the upper and lower rotary combustion chambers 3 alternately work in an interval manner to solve the problem that the auxiliary combustion start chamber 18 is not large enough and the explosive combustion gas is discharged at high speed before being fully burned. At the same time, if a synchronous rotating cam 73, a synchronous rotating cam contactor 74 and a central electronic controller of the engine are added, the stability and power output retention of the entire tandem double seven-tooth blade gear rotary combustion chamber engine can be improved, which can meet the needs of some special working environments (such as helicopter engines).

[0161] Sixth embodiment

[0162] This embodiment provides a parallel-type vane-shaped gear rotary dual-combustion chamber fuel engine.

[0163] like Figures 18a to 22 As shown, an embodiment of a rotor engine with two pairs of seven teeth and a double-wheel rotary combustion chamber, Fig.18a , 18b , 18c is the state diagram of different rotation positions, and is the principle diagram. Figure 20 to Figure 22 It is a three-dimensional schematic diagram of the present invention.

[0164] from Fig.18a , 18b 、18c three pictures to Fig. 22 It can be seen from the figure that the difference between the sixth embodiment and the fifth embodiment is Figure 5 The first embodiment is that two pairs of leaf-shaped gears are connected in series along the upper and lower mounting shafts, while the two pairs of leaf-shaped gears described in the sixth embodiment are connected in parallel on a plane, which is equivalent to an auxiliary combustion starting chamber air passage 84 being opened between the two auxiliary combustion starting chambers 18 of the two fourth embodiment engines. The two fourth embodiment engines are combined on a plane, and the parallel double seven-tooth leaf-shaped gear rotary combustion chamber engines share the front cylinder side plate 11 and the rear cylinder side plate 12 and the middle cylinder body partition 83. An auxiliary combustion starting chamber air passage 84 is opened on the middle cylinder body partition 83 to connect the upper and lower auxiliary combustion starting chambers 18 on the plane. A fuel injector and a spark plug are installed on the wall of the auxiliary combustion starting chamber air passage 84, which can be used for starting and rotating the entire engine. The sixth embodiment of the present invention does not share the leaf-shaped rotary piston head gear shaft 21 and the rotary combustion chamber shaft 22.

[0165] Figures 18a to 22 As shown in the figure, it can be seen that the working mode is exactly the same as the previous embodiment. The upper and lower combustion chambers use this upper and lower alternating working mode, but the axial upper and lower alternating interval working mode is changed to the plane front and back alternating interval working mode. Fig. 20 and Fig. 22It can be seen that two pairs of power output gears 100 (the gears can also be ratchets) are respectively installed on two leaf-shaped rotating piston head gear shafts 21 and two rotating combustion chamber shafts 22 on both sides of the entire outer shell, and the rotation direction of the power output gears 100 on one side is consistent.

[0166] from Figures 18a to 20 It can be seen that the high-pressure air passage 31 of the lobe-shaped rotary piston head gear is directly enlarged, and the cooling air outlet passage 33 of the lobe-shaped rotary piston head gear is cancelled. The high-pressure air passage 31 of the lobe-shaped rotary piston head gear and the cooling air inlet 38 of the lobe-shaped rotary piston head gear simultaneously play the functions of discharging high-pressure combustion gas, cooling gears and ventilating. The cooling air outlet passage 33 of the lobe-shaped rotary piston head gear can also be cancelled without enlarging the high-pressure air passage 31 of the lobe-shaped rotary piston head gear. The two lobe-shaped rotary piston head gear cooling air inlets 38 at symmetrical positions on the two front cylinder side plates 11 and the rear cylinder side plates 12 are directly blown in air from one port for cooling, and the exhaust gas is discharged from the lobe-shaped rotary piston head gear cooling air inlet 38 on the other side.

[0167] This parallel double seven-tooth lobe gear rotary combustion chamber engine does not necessarily require the lobe gears of the two sets of lobe gear rotary combustion chambers to be consistent. It can also be that two sets of lobe gear rotary combustion chambers with different numbers of teeth, different tooth top circles, different tooth widths, etc. are connected in parallel.

