Wheel internal combustion engine

Abstract

An internal combustion engine in the shape of a wheel or star with eight arms because it consists of 8 cylinders facing each other at the head, arranged in the form of a circle. This circle is divided into four main axes, and each two cylinders are extended on one axis. The end of each cylinder is opposite the end of the other. A small ring connects the end of all cylinders towards the center of the circle and It is called the inner ring. The beginnings of all cylinders are connected by a large ring, which is the circumference of the circle. This shape is called engine core. The entry and exit of the pistons is in the direction of the circumference of the circle. The direction of the piston travel in the power stroke is from the center outward in the direction of the circumference of the circle. All pistons are connected to non- articulated arms that end with free-moving pulleys that slide on slopes in the winding wall of the engine (zigzag frame) to change the direction of movement. We get the result of the final movement from the inner ring. And The cylinders are fed with the mixture from this same inner ring Through a hollow axle that passes inside this ring. The axle have 2 ports(one feed and one exhaust) meet the inner ring feed and exhaust ports during rotation in precise synchronization, which works to feed the cylinders with the mixture and exit the exhaust.

[0002] Internal combustion engineSummary of Invention

[0003] A four-stroke Internal combustion engine in the form of a wheel

[0004] The wheel engine operates with a completely different mechanism than the internal combustion engines currently in use. It works without (crankshafts or camshafts) and it works with (rotating cylinders, and floating pistons).

[0005] The wheel engine consists of a rotary engine core and there are 8 cylinders engraved inside it, and the engine core rotates on a fixed main X axis and is called the feed axis because the intake and exhaust channels are engraved inside it .The engine core is surrounded by a circular zigzag frame, This frame from the inside consists of 8 complete sine waves, and the outer diameter of this frame is a circle that represents the outer limits of the engine

[0006] The pistons connected to a non-articulated arm. At the end of this arm, a free-moving roller slides on the tops and bottoms of the zigzag circular frame. This roller transmits its movement to the piston arm and from there to the piston body causing Compression and unfolding of the piston between the TDC and BDC to convert the reciprocating movement of the piston to the rotational movement of the engine core .then the engine core transmits the required mechanical movement to the outside.

[0007] In the wheel engine, a many number of engine cores can be installed on the same main axis of the engine.

[0008] The 8-cylinder wheel engine works with a new system, as the cycle represents 360 degrees, and the journey of one cylinder in the 4 strokes requires 180 degrees, and at the same time the same cylinder can be operated again in the other half of the cycle. This means that it is possible toobtain a full revolution of the engine core through 8 power strokes if the cylinder is operated once. Or obtaining a complete rev of the engine through 16 power strokes in the case of running the cylinder twice in the cycle. Accordingly, every single power stroke or every 2 opposite power strokes can be obtained from them at 1 / 8 of a cycle by 45 degrees. It is called a wave step, meaning that it is possible to control the operation of the cylinders in two stages in the complete cycleTechnical Problem

[0009] many mechanical parts, which leads to a loss of a large amount of engine power

[0010] The engine size is large

[0011] It is not possible to control the operation of the number of cylinders operating inside the engine

[0012] The difficulty of maintenance and repairing internal engine parts

[0013] The size of the cooling and lubrication circuit is largeSolution to Problem

[0014] Reduced mechanical parts and thus lighter weight, reduced friction and

[0015] reduced energy loss

[0016] Improved volumetric efficiency by obtaining the same power in a smaller engine size

[0017] Controlling the operation of the number of cylinders as desired, which leads to energy savings

[0018] The engine is an upper and lower cover that can be removed and maintained easily and without disconnect the engine from the machine fixed in it

[0019] Very simple lubrication and cooling circuitsAdvantageous Effects of Invention

[0020] The movement of the reciprocating piston is carried out by means of a fixed, non-articulated arm connected to the piston, at the end of which a movable sliding roller is fixed on a zigzag circular frame

[0021] The generated movement that we get from the engine core as a result of the piston’s reciprocating movement gives greater torque, as all the moving mechanical parts (a sliding pulley, a non-articulated piston arm, guiding rollers, and the piston itself) have been exploited between the zigzag frame and the engine core as the length of the torque arm.

[0022] The cylinders are not fixed, but moving in a rotational movement with the engine core engraved inside.

[0023] The piston is floating, not fixed by movement ties.

