Abstract

The invention relates to a two-stroke cycle internal combustion heat engine having a connecting rod with indexed swash plates and an indexed mounted compressor. The two swash plates (15, 16) control the pistons (30, 31, 32) and are fixed at an angle α such that the exhaust-side piston (30) is always ahead of the transfer-side piston (31), thereby creating an asymmetry in the transfer/exhaust diagram. The cylinder (4) of the compresser is fixed at an angle β such that its piston (32) is disposed close to the top dead centre thererof when the transfer ports of the engine cylinder (1) have just been closed by the piston (31). In this way, fresh gases are delivered continuously during the entire transfer phase. As a result, the gas flush is optimised and the engine performs well over a wide rotation speed range. Under certain conditions, the inventive engine, which is light, compact and moderately complex, does not burn oil. Said engine is suitable for motorisation in relation to model making with light vehicles.

20 trique. Le balayage des gaz frais et chauds est critique, il en résulte un mauvais rendement et une faible plage efficace de vitesses de rotation.20 stick. The sweeping of cool and hot gases is critical, resulting in poor efficiency and a low effective range of rotational speeds.
Le moteur, sujet de la présente invention, par une ar- 25 chitecture originale, se propose d'apporter une solution pour optimiser le balayage des gaz frais et chauds. Par voie de conséquence, de proposer un bien meilleur rendement et une plus grande plage efficace de vitesses de rotation. Le premier objectif, est d'obtenir un diagramme asymétrique 30 à l'avance à l'ouverture et au retard à la fermeture des lumières d'échappement et de transfert. Le deuxième objectif est d'obtenir un soufflage continu des gaz frais durant toute la période d'ouverture des lumières de transfert.The engine, subject of the present invention, by an original architecture, proposes to provide a solution for optimizing the sweeping of fresh and hot gases. Consequently, to offer a much better efficiency and a greater effective range of rotational speeds. The first objective is to obtain an asymmetrical diagram 30 in advance at the opening and at the delay when the exhaust and transfer lights are closed. The second objective is to obtain a continuous blowing of the fresh gases throughout the opening period of the transfer lights.
Le premier objectif est atteint grâce à un embiellage à 35 deux plateaux oscillants portés par un même arbre principal Les pistons moteurs sont coaxiaux et tête-bêche, ils sont spécialisés, le piston moteur côté échappement pour ouvrir et fermer les lumières d'échappement, le piston moteur côté transfert pour ouvrir et fermer les lumières de transfert. Nota : La jupe des pistons moteurs ne décoiffe jamais les lumières d'échappement et de transfert. Les deux plateaux oscillants sont calés entre eux d'un angle α , de telle sorte, que le piston moteur côté échappement soit toujours en avance sur le piston moteur côté transfert, autrement dit, pour un angle d'ouverture identique aux lumières d'échappement et de transfert, les lumières d'échappement seront toujours ouvertes et refermées les premières. Cet embiellage à plateaux oscillants indexés a les avantages suivants : Le diagramme à l'avance à l'ouverture et au re- tard à la fermeture des lumières d'échappement et de transfert est bien asymétrique. En effet, les lumières de transfert seront encore ouvertes, alors que les lumières d'échappement seront déjà refermées, sous-entendu d'un choix judicieux de l'angle α et des angles d'ouvertures des lumières d'échappement et de transfert. Entre le moment où le piston moteur côté échappement vient de passer par son point mort haut et le moment où le piston moteur côté transfert va passer par son point mort haut, le volume de la chambre de combustion ne va pratiquement pas évoluer. Les pistons reprennent de faibles charges radiales. Les lumières de transfert étant refermées les dernières, un retour d'une onde de pression par le dispositif d'échappement n'est pas nécessaire et une suralimentation du moteur est envisageable. L'utilisation de plateaux oscillants comme embiellage n'est pas sans poser quelques problèmes. Le premier est de pouvoir piloter plusieurs pistons. Le deuxième est de pouvoir réaliser une liaison efficace entre les plateaux oscillants et les têtes de bielles, en sachant que sur un plateau oscillant, il existe deux positions remarquables où les têtes de bielles ont une trajectoire