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.

Summary 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 to obtain 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 cycle

Technical 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 large

Solution 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 circuits

Advantageous 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 block

Brief 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 it

Fig.1

Brief 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 rod

Fig.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 (piston No. 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 is similar 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, and with 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 ensuring that the energy flow resulting from the power stroke is not interrupted due to the increasing in number of cylinders

Claims Inventor: Hany William Hefzallah Attia

[Claim 1] The first protection element, which is the protection of

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 four-stroke engine operates without crankshafts or camshafts. The cylinders are not fixed, but move in a rotational motion, and the pistons slide in a floating motion.

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.

Each of the two cylinders is extended on one axis, and the cylinder heads end with round port that are feed and exhaust ports, all of which overlook a hollow inner ring in the center of the engine core.

[Claim 3] According to the first protection element, we protect the corrugated circular frame consisting of 8 complete sine waves from the inside towards the engine core. The outer diameter of this frame is a circle representing the outer limits of the engine, i.e. the engine wall, which is responsible for converting the reciprocating piston movement to rotational and vice versa.

[Claim 4] According to the first protection element, we protect the main fixed axle, which is called the feeding axis, and from it the cylinders are fed with air and fuel because it is empty and has channels for intake, exhaust, fuel, and spark.

[Claim 6] According to the first protection element we can protect, the Non-articulated piston rod.

[Claim 7] According to the first protection element we can protect, The floating motion of the piston by means of the guide rollers.

[Claim 8] According to the first protection element we can protect, Controlling the engine's liter capacity by repeating the power the stroke of one piston in the same cycle twice And this lead us to control the speed and the output power of the engine.

[Claim 9] According to the first protection element we can protect controlling the piston travel during the intake stroke by means of a mechanical meniscus connected to a mechanical arm and this leads to control the compression stroke

[Claim 10] According to the first protection element we can protect the rotation of all cylinders in their rotational motion on the number of 2 spark plugs to obtain the ignition spark

[Claim 11 ] According to the first protection element, we protect only one hole for each cylinder that serves as an intake and exhaust hole.

[Claim 12] According to the first protection element, we protect the mechanism for transmitting the reciprocating movement from the piston to the controlled arm with the guide rollers installed around the circumference of the engine core circuit. There are 2 guide rollers above each cylinder, right and left, to the sliding rollers that slide on the corrugated circular frame, so the angle of movement of the sliding roller changes from Vertical to circular at a rate of 45 degrees, and this angular movement is transmitted through the piston arm in the opposite direction, back to the guide rollers, which transmit the movement to the circumference of the engine core circle, causing the engine core to rotate at an angle of 45. This mechanism represents a lever of the second type. Where the sliding pulley represents (force), the guide pulley represents (resistance), and the inner ring of the engine core represents (the fulcrum axis), from which we obtain the result of the movement. The greater the distance between the fulcrum axis and the bottom of the wave, the greater the length of the torque.
