Description
Procédé et dispositif pour améliorer le fonctionnement de moteurs à explosion Method and device for improving the operation of internal combustion engines
Le fonctionnement des moteurs à explosion, en particulier pour véhicules automobiles, a été nettement perfectionné depuis quelques années, mais on s'est surtout attaché à améliorer l'alimentation en combustible et en comburant, considérant qu'il s'agissait d'un problème à résoudre en priorité, voire même le seul problème réel.The operation of internal combustion engines, in particular for motor vehicles, has been considerably improved in recent years, but the main emphasis has been on improving the fuel and oxidant supply, considering that this was a problem to be resolved as a priority, or even the only real problem.
C'est ainsi que l'on a adopté l'usage d'arbres à cames assurant une commande efficace des soupapes, puis le système d'injection en remplacement du carburateur, puis l'on a amélioré les conditions mêmes de l'explosion dans les chambres de combustion en prévoyant deux soupapes d'admission et deux soupapes d'échappement, soit quatre soupapes, par cylindre.This is how we adopted the use of camshafts ensuring effective control of the valves, then the injection system replacing the carburetor, then we improved the very conditions of the explosion in the combustion chambers by providing two intake valves and two exhaust valves, or four valves, per cylinder.
En ce qui concerne l'allumage, on a remplacé le distributeur à rupteur et vis platinées par un système d'allumage électronique mais il n'a toujours pas été remédié à un défaut constant du système d'alimentation électrique lui-même.As regards ignition, the distributor with breaker and platinum-plated screws has been replaced by an electronic ignition system, but a constant defect in the electrical supply system itself has still not been remedied.
En effet, si les générateurs de courant continu (dynamos) ont pratiquement disparu au profit des générateurs de courant alternatif (alternateurs), mais ceux-ci sont associés à un redresseur qui, finalement, fournit toujours du courant continu. Or, ce courant, après que sa tension ait été élevée, n'est pas continuellement adapté aux besoins variables d'un moteur à explosion, surtout quand il équipe un véhicule automobile, car le régime du moteur varie depuis son démarrage jusqu'à son arrêt, pendant les innombrables phases d'accélération, de décélération, de fonctionnement au ralenti, en charge variable, etc. Actuellement, la basse tension du courant issu du redresseur est porté à haute tension, soit par une bobine commune à toutes les bougies via un distributeur à rupteur, soit par une bobine individuelle à chaque cylindre.Indeed, if the direct current generators (dynamos) have practically disappeared in favor of the alternating current generators (alternators), but these are associated with a rectifier which, ultimately, always supplies direct current. However, this current, after its voltage has been high, is not continuously adapted to the variable needs of an internal combustion engine, especially when it is fitted to a motor vehicle, since the engine speed varies from its start to its stop during the countless phases of acceleration, deceleration, idling, variable load, etc. Currently, the low voltage of the current coming from the rectifier is brought to high voltage, either by a coil common to all the spark plugs via a valve distributor, or by an individual coil to each cylinder.
Dans un cas comme dans l'autre, la qualité de l'étincelle générée par chaque bougie doit toujours être maximale, que le moteur tourne au ralenti à vide ou qu'il tourne à son régime maximum et à pleine charge car chaque étincelle doit être capable de provoquer une explosion quasi instantanée du mélange carburant - comburant. Dès lors que la chambre de combustion a un volume invariable et que le mélange introduit
est toujours le même, l'étincelle devrait elle aussi être toujours la même, indépendamment du nombre de tours du moteur.In either case, the quality of the spark generated by each spark plug must always be maximum, whether the engine idles at idle or it runs at its maximum speed and at full load because each spark must be capable of causing an almost instantaneous explosion of the fuel - oxidizer mixture. As soon as the combustion chamber has an invariable volume and the mixture introduced is always the same, the spark should also always be the same, regardless of the number of revolutions of the engine.
Or, l'étincelle dépend des caractéristiques du courant et de la haute tension issus de la bobine correspondante et cette tension n'est pas invariable, de sorte que la combustion est elle-même irrégulière.However, the spark depends on the characteristics of the current and the high voltage from the corresponding coil and this voltage is not invariable, so that the combustion is itself irregular.