simple qui est plane et en arc de cercle. Toutes les autres positions possibles d'accrochage,, imprimeront aux têtes de bielles une trajectoire complexe en forme de huit en trois dimen- sions. Le troisième est de pouvoir lier un piston à une bielle dont la tête a une trajectoire complexe, en effet, ladite bielle à son pied oscillant avec en plus, un effet de rotation alternatif suivant son axe longitudinal. Le quatrième est de pouvoir stabiliser le plateau d'un plateau oscillant, afin qu'il ne tourne pas sur lui-même, et qu'il puisse reprendre les forces tangentielles induites par la poussée des pistons moteurs.The first objective is achieved thanks to a linkage to 35 two oscillating plates carried by the same main shaft The engine pistons are coaxial and head to tail, they are specialized, the engine piston on the exhaust side to open and close the exhaust lights, the engine piston on the transfer side to open and close the transfer lights. Note: The skirt of the engine pistons never messes up the exhaust and transfer lights. The two oscillating plates are wedged together at an angle α, so that the engine piston on the exhaust side is always ahead of the engine piston on the transfer side, in other words, for an opening angle identical to the exhaust lights and transfer, the exhaust lights will always be open and closed first. This connecting rod assembly with indexed oscillating plates has the following advantages: The diagram in advance at the opening and at the delay at closing of the exhaust and transfer lights is well asymmetrical. Indeed, the transfer lights will still be open, while the exhaust lights will already be closed, implying a judicious choice of the angle α and the opening angles of the exhaust and transfer lights. Between the moment when the engine piston on the exhaust side has just passed through its top dead center and the moment when the engine piston on the transfer side will go through its top dead center, the volume of the combustion chamber will practically not change. The pistons take up low radial loads. The transfer lights being closed last, a return of a pressure wave by the exhaust device is not necessary and an overfeeding of the engine is possible. The use of swashplates as a linkage is not without its problems. The first is to be able to control several pistons. The second is to be able to make an effective connection between the swash plates and the connecting rod heads, knowing that on a swash plate, there are two remarkable positions where the rod ends have a simple trajectory which is flat and in an arc. All other possible hooking positions, ,, will print a complex eight-shaped trajectory in three dimensions to the rod ends. The third is to be able to link a piston to a connecting rod whose head has a complex trajectory, in fact, said connecting rod at its oscillating foot with in addition, an effect of alternating rotation along its longitudinal axis. The fourth is to be able to stabilize the plate of an oscillating plate, so that it does not turn on itself, and that it can take up the tangential forces induced by the thrust of the engine pistons.
Le premier problème est solutionné par la conception suivante d'un plateau oscillant. Une bague d'oscillation est usinée d'un alésage incliné, le point de symétrie dudit alésage étant le centre d'oscillation, ledit alésage étant ajusté sur l'arbre principal. D'un plateau portant sur sa périphérie un ou plusieurs manetons, l'axe d'un maneton passant par le centre d'oscillation. Un dispositif glissant ou roulant forme une liaison à un degré de liberté en rotation entre la bague d'oscillation et le plateau. Le centre de gravité du plateau oscillant est confondu, à la tolérance près, avec son centre d'oscillation. Cette conception est compacte, rigide, équilibrée et peut proposer plusieurs manetons par plateau oscillant.The first problem is solved by the following design of a swash plate. An oscillation ring is machined from an inclined bore, the point of symmetry of said bore being the center of oscillation, said bore being adjusted on the main shaft. A plate carrying on its periphery one or more crank pins, the axis of a crank pin passing through the center of oscillation. A sliding or rolling device forms a connection with a degree of freedom in rotation between the oscillation ring and the plate. The center of gravity of the swash plate is confused, except for tolerance, with its center of oscillation. This design is compact, rigid, balanced and can offer several crankpins per swash plate.
