The feed device further comprises an uncooled bypass circuit connected to the main circuit on either side of the charge air cooler. Valves are mounted on the main circuit and the bypass circuit and controlled by the engine control unit (ECU) to direct the air to either circuit so as to get into the intake manifold. an air temperature adapted to the desired performance of the engine.
Ce système ne permet cependant pas toujours d'obtenir un fonctionnement optimal du moteur, notamment au démarrage et au ralenti.However, this system does not always make it possible to obtain optimal operation of the engine, especially at start-up and at idle speed.
OBJET DE L ' INVENTIONOBJECT OF THE INVENTION
Un but de 1 ' invention est de fournir un moyen pour améliorer le fonctionnement du moteur.An object of the invention is to provide a means for improving the operation of the engine.
RESUME DE L ' INVENTION A cet effet, on prévoit, selon l'invention, un dispositif d'admission d'air d'un moteur thermique comportant :SUMMARY OF THE INVENTION For this purpose, according to the invention, an air intake device of a heat engine comprising:
- un circuit principal qui relie un organe de suralimentation à un collecteur d'admission et qui incor- pore un échangeur thermique, - un circuit dérivé relié au circuit principal de part et d'autre de l'échangeur, le circuit dérivé incorporant un organe de chauffage,a main circuit which connects a supercharger to an intake manifold and which incorporates a heat exchanger, a derivative circuit connected to the main circuit on either side of the exchanger, the derived circuit incorporating a heating element,
- un organe de sélection du circuit monté entre le circuit principal et le circuit dérivé pour diriger au moins en partie l'air dans l'un ou l'autre circuit.- A circuit selection member mounted between the main circuit and the branch circuit for directing at least part of the air in one or the other circuit.
L'organe de chauffage permet d'augmenter la température de l'air, facilitant ainsi le démarrage du moteur et stabilisant le fonctionnement du moteur au ralen- ti . Les plages de température qu'il est possible d'obtenir dans la tubulure d'admission sont augmentées.The heating element makes it possible to increase the temperature of the air, thus making it easier to start the engine and stabilizing the operation of the engine in slow motion. The temperature ranges that can be obtained in the intake manifold are increased.

The bypass air circuit 109 is connected to the main circuit 105 directly downstream of the air cooling. a supercharger and a valve 99 upstream of the charge air cooler.
En référence aux figures 1 à 7, la vanne 99 utilisée dans ce mode de réalisation de 1 ' invention comprend un corps généralement désigné en 1 délimitant un premier conduit 3 et un deuxième conduit 4 débouchant dans un troisième conduit 2. Le premier conduit 3 est relié au circuit dérivé 109. Le deuxième conduit 4 et le troisième conduit 5 sont reliés au circuit principal 105, le deuxième conduit 4 étant relié au refroidisseur d'air de suralimentation et le troisième conduit 5 au compresseur. Le corps 1 et les conduits 3 et 4 ne sont représentés qu'en partie sur les figures 5 à 7. Sur la figure 8, on voit que le corps 1 est relié à la partie supérieure des cylindres 101 par un organe de dissipation thermique 111 formé d'une pièce en matériau thermiquement conducteur.With reference to FIGS. 1 to 7, the valve 99 used in this embodiment of the invention comprises a body generally designated at 1 delimiting a first duct 3 and a second duct 4 opening into a third duct 2. The first duct 3 is connected to the bypass circuit 109. The second duct 4 and the third duct 5 are connected to the main circuit 105, the second duct 4 being connected to the charge air cooler and the third duct 5 to the compressor. The body 1 and the ducts 3 and 4 are only partially represented in FIGS. 5 to 7. In FIG. 8, it can be seen that the body 1 is connected to the upper part of the cylinders 101 by a heat dissipating member 111 formed of a piece of thermally conductive material.