[0024] Obtaining a power stroke from the number of 2 cylinders facing each other in the cycle at the same time, which allows dividing the volume of the cylinder and the piston by 2, which gives the advantages of small engine size, ease of cooling, saving fuel consumption, ease of repair and low cost

[0025] The use of one air supply inlet, one exhaust outlet, and one fuel injector, so that all cylinders rotate on them

[0026] The two outer covers of the engine are designed with the presence of direct ventilation holes on the body of the cylinders, so that the process of cooling the cylinders that are completely exposed to air takes place in an unprecedented direct manner. The cylinders used in current engines are buried inside the engine blockBrief description of the drawing of Figure No. 1 (engine structure)

[0027] Point No.lin the fiaureNo.1 shows the ziazaa circular frame and a recipe as follows

[0028] It is a large vicious circle whose diameter is the diameter of the motor and the diameter of the two covers, This frame is between the two engine covers, for example(Sandwich filling) so that its thickness is the distance between the two engine covers and It represents the outer borders of the engine, round and regular from the outside, and zigzags from the inside towards the center of the engine heart. It surrounds the heart of the engine, the cylinders, and the pistons. It is responsible for the shape of the reciprocating movement of the pistons resulting from the sliding of the pistons in a rotational manner on this frame.

[0001] This zigzag wave frame is in the form of a sine wave consisting of 8 waves connected in a row (4 waves at the top and 4 waves at the bottom). So that the difference between the top and bottom of this wave is the difference between the top dead center and the bottom dead center, i It is the piston stroke

[0002] Point No. 2 in Figure 1 shows the sliding rollers and a recipe as follows

[0003] They are rollers installed at the end of each piston arm that allow it to slide on the zigzag wave circular frame to achieve Piston travel

[0004] Point No. 3 in Figure 1 shows the piston arm and a recipe as follows

[0005] It is a non-articulated arm in the form of a metal rod. On both sides of this arm,

[0006] Longitudinal grooves are engraved to help the guide rollers slide inside. This arm begins with the piston head and sliding roller fixed at the end of this arm

[0007] Point No. 4 in Figure No. 1 shows the guide rollers and a recipe as follows

[0008] They are the 4 rollers that control the reciprocating movement of the piston,

[0009] installed vertically in the engine core at the top of the edge of each cylinder, 2 rollers on the right and 2 rollers on the left so that the piston arm can slide on it in its reciprocating motion.

[0010] These rollers also act as guides for the piston arm and move within grooves carved on either side of the piston arm

[0011] Point No. 5 in Figure 1 shows the rotating disk (engine core) and arecioe as follows

[0012] It is a uniformly round disc and the diameter of the disc equal to the engine diameter minus the two peaks of the circular wave frame, the two sliding rollers and the two guide rollers.

[0013] So engine heart diameter = engine diameter - two peaks of the wave circular frame - two sliding rollers - two guide rollers

[0014] As for the thickness of the disc, it is the same as the thickness of the zigzag circular frame

[0015] Inside this thickness, 8 cylinders are engraved, starting from the circumference of the circle and ending towards the center of the circle, so that the difference between the axis of each cylinder and the adjacent one is 45 degrees, and it is of appropriate length so that the ends of the cylinders do not meet together at the center of the disc.

[0016] The shape is similar in this description to a triangle cheese box (the cheese box is divided Inside it are 8 equal triangles, so we will dig a small cylindrical tunnel with a pencil at the base of each triangle that goes to the apex of the triangle of an appropriate length so that it does not touch the apex of the triangle or the side sides of the triangle This tunnel, which was drilled, represents the cylinders in which the pistons operate, so the cylinders are perpendicular to the center of the engine heart.

[0017] Point No. 6 in Figure 1 shows the cylinder and its recipe as follows

[0018] It is a cylindrical tunnel engraved in the heart of the rotary engine, and inside it holds the piston, where the internal combustion process takes place.

[0019] Point No. 7 in Figure No. 1 shows the main axial slot, and the recipe is as follows

[0020] It is a central hole in the middle of the engine core, through which the axial axe extending between the two outer engine covers passes and carries the rotating core on which its rotational movement moves.

