Abstract

This device comprises a turbocompressor C whose turbine 7 has a scroll 8a connected to two pipes 5, 6 each connected to the exhaust of a group of cylinders of the engine. The inlet of the scroll is divided by a partition 10 into two conduits 11, 12 which extend the two pipes 5, 6. A regulating flap 15 is provided and constitutes a movable wall of the scroll and includes two extensions 18, 19 which extend on each side of the partition 10 into the conduits 11, 12. This arrangement avoids the phenomenon of a counter-scavenging in the cylinders of the engine and improves the efficiency of the turbine.

Description

L'invention se rapporte à un dispositif permettant d'assurer la suralimentation d'un moteur à combustion interne au moyen d'un turbo-compresseur unique.The invention relates to a device for ensuring the supercharging of an internal combustion engine by means of a single turbo-compressor.

Dans les moteurs à combustion interne à quatre cylindres suralimentés par un turbo-compresseur unique à roue radiale, raccordé sur un collecteur unique d'échappement, il est bien connu qu'il existe une difficulté de vidange des fonds de cylindres, en particulier aux vitesses élevées.In internal combustion engines with four cylinders supercharged by a single turbo-compressor with radial wheel, connected to a single exhaust manifold, it is well known that there is a difficulty in draining the bottoms of cylinders, in particular at speeds high.

Ce phénomène peut s'expliquer de la manière suivante: lorsque le piston d'un cylindre est au voisinage de son point mort haut et que commence la phase d'admission, le cylindre suivant dans l'ordre d'allumage est déjà en cours de vidange, du fait de l'avance habituelle de l'ouverture de sa soupape d'échappement, et la bouffée d'échappement provoque une remontée de pression, dans l'ensemble du collecteur des gaz. Cette pointe de pression qui se fait sentir alors que la soupape d'échappement du cylindre considéré est encore ouverte, provoque un contre-balayage qui est dommageable à son remplissage et qui accentue les contraintes thermiques, limitant ainsi une utilisation plus intensive du moteur.This phenomenon can be explained as follows: when the piston of a cylinder is near its top dead center and the intake phase begins, the next cylinder in the ignition order is already being emptying, due to the usual advance of the opening of its exhaust valve, and the exhaust puff causes a rise in pressure in the entire gas manifold. This pressure surge which is felt while the exhaust valve of the cylinder in question is still open, causes a counter-sweep which is damaging to its filling and which accentuates the thermal stresses, thus limiting more intensive use of the engine.

On connaît déjà plusieurs solutions qui permettent de remédier à cet inconvénient.Several solutions are already known which make it possible to remedy this drawback.

On peut, par exemple, utiliser deux turbocompresseurs séparés, dans chacun desquels débite un groupe de cylindres suffisamment espacés les uns des autres dans l'ordre d'allumage. Cette solution a l'inconvénient d'être chère et de conduire à un mauvais rendement moyen de la turbine qui n'est pas alimentée pendant une partie du temps, par exemple à peu près la moitié du temps avec un moteur à quatre cylindres.One can, for example, use two separate turbochargers, in each of which delivers a group of cylinders sufficiently spaced from each other in the order of ignition. This solution has the disadvantage of being expensive and leading to poor average efficiency of the turbine which is not supplied for part of the time, for example about half the time with a four-cylinder engine.

On peut aussi utiliser une turbine unique à double volute, chaque volute étant alimentée comme dans le cas précédent. Cette solution ne donne pas pleinement satisfaction car elle ne permet pas une baisse suffisante de pression dans la volute non alimentée lors de la pointe dans la volute alimentée. D'autre part, l'encombrement d'une turbine à deux volutes est plus important que l'encombrement d'une turbine à volute unique.It is also possible to use a single double volute turbine, each volute being supplied as in the previous case. This solution does not give full satisfaction because it does not allow a sufficient drop in pressure in the unpowered volute during the peak in the supplied volute. On the other hand, the size of a turbine with two scrolls is more important than the size of a turbine with a single scroll.