Il en résulte d'importantes irrégularités de combustion, conduisant à la création de résidus et d'imbrûlés qui ont les inconvénients cumulés d'augmenter inutilement la consommation de carburant et de rejeter à l'échappement des produits polluants atmosphériques. La présente invention remédie à ces inconvénients en permettant d'agir sur le courant à haute tension qui est issu de la ou de chaque bobine et qui est conduit à chaque bougie.This results in significant combustion irregularities, leading to the creation of residues and unburnt substances which have the cumulative disadvantages of unnecessarily increasing fuel consumption and rejecting exhaust air pollutants. The present invention overcomes these drawbacks by making it possible to act on the high voltage current which comes from the or each coil and which is led to each spark plug.
A cette fin, l'invention a pour objet un procédé pour améliorer la combustion de mélanges explosifs dans les moteurs à explosion, en particulier ceux qui équipent des véhicules, en agissant sur la qualité des arcs électriques d'allumage produits par des générateurs d'arcs électriques, ou « bougies » dans chaque chambre de combustion, caractérisé en ce que l'on stabilise la tension du courant électrique après qu'elle ait été élevée jusqu'à sa valeur nominale désirée pour le fonctionnement normal du moteur, et avant que le courant ait atteint les générateurs d'arcs électriques. L'invention a également pour objet un dispositif destiné à améliorer la combustion de mélanges explosifs dans les moteurs à explosion, en particulier ceux qui équipent des véhicules, et comprenant un circuit d'alimentation de courant électrique à haute tension caractérisé en ce qu'il comporte un stabilisateur de tension intercalé entre un générateur de haute tension ou « bobine » et les générateurs d'arcs électriques. D'autres caractéristiques de l'invention apparaîtront dans la description détaillée ci- après faite en référence au dessin annexé. Bien entendu, la description et le dessin ne sont donnés qu'à titre d'exemple indicatif et non limitatif.To this end, the subject of the invention is a method for improving the combustion of explosive mixtures in internal combustion engines, in particular those fitted to vehicles, by acting on the quality of the electric ignition arcs produced by generators of electric arcs, or "candles" in each combustion chamber, characterized in that the voltage of the electric current is stabilized after it has been raised to its desired nominal value for normal engine operation, and before the current has reached the electric arc generators.

La figure 7 est un schéma illustrant l'application de l'invention à un moteur non équipé d'un distributeur et ayant une bobine contrôlée électroniquement pour chaque bougie, un stabilisateur conforme à l'invention étant intercalé sur chaque conducteur allant d'une bobine à une bougie.FIG. 7 is a diagram illustrating the application of the invention to an engine not equipped with a distributor and having an electronically controlled coil for each spark plug, a stabilizer according to the invention being inserted on each conductor going from a coil to a candle.
Comme on l'a exposé dans le préambule de la présente description, la tension du courant alimentant les bougies d'un moteur devrait être stable mais ne l'est pas, en raison des différences considérables de régime du moteur. Pour que cette tension soit stable, il faudrait intercaler des résistances variables, contrôlées en permanence, ce qui n'est pas réalisable économiquement.As explained in the preamble to this description, the voltage of the current supplied to the spark plugs of an engine should be stable but is not, due to the considerable differences in engine speed. In order for this voltage to be stable, it would be necessary to insert variable resistors, permanently controlled, which is not economically feasible.
Par exemple, lorsqu'un moteur puissant de véhicule est lancé au démarreur, il serait nécessaire d'ajouter au circuit d'alimentation des bougies une résistance additionnelle qui, à courant constant, augmente la tension selon la classique loi d'Ohm :For example, when a powerful vehicle engine is started at the starter, it would be necessary to add to the spark plug supply circuit an additional resistance which, at constant current, increases the voltage according to the classic Ohm's law:
V = RIV = RI
égalité dans laquelle V est la tension, R la résistance du circuit et I le courant. Cette relation montre que plus la résistance R et/ou plus le courant I augmente(nt), plus la tension V augmente. Le courant ayant sensiblement une valeur constante, les variations de tensions observées avec tous les moteurs à explosion proviennent essentiellement des variations de résistance.