[0021] Point No. 8 in Figure No. 1 shows the holes for the screws of the two outer covers and a recipe as follows

[0022] They are slots through which screws pass that connect the two outer covers of the engine, including the zigzag circular frame

[0023] Point No. 9. in the form of No. 1. the piston head, and the recipe is as follows

[0024] It is a cylinder with the same diameter as the cylinder, connected to the piston arm, and rings are engraved inside itFig.1Brief description of Figure 2

[0025] Point No. 1 in the form of No. 2 shows the piston head and the recipe is as follows

[0026] It is cylindrical in shape and has the same diameter as the cylinder with the piston arm, with tapers rings engraved inside it

[0027] Point No. 2 in the form of No. 2 showing the piston arm and a recipe as follows

[0028] It is a non-articulated arm in the form of a metal rod. On both sides of this arm, longitudinal grooves are engraved to help the guide rollers slide inside. This arm begins with the piston head and sliding roller fixed at the end of this arm

[0029] Point No. 3 in Figure 2 shows the grooves of the piston arm and a recipe as follows

[0030] It is a channel grooved along the piston arm on both sides for the guide rollers to slide inside

[0031] Point No. 4 in Figure 2 shows sliding rollers and a recipe as follows

[0032] They are rollers installed at the end of each piston arm that allow it to slide on the zigzag wave circular frame to achieve the piston's stroke.

[0033] Point No. 5 in Figure No. 2 shows the installation of sliding rollers, and a recipe is as follows

[0034] It is an X-mounted sliding roller with piston rodFig.2

[0035] Brief description of Figure 3

[0036] Point No. 1. 2. 3. and 4 in Figure No. 3 showing the rotation of the sliding rollers on points (A & B & C & D) in the zigzag circular frame. and the recipe is as follows

[0037] When sliding roller No. 1 is at point A, piston No. 1 is at top dead center and the mixture is compressed, and by giving the spark of fire, the power stroke occurs, and as a result of the power stroke, the piston pushes with the sliding pulley, so pulley No. 1 slides from point A to point B, so we get a change in the position of the engine core by 45 rotational degrees, because the piston arm is linked to the rotating engine core through the guide rollers When piston No. 1 reaches point B, the cylinder is still filled with exhaust This change in the position of the engine core also results in the movement of the piston pulley No. 2 from point H to point A, and the compression stroke of piston No. 2 occurs

[0038] We call this movement in the engine core, as it carries a change in the movement of the pistons from one point to another by step, and this is the end of step number 1

[0039] Step No. 2 is produced by giving a spark of combustion to piston No. 2, creating the power stroke, so step No. 2 is generated, causing a change of 45 degrees to turn the engine with its cylinders and pistons inside, which are as follows

[0040] The piston sliding pulley No. 2 moves due to the power stroke sliding from point A to point B, and the piston sliding roller No. 1 moves from point B to point C, and the piston moves in it to the top dead center to expels the exhaust with the exhaust valve open In the same step, all sliding rollers move by 45 degrees Including piston No. 3 moves from point H to point A, achieving a new compression stroke, which is the end of step No. 2

[0041] Step No. 3 is produced by giving the spark of combustion at point A to piston No. 3. The power stroke occurs and step No. 3 is generated. In this step, the sliding roller No. 3 moves due to the power stroke from point A to point B (Piston No. 3 power stroke)The piston sliding roller No. 2 moves from point B to point C, and the piston moves in it to the top dead center under pressure to empty the exhaust with the exhaust valve opened (pistonNo. 2 exhaust stroke) and in it the piston sliding roller No. 1 moves from point C to point D Piston No. 1 descends, generating a vacuum in the intake stroke (Piston No. 1 in the intake stroke)

[0042] The intake stroke takes place by means of the pulling intake bracket installed on the zigzag circular frame, which in turn attracts the sliding pulley to the outside, achieving relative or fully straighten of the piston according to the changing position of the intake bracket up or down from the center of the Engine core.

[0043] The design of this variable position helps to control the compression ratio of the piston by controlling In the intake stroke, and thus controlling the liter capacity, and consequently controlling the output power and torque of the engine

[0044] Also, in it, the piston sliding roller No. 4 moves from point H to point A, achieving a new compression stroke, which is the end of step No. 3

[0045] Step No. 4 is produced by giving a spark of combustion at point A to piston No 4. The power stroke occurs and step No. 4 is generated. In this step, the sliding roller No. 4 moves due to the power stroke from point A to point B (piston No. 4 power stroke) giving a rotation to turn the engine by 45 degrees, so roller No. 5 replaces roller No. 4 coming from point H to point A in preparation for the new power stroke, while the piston sliding roller No. 3 moves from point B to point C to achieve exhaust stroke. The piston sliding roller No. 2 moves from point C to point D to achieve intake stroke

