Description

  The present invention relates to a circulating carbon dioxide engine system using a satellite-type induction drive wheel using magnetic force.

  An engine system that recovers and reuses discharged carbon dioxide gas has been invented in an engine that drives an actuator by a force due to volume expansion when high-pressure carbon dioxide gas reaches normal pressure. In such an engine system, if the transmission loss when transmitting the driving force of the engine to the compressor is large, energy is wasted and efficient circulation cannot be realized.

  The use of magnetic force can be considered as a solution for such transmission loss. For example, by providing a magnet on the bottom of the wheel and fixing the magnet so as to face the magnet, the wheel is lifted using the repulsive force between the magnets, and this repulsive force is also used for rotation It is based on.

However, in the method of simply providing a magnet on the bottom surface of the wheel as described above and fixing the magnet so as to face the magnet, repulsion and attraction, which are the properties of the magnet, have not been fully utilized.

The purpose is to provide a gas engine system.

In order to achieve the above object, a circulation type carbon dioxide engine system according to the present invention comprises a circulation type carbon dioxide engine having a carbon dioxide engine powered by high-pressure carbon dioxide and a compressor for compressing carbon dioxide exhausted from the carbon dioxide engine. In the gas engine system, the carbon dioxide gas engine sucks high-pressure carbon dioxide gas into a sealed inner chamber, operates an operating element by expansion force when the high-pressure carbon dioxide gas is exhausted, and the compressor The carbon dioxide engine is driven by the driving force transmitted by the induction drive wheel, and the carbon dioxide gas having a high pressure by the compressor is sucked into the carbon dioxide engine, and the induction drive wheel has a large diameter. It consists of a single drive wheel and a plurality of satellite wheels with small diameters, and the drive wheel and the satellite wheel are in the opposite direction. Magnets are attached to a plurality of sections provided on the circumferential surfaces of the drive wheel and the satellite wheel, and all the base magnets attached to the drive wheel have the same polarity and are attached to the satellite wheel. The polarity of the satellite magnet is changed alternately, and a slight gap is provided between the base magnet and the satellite magnet. The satellite magnet has a different polarity than the magnet of the same polarity. Is large.
Further, in the circulating carbon dioxide engine system according to claim 1, when the satellite magnet has the same polarity as the base magnet, the positions of the rear end corners of the base magnet and the satellite magnet approaching the base magnet coincide with each other. When the front end corner is inclined at a predetermined angle with respect to the tangent to the rotation trajectory of the satellite wheel, the base magnet and the position of each front end corner of the satellite magnet approaching the base magnet when the base magnet is different in polarity The rear corners are inclined at a predetermined angle with respect to the tangent to the rotation trajectory of the satellite wheel, and the mounting angle of the heteropolar base magnet is larger than the mounting angle of the homopolar base magnet It is characterized by.

A large number of alternating satellite magnets are mounted, and the satellite magnet has a difference so that the mounting angle of the magnet with a different polarity is larger than the mounting angle of the magnet with the same polarity with respect to the base magnet. Since the N pole and the S pole of the satellite wheel are mechanically interchanged in a state where it is always larger, it is possible to assist the rotation of the drive wheel and minimize the transmission loss of the wheel. Thereby, carbon dioxide gas can be circulated efficiently.

  Next, the circulating carbon dioxide engine system according to the present invention will be described in more detail with reference to the drawings showing embodiments. For convenience, portions having the same function are denoted by the same reference numerals and description thereof is omitted.

  FIG. 1A shows a circulating carbon dioxide engine system 100 according to the present invention. In FIG. 1A, the drive device includes a drive source unit 20, a transmission unit 40, and a piston unit 50, and the transmission unit 40 is mainly configured by the induction drive wheel 1. More specifically, the drive source unit 20 includes an engine or a motor that is a drive source. In the case of the illustrated example, the engine includes a carbon dioxide engine 21 that drives the rotor by a force due to volume expansion when carbon dioxide supplied in a high pressure state becomes atmospheric pressure. The carbon dioxide engine 21 has two inner chambers 23 having a circular cross section formed in a housing 22 formed by horizontally placing a cylinder made of metal, for example, an aluminum alloy, and a rotor 24 is provided in each of the two inner chambers 23. The carbon dioxide gas supply port 25 and the discharge port 26 are provided at required positions. The carbon dioxide gas engine 21 shown in the figure is a dual-type carbon dioxide gas engine having two five-surface rotors, and each rotor 24 is provided with two carbon dioxide supply ports 25 and two discharge ports 26.