Le deuxième problème est solutionné par l'utilisation de rotule à deux degrés de liberté en rotation, dite rotule à pistes de guidage. Une rotule à pistes de guidage est constituée d'une bague sphérique qui s'ajuste sur un mane- ton du plateau, d'un ou deux coussinets coiffants la portée sphérique de ladite bague sphérique et le ou lesdits coussinets étant fixés à une tête de bielle. L'un ou les deux coussinets sont pourvus de pistes de guidage, lesdites pistes de guidage viennent s'ajuster sur la partie basse ou haute ou sur les parties basses et hautes du maneton. La trajectoire desdites pistes de guidage reprend la même trajectoire mais légèrement amplifiée qu'à la ou les parties guidantes du maneton. Les pistes de guidage neutralisent un degré de liberté en rotation suivant l'axe longitudinal d'une bielle tout en permettant aux deux degrés de liberté en rotation restants, une amplitude de rotation au moins légèrement supérieure à l'angle d'oscillation des plateaux oscillants. Cette conception stabilise les têtes de bielles à trajectoire complexe. La forme prise par les surfaces sphériques de glissement des coussinets, minimise le jeu axial induit par le jeu radial normal de fonctionnement de la rotule à pistes de guidage.The second problem is solved by the use of a ball joint with two degrees of freedom in rotation, called a ball joint with guide tracks. A ball joint with guide tracks consists of a spherical ring which adjusts on a handle of the plate, of one or two bearings covering the spherical bearing of said spherical ring and the one or more bearings being fixed to a head of rod. One or both of the bearings are provided with guide tracks, said guide tracks come to adjust on the low or high part or on the low and high parts of the crank pin. The trajectory of said guide tracks takes up the same trajectory but slightly amplified as at the guide part or parts of the crankpin. The guide tracks neutralize a degree of freedom in rotation along the longitudinal axis of a connecting rod while allowing the two remaining degrees of freedom in rotation, an amplitude of rotation at least slightly greater than the angle of oscillation of the oscillating plates. . This design stabilizes the rod heads with complex trajectories. The shape taken by the spherical sliding surfaces of the bearings minimizes the axial play induced by the normal radial operating play of the ball joint with guide tracks.
Le troisième problème est solutionné par une rotule qui est tout à la fois, axiale et radiale, dite rotule mixte. Une rotule mixte a trois degrés de liberté en rotation, et peut reprendre des forces dans toutes les directions. La rotule mixte est constituée d'une bague sphérique à large portée et de un ou deux coussinets, eux-mêmes à larges portées, coiffants ladite bague sphérique. Il est à noter, que l'amplitude de l'oscillation d'un pied de bielle d'une bielle dont la tête a une trajectoire complexe, est toujours très faible, quelques degrés.The third problem is solved by a ball joint which is both axial and radial, called a mixed ball joint. A joint ball joint has three degrees of freedom in rotation, and can regain strength in all directions. The mixed ball joint consists of a spherical ring with a large span and one or two bearings, themselves with large spans, covering said spherical ring. It should be noted that the amplitude of the oscillation of a connecting rod foot of a connecting rod whose head has a complex trajectory is always very low, a few degrees.
Le quatrième problème est solutionné par l'utilisation de couples formés d'une bielle coulisseau et d'une cou- lisse. Une bielle coulisseau présente deux surfaces planes et parallèles de part et d'autre de sa tête, lesdites surfaces planes étant parallèles à l'axe longitudinal de ladite bielle coulisseau. La bielle coulisseau est ajustée glissante dans une coulisse. Ladite coulisse présente deux surfaces de glissement parallèles et vis-à-vis, ladite coulisse est dans le prolongement d'un cylindre moteur, elle est alignée avec la trajectoire des pistons moteurs, elle se place dans un carter d' embiellage. Le couple bielle coulisseau et coulisse reprend les forces tangentielles posi- tives ou négatives induites par le plateau du plateau oscillant quand un piston moteur pousse ou tire sur ledit plateau, il empêche ledit plateau de tourner sur lui-même, forçant ainsi la bague d'oscillation à entrer en rotation. Le couple bielle coulisseau et coulisse, n'élimine qu'un degré de liberté en translation et ne laisse qu'un degré de liberté en rotation, le tout, suivant la normale aux surfaces de glissement. Une bielle coulisseau est liée avantageusement au maneton du plateau oscillant par une rotule à pistes de guidage. Cette conception donne une trajectoire simple à la tête de la bielle coulisseau, rendant possible une liaison par un axe tubulaire entre le piston moteur et le pied de ladite bielle coulisseau. Nota : Il est possible d'installer deux bielles coulisseaux avec leurs coulisses par plateau oscillant, en notant, que les deux bielles cou- lisseaux doivent être diamétralement opposées.The fourth problem is solved by the use of couples formed by a slide rod and a slide. A slide rod has two flat and parallel surfaces on either side of its head, said flat surfaces being parallel to the longitudinal axis of said slide