[0046] The sliding roller of piston No. 1 moves from point D to point E (piston No. 1 compression stroke) A new compression stroke is achieved in a new half-cycle, by giving the combustion spark, a power stroke is produced at point E, and as a result of the power stroke, pulley No. 1 slides from point E to F, and so on until piston No. 1 reaches point A again to resume the cycle again, accompanied by all the pistons installed with it. At engine coreHere, the second power stroke occurs in the same cycle, so that we get a change of 45 degrees in one step resulting from two power strokes.Fig.3

[0048] Description of Embodiments

[0049] Wheel Internal combustion engine

[0050] This wheel engine consists of 5 main parts, which are as follows

[0051] 1 - Two external engine covers (both sides of the engine

[0052] 2- circular wave frame (Zigzag circular frame)

[0053] 3- Pistons

[0054] 4The rotating block carrying the cylinders and pistons (the engine core)

[0055] 5- The main axis that holds the turntable

[0056] 6-two intake brackets

[0057] Explaining of the engine parts and the function of each part and the operation method as below

[0058] the two engine covers as shown in pic no 4

[0059]

[0060] The front and rear covers of the engine are two large circular discs that Represent the outer borders of the engine. They represent the diameter of the engine, and 8 ventilation holes are Engraved inside them. In the case of natural cooling with air, air passes through them to cool the engine core, but in the case of forced cooling with Water, Water passes through them to cool the engine core. Also engraved in these covers Two opposing circular central holes through which the main shaft carrying the rotor engine core

[0061] They have holes through which connecting bolts pass between the two outer covers and the circular wave frame between them as shown below

[0062] circular wave frame.(zigzag)

[0063] It is a large hollow circle whose diameter is the diameter of the engine and the diameter of the two outer covers, and this circular wave frame is between the two engine covers, such as (sandwich stuffing), so that its thickness is the distance between the two engine covers

[0064] It represents the outer borders of the engine, a regular round from the outside and zigzag from the inside towards the center of the engine core and surrounds the engine core And the cylinders and pistons, which is responsible for the shape of the reciprocating movement of the Pistons resulting from the pistons slipping a rotational slip on this frame.

[0065] This zigzag wave frame is in the form of a sinusoidal wave consisting of 8 waves connected in series (4 waves at the top and 4 waves at the bottom) so that the difference between the top and bottom of this wave is the difference between the top dead center and the bottom dead centerlt's the piston's stroke

[0066] - pistons

[0067] It consists of a head with 3 rings connected to a non-jointed arm and a pulley Attached to the end of this arm called a sliding pulley. Or sliding rollers And these Sliding rollers allow the piston to slide on the circular wave frame. (zigzag) There are also guide rollers that control the reciprocating movement of the piston, which are 4 rollers installed vertically in the engine core at the top of the edge of each cylinder (2 right rollers and 2 left) in order for the piston arm to slide in its reciprocating movement and These pulleys are also used as a guide for the piston arm

[0068] The length of the piston arm is calculated as follows arm length = cylinder length - piston head length + two guide rollers diameters + slip roller radius (as shown in the diagram)

[0069] Turntable (engine core)

[0070] It is a uniformly rotating disk and this disc diameter equal to the same engine diameter minus the two tops of the circular wave frame and two sliding pulleys and two guiding pulleys

[0071] So, the diameter of the engine core = the diameter of the engine - two tops of the wave frame - two sliding pulleys - two steering pulleys(guiding roller)

[0072] As for the thickness of the disc, it is the same as the thickness of the zigzag circular frame

[0073] The thickness of the engine core has 8 cylinders drilled inside, starting from the circumference of the circle and ending in the direction of the center of the circle so that the difference between the axis of each cylinder and the adjacent cylinder is 45 degrees It is of appropriate length so that the ends of the cylinders do not meet together at the center of the disc. The shape issimilar in this description to the triangles cheese box (the cheese box is divided into 8 equal triangles, so we will dig a small cylindrical tunnel with a pencil at the base of each triangle heading to the top of the triangle with a suitable length so that it does not touch the top of the triangle Or the sides of the triangle) This tunnel, which was drilled, represents the cylinders in which the pistons operate, and accordingly, the cylinders are engraved perpendicular to the center of the heart of the engine, which is installed on a rotating axis.

[0074] These cylinders rotate with the axis of the engine core in a circular motion carrying the pistons which slide inside them in a reciprocating motion up and Down

[0075] This movement is controlled by 4 rollers installed vertically in the engine core at the top edge of each cylinder, 2 rollers to the right and 2 to the left so that the piston arm slides on them in its reciprocating motion.

[0076] These pulleys also act as guides for the piston arm When the piston arm pulley meets the top of the wave, it gives complete piston compression, and when it meets the bottom of the wave, it gives Complete piston compression.