  The cross section of the rotor 24 has a shape in which each side of the regular pentagon is concaved in a 1/5 arc shape toward the inside, and each vertex is bent. The top portion is provided with a pressure seal, and the pressure in the five working chambers formed by the inner peripheral surface of the housing and the outer peripheral surface of the rotor is held. This pressure seal also serves as an oil seal. Reference numeral 27 denotes a rotor shaft. The two rotors 24 are axially attached, and one end is fixed to the drive pulley 28 and the other end is fixed to a flywheel (not shown). At this time, the rotors 24 are provided so that the phases of the operation surfaces do not overlap to ensure smooth output. Reference numeral 29 denotes a flywheel housing incorporating the flywheel (not shown). Reference numeral 30 denotes a starter.

  In the housing 22, two supply ports 25, 25 and two discharge ports 26, 26 are provided on the peripheral wall of each inner chamber 23. The supply port 25, the discharge port 26, the other supply port 25, and the other discharge port 26. Are provided at equal intervals every 90 °. The discharge ports 26 and 26 are formed larger than the supply ports 25 and 25.

  Each inner chamber 23 of each housing 22 is supplied with high-pressure carbon dioxide gas 35a (shown in FIG. 1B), and each rotor 24 is connected to the rotor shaft by a force due to volume expansion when the carbon dioxide gas 35a reaches atmospheric pressure. Rotate around 27.

  The transmission unit 40 includes a plurality of (three in the illustrated example) induction driving wheels 1 connected in series, and transmits the driving force of the driving source unit 20 to the piston unit 50. More specifically, 41 is a passive pulley, and a drive belt 42 is rotatably spanned between the drive pulley 28 and the driving force of the carbon dioxide engine 21 is transmitted. The passive pulley 41 has a gear (not shown). The gear meshes with the primary drive gear 43, and the primary drive gear 43 meshes with the secondary drive gear 44. A wheel shaft 45 is attached to the drive wheel 3 and the drive gear 4 to transmit the driving force of the carbon dioxide engine 21 transmitted to the secondary drive gear 44 to the drive wheels 3 and the drive gear 4. A crank 46 is rotatably provided on the wheel shaft 45, and a crank arm 47 is reciprocally connected to the crank 46. A lever rod 51 constituting the piston portion 50 is rotatable on the crank arm 47. Connected.

  The piston portion 50 includes the lever rod 51, a connecting rod 52 that is rotatably connected to the lever rod 51, and pistons 53, 54, and 55 that are connected to the connecting rod 52 so as to reciprocate. 53 is a primary compression piston, 54 is a secondary compression piston, 55 is a tertiary compression piston, and 56 is a cylinder block. The lever rod 51 is formed such that the fulcrum 51a is eccentric to the action point 51b side. For example, when the length between the fulcrum 51a and the action point 51b is m and the length between the fulcrum 51a and the force point 51c is n as in the illustrated embodiment, when m: n = 1: 3, The load applied to the pistons 53, 54, 55 during compression is reduced to 1/3 for the lever rod 51.