Le premier conduit 3 est équipé d'un premier volet double ou papillon 5 solidaire d'un axe 6 monté pour pivoter sur le corps 1. L ! axe 6 comprend une extrémité s ' étendant en saillie du corps 1 et solidaire en rotation d'une première roue de transmission 7, dentée, en prise avec un engrenage intermédiaire 8 lui-même en prise avec un pignon 9 solidaire d'un arbre de sortie d'un moteur 10 monté sur le corps 1. Le moteur 10 est un moteur a courant continu connu en lui-même relié à une source d'éner- gie électrique et à un module de commande qui sont également connus en eux-mêmes et ne sont pas représentés sur les figures. Un ressort de torsion 11 s'étend hélicoïda- lement autour de ladite extrémité de l'axe 6 en ayant une extrémité reliée à la roue de transmission 7 et une ex- trémité reliée au corps 1. Le ressort 11 rappelle le pa- pilion 5 en position d'ouverture (représentée sur les figures 2 à 4) . La roue de transmission 7 est pourvue d'ergots 12, 13 qui sont destinés à coopérer avec une butée 14 solidaire du corps 1. Lorsque l'ergot 12 est en butée contre la butée 14, le papillon 5 est dans une première position de fermeture (représentée sur la figure 6) et, lorsque l'ergot 13 est en appui contre la butée 14, le papillon 5 est dans une deuxième position de fermeture (représentée sur la figure 7) . Le papillon 5 est sensi- blement perpendiculaire au conduit 3 lorsqu'il est dans sa première position de fermeture et dans sa deuxième position de fermeture, ces positions se trouvant à environ 180° l'une de l'autre. Des résistances, schématisées en 29, s'étendent dans le conduit 3 en aval du papillon 5 et sont fixées au corps 1. Les résistances 29 laissent passer le fluide et sont en forme d'ailettes en aluminium ou de rubans résistifs fins dont l'épaisseur et les formes sont agencées pour ne pas entraver ou perturber 1 ' écoulement du fluide. Les résistances 29 comportent des moyens, connus en eux-mêmes et non représentés, de liaison à une source d'alimentation en énergie électrique. Les résistances 29 forment un organe de réchauffage de l'air du circuit dérivé 109.The first duct 3 is equipped with a first double flap or butterfly 5 secured to an axis 6 mounted to pivot on the body 1. L! axis 6 comprises an end extending projecting from the body 1 and integral in rotation with a first gear wheel 7, toothed, engaged with an intermediate gear 8 itself engaged with a pinion 9 secured to a shaft of output of a motor 10 mounted on the body 1. The motor 10 is a DC motor known in itself connected to a source of electrical energy and a control module which are also known in themselves and are not shown in the figures. A torsion spring 11 extends helically around said end of the axis 6 having one end connected to the transmission wheel 7 and an end connected to the body 1. The spring 11 recalls the pilion 5 in the open position (shown in Figures 2 to 4). The transmission wheel 7 is provided with lugs 12, 13 which are intended to cooperate with a stop 14 integral with the body 1. When the lug 12 is in abutment against the stop 14, the butterfly 5 is in a first closed position (represented in FIG. 6) and, when the lug 13 bears against the stop 14, the butterfly 5 is in a second closed position (shown in FIG. 7). The butterfly 5 is substantially perpendicular to the duct 3 when in its first closed position and in its second closed position, these positions being at about 180 ° to one another. Resistors, schematized at 29, extend in the conduit 3 downstream of the butterfly 5 and are fixed to the body 1. The resistors 29 pass the fluid and are in the form of aluminum fins or thin resistive ribbons whose The thickness and shapes are arranged so as not to impede or disturb the flow of the fluid. The resistors 29 comprise means, known in themselves and not shown, for connection to a source of power supply. The resistors 29 form an air heating member of the bypass circuit 109.