[0077] The main axis as shown in pic no 5

[0078] It is an axial axis extending between the two outer engine covers and Carrying the engine core, which moves its rotational movement on it

[0079] The main axial shaft has two exhaust holes in the exhaust stroke and two air intake holes in the intake stroke. So that all the cylinders rotate on these openings ports in their rotational movement to empty the exhaust and withdraw the mixture

[0080] In the case of a gasoline-fueled engine, spark plugs are installed on it, and 2 fuel injectors are installed on it. So that all cylinders rotate on these fuel injectors and spark plugs in their Rotational movement to feed them with fuel. And give the spark of ignition in precise synchronization timing

[0081] And the exhaust pipe is installed on this axial towards the rear cover of the engine, and the intake pipe is installed on this axial towards the front cover for the engine

[0082] 6- intake bracket as shoe in pic no 6

[0084] The intake stroke takes place by means of the pulling intake bracket installed on the zigzag circular frame, which in turn attracts the sliding pulley to the outside, achieving relative or fully straighten of the piston according to the changing position of the intake bracket up or down from the center of the Engine core. The design of this variable position helps to control the compression ratio of the piston by controlling In the intake stroke, and thus controlling the liter capacity, and consequently controlling the output power and torque of the engine.Operation method

[0085] Achieving 16 strokes for 8 pistons in the full cycle of the engine, so we get 2 power strokes for each piston in one revolution and It is possible to obtain one power stroke for each piston with 8 power strokes per Revolution, and we obtain them through

[0086] An innovative mechanism to (intake bracket) disable 8 strokes and obtain strokes, By making it not pull the piston down as it does its normal action on the intake stroke to disable 8 strokes and get 8 Strokes and this helps to control the power generated by the engine

[0087] It is possible to design this engine to include 2 engine cores on the same circular wave frame, and each core carries inside it 8 cylinders,

[0088] i.e. 8 cylinders * 2 engine cores = 16 cylinders, from which we get the full power of the engine

[0089] One of the important features of this engine is the possibility of adding an unlimited number of 3, 4, 5 or so on. An unlimited number of engine cores on the same circular wave frame to double the output power according to the number of engine core as we wish.

[0090] The oil lubrication circuit is as shown in Figure No7

[0092] oil lubrication circuit It consists of 8 oil channels or 8 oil ducts engraved in the engine core through which the oil passes from the engine cavity to the main axis for lubricating the main axis and the rest of the engine parts such as (sliding rollers, guide rollers and pistons are lubricated and cooled by immersion in oil through the oil in the engine cavity As the engine core is like rotary wheel, and the rollers slide on it from the bottom to immerse in the oil, then ascend to the top to distribute the oil to the rest of the parts, andwith the speed of rotation of the engine core, we Ensure a good distribution of oil throughout the engine.

[0093] Firstly, the natural cooling

[0094] Firstly, the natural cooling, which depends on the design of the shape of the two engine covers with the cooling holes in the in the form of a jet fan

[0095] This cooling depends mainly on the friction between the outer body of the combustion cylinders, which are engraved in the engine core, which rotates at a high speed, and the atmospheric air current that passes through the engine cover openings in the direction of these cylinders to cool them, also passing through the openings between these cylinders to complete cooling from all directions

[0096] Second, forced air cooling

[0097] The possibility of adding a cooling fan in the front cover to push larger amounts of air to increase the efficiency of air passage between the cylinders

[0098] Third, the possibility of not cooling with air

[0099] and using forced cooling with water In this case, all the openings of the two external engine covers are closed, and since the engine core that rotates inside the two fixed engine covers is isolated with oil seals from both sides, so that no oil passes in the area between the engine core and the two covers, then we can cool this area with water, which is cooling the engine core with its cylinders, so that the water enters cold By pushing through a water pump from the front cover and exiting from the rear cover hot to the heat exchanger, thus completing the cooling circuit

[0100] The stage of this engine development

[0101] It is possible to make the rotating engine core carry 12 cylinders that operate on 3 air feeding ports, 3 exhaust exit ports, 3 spark ignition 3 fuel injectors, 3 intake bracket , and the zigzag circular frame carries 12 waves, which leads to a significant increase in the output torque, which is about 33%. and this also lead to smoothness In engine performance and ensuringthat the energy flow resulting from the power stroke is not interrupted due to the increasing in number of cylindersIndustrial Applicability

Claims

AMENDED CLAIMS received by the International Bureau on 09 February 2025 (09.02.2025)