En régime de fonctionnement normal, cette résistance supplémentaire devient inutile et devrait être supprimée, mais il faudrait, de surcroît, que la valeur de cette résistance soit réglable et pilotée constamment, selon les variations de régime du moteur, sans pour autant apporter une solution au dépassement de la valeur nominale de tension puisque une résistance ne peut qu'augmenter la tension et non la réduire. Abaisser la valeur d'une résistance n'a pour effet que de diminuer l'augmentation de tension. L'allumage électronique qui existe maintenant sur la quasi totalité des véhicules automobiles, n'a aucun effet sur la tension du courant aboutissant à chaque bougie et l'on se contente de calibrer la bobine (ou chaque micro - bobine individuelle à chaque bougie) pour qu'elle amène la tension à une valeur prédéterminée, qui est de l'ordre de plusieurs dizaines de milliers de volts (35.000 V sur certaines voitures), sachant que les variations n'ont pas d'effet immédiatement perceptibles sur le fonctionnement du moteur. En réalité, le résultat de cette tension instable est une mauvaise combustion du mélange admis dans les cylindres, d'où une fatigue prématurée du moteur, une consommation de carburant inutilement élevée et un dégagement important d'imbrûlés et de résidus nocifs, provoquant la pollution de l'atmosphère. Selon l'invention, on stabilise la tension entre le ou les générateurs de tension élevée et les générateurs d'arcs électriques, c'est-à-dire entre la bobine unique et le distributeur habituel, ou entre chaque micro - bobine et la bougie correspondante. Pour cela, on intercale un ensemble condensateur - résistance qui absorbe les différences de tension par rapport à la tension de référence, soit en l'élevant, soit en l'abaissant. Sur les figures 1 et 2, on voit une installation classique, banale, qui ne fait pas partie de l'invention et qui est seulement destinée à illustrer la situation existante. On a choisi un moteur de voiture de tourisme mais il doit être bien compris que l'invention s'applique à tout moteur à explosion, quelle que soit son application : véhicules terrestres, avions, et engins volants légers, bateaux, machines diverses telles que les groupes électro gènes.
Le moteur A possède un distributeur B relié par des conducteurs isolés C à des bougies D. Une bobine E porte à une valeur élevée (de l'ordre des dizaines de milliers de Volts) un courant qui est apporté au distributeur B par un conducteur isolé F.equality in which V is the voltage, R the resistance of the circuit and I the current. This relation shows that the more the resistance R and / or the more the current I increases (nt), the more the voltage V increases. Since the current has a substantially constant value, the variations in voltages observed with all internal combustion engines come essentially from variations in resistance. In normal operating conditions, this additional resistance becomes unnecessary and should be eliminated, but it would also be necessary for the value of this resistance to be adjustable and controlled constantly, according to variations in engine speed, without however providing a solution to the problem. exceeding the nominal voltage value since a resistor can only increase the voltage and not reduce it. Lowering the value of a resistor only has the effect of decreasing the voltage increase. The electronic ignition which now exists on almost all motor vehicles has no effect on the voltage of the current leading to each spark plug and we simply calibrate the coil (or each individual micro-coil at each spark plug) so that it brings the voltage to a predetermined value, which is of the order of several tens of thousands of volts (35,000 V on certain cars), knowing that the variations have no immediately perceptible effect on the operation of the engine. In reality, the result of this unstable voltage is poor combustion of the mixture admitted into the cylinders, resulting in premature engine fatigue, unnecessarily high fuel consumption and significant release of unburnt and harmful residues, causing pollution. of the atmosphere. According to the invention, the voltage is stabilized between the high voltage generator (s) and the electric arc generators, that is to say between the single coil and the usual distributor, or between each micro-coil and the spark plug. corresponding. For this, a capacitor - resistor assembly is inserted which absorbs the voltage differences relative to the reference voltage, either by raising or lowering it. In Figures 1 and 2, we see a conventional installation, banal, which is not part of the invention and which is only intended to illustrate the existing situation. We chose a passenger car engine but it should be understood that the invention applies to any internal combustion engine, whatever its application: land vehicles, airplanes, and light flying vehicles, boats, various machines such as the generators. Motor A has a distributor B connected by insulated conductors C to spark plugs D. A coil E carries a high value (of the order of tens of thousands of volts) a current which is brought to distributor B by an insulated conductor F.