  Each piston 53, 54, 55 is provided with an inlet 53a (shown in FIG. 1C), 54a, 55a (shown in FIG. 1B) and outlets 53b, 54b, 55b (shown in FIG. 1B). The inlet 53a of the piston 53 is connected to the discharge port 26 of the carbon dioxide engine 21 via the exhaust recovery tank 80 (shown in FIGS. 1C and 2), the inlet 54a of the piston 54 is connected to the outlet 53b of the piston 53, and the piston 55. Since the inflow port 55a is connected to the outflow port 54b of the piston 54, the carbon dioxide gas 35b (shown in FIG. 1C) discharged from the carbon dioxide engine 21 is supplied from the inflow ports 53a, 54a, 55a to the pistons. 53, 54, and 55, compressed in stages by the pistons 53, 54, and 55 to a predetermined high pressure state, and then flowed out of the outlets 53b, 54b, and 55b, and the high-pressure carbon dioxide gas 35a (see FIG. 1B) and supplied to the carbon dioxide engine 21. Reference numeral 60 shown in FIG. 1B denotes an initial tank composed of a pressure vessel for storing the virgin carbon dioxide gas 35a, and is connected to a pipe for supplying the carbon dioxide gas 35a via a switching valve 61 and a three-way switching valve 63. 65 is a sensor for detecting the concentration (liquefaction purity) of the carbon dioxide gas 35a in the pipe, 67 is a valve control device for controlling the switching valve 61 and the three-way switching valve 63, and the concentration of the carbon dioxide gas 35a in the pipe is When lowered, the switching valve 61 and the three-way switching valve 63 are operated to supply virgin carbon dioxide gas 35a from the initial tank 60 into the pipe.

  Next, each enthalpy zone will be described based on FIG. 2 and FIGS. 3A and 3B. The drive source unit 20 constitutes a primary enthalpy zone. The mechanism of the drive source unit 20 will be described with reference to FIG. First, the flywheel is rotated by the starter 30 (steps S1 and S2). Then, the rotor shaft 27 and the rotor 24 that are linked to this rotate (steps S3 and S4). When attention is paid to one working chamber among the five working chambers formed by the housing inner peripheral surface and the rotor outer peripheral surface, when the supply port 25 is “open” with respect to the working chamber due to the rotation of the rotor 24, the high pressure state is reached. Carbon dioxide gas 35a flows into the working chamber (step S5). The carbon dioxide gas 35a starts to expand as soon as it flows into the working chamber. This expansion once ends when the rotor 24 further rotates and the supply port 25 is closed with respect to the working chamber (step S6). This is because the expansion of the carbon dioxide gas 35a is performed within the limit of the volume of the working chamber. This is temporarily called “sub-expansion”. The pressure energy received by the rotor 24 during the sub-expansion receives the pressure on the entire rotor surface, as in the gasoline engine. That is, in the suction expansion stroke, the carbon dioxide gas 35a moves to the next expansion / discharge stroke in a state where the stress of the subexpansion energy is accumulated and held.

  In the expansion / discharge stroke, the carbon dioxide gas 35a becomes an atmospheric pressure and expands explosively at the moment when the discharge port 26 is "open" by the rotation of the rotor 24, that is, when the discharge port 26 is in a pinhole state (step S7). . A force is applied to rotate the rotor 24 by the action of the exhaust gas accompanied by the explosive expansion. The working chamber from which the carbon dioxide gas has been exhausted maintains the atmospheric pressure until the supply port 25 comes to the “open” position again (step S8). The rotational force of the rotor 24 is transmitted to the rotor shaft 27 and the drive pulley 28 (steps S9 and S10), a part of which is used for driving an automobile, for example, and the rest is the transmission unit 40 and the piston unit. 50 is used to circulate carbon dioxide gas.

  As shown in FIGS. 3A and 3B, in the first enthalpy zone 20, the energy of the carbon dioxide gas 35a supplied to the carbon dioxide engine 21 is mechanically changed through a suction expansion stroke, an expansion discharge stroke, and an atmospheric pressure maintaining stroke. It is a process until it is converted to output. The carbon dioxide engine used in the first enthalpy zone is preferably a perfect circle rotation engine, and more preferably a type that performs expansion a plurality of times during one rotation. When these conditions are satisfied, the energy conversion efficiency is high, and it is expected that a part of the energy when the compressed carbon dioxide gas expands is converted into a mechanical output.