On a également utilisé un «convertisseur de bouffées », ou « pulse converter», composé de deux tuyères alimentées successivement par des cylindres convenablement décalés dans l'ordre d'allumage et suivies d'un conduit formant éventuellement diffuseur, raccordé sur l'entrée d'une turbine unique. Si la section des tuyères est suffisamment réduite, on peut obtenir dans le collecteur non alimenté une baisse de pression satisfaisante, mais cet agencement présente le double inconvénient de provoquer une perte d'énergie dans les tuyères et de n'être efficace que dans des limites étroites de régime du moteur, ce qui fait qu'il est inadapté aux applications automobiles.We also used a "puff converter", or "pulse converter", composed of two nozzles successively supplied by cylinders suitably offset in the ignition order and followed by a conduit possibly forming a diffuser, connected to the inlet of a single turbine. If the cross section of the nozzles is sufficiently reduced, a satisfactory pressure drop can be obtained in the non-supplied manifold, but this arrangement has the double disadvantage of causing a loss of energy in the nozzles and of being effective only within limits. narrow engine speed, which makes it unsuitable for automotive applications.

Le brevet DE-A No 2143696 décrit un tel convertisseur de bouffées, à section réglable, comportant une volute dont l'entrée, prolongée vers l'amont, est divisée en deux conduits munis chacun d'un volet de réglage. La section de la turbine proprement dite demeure cependant fixe. De plus, dans cet agencement antérieur, le volet est disposé de telle façon que les gaz sont projetés vers l'extérieur de la volute où il est bien connu que les vitesses sont normalement plus faibles qu'au voisinage immédiat de la roue. Il se produit donc une explosion de la veine à la sortie des sections rétrécies du convertisseur de bouffées et une perte de rendement importante. L'invention se propose d'apporter une solution plus efficace au problème exposé ci-dessus et de fournir un dispositif de suralimentation qui soit satisfaisant pour tous les régimes de fonctionnement du moteur.Patent DE-A No. 2143696 describes such a puff converter, with adjustable section, comprising a volute whose inlet, extended upstream, is divided into two conduits each provided with an adjustment flap. However, the section of the turbine itself remains fixed. In addition, in this prior arrangement, the flap is arranged in such a way that the gases are projected towards the outside of the volute where it is well known that the speeds are normally lower than in the immediate vicinity of the wheel. There is therefore an explosion of the vein at the outlet of the narrowed sections of the puff converter and a significant loss of efficiency. The invention proposes to provide a more effective solution to the problem set out above and to provide a supercharging device which is satisfactory for all engine operating conditions.

Elle s'applique à un dispositif de suralimentation pour moteur à combustion interne comprenant un turbo-compresseur dont la turbine comporte une volute apte à être raccordée à deux tubulures reliées chacune aux échappements d'un groupe de cylindres du moteur, l'entrée de la volute étant divisée par une cloison en deux conduits qui sont aptes à prolonger les deux tubulures et qui sont munis chacun d'un organe de réglage. Ce dispositif est caractérisé en ce que lesdits organes de réglage sont constitués par deux prolongements d'un volet de réglage comportant une surface concave qui constitue une paroi mobile de la volute.It applies to a supercharging device for an internal combustion engine comprising a turbo-compressor, the turbine of which comprises a volute capable of being connected to two pipes each connected to the exhausts of a group of cylinders of the engine, the inlet of the volute being divided by a partition into two conduits which are able to extend the two pipes and which are each provided with an adjustment member. This device is characterized in that said adjustment members are constituted by two extensions of an adjustment flap comprising a concave surface which constitutes a movable wall of the volute.

Suivant d'autres caractéristiques:

  • - la cloison est formée par une toile de section transversale triangulaire dont la pointe est dirigée vers l'aval de la volute;
  • - le volet articulé sur le corps de la turbine autour d'un axe comporte au moins une surface cylindrique de section circulaire centrée sur cet axe, coopérant avec une surface conjuguée ménagée dans le corps de la turbine;
  • - il est prévu deux jeux de surfaces conjuguées, respectivement amont et aval.
According to other characteristics:
  • - the partition is formed by a fabric of triangular cross section whose point is directed downstream of the volute;
  • the flap articulated on the body of the turbine around an axis comprises at least one cylindrical surface of circular section centered on this axis, cooperating with a conjugate surface formed in the body of the turbine;
  • - Two sets of conjugate surfaces are provided, respectively upstream and downstream.

L'invention a également pour objet un moteur suralimenté équipé d'un tel dispositif.The invention also relates to a supercharged engine equipped with such a device.