Comme dit plus haut, l'invention prévoit que l'on intercale un ensemble condensateur - résistance entre la bobine E et le distributeur B.As said above, the invention provides that a capacitor - resistance assembly is interposed between the coil E and the distributor B.
L'invention peut se concrétiser de différentes manières, notamment par intégration à des circuits électroniques plus ou moins complexes,The invention can be embodied in different ways, in particular by integration into more or less complex electronic circuits,
Mais une solution simple et avantageuse consiste à réaliser un ensemble 1 qui est représenté sur la figure 3 et qui comprend un boîtier isolant et étanche 2 contenant un circuit 3 comprenant les composants nécessaires pour assurer les fonctions de résistance et de capacité, montés en parallèle.However, a simple and advantageous solution consists in producing an assembly 1 which is shown in FIG. 3 and which comprises an insulating and sealed housing 2 containing a circuit 3 comprising the components necessary to perform the resistance and capacitance functions, mounted in parallel.
La figure 5 montre le schéma électrique de cet ensemble 1.Figure 5 shows the electrical diagram of this assembly 1.
Le circuit 3 comprend deux branches 4 et 5 dont les points communs respectivement 6 et 7 sont raccordés à un conducteur 8 et à un conducteur 9 placés dans une gaine isolante pour constituer un câble étanche et flexible.The circuit 3 comprises two branches 4 and 5, the common points respectively 6 and 7 of which are connected to a conductor 8 and to a conductor 9 placed in an insulating sheath to constitute a sealed and flexible cable.
Chacune des extrémités des conducteurs 8 et 9 est raccordée à un connecteur conducteur respectivement 10 et 11, entouré d'un manchon isolant 12 - 13.Each of the ends of the conductors 8 and 9 is connected to a conductive connector respectively 10 and 11, surrounded by an insulating sleeve 12 - 13.
Sur la branche 4 du circuit 3 on a figuré un condensateur 14 et sur la branche 5 on a figuré une résistance 15. Avec cet ensemble 1, il est possible d'équiper non seulement les moteur neufs, lors de leur fabrication, mais aussi les moteurs préexistants, plus ou moins usagés.On branch 4 of circuit 3 there has been shown a capacitor 14 and on branch 5 there has been shown a resistor 15. With this assembly 1, it is possible to equip not only the new engines, during their manufacture, but also the pre-existing engines, more or less used.
En effet, il suffit de retirer le câble existant F et de le remplacer par l'ensemble 1 dont on place l'embout 10-12 sur la borne de la bobine E et l'embout 11-13 sur la borne du distributeur B. Le condensateur 14 peut être du type à huile, calibré pour une tension de 600 à 1 000Indeed, it suffices to remove the existing cable F and replace it with the assembly 1, the end piece 10-12 of which is placed on the terminal of the coil E and the end piece 11-13 on the terminal of the distributor B. The capacitor 14 can be of the oil type, calibrated for a voltage of 600 to 1000
Volts, tel que connu sous l'appellation de « point 1 », couramment utilisée dans la nomenclature internationale.Volts, as known as "point 1", commonly used in international nomenclature.
La résistance est avantageusement de 680 à 720 Ω et de 1 à 3 Watts selon les moteurs, sachant que la plupart des moteurs existants actuellement appellent une puissance de 2 Watts, ce qui les met à l'abri de chocs électriques et de contraintes excessives.The resistance is advantageously from 680 to 720 Ω and from 1 to 3 Watts depending on the motors, knowing that most of the existing motors currently call for a power of 2 Watts, which shelters them from electric shocks and excessive stresses.
Un tel circuit 3 est en mesure de s'opposer à toute variation significative de la haute tension du courant issu de la bobine E.
En conséquence, le distributeur B puis les bougies D reçoivent une tension stabilisée, qui permet de générer des arcs électriques (ou « étincelles ») régulières et de caractéristiques constantes, exactement conformes à ce qui conçu par le fabricant du moteur.Such a circuit 3 is able to oppose any significant variation in the high voltage of the current from the coil E. Consequently, the distributor B then the spark plugs D receive a stabilized voltage, which makes it possible to generate electric arcs (or "sparks") regular and of constant characteristics, exactly in accordance with what designed by the manufacturer of the engine.