  The transmission unit 40 constitutes a second enthalpy zone. The mechanism of the transmission part 40 is demonstrated based on FIG. The driving force generated by the first enthalpy zone is transmitted to the passive pulley 41 via the driving belt 42 (steps S11 and S12). Then, the secondary drive gear 44 rotates through the primary drive gear 43 for rotation ratio conversion (steps S13 and S14), and the wheel shaft 45 rotates by the rotation of the secondary drive gear 44 (step S15). ). Since the rotation of the wheel shaft 45 is transmitted to each drive wheel 3 and the drive gear 4, the drive wheel 3 and the drive gear 4 rotate (step S16). Then, the idle gear 6 that meshes with the drive gear rotates, and the satellite wheel 5 rotates in synchronism with this (step S17). When the drive wheel and the satellite wheel start rotating in this way, the south pole and the north pole of the satellite magnet 9 provided on the satellite wheel 5 act alternately on the north pole base magnet 7 provided on the drive wheel. Therefore, the suction action and the repulsion action are repeated (steps S18 to S25). The rotation of the drive wheel 3 is assisted by the interaction between the base magnet 7 and the satellite magnet 9, and the load on the wheel shaft 45 interlocking with the drive wheel is reduced as much as possible (step S26).

  The rotation of the wheel shaft 45 is transmitted to the crank 46 (step S27), whereby the crank arm 47 reciprocates (step S28), and the reciprocating movement causes the force point 51c of the lever rod 51 to move up and down. The connecting rod 52 provided at the action point 51b as a fulcrum moves up and down (steps S29 and S30). Then, the following piston portion 50 is operated by the vertical movement of the connecting rod 52.

  As shown in FIGS. 3A and 3B, the second enthalpy zone generates magnetic energy from the rotational output converted by the drive unit 20 by the magnetic interaction between the drive wheel 3 and the satellite wheel 5, thereby compressing the compressor ( The stroke is until the necessary power is induced in the piston portion 50). The induction drive wheel used in the second enthalpy zone is most preferably four sets.

  The piston part 50 constitutes a tertiary enthalpy zone. The mechanism of the piston part 50 is demonstrated based on FIG. In the piston portion 50, the pistons 53, 54, and 55 move up and down in conjunction with the connecting rod 52, and the carbon dioxide gas 35b is compressed stepwise. First, the carbon dioxide gas 35 b fed from the exhaust port 26 via the exhaust recovery tank 80 flows into the cylinder through the inlet 53 a as the primary compression piston 53 rises, and is compressed by the lowering of the primary compression piston 53. While flowing, it flows out from the outlet 53b as primary compressed carbon dioxide gas. Next, the primary compressed carbon dioxide gas flows into the cylinder from the inlet 54a as the secondary compression piston 54 rises, and is further compressed by the lowering of the secondary compression piston 54 while being discharged as the secondary compressed carbon dioxide gas outlet 54b. Spill from. The secondary compressed carbon dioxide gas flows into the cylinder from the inlet 55a as the tertiary compression piston 55 rises, and flows out from the outlet 55b while being further compressed by the lowering of the tertiary compression piston 55 (steps S31 to S31). S33). Thus, since the carbon dioxide gas 35b is compressed three times, the compression is performed smoothly. The carbon dioxide gas thus compressed is supplied to the carbon dioxide engine 21 as carbon dioxide gas 35a having a predetermined pressure (step S34).

  The exhaust gas collection tank 80 collects the carbon dioxide gas 35b cooled by the heat of vaporization exhausted from the exhaust port 26 of the carbon dioxide gas engine 21, and the carbon dioxide gas 35b collected here causes the pistons 53, 54, and 55 to be recovered. In order to cool, it passes the circumference | surroundings of each piston 53,54,55, and flows in into the piston 53 (step S35). Further, the compression heat generated when each piston descends is used to keep the carbon dioxide engine 21 at an appropriate temperature (step S36).

  As shown in FIG. 3A and FIG. 3B, the third enthalpy zone is a stroke until the carbon dioxide gas is sucked when the pistons 53, 54, 55 are raised, and the sucked carbon dioxide gas is compressed when the pistons 53 are lowered. In the third enthalpy zone, carbon dioxide gas is compressed by using gravitational energy due to the mass of the piston when the piston descends in order to reduce the load of compression resistance. In the compression stroke at the time of lowering, it is preferable that the mass of the piston is as large as possible in order to obtain more gravitational energy.