rod. The slide rod is adjusted sliding in a slide. Said slide has two parallel sliding surfaces and opposite, said slide is in the extension of a driving cylinder, it is aligned with the trajectory of the driving pistons, it is placed in a crankcase. The sliding rod and sliding rod couple takes up the positive or negative tangential forces induced by the plate of the plate oscillating when a driving piston pushes or pulls on said plate, it prevents said plate from turning on itself, thus forcing the oscillation ring to enter into rotation. The sliding rod and sliding rod couple eliminates only one degree of freedom in translation and leaves only one degree of freedom in rotation, all following the normal to the sliding surfaces. A sliding rod is advantageously linked to the crankpin of the swash plate by a ball joint with guide tracks. This design gives a simple trajectory to the head of the sliding rod, making possible a connection by a tubular axis between the driving piston and the foot of said sliding rod. Note: It is possible to install two slide rods with their slides by swash plate, noting that the two slide rods must be diametrically opposite.
Le deuxième objectif est atteint grâce à l'utilisation d'un compresseur à piston qui est rapporté au moteur et dont le volume est librement défini. Le compresseur est calé d'un angle β par rapport au cylindre moteur qui lui est associé, de façon que, ledit compresseur venant ou allant terminer sa phase de refoulement, à son piston compresseur encore proche ou sur son point mort haut, quand le piston moteur côté transfert du cylindre moteur associé audit compresseur, allant de son point mort bas vers son point mort haut, viendra tout juste de refermer les lumières de transfert. Le cylindre dudit compresseur intègre un dispositif d'admission à clapets libres et une tubulure de refoulement conduisant les gaz frais au regard des lumières de transfert du cylindre moteur associé audit compresseur. Le pis- ton compresseur est piloté par l'un des deux plateaux oscillants. Le compresseur est fixé à l'un des carters d' embiellage. L'axe du cylindre compresseur est parallèle à l'axe d'un cylindre moteur. Cette conception à compresseur rapporté et indexé a les avantages suivants : Le soufflage de gaz frais durant toute la phase de transfert est bien effectif. En effet, la phase de refoulement du compresseur commence peu de temps avant que le piston moteur côté transfert n'ouvre les lumières de transfert, ladite phase de refoulement se terminant quand le piston moteur côté transfert va complètement refermer les lumières de transfert. Les volumes morts au sein du compresseur et de la tubulure de refoulement sont faibles, la réaction à l'aspiration et au refoulement des gaz frais est très vive. Le coefficient de remplissage est constant sur une grande plage de vitesses de rotation. Le volume du compresseur étant librement défini, dudit volume va dépendre ledit coefficient de remplissage. La phase de « précompression » est de courte durée, le soufflage se fait à basse pression, la consommation de puissance en est réduite. L'association de l' embiellage à plateaux oscillants indexés et d'un compresseur rapporté indexé tels qu'ils viennent d'être décrits, propose bien un moteur disposant d'un balayage optimisé des gaz frais et chauds.The second objective is achieved through the use of a piston compressor which is attached to the engine and whose volume is freely defined. The compressor is set at an angle β relative to the associated engine cylinder, so that said compressor coming or going to end its delivery phase, with its compressor piston still close or on its top dead center, when the piston engine on the transfer side of the engine cylinder associated with said compressor, going from its bottom dead center to its top dead center, will just close the transfer lights. The cylinder of said compressor incorporates an inlet device with free valves and a discharge pipe leading the fresh gases with regard to the transfer lights of the engine cylinder associated with said compressor. The compressor piston is controlled by one of the two oscillating plates. The compressor is attached to one of the crankshaft housings. The axis of the compressor cylinder is parallel to the axis of an engine cylinder. This design with attached and indexed compressor has the following advantages: The blowing of fresh gas during the entire transfer phase is good effective. In fact, the discharge phase of the compressor begins shortly before the transfer side drive piston opens the transfer lights, said discharge phase ending when the transfer side drive piston completely closes the transfer lights. The dead volumes within the compressor and the discharge pipe are low, the reaction to the suction and discharge of the fresh gases is very strong. The filling coefficient is constant over a wide range of rotational speeds. The volume of the compressor being freely defined, said volume will depend on said filling coefficient. The “precompression” phase is short-lived, the blowing is done at low pressure, the power consumption is reduced. The combination of the connecting rod assembly with indexed oscillating plates and an indexed attached compressor as they have just been described, does indeed offer an engine having an optimized sweeping of fresh and hot gases.