1. The first protection claim, which is the protection of a four- stroke internal combustion engine that has cylinders and pistons converting rotational motion into linear motion and vice versa, without a crankshaft, camshaft, or traditional valves. This engine is shaped like a circular disc consisting of 8 cylinders, with a horizontally drilled cylindrical ring (central ring) at the center of the disc. The disc's thickness has 8 vertically drilled cylinders, each extending longitudinally and perpendicular to the disc's center, with the start of the cylinder facing the disc's perimeter and the cylinder head towards the central ring. Each pair of cylinders extends along an axis, meaning there are 4 axes for the eight cylinders, each cylinder featuring an open port at its head towards the central ring, creating eight open ports spaced equally around the center of the disc.An additional cylinder passes through the center of the disc, having open ports matching those of the central ring and extending longer on both sides, supported at its outer ends by two ball bearings. This is referred to as the inner ring of the engine's core and is fixed as a single unit with the disc, supporting the disc during its rotation when the engine is running. We call the disc the (engine core) and the cylinder it rests on the inner ring. Inside this inner ring, there is another stationary cylinder divided internally into open- ended longitudinal channels, referred to as the axial shaft or feed axis. Its outer wall has open ports connected to these channels, aligned with the open ports of the cylinders. The cylinder open ports are naturally closed by the wall of the feed shaft and only open into the channels when aligned with the feed shaft open ports at various rotational angles of the engine's core, allowing them to open and close naturally based on their position around the engine's center, eliminating the need for traditional valves and their associated moving mechanical parts.Additionally, at the same level on the wall of the feed shaft, there are 2 fuel injectors spaced 180 degrees apart, as well asAMENDED SHEET (ARTICLE 19)2 spark plugs, all contributing to the operation of each cylinder, significantly reducing the number of injectors and spark plugs needed. We obtain the motion output through the inner ring, which extends its ends through a ball bearing outside the engine.Meanwhile, the pistons enter and exit from their starting point at the disc's perimeter (the engine core) with the help of a connecting rod, which is fixed vertically and has longitudinal grooves on its sides. The other end is attached to a motion roller called the sliding roller, and this rod is referred to as the non-jointed piston arm. The piston arm slides, carrying the piston head and the sliding roller through the two side grooves, where free-moving rollers facilitate its upward and downward movement. This roller call guide roller is mounted in pairs above each other with right and left supports beneath each cylinder on the outer diameter of the engine's core. Surrounding this entire structure is a wavy circular frame, which is a circular metallic frame surrounding the engine core with the same thickness as the disc (engine core), uniformly rounded on the outside but internally wavy with 8 connected sinusoidal waves, as shown in Figure 3 in the detailed description. As the engine's core rotates, the sliding roller glides along the wavy circular frame, causing the pistons to move in and out. and The vertical pressure of the pistons on the top wave of the frame allows it to slide down the wave by 45 degrees, generating a very high torque because the sliding roller, combined with the piston arm, and the radius of the engine core acts as a very high torque lever. Thus, the resulting torque is significant, and we can eliminate the complex crankshaft technology.Additionally, there is a movable part in the engine that allows us to reduce the displacement, referred to as the intake bracket for fuel efficiency.The goals of this design are:

1. To benefit from a larger displacement with less size and weight.

2. To achieve greater torque and higher speed.AMENDED SHEET (ARTICLE 19)3. To reduce the moving mechanical parts involved in the operation that consume part of the engine's output power due to friction and cause an increase in the engine's temperature.

4. To achieve natural cooling without an external cooling circuit.

5. To eliminate the need for additional attachments like intake and exhaust pipes around the engine, with a harmonious design resembling the final shape of a car wheel.

6. To allow for adjusting and changing the displacement during engine operation as needed for fuel efficiency and engine maintenance.

7. One of the design features is that all rotating parts operate on a ball bearing system rather than a bushing or sleeve system, which means they do not require a complex lubrication cycle with high pressures.The engine is suitable for cars and heavy machinery that require high torque, as well as for aircraft and machines needing a powerful, lightweight, and compact engine.