  The pressure adjustment tank 70 is provided to maintain the pressure of the exhaust recovery tank 80 at about atmospheric pressure. The carbon dioxide gas 35b discharged from the carbon dioxide engine 21 is sent to the pistons 53, 54 and 55 through the exhaust recovery tank 80 and subjected to compression processing. The exhaust recovery tank 80 and the pistons are compressed. Since it is difficult to match the processing amount with 53, 54, and 55, the processing amount of each of the pistons 53, 54, and 55 is often set larger than the processing amount of the exhaust recovery tank 80. In such a case, if the pressure in the exhaust recovery tank 80 decreases, the performance of the entire system including the pistons 53, 54, and 55 deteriorates. Therefore, the pressure adjustment tank 70 is provided to provide the pressure in the exhaust recovery tank 80. Is maintained. The exhaust recovery tank 80 is provided with a pressure adjustment valve 70 a on the exhaust port 26 side of the carbon dioxide engine 21, and on the other hand with a pressure adjustment valve 70 b on the air supply port 25 side of the carbon dioxide engine 21. Each pressure regulating valve 70a, 70b may be, for example, an electromagnetic valve that opens and closes a valve via a control system (not shown), or a check valve that mechanically opens and closes the valve. . For example, in the former case, when the exhaust recovery tank 80 is excessively depressurized, an ON signal is output from the control system to the pressure regulating valve 70a that has been "closed", and a needle valve (not shown) of the pressure regulating valve 70a is turned on. Since it is in the “open state”, carbon dioxide gas flows into the exhaust recovery tank 80 from the pressure adjustment tank 70, and the pressure in the exhaust recovery tank 80 is restored to about atmospheric pressure. Then, an off signal is output to the pressure adjustment valve 70a, and the needle valve returns to the “closed state”. In this way, the pressure in the exhaust recovery tank 80 is adjusted to about atmospheric pressure by the pressure regulating tank 70 having the pressure regulating valves 70 a and 70 b, and the volume expansion of the carbon dioxide gas 35 a supplied to the carbon dioxide engine 21. Is made efficient.

  FIG. 4 shows the configuration of the induction drive wheel 1 in detail. The induction drive wheel 1 includes a single drive wheel 3 having a large diameter and a plurality of satellite wheels 5 having a small diameter. The drive wheel 3 is rotated clockwise by a driving force from a drive source unit 20 described later, and the satellite wheel 5 can rotate counterclockwise. The drive wheel 3 is made of an appropriate metal material formed in a short cylindrical shape, and the base magnet 7 is attached to a number of sections provided on the circumferential surface. The satellite wheel 5 is made of a suitable metal material, is formed in a short cylindrical shape having a height corresponding to the height of the drive wheel 3, and the satellite magnets 9 are provided in the plurality of sections provided on the circumferential surface. 7 is attached with a small gap g. The base magnet 7 has the same polarity on the outer peripheral surface side of the magnet (N pole in the illustrated example). On the other hand, the satellite magnet 9 is formed by alternately changing the polarity on the outer peripheral surface side of the magnet from N pole to S pole. The satellite magnet 9 is different from the base magnet 7 in the mounting angle of the same polarity magnet and the different polarity magnet, and the mounting angle M of the different polarity (S pole in the illustrated example) satellite magnet 9 is the same polarity (see FIG. In the example shown, it is larger than the mounting angle L of the satellite magnet 9 of N pole). The drive wheel 3 and the satellite wheel 5 having the magnets 7 and 9 arranged in this way rotate in synchronization with the drive gear 4 and the idle gear 6, respectively. A plurality of satellite wheels 5 (four in the illustrated example) are provided on the peripheral surface of the drive wheel 3. In the illustrated example, the rotational speed of the satellite wheel 5 is set to be double that of the drive wheel 3.