La conception du moteur telle qu'elle vient d'être dé- crite ci-avant, oblige une préparation atypique dudit moteur. L' embiellage ne peut être pas graissé par un lubrifiant mélangé au carburant, la lubrification doit être propre à l' embiellage. Le lubrifiant utilisé pour le graissage de l' embiellage ne doit pas accéder à la chambre de combus- tion ni aux lumières d'échappement et de transfert. Les deux pistons moteurs d'un même cylindre moteur disposent de la même chambre de combustion.The design of the engine as it has just been described above, requires an atypical preparation of said engine. The crankshaft cannot be lubricated with a lubricant mixed with the fuel, the lubrication must be clean for the crankshaft. The lubricant used for the lubrication of the crankshaft must not reach the combustion chamber or the exhaust and transfer ports. The two engine pistons of the same engine cylinder have the same combustion chamber.
La première préparation consiste à faire circuler du lubrifiant sous faible pression dans l' embiellage. Des ba- gués de transfert d'huile via des raccords hydrauliques réalisent une liaison étanche en rotation entre les carters d' embiellage et l' embiellage, des réseaux de canaux forés dans les pièces constructives dudit embiellage, conduisent le lubrifiant entre toutes les surfaces glissantes et aux éléments roulants. Il est à noter que d'autres systèmes de graissage peuvent être utilisés, comme par exemple, le bar- botage ou la projection.The first preparation consists in circulating lubricant under low pressure in the connecting rod assembly. Oil transfer rods via hydraulic connections create a tight, rotational connection between the crankshaft housings and the crankshaft, networks of channels drilled in the construction parts of said crankshaft, conduct the lubricant between all the slippery surfaces and rolling elements. It should be noted that other lubrication can be used, for example, bubbling or projection.
La deuxième préparation consiste à équiper tous les pistons de segment racleur d'huile, lesdits segments placés sur les pistons moteurs étant toujours en dessous des lumières d'échappement et de transfert. La troisième préparation consiste à placer un ajutage à col au centre du cylindre moteur. Le diamètre du col est environ égal à la moitié du diamètre de l'alésage du cylindre moteur. Le volume du col, donc par extrapolation sa longueur, étant défini par le rapport volumétrique. La chambre de combustion ainsi obtenue est de moindre surface. Le rétrécissement au col de l'ajutage provoque de fortes turbulences dans la chambre de combustion à l'approche des deux pistons moteurs.The second preparation consists in equipping all the pistons with an oil scraper segment, said segments placed on the engine pistons being always below the exhaust and transfer ports. The third preparation consists in placing a neck nozzle in the center of the engine cylinder. The diameter of the neck is approximately equal to half the diameter of the bore of the engine cylinder. The volume of the neck, therefore by extrapolation of its length, being defined by the volumetric ratio. The combustion chamber thus obtained has a smaller surface area. The narrowing at the neck of the nozzle causes strong turbulence in the combustion chamber when approaching the two engine pistons.