[0168] from Figures 18a to 22 It can be seen from the parallel double seven-tooth blade gear rotary combustion chamber engine of the present invention shown in the stereoscopic diagram that through the above measures, the two communicating auxiliary combustion starting chambers 18 and the alternating interval working method of the upper and lower rotary combustion chambers 3 solve the problems that the auxiliary combustion starting chamber 18 is not large enough and the explosive combustion gas is discharged at high speed without being fully burned; at the same time, if a synchronous rotating hole wheel 91, a synchronous rotating hole wheel photoelectric transmitter and receiver 92 and a central electronic control center of the engine are added in another figure, the stability and power output retention of the entire parallel double seven-tooth blade gear rotary combustion chamber engine of the present invention can be improved, which can meet the requirements of some special safe working environments (such as helicopter engines).

[0169] Seventh embodiment

[0170] This embodiment provides a series-parallel type leaf-shaped gear rotating multi-combustion chamber fuel engine.

[0171] Figure 23 to Figure 24 Another preferred embodiment of the present invention is also an embodiment of a three-pair seven-tooth lobe gear rotating three-combustion chamber fuel engine. Figure 23 to Figure 24 It is a two-viewing perspective stereoscopic schematic diagram of the present invention.

[0172] from Fig.23 and Fig.24It can be seen from the bottom of the stereoscopic diagram that there is a sixth embodiment of the parallel lobe gear rotary dual combustion chamber fuel engine, and an engine of the fourth embodiment is connected in series to a pair of teeth and a gear shaft constituting a rotary combustion chamber in this parallel lobe gear rotary dual combustion chamber fuel engine. The auxiliary combustion starting chamber 18 of the upper engine and the pair of teeth at the lower part of the same gear shaft and the auxiliary combustion starting chamber 18 in the rotary combustion chamber are connected by an auxiliary combustion starting chamber inter-ventilation pipe 85 (which can be a direct connection or a curved connection), so that the two engine combustion chambers connected in series from top to bottom constitute the same series lobe gear rotary dual combustion chamber fuel engine as the fifth embodiment. The slight difference from the fifth embodiment of the series lobe gear rotary dual combustion chamber fuel engine is that the two single combustion chambers in series do not share a common intermediate cylinder body partition plate 83, which is different from the fifth embodiment of the series lobe gear rotary dual combustion chamber fuel engine. Another difference between the coupled type and the coupled type is that the engines connected in series only share the rotating combustion chamber shaft 22, and do not share the leaf-shaped rotating piston head gear shaft 21. The advantage is that the rotating combustion chamber shaft 22 can be used directly as the wheel shaft, so that the engine can be installed on both sides of the wheel at the same time. Of course, it is also possible to only share the leaf-shaped rotating piston head gear shaft 21 and not share the rotating combustion chamber shaft 22, and use the leaf-shaped rotating piston head gear shaft 21 directly as the wheel shaft. The advantage of this method is that the engine can be installed on both sides of the axle. The aforementioned fourth invention example can also use one shaft as the wheel shaft, but the engine is installed on one side. Since the two single-combustion chamber engines are separated by a distance, the advantage is that the heat dissipation performance is good and the parts maintenance is convenient. At the same time, in order to maintain the advantages of the series combustion chamber (increasing the space size of the auxiliary combustion starting chamber 18), the auxiliary combustion starting chamber inter-air duct 84 on the fifth embodiment is changed to Fig.23 and Fig.24 The auxiliary combustion starting chamber ventilation pipe 85 on the auxiliary combustion starting chamber is connected in series with the auxiliary combustion starting chambers 18 on the two single combustion chambers, so that two types of engines, series and parallel, are combined in one engine as a whole, and can be used in series, parallel, mixed and other structural types.