The mounting angles M and L of the satellite magnet 9 will be described in detail with reference to FIG. The distance r from the center O of rotation of the satellite wheel 5 to the front end corner 9a of the satellite magnet 901 having a different polarity (S pole in the illustrated example) and the rear end angle of the satellite magnet 902 having the same polarity (N pole in the illustrated example) The distance r to the portion 9b is equal to the radius r of the circumferential orbit of the satellite wheel, and the distance r ₁ from the rotation center point O of the satellite wheel 5 to the front end corner portion 9a of the satellite magnet 902 of the same polarity is the radius The distance r ₂ to the rear end corner 9b of the satellite magnet 901 having a different polarity and shorter than r is further shorter than this. Therefore, the base magnet 7 fixed to the drive wheel 3 and the satellite magnet 9 having a different polarity are aligned with the front end corner 7a of the base magnet 7 and the position of the front end corner 9a of the satellite magnet 901 approaching the base magnet 7. At this time, the rear end corner 9b of the satellite magnet 901 is attached so as to be inclined at a predetermined angle M (30 ° in the illustrated example) with respect to the tangent line T of the rotation locus of the satellite wheel 5. On the other hand, the mounting angle of the satellite magnet 9 having the same polarity as that of the base magnet 7 (N pole in the illustrated example) is such that the rear end corner 7b of the base magnet 7 and the rear end corner 9b of the satellite magnet 902 approaching the base magnet 7. When the positions of the satellite magnets 902 coincide with each other, the front end corner portion 9a of the satellite magnet 902 is attached so as to be inclined at a predetermined angle L (15 ° in the illustrated example) with respect to the tangent line T of the rotation locus of the satellite wheel 5.

FIG. 6 shows the positional relationship between the base magnet 7 and the satellite magnet 9 as the drive wheel 3 and satellite wheel 5 rotate. When the satellite magnet 901 having a different polarity (S pole in the illustrated example) comes from the A position to the B position, that is, the position of the front end corner portion 7 a of the base magnet 7 and the front end corner portion 9 a of the satellite magnet 901 approaching the base magnet 7. , The rear end corner portion 9b of the satellite magnet 901 becomes a predetermined angle M (30 ° in the illustrated example) with respect to the tangent line T. At the position A, the angle M ₁ and the same L ₁ of the satellite magnet 912 having the same polarity (N pole in the illustrated example) with the same polarity (N pole in the illustrated example) with respect to the tangent line T are equal (in the illustrated example). In either case, 37.5 °). Next, when the satellite magnet 901 rotates and reaches the C position, the front end corner 9a of the next satellite magnet 902 is located at the rear end corner 7b of the base magnet 701. At this time, the angle M ₂ of the satellite magnet 901 is smaller than the predetermined angle M (22.5 ° in the illustrated example). In the D position to the F position, the next satellite magnet 902 has an influence of the magnetic field on the base magnet 701. The angles M ₃ and M ₄ of the preceding satellite magnet 901 with respect to the tangent T gradually become smaller as the positions D and E are reached. At the E position, the angle M ₄ with respect to the tangent T and the tangent T of the subsequent satellite magnet 902 are increased. Is equal to the angle L ₁ (7.5 ° in the illustrated example). When the position of the rear end corner 7b of the base magnet 701 and the rear end corner 9b of the satellite magnet 902 approaching the base magnet 701 coincide with each other, the front end corner 9a of the satellite magnet 902 is in contact with the tangent line T. The angle is a predetermined angle L (15 ° in the illustrated example). Next, at the G position, the angle L ₂ of the satellite magnet 902 is larger than the predetermined angle L (22.5 ° in the illustrated example), and at the H position, the angle L ₃ is further larger than the predetermined angle L (illustrated example). Then 30 degrees). At this time, that is, at the G position, the next satellite magnet 903 (S pole) is approaching, and at the H position, the angle M ₀ of the next satellite magnet 903 (S pole) is larger than a predetermined angle M ( (45 ° in the illustrated example).

FIG. 7 schematically shows the effective magnetic field and output distribution of the magnet at each position. In the lower graph of FIG. 7, the vertical axis represents the effective magnetic field area of the magnet and the distance between the front and rear end portions of the drive wheel 3 and the satellite wheel 5, and the horizontal axis represents the rotation direction of the wheel shaft 45. Reference numerals A to H indicate the positional relationship between the base magnet 7 and the satellite magnet 9 accompanying the rotation of the drive wheel 3 and the satellite wheel 5 in FIG. F ₁ is an attractive magnetic field in which an attractive force acts between the satellite wheel 5 of different polarity (S pole) and the drive wheel 3, and F ₂ is between the satellite wheel 5 of the same polarity (N pole) and the drive wheel 3. Shows the repulsive magnetic field where the repulsive force acts. For convenience, the drawings of the drive wheel 3 and the satellite wheel 5 in the above-described positional relationship are abbreviated.