L'ensemble du descriptif ci-avant peut s'appliquer à un moteur ayant deux variantes possibles. En nommant par entité motrice, l'association d'un ensemble moteur avec un ensemble compresseur : La première variante est un moteur avec une entité motrice. Un tube de liaison doit connecter les deux carters d' embiellage afin de minimiser les effets de pression et de dépression provoqués par l'arrière des pistons. Le moteur à un bon rapport Puissance/Masse, il a moins de pièces cons- tructives.The whole of the description above can be applied to an engine having two possible variants. By naming by motor entity, the association of an engine assembly with a compressor assembly: The first variant is an engine with a drive entity. A connecting tube should connect the two crankshaft housings to minimize the effects of pressure and depression caused by the rear of the pistons. The engine has a good Power / Weight ratio, it has fewer components.
La deuxième variante est un moteur avec deux entités motrices. Les axes des cylindres moteurs et l'axe de l'arbre principal appartiennent au même plan. Il n'y a pas de tube de liaison. Le moteur a un couple plus constant, il permet les fortes cylindrées.The second variant is an engine with two driving entities. The axes of the drive cylinders and the axis of the main shaft belong to the same plane. There is no connecting tube. The engine has a more constant torque, it allows strong displacements.

D'un piston moteur 30 côté échappement, d'un piston moteur 31 côté transfert et d'un piston compresseur 32. Il est à noter, que le piston moteur 30 côté échappement fonctionne dans des conditions sévères, contrairement au piston moteur 31 côté transfert, il n'est pas refroidi par la présence des gaz frais au niveau des lumières de transfert. La solution suivante a été retenue pour le piston moteur 30 côté échappement, un corps en alliage léger recouvert par une coiffe en cupro-alliage. En se référant à la figure 3, planche 2/6.

En se référant aux figures 9 et 10, planche 5/6. Des valeurs chiffrées vont être utilisées, il s'agit d'une solution possible parmi un grand nombre d'autre, qui va du moteur lent avec du couple au moteur rapide avec de la puissance, en passant par le moteur économique. Pour l'exemple proposé, les valeurs suivantes ont été utilisées : Un angle d'oscillation de 15° pour les deux plateaux oscillants, un calage aux plateaux oscillants α = 15°, un calage au compresseur β = 110°, un angle d'ouverture aux lumières d'échappement O.E.≈ 130°, un angle d'ouverture aux lumières de transfert O.T.= 115°, ω = 0 quand le piston moteur 30 côté échappement est au point mort bas. Nota : les deux plateaux oscillants peuvent avoir des angles d'oscillations différents. Les résultats suivants sont obtenus : Une avance à l'ouverture des lumières d'échappement A.O.E.= 295°, une avance à l'ouverture des lumières de transfert A.O.T.≈ 317.5°, soit entre l'ouverture des lumières d'échappement et l'ouverture des lumières de transfert, un décalage D.O.T.= 22.5°, ce qui donne du temps à l'évacuation des gaz chauds encore sous pression à l'ouverture des lumières d'échappement. Un retard à la fermeture des lumières d'échappement R.F.E.≈ 65°, un retard à la fermeture des lumières de transfert R.F.T.= 12. 5 ° , soit entre la fermeture des lumières d' échappement et la fermeture des lumières de transfert, un décalage D.F.T.≈ 7.5°, période pendant laquelle, des gaz frais vont continuer à être soufflés dans le cylindre moteur par les lumières de transfert, alors que les lumières d'échappement seront refermées par le piston moteur 30 côté échappement. Nota : il n'y a pas de diagramme spécifique pour la période d'admission, celle-ci étant régulée par des clapets libres 5 et donc variable en fonction des régimes moteurs. Le graphique figure 10 synthétise la cinématique d' un moteur avec une entité motrice. La courbe des espaces des pistons est très proche d'une sinusoïde. La courbe [A] en trait continu représente le piston moteur 30 côté échappement, la courbe [B] en trait pointillé représente le piston moteur 31 côté transfert, la courbe [C] en trait mixte représente le piston compresseur 32. La ligne en trait continu [D] représente la hauteur des lumières d'échappement. La ligne en trait pointillé [E] représente la hauteur des lumières de transfert. Le point [F] confirme qu'à la fermeture des lumières de transfert, que le piston compresseur 32 est très proche de son point mort haut. La zone [G] est le lieu où le volume de la chambre de combustion ne varie pratiquement pas, α est l'angle de calage entre les deux plateaux oscillants, β est l'angle de calage