Un exemple de réalisation fait l'objet de la description qui suit, en référence aux dessins joints dans lesquels:

  • la fig. 1 est une coupe suivant un plan perpendiculaire à son axe de rotation, d'une turbine agencée selon l'invention;
  • la fig. 2 est un schéma de raccordement sur un moteur, avec coupe partielle selon fa ligne 2-2 de la fig. 1 ;
  • la fig. 3 est une coupe selon la ligne 3-3 de la fig. 1.
An exemplary embodiment is the subject of the following description, with reference to the accompanying drawings in which:
  • fig. 1 is a section along a plane perpendicular to its axis of rotation, of a turbine arranged according to the invention;
  • fig. 2 is a connection diagram on a motor, with partial section along line 2-2 of FIG. 1;
  • fig. 3 is a section along line 3-3 of FIG. 1.

On a représenté schématiquement sur la fig. 2 un moteur M à combustion interne comportant quatre cylindres 1, 2, 3 et 4 et, en partie, un turbo-compresseur C.There is shown schematically in FIG. 2 an internal combustion engine M comprising four cylinders 1, 2, 3 and 4 and, in part, a turbo-compressor C.

Les gaz d'échappement du moteur sont canalisés vers deux tubulures 5 et 6 alimentées par des cylindres différents convenablement choisis dans l'ordre d'allumage de manière que, pour chaque tubulure, les cylindres qui s'y raccordent soient décalés d'un angle d'au moins 220° mesurés sur le vilebrequin du moteur. Dans le cas représenté d'un moteur à quatre cylindres dont l'ordre d'allumage est 1, 3, 4, 2, la tubulure 5 est raccordée sur les cylindres 1 et 4, tandis que la tubulure 6 est raccordée sur les cylindres 2 et 3.The engine exhaust gases are channeled to two pipes 5 and 6 supplied by different cylinders suitably chosen in the order of ignition so that, for each pipe, the cylinders which are connected to them are offset by an angle at least 220 ° measured on the engine crankshaft. In the case shown of a four-cylinder engine whose ignition order is 1, 3, 4, 2, the pipe 5 is connected to the cylinders 1 and 4, while the tubing 6 is connected to cylinders 2 and 3.

Les tubulures 5 et 6 sont reliées à une turbine radiale 7 dont le corps 8 délimite une volute 8a dans laquelle tourne une roue 9 qui entraîne un compresseur non représenté.Tubing 5 and 6 are connected to a radial turbine 7, the body 8 of which delimits a volute 8a in which a wheel 9 rotates which drives a compressor, not shown.

L'entrée de la volute 8a est divisée, par une toile 10, en deux conduits 11, 12, qui constituent des prolongements des tubulures 5 et 6, respectivement. La toile 1 0 a une section transversale à peu près triangulaire et se termine, vers l'aval, par une arête 13 qui se situe en amont par rapport à une section S de la volute 8a passant par son bec théorique 14, de manière que la volute puisse être remplie convenablement à partir du jet de gaz provenant de chacune des tubulures 5 et 6.The inlet of the scroll 8a is divided, by a fabric 10, into two conduits 11, 12, which constitute extensions of the pipes 5 and 6, respectively. The fabric 1 0 has a roughly triangular cross section and ends, downstream, by an edge 13 which is located upstream with respect to a section S of the volute 8a passing through its theoretical beak 14, so that the volute can be properly filled from the gas jet coming from each of the pipes 5 and 6.

Un volet 15, reçu dans un logement latéral 8b du corps 8, est articulé sur ce corps autour d'un axe 16. Il comporte une surface 17, de préférence concave, qui constitue une paroi mobile de la volute permettant de régler sa section d'entrée en fonction des conditions par tout moyen connu, par exemple à l'aide d'une tige 15a d'axe Y ou à l'aide d'un levier agissant directement sur l'axe 16.A flap 15, received in a lateral housing 8b of the body 8, is hinged to the body about an axis 16. It includes a surface 17, preferably concave, which forms a movable wall of the volute for adjusting its cross section input depending on the conditions by any known means, for example using a rod 15a of axis Y or using a lever acting directly on axis 16.