[0173] For the convenience of drawing, each sub-group rotating combustion chamber shown in the example diagram of the present invention uses three pairs of the same seven-tooth lobe gears to rotate a three-combustion chamber fuel engine, but it is by no means limited to lobe gears with the same number of teeth or shape. Each group of lobe gears that make up the three combustion chambers can have a different number of teeth, different tooth diameters, different tooth widths, etc. The advantage is that a large tooth diameter can provide a large torque, and a large number of teeth can increase the output power by doing more work per circle. An increase in tooth width can increase the volume of the combustion space of each single combustion chamber and increase the output power. In this way, different sub-group rotating combustion chambers can be controlled to work in different working environments, and all sub-group rotating combustion chambers can work together as needed.

[0174] from Figure 23 to Figure 24It can be seen from the three-dimensional diagram of the series-parallel blade gear rotating multi-combustion chamber fuel engine of the present invention that, through the above measures, the three connected auxiliary combustion starting chambers 18 and the rotating combustion chamber 3 can adopt an alternating interval working method to further increase the combustion space of the auxiliary combustion starting chamber 18 and better solve the problem of sufficient combustion of the explosive combustion gas.

[0175] At the same time, a synchronously rotating hole wheel 91, a synchronously rotating hole wheel photoelectric transmitter and receiver 92 (a form of position trigger) and a central electronic controller of the engine are added to the figure. The use of dual backup working components (dual control components and multiple rotating combustion chambers) can improve the stability and power output retention of the entire series-parallel blade gear rotating multiple combustion chamber fuel engine, which can meet the needs of some special working environments (such as helicopter engines).

[0176] It can also be seen from the figure that since the power shaft 101 is on the side of the engine, a set of the same series-parallel leaf-shaped gear rotating multi-combustion chamber fuel engines of the present invention can be conveniently installed side by side on the other side, and by extending the length of the power shaft 101 and increasing the power shaft gear 102, various engines of the present invention can be further increased. At the same time, one to multiple combustion chamber engines of the present invention can also be connected in series on the two pairs of teeth in the aforementioned parallel leaf-shaped gear rotating dual-combustion chamber fuel engine and the gear shaft that constitutes the rotating combustion chamber. In this way, the number of the present invention can be conveniently increased as needed to increase the power of the entire engine; the power output gear 100 can also use a ratchet combined with an auxiliary combustion starting chamber intervent pipe 85 to add a high-pressure valve, so that the single leaf-shaped gear engine in series and parallel can close the high-pressure valve as needed or in the event of a fault, so that the engine of this power output gear 100 does not spray oil and ignite, so that the internal leaf-shaped gear stops rotating and does not participate in the output power work. The two leaf-shaped gear shafts of the engine can be conveniently connected to the power shaft 101 by means of teeth and or links, so that each single engine chamber can be conveniently removed from the power shaft 101, which improves the addition, installation or replacement of a single engine inside the entire engine, and the engine configuration in the power equipment can be configured according to temporary needs. The power shaft 101 can also be connected in series with two or more, and the series connection part can be connected by a clutch, and the non-working part of the combustion chamber can be made not to rotate by the clutch action, and the parallel connection part can be connected by ratchet teeth and can directly replace the function of the speed change gear box, and can arbitrarily control different multiple sub-rotating combustion chambers to work together or some sub-rotating combustion chambers to work or a certain sub-rotating combustion chamber to work alone according to the output torque and output power requirements. It can also reduce the auxiliary equipment of the leaf-shaped gear rotating combustion chamber engine of the present invention, and can also control various working modes of multiple combustion chambers according to the output power and combine the clutch control of the power shaft, so that the engine of the present invention can meet the power requirements of various types of engines, from small motorcycles and cars to large trucks, bulldozers and even helicopters.

[0177] Eighth embodiment

[0178] This embodiment provides a rotor engine with a rotating combustion chamber and a heterogeneous lobe gear.