du compresseur.Referring to Figures 9 and 10, Plate 5/6. Numerical values will be used, it is a possible solution among a large number of others, which goes from the slow engine with torque to the fast engine with power, via the economical engine. For the example proposed, the following values were used: An angle of oscillation of 15 ° for the two oscillating plates, a setting with the oscillating plates α = 15 °, a setting with the compressor β = 110 °, an angle of opening to the exhaust lights OE lumières 130 °, an opening angle to the transfer lights OT = 115 °, ω = 0 when the engine piston 30 on the exhaust side is in bottom dead center. Note: the two oscillating plates can have different oscillation angles. The following results are obtained: An advance at the opening of the exhaust lights AOE = 295 °, an advance at the opening of the transfer lights AOT≈ 317.5 °, ie between the opening of the exhaust lights and the opening of the transfer lights, a DOT offset = 22.5 °, which gives time for the evacuation of hot gases still under pressure when the exhaust lights open. A delay in closing the RFE≈ 65 ° exhaust lights, a delay in closing the RFT transfer lights = 12.5 °, i.e. between the closing of the exhaust lights and the closing of the transfer lights, a time lag DFT≈ 7.5 °, period during which fresh gases will continue to be blown into the engine cylinder by the transfer lights, while the exhaust lights will be closed by the engine piston 30 on the exhaust side. Note: there is no specific diagram for the admission period, this being regulated by free valves 5 and therefore variable depending on the engine speeds. Graph 10 synthesizes the kinematics of an engine with a driving entity. The curve of the piston spaces is very close to a sinusoid. The curve [A] in solid line represents the engine piston 30 on the exhaust side, the curve [B] in dotted line represents the engine piston 31 on the transfer side, the curve [C] in broken line represents the compressor piston 32. The line in line continuous [D] represents the height of the exhaust lights. The dotted line [E] represents the height of the transfer lights. Point [F] confirms that when the transfer lights close, that the compressor piston 32 is very close to its top dead center. Zone [G] is the place where the volume of the combustion chamber practically does not vary, α is the setting angle between the two oscillating plates, β is the setting angle of the compressor.
En se référant à la figure 11, planche 6/6. Il s'agit d'un moteur avec deux entités motrices suivant la deuxième variante. Pour passer d'un moteur avec une entité motrice à un moteur avec deux entités motrices, il suffit de doubler ladite entité motrice telle qu'elle vient d'être présentée, de pratiquer quelques modifications mineures sur les carters, les cylindres et l' embiellage. Les axes des deux cylindres moteurs 1 et 60 et l'axe de l'arbre principal 14 appartiennent au même plan. Le moteur de la présente invention a une fabrication de complexité moyenne, il est léger, rigide et compact, il a un bon rendement et une large plage efficace de vitesses de rotation. Sa chambre de combustion est compatible avec un allumage commandé, ou un allumage par compression, ou un allumage par compression et point chaud. Une conception soignée des pistons moteurs avec par exemple, un revêtement antifriction, peut autoriser un fonctionnement sans ajout de lubrifiant dans le carburant, ainsi, le moteur ne brûlera pas d'huile. Le présent moteur peut convenir à la moto- risation qui va du modélisme aux véhicules légers. Referring to Figure 11, Plate 6/6. It is an engine with two driving entities according to the second variant. To switch from an engine with one drive unit to an engine with two drive units, it suffices to double said drive unit as it has just been presented, to make some minor modifications to the casings, the cylinders and the connecting rod assembly . The axes of the two engine cylinders 1 and 60 and the axis of the main shaft 14 belong to the same plane. The motor of the present invention has a manufacture of average complexity, it is light, rigid and compact, it has a good efficiency and a wide effective range of rotational speeds. Its combustion chamber is compatible with a controlled ignition, or a compression ignition, or a compression ignition and hot spot. A careful design of engine pistons with for example an anti-friction coating, can allow operation without adding lubricant to the fuel, thus, the engine will not burn oil. The present engine may be suitable for the motorization which ranges from model making to light vehicles.