2. According to the first protection claim, protecting the engine coreAccording to the first protection element, we protect the engine core, which consists of eight cylinders, each pair on an axis, and this core rotates around its axis. Changing the rotation angles of the engine's core relative to the wavy circular frame and the fixed feed axis contributes to the operation itself and the arrangement of strokes, as well as the automatic opening and closing of the intake and exhaust ports, without the need for traditional valves.Since the motion output is obtained from the inner ring of the engine core, positioning the cylinders with their heads toward the center of the engine core circle and their ends toward the circumference of the engine core circle allows the cylinders themselves, along with the complementary piston arm and half of the sliding pulley down to the base of the wave of the wavy circular frame, to form a very long torque arm that significantly improves the engine's torque.Additionally, dividing the engine core into 8 cylinders, along with dividing the wavy circular frame into 8 waves consisting ofAMENDED SHEET (ARTICLE 19)4 peaks and 4 troughs, with a 45-degree difference between them, and their interaction to work on 8 strokes — where in each stroke two cylinders operate on the same axis during the power stroke — allows us to achieve one rotation of the engine's core through 16 power strokes. This results in a very high energy density and better power flow.

3. According to the first protection element, we protect the wavy circular frame, the outer diameter of this frame is a circle representing the external boundaries of the engine, i.e. , the engine wall. It is internally divided toward the engine core into 8 equal sinusoidal waves to convert reciprocating motion into rotational motion and rotational motion into reciprocating motion. This is achieved through sliding pulleys connected to the pistons via non-articulated arms (piston arms), which rise and fall on the peaks and troughs of the waves 8 times — four ascents and four descents for each pulley. This means that each piston rises 4 times and falls 4 times in one complete rotation of 360 degrees, achieving 4 complete strokes for each cylinder: intake, compression, power, and exhaust. Every half rotation of 180 degrees allows the design to yield 2 power strokes for each cylinder in one complete rotation, resulting in 2 power strokes multiplied by 8 cylinders. Thus, we achieve 16 power strokes for each rotation, meaning the engine operates at double the volumetrically capacity of the eight cylinders. This represents the maximum utilization of the engine's liter capacity. By using this design, we can double the liter capacity using the same size.

4. According to the first protection element, claim 4 is the integration of the previously deposited protection elements numbered 4, 10, 13, 14, 15, 16, and 17 into a new amended protection claim, which is claim number 4, to provide a more detailed explanation with the same originally deposited content.The new amended protection claim number 4 is as follows. According to the first protection element, we protect the design of the feed axis or the fixed axial shaft, which is a hollow cylinder divided internally into eight longitudinal tunnels, with a smooth outer wall. This design allows us to use only 2 fuelAMENDED SHEET (ARTICLE 19)injectors to feed eight cylinders, 2 spark plugs to operate eight cylinders, 2 intake open ports to feed eight cylinders, and 2 exhaust open ports to operate eight cylinders. All these open ports, injectors, and spark plugs are arranged circularly on the outer wall of the cylindrical feed axis, and they are all connected by longitudinal channels or tunnels extending through the shaft and leading to the ends. This replaces the need for 8 intake bracket s, 8 exhaust bracket s, 8 injectors, and 8 spark plugs for each cylinder in the traditional engines currently available. This design reduces the size and weight of the engine, lowers costs, and facilitates disassembly, installation, maintenance, and troubleshooting if necessary. Moreover, the design eliminates the need to run pipes around the engine for intake and exhaust, as air enters from the front end of this axial shaft, mixes with fuel inside the engine, ignites, and then the exhaust gases exit from the rear end of the feed axis. Additionally, the design allows us to remove and install the feed axis or the axial shaft independently without needing to disassemble any other part of the engine, while also increasing the efficiency of air intake and exhaust due to the straightness of the intake and exhaust tunnels or channels.

5. Protection claim number 5 is new.According to the first protection claim, we protect the design of the front and rear engine covers. We also protect the square ventilation openings in the covers opposite the cylinders and the triangular spaces between the cylinders in the engine core, which allow air to pass through. These spaces act as moving blades that increase the friction of the external walls of the cylinders with the air and enhance the surface area of the cylinder for effective heat dissipation, thereby increasing cooling efficiency.The gaps between the cooling openings are strong and thick, allowing for the proper pressure of incoming air on the cylinders to improve cooling efficiency.We also protect the rounded outer area of the covers, which, together with the wavy circular frame between them, forms a round open box only on the side of the engine core, similar to a car wheel. The thickness of the outer circumference of theAMENDED SHEET (ARTICLE 19)engine core moves on the two ends of this internal box. There are two oil seals on each side of the outer circumference of the covers near the engine core, which create a seal between the rotating engine core and the stationary covers. The engine core rotates with these two oil seals and rubs against the covers to ensure a tight closure on the cylinders, sliding pulleys, guiding pulleys, piston head, and piston arm. A small amount of oil is placed in the engine box so that each sliding pulley dips into the oil when it moves down and rises to distribute it to the other parts. Additionally, there are small channels in the engine core parallel to the cylinders that extend to the feed axial shaft for lubricating the feed shaft. This design of the covers allows for natural cooling and lubrication of the engine without additional accessories.