[0179] Fig.25 , Fig.26a and Figure 26b Another embodiment of the present invention is a rotary combustion chamber rotor engine with a pair of more than two lobed gears with different numbers of teeth and different diameters, Fig.25 For the schematic diagram, Fig.26a and Figure 26b This is a simple schematic diagram of the three-dimensional structure of this type of engine;

[0180] Combining all the above embodiments, it can be seen that from a pair of lobe gears to any number of lobe gears, at least one lobe gear acts as a rotating closed gear (i.e., a rotating piston head gear), and at least another lobe gear (i.e., a rotating combustion chamber gear) and two circular clamps form a rotating combustion chamber, the tooth widths of all lobe gears are consistent, and each rotating combustion chamber can be closed by the lobe tooth head with the teeth thereof, and the fuel injector in the combustion chamber sprays fuel into the combustion chamber and is ignited by the spark plug in the combustion chamber to burn and perform work.

[0181] Although the principle of the rotary engine is the same as that of a general engine, and it has a four-program working cycle of intake, compression, explosion, and exhaust, the rotary engine consumes less power due to the fundamental difference in structure. The rotor of the engine is a whirling motion with fewer moving parts. The rotary engine completes intake, compression, explosion, and exhaust within a very small rotation angle. Its own special structure breaks through the mode of reciprocating engine suction, compression, explosion, and exhaust in one cylinder, and also solves the drawbacks of the Japanese Mazda rotary engine, such as high cost, high fuel consumption, easy wear and maintenance of parts, incomplete fuel combustion, burning oil, and high difficulty in manufacturing parts. It has the advantages of small size, light weight, simple structure, easy processing, and few vulnerable parts. In particular, its special auxiliary combustion starting chamber, rotating combustion chamber, high-pressure airtight chamber, air intake chamber, and unique structures that can be superimposed in series and parallel make the rotary engine of the present invention have sufficient fuel combustion to achieve high combustion thermal efficiency, can arbitrarily increase the number of rotating sub-combustion chambers and arbitrarily shut down the number of rotating sub-combustion chambers as needed, and greatly removes or simplifies various auxiliary equipment (such as starting motors, cooling devices, simplified gear transmissions, or even no gear transmissions).

[0182] The various lobe-shaped gear rotary combustion chamber rotor engines of the present invention are subjected to stress and wear only at the rotating shaft and the lobe-shaped tooth head, and the lobe-shaped tooth head position is more vulnerable. The present invention adopts various measures such as widening the tooth width of the lobe-shaped gear, increasing the auxiliary gear 41 on the lobe-shaped rotary piston head gear shaft and the auxiliary gear 42 on the rotary combustion chamber shaft, spacing the working mode of each combustion chamber and strengthening the heat dissipation and cooling of each lobe-shaped gear to reduce the lobe-shaped tooth head, which greatly reduces the problem of the vulnerability of the lobe-shaped tooth head and prolongs the service life of the lobe-shaped gear. The lobe-shaped gear rotary combustion chamber rotor engine of the present invention omits a series of parts such as the crankshaft, the traditional intake and exhaust valves, the starter motor, the gearbox and the power shaft, so the volume of the rotor engine can be very small. And because there is no reciprocating linear motion of the piston, it is almost only in circular motion and is not easy to generate vibration, so it runs more smoothly. The speed of the rotary engine is also significantly improved, and its advantages in improving power and fuel combustion thermal efficiency will play an important role in promoting the national economy and the national defense industry.

[0183] For ordinary technicians in the field of engines, it is very convenient to combine the technology used in existing traditional engines with the lobe gear engine of the present invention, such as using hollow manufacturing technology on the cylinder body and gears and other parts, and existing gas boosting equipment such as turbochargers and star piston engines, as well as gearbox technology, gear reducers and clutches can be added to the present invention without much thought. Without departing from the concept of the present invention, various combinations, deformations and improvements can be made, such as the combination of different lobe gear structures in various above-mentioned examples (such as different numbers of gears, different numbers of teeth, different tooth top circle diameters, series, parallel and mixed connections, etc.), etc., all of which belong to the protection scope of the present invention.