  Next, the operating principle of the induction drive wheel 1 according to the present invention will be described with reference to FIGS.

  At the A position, a satellite magnet 901 having a different polarity with respect to the tangent line T is approaching the drive wheel 3 with the front end corner portion 9a facing down as if the airplane landed on the runway. At this time, as shown in the lower graph of FIG. 7, the suction force suddenly increases. Thereafter, the front end corner portion 9a of the satellite magnet 901 is rapidly separated from the drive wheel 3 as shown in the B position and the C position, so that the attraction force becomes maximum at the A position as shown in the lower graph of FIG. Immediately after the suction force decreases rapidly. As described above, the satellite magnet 901 having a different polarity makes a large angle toward the rear end corner portion 9b with respect to the tangent line T, and thus the front end corner portion 9a side approaches the drive wheel 3 in a linear state. However, since the magnetic field acts, the attractive force is mainly used to determine the rotation direction.

  From the C position to the D position, a satellite magnet 902 having the same polarity provided with a small angle with respect to the tangent line T approaches the drive wheel 3. At this time, since the satellite magnet 902 approaches the base magnet 701 substantially in parallel, the repulsive force increases as shown in the lower graph of FIG.

  Then, at the E position and the F position, the satellite magnet 902 that is substantially parallel to the tangent line T separates from the base magnet 701 with the front end corner portion 9a facing up as if the airplane took off from the runway. Therefore, the large repulsive force (shown in the lower graph of FIG. 7) assists the rotation of the drive wheel 3 at this time. As described above, since the satellite magnets having the same polarity are provided at a small angle toward the front end corner L with respect to the tangent line T, the satellite magnet 902 gradually approaches the drive wheel 3 in a planar state. A strong repulsive force acts for a longer time than a satellite magnet of the same polarity, and is used efficiently for rotation. Since the satellite magnet 902 expands in the rotation direction with respect to the base magnet 701, the repulsive force becomes a pushing force to the drive wheel 3 to assist the rotation.

  Thereafter, at the G position, as the satellite magnet 902 further moves away, the repulsive force becomes weaker as shown in the lower graph of FIG. As the satellite magnet 903 of the next different polarity approaches as it moves to the H position, the attractive force gradually increases.

Here, with reference to FIG. 8, let us look at changes in the magnetic fields of the satellite magnet 901 (S pole) and the base magnet 701 (N pole). FIG. 8A is a diagram schematically showing a change in the magnetic field when the approaching satellite magnet 9 has a different polarity (S pole) with respect to the base magnet 7. In this case, the attracting magnetic field F _{1 is formed} on the base magnet 7. Acts as an effective magnetic field, but the repulsive magnetic field F _{2 on} the back side of the magnet is an ineffective magnetic field. On the other hand, FIG. 8B schematically shows the change of the magnetic field in the case of the same polarity (N pole). In this case, the repulsive magnetic field F ₂ acts as an effective magnetic field, and the attractive magnetic field F ₁ becomes an ineffective magnetic field. Become. As described above, the magnetic field of the magnet is such that the effective magnetic field indicated by cross hatching intersects with any other ineffective magnetic field at any position from the A position to the H position. When this is arranged for each position, the attractive magnetic field F ₁ of the satellite magnet 901 (S pole) acts as an effective magnetic field from the A position to the C position, and the next satellite magnet 902 from the C position to the G position. The repulsive magnetic field F ₂ generated from the same polarity acts as an effective magnetic field. Next, in the step of repeating from the G position through the H position to the A position, the attractive magnetic field F ₁ of the next satellite magnet 903 (S pole) acts as an effective magnetic field. The C position and the G position serve as turning points for subsequent different effective magnetic fields, whereby the determination of the rotation direction of the satellite wheel 5 and the rotation assist for the drive wheel 3 are obtained.