6. According to the first protection claim, claim 6 is the integration of the previously deposited protection elements numbered 6, 7, and 12 into a new amended protection claim, which is claim number 6 to provide a more detailed explanation with the same originally deposited content.The new amended protection claim number 6 is as follows for the first protection element, we are protecting the floating motion technique or the sliding assembly. This consists of:

1. A non-jointed piston arm, which has longitudinal grooves carved on its sides and is vertically fixed at one end to 2. The piston head. It is secured at its other end with 3. A sliding pulley. These three parts are interconnected as one unit and move together, as illustrated in figure 2 in detailed description. They are not fixed to any other part of the system. However, this assembly interacts with the guide pulleys, the circular frame, and the cylinders to convert reciprocating motion into rotary motion and rotary motion back into reciprocating motion

7. According to the first protection element, claim 7 is Rephrasing and explaining the previously deposited protection Claim No.11 numbered into a new claim no 7 and According to the first protection element, we protect the system for automatically opening and closing the cylinder ports without the need for traditional valves, based on the angle of rotation of the engine core relative to the feed axis, with a single port for eachAMENDED SHEET (ARTICLE 19)cylinder. This port allows for 8 strokes every 360 degrees, with two power strokes for each cylinder in each complete rotation of 360 degrees. This is achieved by gathering the eight cylinder open ports to face the inner cylindrical ring carrying the engine core and utilizing the rotation of the inner ring around the feed axis or the axial shaft. The interaction of the inner ring open ports with the outer cylindrical wall and the open ports of the feed axis leads to:Simplifying the system and facilitating the easy and quick entry of air and exit of exhaust. Reducing the need for many open ports or valves. Decreasing the moving mechanical parts, such as camshafts, which consume a significant portion of the engine's power output and generate heat.Eliminating the need for additional external attachments like intake and exhaust pipes. Better utilization of space.

8. According to the first protection element, claim 8 is the integration of the previously deposited protection elements numbered 8,9. Merging protection claims 8 and 9 under the name Protection Claim No. 8.Protection claim No. 8 According to the first protection claim, we protect the system for controlling and adjusting the engine's liter capacity and the number of power strokes during engine operation. This function is performed by two main components in the engine:

1. The intake bracket and 2. The fuel injector. These can be adjusted while the engine is running, allowing us to control the injection timing through the intermittent electrical signal to the injector, as well as controlling the distance of the intake bracket from the center of the engine core by pulling or pushing the thick metallic rectangular plate on which the intake bracket is mounted inwards or outwards by rotating the screw pulley fixed to it from outside the engine in a clockwise or counterclockwise direction. This process can be done manually or by using an actuator attached to the screw pulley, which applies to two intake brackets in the engine. The intake bracket controls 70% to 100% of the piston stroke during the intake stroke, allowing us to reduce the full use of the cylinder capacity while minimizing the injector opening time and saving fuel in case of reduced load. Additionally, we can push one ofAMENDED SHEET (ARTICLE 19)the intake brackets inward to its maximum extent to completely prevent its intake stroke and disable the subsequent injector to save fuel while keeping the engine running through the other intake bracket and the other injector, albeit at a lower capacity. This control helps in conserving energy and fuel when not needed.

9. Modification of The previously deposited protection claim number 18 and renaming it as claim number 9.According to the first protection element, we ensure the ease of engine maintenance through:

1. The ability to remove and install the axial shaft or feed shaft independently without the need to disassemble any other part of the engine. By loosening the four nuts that connect the front cover of the engine to the wavy circular frame and removing the cover, we can see all the components inside the engine and work on them, such as the intake bracket and guiding pulleys. By removing the guiding pulleys that control the floating motion assembly and extracting the piston head along with its arms and sliding pulley, we can easily access all components. This is because the design of the engine keeps all components at the same level: the engine core, the wavy circular frame, the cylinders, guiding pulleys, sliding pulleys, arms, and pistons are all aligned. Thus, once the front cover is lifted, all engine components are visible, allowing us to test and repair any part we desire without needing to remove a specific component to access another. This makes it possible for anyone with basic experience to disassemble and reassemble the engine, saving time, effort, and money for the userAMENDED SHEET (ARTICLE 19)