Le deuxième conduit 4 est équipé d'un deuxième volet double ou papillon 15 solidaire d'un axe 16 qui est monté pour pivoter sur le corps 1 et qui possède une extrémité s ' étendant en saillie du corps 1 et sur laquelle est montée pour pivoter une deuxième roue de transmission 17. Un support est fixé sur cette extrémité de l'axe 16. Le support définit deux bras 18, 19, s ' étendant radiale- ment depuis l'extrémité en saillie de l'axe 6, à l'opposé l'un de l'autre. Chaque bras 18, 19 est pourvu d'un doigt 20, 21 reçu dans une rainure 22, 23, en arc de cercle ménagé dans la roue de transmission 17. Le bras 19 comporte une extrémité libre destinée à venir en butée contre une butée 24 solidaire du corps 1 et définissant la position de fermeture du papillon 15 (représentée sur les figures 2 à 6) . Un ressort de torsion 25 s'étend hélicoïdalement autour de ladite extrémité de l'axe 16 et possède une ex- trémité reliée au doigt 21 et une extrémité opposée reliée au corps 1 pour rappeler le papillon 15 en position de fermeture. En position d'ouverture, le papillon 15 s'étend sensiblement selon l'axe du conduit 4.The second duct 4 is equipped with a second double flap or butterfly 15 integral with an axis 16 which is mounted to pivot on the body 1 and which has an end extending projecting from the body 1 and on which is mounted to rotate a second transmission wheel 17. A support is fixed on this end of the axis 16. The support defines two arms 18, 19, extending radially from the end projecting from the axis 6, to the opposite of each other. Each arm 18, 19 is provided with a finger 20, 21 received in a groove 22, 23, in an arc formed in the transmission wheel 17. The arm 19 has a free end intended to abut against a stop 24 secured to the body 1 and defining the closed position of the butterfly 15 (shown in Figures 2 to 6). A torsion spring 25 extends helically around said end of the shaft 16 and has an end connected to the finger 21 and an opposite end connected to the body 1 to bias the butterfly 15 to the closed position. In the open position, the butterfly 15 extends substantially along the axis of the duct 4.
Les butées 14, 24 sont fixées sur un support ré- glable en position par rapport au corps 1.The abutments 14, 24 are fixed on a support that can be adjusted in position relative to the body 1.
La vanne ainsi réalisée possède :The valve thus produced possesses:
- un mode de fonctionnement normal ou primaire dans lequel le papillon 15 est en position de fermeture et le papillon 5 est réglable en position entre sa posi- tion d'ouverture et sa première position de fermeture (position intermédiaire représentée en figure 5),a normal or primary mode of operation in which the throttle valve 15 is in the closed position and the throttle valve 5 is adjustable in position between its open position and its first closed position (intermediate position shown in FIG. 5),
- un mode d'arrêt dans lequel le papillon 15 est dans sa position de fermeture et le papillon 5 est dans sa première position de fermeture (figure 6), - un mode de fonctionnement secondaire dans lequel le papillon 15 est dans sa position d'ouverture et le papillon 5 est dans sa deuxième position de fermeture (figure 7) .a stopping mode in which the throttle valve 15 is in its closed position and the throttle valve 5 is in its first closed position (FIG. 6), a secondary operating mode in which the throttle valve is in its position of opening and the butterfly 5 is in its second closed position (Figure 7).
En mode de fonctionnement normal, le moteur 10 peut amener le papillon 5 dans n'importe quelle position comprise entre sa position d'ouverture et sa première position de fermeture (voir la position intermédiaire représentée à la figure 5) . Lorsque le papillon 5 est en position d'ouverture (figure 3), les doigts 20, 21 sont reçus dans une extrémité 22.1, 23.1 des rainures 22, 23. Lorsque la roue de transmission 7 pivote entre la position d'ouverture du papillon 5 et sa première position de fermeture, la roue de transmission 7 entraîne la roue de transmission 17 (sens de rotation 40 sur la figure 3) en provoquant le glissement des doigts le long des rainures 22, 23 en direction de l'autre extrémité 22.2, 23.2 de ces rainures. Le papillon 15 est donc immobile, maintenu dans sa position de fermeture par le ressort appliquant l'excroissance du bras 18 contre la butée 24. Lorsque le papillon 5 est dans sa première position de fermeture, les doigts 20, 21 sont reçus dans les extrémités 22.2, 23.2 des rainures 22, 23 et le papillon 15 est dans sa position de fermeture de sorte que la vanne est dans son mode d'arrêt (figure 6) . Lorsque le papillon 5 est ramené vers sa position d'ouverture depuis sa première position de fermeture, la roue de transmission 7 entraîne la roue de transmission 17 et les doigts passent de l'extrémité 22.2, 22.3 des rainures 22, 23 aux extrémités 22.1, 23.1 sans provoquer de mouvement du papillon 15.In normal operating mode, the motor 10 can bring the throttle valve 5 into any position between its open position and its first closed position (see the intermediate position shown in Figure 5). When the butterfly valve 5 is in the open position (FIG. 3), the fingers 20, 21 are received in one end 22.1, 23.1 of the grooves 22, 23. When the transmission wheel 7 pivots between the open position of the butterfly valve 5 and its first closed position, the transmission wheel 7 drives the transmission wheel 17 (direction of rotation 40 in Figure 3) by causing the sliding of the fingers along the grooves 22, 23 towards the other end 22.2, 23.2 of these grooves. The butterfly 15 is thus immobile, held in its closed position by the spring applying the projection of the arm 18 against the stop 24. When the butterfly 5 is in its first closed position, the fingers 20, 21 are received in the ends 22.2, 23.2 grooves 22, 23 and the butterfly 15 is in its closed position so that the valve is in its stop mode (Figure 6). When the throttle valve 5 is brought back to its open position from its first closed position, the transmission wheel 7 drives the transmission wheel 17 and the fingers pass from the end 22.2, 22.3 of the grooves 22, 23 to the ends 22.1, 23.1 without causing movement of the throttle valve 15.