Le volet 15 comporte deux prolongements 18, 19 pénétrant respectivement à l'intérieur des conduits 11 et 12. Ces prolongements 18, 19 sont séparés par une fente 20 laissant le passage pour la toile 10 qui se prolonge latéralement en 1 Oa dans le logement 8b. Ils sont terminés, chacun, par une surface cylindrique 21 de section circulaire centrée sur l'axe 16 et coopérant avec une surface conjuguée 22 formée dans le logement 8b, afin d'assurer une étanchéité au moins approximative vers l'amont du volet. De même, une étanchéité au moins approximative est assurée vers l'aval du volet, par coopération entre deux surfaces 23, 24, centrées sur l'axe 16 et formées respectivement sur le volet 15 et dans la volute 8a.The flap 15 has two extensions 18, 19 respectively penetrating inside the conduits 11 and 12. These extensions 18, 19 are separated by a slot 20 leaving the passage for the fabric 10 which extends laterally at 1 Oa in the housing 8 b . They are terminated, each, by a cylindrical surface 21 of circular section centered on the axis 16 and cooperating with a conjugate surface 22 formed in the housing 8b , in order to ensure at least approximate sealing upstream of the shutter. Likewise, at least approximate sealing is ensured downstream of the shutter, by cooperation between two surfaces 23, 24, centered on the axis 16 and formed respectively on the shutter 15 and in the volute 8a.

Grâce à l'agencement qui vient d'être décrit, on peut, à l'aide d'une seule pièce actionnée par un seul mécanisme, régler à la fois la section d'entrée de la volute 8a et les sections d'arrivée des gaz dans les tubulures 5 et 6, à leur débouché dans la volute.Thanks to the arrangement which has just been described, it is possible, using a single piece actuated by a single mechanism, to adjust both the inlet section of the volute 8a and the inlet sections of the gas in the pipes 5 and 6, at their outlet in the volute.

De cette façon, les sections terminales des tubulures 5 et 6 et la section d'entrée de la volute 8a sont constamment adaptées au débit des gaz d'échappement. On peut ainsi, pour tous les régimes du moteur, obtenir, d'une part, une baisse de pression suffisamment réduite dans celle 5 ou 6 des tubulures qui n'est pas alimentée en gaz d'échappement, ce qui évite l'inconvénient du contre-balayage dans les cylindres, et, d'autre part, un bon rendement de la turbine quel que soit le débit des gaz, ce qui permet, notamment, d'améliorer la suralimentation à bas régime. Il s'ensuit qu'il devient inutile de prévoir une soupape de by pass, tandis qu'une telle soupape est indispensable, habituellement, pour évacuer les gaz en excès lorsque la vitesse du moteur devient importante. Avec l'agencement de l'invention, tous les gaz travaillant dans la turbine, il en résulte un meilleur rendement général.In this way, the end sections of the pipes 5 and 6 and the inlet section of the volute 8a are constantly adapted to the flow of the exhaust gases. It is thus possible, for all engine speeds, to obtain, on the one hand, a sufficiently reduced pressure drop in that 5 or 6 of the pipes which is not supplied with exhaust gas, which avoids the disadvantage of against sweeping in the cylinders, and, on the other hand, good efficiency of the turbine whatever the gas flow rate, which makes it possible, in particular, to improve the supercharging at low speed. It follows that it becomes unnecessary to provide a bypass valve, while such a valve is essential, usually, to evacuate excess gases when the engine speed becomes important. With the arrangement of the invention, all the gases working in the turbine, this results in a better general efficiency.

Par ailleurs, l'énergie cinétique des jets de gaz au débouché des conduits 5 et 6 peut être aussi élevée que nécessaire, sans qu'il en résulte de perte sensible, puisque cette énergie est directement utilisée dans la roue 9 et que les gaz sont toujours dirigés au plus près de la roue.Furthermore, the kinetic energy of the gas jets at the outlet of the conduits 5 and 6 can be as high as necessary, without this resulting in significant loss, since this energy is directly used in the wheel 9 and the gases are always directed as close as possible to the wheel.

Il va de soi que l'invention s'applique de la même façon si le volet 15 est suivi vers l'aval, ainsi qu'il est connu, par un ou plusieurs autres volets mobiles destinés à allonger la zone de la volute sur laquelle se fait le réglage de la section.It goes without saying that the invention applies in the same way if the flap 15 is followed downstream, as is known, by one or more other movable flaps intended to lengthen the area of the volute on which the section is adjusted.