De ce fait, la combustion du mélange carburant - comburant est elle-même régulière, sans avance ni retard par rapport à l'admission de ce mélange, ce qui assure une bonne longévité au moteur puisqu'il ne risque pas de s'encrasser, ni de subir des contraintes d'usure ; la consommation de carburant est minimum, exactement égale à ce qu'elle doit être, sans dépassement ni déperdition. Il se produit peu d'imbrûlés et peu de résidus polluants.As a result, the combustion of the fuel-oxidizer mixture is itself regular, with no advance or delay with respect to the admission of this mixture, which ensures good longevity for the engine since it does not risk clogging, nor to undergo wear stresses; fuel consumption is minimum, exactly equal to what it should be, without overshoot or loss. There are few unburnt products and few polluting residues.
Des moteurs modernes G n'ont plus de distributeur, et chaque bougie D reçoit le courant à haute tension directement de la bobine E, ce que l'on a représenté sur la figure 6. La bobine E a autant de bornes de distribution qu'il y a de bougies D et un dispositif électronique H contrôle la bobine E pour que l'alimentation des bougies D se fasse par séquences, ce que l'on a simplement schématisé par un rectangle en traits mixtes.Modern engines G no longer have a distributor, and each spark plug D receives the high-voltage current directly from the coil E, which is shown in FIG. 6. The coil E has as many distribution terminals as there are spark plugs D and an electronic device H controls the coil E so that the candles D are supplied in sequence, which we have simply schematized by a rectangle in dashed lines.
Avec cette structure, la bobine E est reliée aux bougies D par des ensembles 1 comprenant chacun un boîtier 2 et des conducteurs 8 et 9. D'autres moteurs I n'ont pas une bobine et un distributeur mais la tension d'alimentation des bougies D devant être élevée, il est toujours nécessaire d'élever la tension et cela est alors obtenu avec une microbobine J individuelle à chaque bougie D. Dans ce cas, il n'y a pas de distributeur de courant à haute tension puisqu'il n'y a pas une seule bobine pour plusieurs bougies. Mais il faut toujours que chaque bougie D entre en action à un moment précis, qui correspond au remplissage de la chambre de combustion et à la compression maximale du mélange admis, et cela pour tous les cylindres du moteur I successivement dans un ordre précis. Le moteur I comporte alors une liaison directe entre chaque microbobine J et chaque bougie D, ce que schématise la figure 7.With this structure, the coil E is connected to the spark plugs D by assemblies 1 each comprising a housing 2 and conductors 8 and 9. Other motors I do not have a coil and a distributor but the supply voltage of the spark plugs D must be high, it is always necessary to raise the voltage and this is then obtained with an individual microbool J at each spark plug D. In this case, there is no high voltage current distributor since there there is not a single coil for several candles. But it is always necessary that each spark plug D comes into action at a specific time, which corresponds to the filling of the combustion chamber and to the maximum compression of the admitted mixture, and this for all the cylinders of the engine I successively in a precise order. The engine I then has a direct connection between each microbool J and each spark plug D, which is shown diagrammatically in FIG. 7.
Selon l'invention, un ensemble 1 est prévu pour chaque couple microbobine J - bougie D mais dans la pratique, les conducteurs 8 et 9 peuvent avoir une longueur très
réduite, voire nulle si l'on monte les boîtiers 2 au contact des microbobines J d'une part et aux bougies D d'autre part, l'important étant simplement que le circuit 3 soit électriquement intercalé entre chaque microbobine J (ou générateur de haute tension) et chaque bougie D (ou générateur d'arcs électriques).According to the invention, a set 1 is provided for each microbool J - spark plug D pair, but in practice, the conductors 8 and 9 can be very long. reduced, or even zero if the boxes 2 are mounted in contact with the microbins J on the one hand and with the spark plugs D on the other hand, the important thing is simply that the circuit 3 is electrically interposed between each microbool J (or generator high voltage) and each spark plug D (or generator of electric arcs).