Lorsque la roue de transmission 7 est déplacée pour amener le papillon 5 dans sa deuxième position de fermeture, la roue de transmission 7 provoque une rotation de la roue de transmission 17 dans le sens référencé 30 sur la figure 3. Les doigts 19, 20 étant en butée contre les extrémités 22.1, 23.1 des rainures 22, 23, le pivotement de la roue de transmission 17 va provoquer un pivotement du support et donc de l'axe 16 et du papillon 15. Lorsque le papillon 5 atteint sa deuxième position de fermeture, le papillon 15 est dans sa position d'ouverture. La vanne est dans son mode de fonctionnement secondaire (figure 7) .When the transmission wheel 7 is moved to bring the butterfly valve 5 into its second closed position, the transmission wheel 7 causes a rotation of the transmission wheel 17 in the direction referenced 30 in FIG. 3. The fingers 19, 20 being abutting against the ends 22.1, 23.1 of the grooves 22, 23, the pivoting of the transmission wheel 17 will cause pivoting of the support and therefore of the axis 16 and the throttle valve 15. When the throttle valve 5 reaches its second closed position , the butterfly 15 is in its open position. The valve is in its secondary operating mode (Figure 7).
Lorsque le papillon 5 est ramené de sa deuxième position de fermeture vers sa position d'ouverture (sous l'action également du ressort 11), la roue de transmission 17 est entraînée en sens inverse (sens référencé 40) par la roue de transmission 7 et le ressort 25 exerce sur le doigt 21 un effort de rappel du papillon 15 vers sa position d'obturation. Les doigts 20, 21 et les rainures 22, 23 forment ainsi un organe d'entraînement unidirectionnel (sens 30) du papillon 15, cet organe étant positif (ou actif) lorsque le papillon 5 est entraîné de sa position d'ouverture vers sa deuxième position de fermeture. On notera que les axes 6, 16 des papillons 5, 15 sont implantés au voisinage du troisième conduit 2 et que :When the throttle valve 5 is brought back from its second closed position towards its open position (under the action also of the spring 11), the transmission wheel 17 is driven in the opposite direction (direction referenced 40) by the transmission wheel 7 and the spring 25 exerts on the finger 21 a return force of the butterfly 15 towards its closed position. The fingers 20, 21 and the grooves 22, 23 form and a unidirectional drive member (direction 30) of the butterfly 15, this member being positive (or active) when the butterfly 5 is driven from its open position to its second closed position. It will be noted that the axes 6, 16 of the butterflies 5, 15 are located in the vicinity of the third duct 2 and that:
- en position d'ouverture, les papillons 5, 15 ont une partie s ' étendant en saillie dans le conduit 2, de préférence jusqu'à l'axe du conduit 2, pour guider les gaz et former des déflecteurs ;- In the open position, the butterflies 5, 15 have a portion projecting in the duct 2, preferably to the axis of the duct 2, to guide the gas and form baffles;
- en position de fermeture, les papillons 5, 15 s'étendent au voisinage de la paroi du conduit 2, et de préférence sensiblement en affleurement du conduit 2 et parallèlement à la paroi de celui-ci, pour limiter la formation de zone de recirculation des gaz et autres perturbations du flux de manière à réduire les pertes de charges .- In the closed position, the butterflies 5, 15 extend in the vicinity of the wall of the duct 2, and preferably substantially flush with the duct 2 and parallel to the wall thereof, to limit the formation of recirculation zone gases and other disturbances of the flow so as to reduce the losses of charges.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de 1 ' invention tel que défini par les revendications.Of course, the invention is not limited to the embodiment described and variants can be made without departing from the scope of the invention as defined by the claims.