When the satellite magnet 9 has a different polarity (S pole), each of the magnets 901, 903... Performs an arc motion operation by the rotation of the satellite wheel 5, but this operation is applied to the base magnet 7 because the mounting angle M is large. It approaches at a steep angle and moves away from the base magnet 7 at a steep angle. In both cases of approach and separation, the front end corner 9a is tilted forward. That is, when the satellite magnet 9 has a different polarity (S pole), the satellite magnet 9 approaches the base magnet 7 rapidly, and the approaching state is linear with respect to the base magnet 7. As a result, an attractive magnetic field F ₁ that suddenly increases or decreases in a short time is generated, whereby the rotation direction of the drive wheel 3 is determined.

  On the other hand, when the satellite magnet 9 has the same polarity (N pole), the arc motion of each of the magnets 902, 904... Gradually approaches the base magnet 7 and gradually from the base magnet 7 because the mounting angle L is small. To go away. This approach and separation are performed in a state where the front end corner portion 9a is expanded. That is, when the satellite magnet 9 has the same polarity (N pole), it gradually approaches the base magnet 7, and the approaching state is a planar posture with respect to the base magnet 7. As a result, a repulsive magnetic field that gradually increases for a long time is generated, thereby assisting the rotation of the drive wheel 3.

  The interaction between attraction and repulsion between the satellite magnet 9 and the base magnet 7 is based on the difference between the area and time exerted by the magnetic field, and the interaction between the attraction is instantaneous as shown schematically in the lower graph of FIG. The repulsive interaction takes a long time, resulting in a local effect just like the rotating magnetic field of an electric motor.

  As described above, the repulsive force is made larger than the attractive force by utilizing the characteristics of repulsion and attraction of the magnet, and the continuous interaction of magnetic attraction and repulsion due to mechanical conversion between the N pole and the S pole of the satellite wheel 5. Since the target repetition assists the rotation of the drive wheel 3, the load on the wheel shaft 45 linked to the drive wheel becomes as small as possible.

  The present invention is not limited to the above embodiments. For example, the induction drive wheel 1 is not prevented from being used alone.

  Further, the rotational speeds of the drive wheel 3 and the satellite wheel 5 are arbitrary, and the rotational speeds of both may be the same.

  The number of satellite wheels 5 may be plural, and is not limited to four. FIG. 9 shows a case where the number of satellite wheels 5 is eight.

The mounting angle of the satellite magnets only needs to be larger when the magnets of different polarity with respect to the base magnet are larger than the magnets of the same polarity, and the numerical values of the mounting angles M and L are not limited to the above examples. In the example of FIG. 9, the distances from the center O of rotation of the satellite wheel 5 to the front end corner 9a and the rear end corner 9b of the satellite magnet 902 of the same polarity and the front end corner 9a of the satellite magnet 901 of different polarity are all. It is equal to the radius r of the circumferential orbit of the satellite wheel, and the distance r ₃ from the center point O of rotation of the satellite wheel 5 to the rear end corner portion 9b of the satellite magnet 901 with a different polarity is shorter than this. In other words, the satellite magnets 902 having the same polarity are provided so that both end portions of the magnets are positioned on the rotation locus of the satellite wheel 5, and the satellite magnets 901 having different polarities are the base magnet 7 and the satellite magnet 901 that approaches the base magnet. When the positions of the front end corner portions 9a and 7a of the satellite magnets coincide with each other, the front end corner portion 9a of the satellite magnet is positioned on the rotation locus of the satellite wheel 5 and the rear end corner portion 9b is at a predetermined angle with respect to the tangent line T. Inclined with M (20 ° in the illustrated example).

  Appropriate materials can be used for the drive wheel 3, the satellite wheel 5, and the like.

  The base magnet 7 of the drive wheel 3 may be S-pole. In this case, the S-pole and N-pole mounting angles of the satellite magnet 9 of the satellite wheel 5 are opposite to those shown in the figure.

  Further, the carbon dioxide engine can be changed not only to the 5-sided rotor type but also to the 2-sided rotor type and the 3-sided rotor type.

  The circulating carbon dioxide engine system according to the present invention can be used for, for example, power generation, driving of automobiles, trains, airplanes, ships, etc., driving of motors, driving of generators.