En particulier, la vanne peut avoir une structure différente de celle décrite, notamment en ce qui concerne l'agencement des conduits, la géométrie des papillons, l'entraînement de la deuxième roue de transmission, les moyens d' actionnement des papillons... Les roues de transmission peuvent être entraînées au moyen de courroies. Le moteur peut être en prise avec la première roue de trans- mission et avec la deuxième roue de transmission, la première roue de transmission ne servant plus alors de lien entre le moteur et la deuxième roue de transmission. Le corps peut être en une ou plusieurs pièces. Au lieu de volet double de type papillon, il est possible d'utiliser des volets simples. L'organe de rappel du deuxième papillon peut être un organe moteur mécanique ou électrique .In particular, the valve may have a different structure from that described, in particular with regard to the arrangement of the conduits, the geometry of the butterflies, the driving of the second transmission wheel, the means for actuating the butterflies, etc. The transmission wheels can be driven by means of belts. The motor can be engaged with the first transmission wheel and with the second transmission wheel, the first transmission wheel then no longer serving as a link between the engine and the second transmission wheel. The body can be in one or more rooms. Instead of double butterfly flap, it is possible to use single flaps. The second throttle return member may be a mechanical or electrical motor member.
L'organe d'entraînement unidirectionnel peut avoir une autre structure que celle décrite et ne compor- ter par exemple qu'un doigt et une rainure. Un doigt peut également être solidaire de la roue de transmission 17 pour prendre appui sur le bras 19.The unidirectional drive member may have a structure other than that described and may comprise, for example, only a finger and a groove. A finger can also be secured to the transmission wheel 17 to bear on the arm 19.
Il va de soi que l'agencement selon lequel au moins un des papillons 5, 15 en position d'ouverture a une partie en saillie dans le troisième conduit 2, et au moins un des papillons 5, 15 en position de fermeture s'étend sensiblement au voisinage, voire en affleurement du troisième conduit 2, est applicable à tout type de vanne ayant trois conduits, par exemple une entrée et deux sorties, avec deux papillons commandés par un ou deux moteurs .It goes without saying that the arrangement in which at least one of the butterflies 5, 15 in the open position has a projecting portion in the third duct 2, and at least one of the butterflies 5, 15 in the closed position extends substantially adjacent or even flush with the third conduit 2, is applicable to any type of valve having three ducts, for example an inlet and two outlets, with two butterflies controlled by one or two motors.
De même, les résistances 29 sont utilisables dans tout type de vanne ayant trois conduits, en particulier une entrée et deux sorties. L'organe de chauffage peut être prévu dans l'un et/ou l'autre des conduits et avoir une structure différente de celle décrite. L'organe de chauffage peut en outre être disposé à un autre endroit du circuit dérivé 109.Similarly, the resistors 29 can be used in any type of valve having three ducts, in particular an inlet and two outlets. The heating member may be provided in one and / or the other of the ducts and have a structure different from that described. The heating element may also be disposed at another location of the bypass circuit 109.
En outre, le sens de rappel des ressorts et la position de rappel des papillons peuvent être différents de ceux décrits ci-dessus.In addition, the return direction of the springs and the return position of the butterflies may be different from those described above.
En variante, on aurait pu envisager un actionne- ment des papillons réalisé au moyen de deux moteurs couples associés chacun à un des papillons . As a variant, it would have been possible to envisage a throttle actuation carried out by means of two paired motors each associated with one of the butterflies.
