Abstract

Description

La présente invention vise à perfectionner les turbo-compresseurs pour moteurs à combustion interne et elle se rapporte en particulier à des dispositifs capables de leur assurer un régime de rotation élevés
I1 est connu que, dans le domaine des moteurs à combustion interne à cycle Otto, pour améliorer les performances, on fait fréquemment appel à des dispositifs de suralimentation intéressant le mélange ou l'air aspiré. Parmi les dispositifs qui sont actuellement les plus fréquemment utilisés pour obtenir cette suralimentation, on compte les turbo-compresseurs, machines composees de l'accouple- ment d'une turbine centripète actionnée par les gaz d'échappement du moteur et d'un compresseur centrifuge.A côte des nombreux avantages apportés par ce dispositif de suralimentation, il existe malheureusement des inconvénients et l'un des plus graves de ces incon vénients réside dans le "trou" de puissance que lton perçoit dans le moteur pendant quelques instants lorsqu'on demande de la puise sance immédiatement après une décélération.The present invention aims to improve turbo-compressors for internal combustion engines and it relates in particular to devices capable of providing them with a high rotation speed.
It is known that, in the field of internal combustion engines with an Otto cycle, to improve performance, frequent use is made of supercharging devices involving the mixture or the air drawn. Among the devices which are currently the most frequently used to obtain this supercharging, there are turbo-compressors, machines composed of the coupling of a centripetal turbine actuated by the exhaust gases of the engine and a centrifugal compressor. .Besides the many advantages brought by this supercharging device, there are unfortunately disadvantages and one of the most serious of these inconveniences is the "hole" of power that lton perceives in the engine for a few moments when you ask of the source immediately after deceleration.

Cet inconvénient résulte du fait que, pendant la phase de décélération, le débit des gaz d'échappement du moteur est notablement réduit par la raréfaction des gaz dans le conduit d'admission; la tubulure montée sur le conduit déchappement n'est donc pas alimentée de façon suffisante, de sorte que le turbo-compresseur subit une réduction notable de sa vitesse de rotation. This drawback results from the fact that, during the deceleration phase, the flow rate of the exhaust gases from the engine is notably reduced by the scarcity of gases in the intake duct; the tubing mounted on the exhaust pipe is therefore not supplied with sufficient power, so that the turbo-compressor undergoes a significant reduction in its rotation speed.

Lorsque le conducteur de la voiture demande à nouveau de la puissance au moteur, en agissant sur l'accélérateur, le turbo- compresseur reçoit le nouveau débit de gaz d'échappement mais, en raison de ses inerties et de ses frottements, il demande quelques instants pour revenir à son régime de fonctionnement normal. Par conséquent, pendant ces quelques instants, il ne comprime pas le mélange et le moteur fonctionne alors comme s'il n'était pas suralimenté, en donnant une désagréable impression de "trou de puissance". When the driver of the car again requests power from the engine, by acting on the accelerator, the turbo-compressor receives the new exhaust gas flow rate but, due to its inertia and friction, it requires some moments to return to its normal operating regime. Consequently, during these few moments, it does not compress the mixture and the engine then operates as if it were not supercharged, giving an unpleasant impression of "power hole".

Dès que le turbo-compresseur a atteint son régime, il. assure sa fonction en faisant développer au moteur toute sa puissance et, dans certaines circonstances (par exemple, en virage, sur route mouillée, etc), il peut même être dangereux pour la stabilité de la voiture. Le but de l'invention est de remédier aux inconvénients précités, en réalisant un turbo-compresseur pour moteur à combustion interne, alimenté par les gaz d'échappement du moteur-et qui, suivant sa caractéristique fondamentale, est équipé d'un dispositif auxiliaire destiné à le maintenir à un régime de rotation élevé, même dans la phase de débit réduit des gaz d'échappement. As soon as the turbo-compressor has reached its speed, it. ensures its function by making the engine develop all its power and, in certain circumstances (for example, in turns, on wet roads, etc.), it can even be dangerous for the stability of the car. The object of the invention is to remedy the aforementioned drawbacks, by producing a turbo-compressor for an internal combustion engine, powered by the engine exhaust gases and which, according to its fundamental characteristic, is equipped with an auxiliary device. intended to maintain it at a high rotational speed, even in the phase of reduced exhaust gas flow.

En général, cette phase de débit réduit se manifeste, par exemple, pendant le fonctionnement du moteur au ralenti mais, grâce au dispositif suivant l'invention, dans la phase consécutive d'accélération, le turbo-compresseur peut développer aussitôt sa pleine puissance. In general, this phase of reduced flow manifests itself, for example, during the operation of the engine at idle but, thanks to the device according to the invention, in the consecutive phase of acceleration, the turbo-compressor can immediately develop its full power.

Ce dispositif peut être constitué par un moteur quelconque de type actuellement connu, calé sur l'arbre du compresseur, qui n'assure sa fonction que lorsque la vitesse de rotation du turhocompresseur tend à décroitre et on peut entendre par moteur un moteur électrique, une turbine hydraulique alimentée par l'huile du moteur ou par un circuit hydraulique collatéral, une turbine à gaz, une turbine à air comprimé ou équivalent. This device can be constituted by any engine of the currently known type, wedged on the compressor shaft, which only performs its function when the speed of rotation of the turbocharger tends to decrease and we can hear by motor an electric motor, a hydraulic turbine powered by engine oil or by a collateral hydraulic circuit, a gas turbine, a compressed air turbine or equivalent.

D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre de deux exemples de réalisation et en se référant aux dessins annexés sur lesquels,
la figure 1 est une coupe longitudinale d'un turbo-compresseur pour moteur à combustion interne qui comprend le dispositif objet de l'invention ; et
la figure 2 représente une variante.Other characteristics and advantages of the invention will be better understood on reading the following description of two exemplary embodiments and with reference to the appended drawings in which,
Figure 1 is a longitudinal section of a turbo-compressor for an internal combustion engine which comprises the device object of the invention; and
Figure 2 shows a variant.

On se reportera tout d'abord à la figure 1 sur laquelle on a indiqué en 16 le rotor de la turbine1 qui est mis en rotation par les gaz d'échappement du moteur à combustion interne, gaz qui sont acheminés par le conduit tangentiel en volute 18 et déchargés par un conduit axial 20. L'énergie cédée par ces gaz au rotor 16 est transmise par l'intermédiaire de llgrbre 8 à la partie compresseur de l'appareil, dans laquelle le rotor 10 élève la pression des gaz aspirés par le moteur Sous cet effet, ces gaz, qui arrivent du conduit 12 à une pression proche de la pression atmosphérique, sont envoyés au moteur par le conduit tangentiel 14 à la pression de sur alimentation voulue. We will firstly refer to FIG. 1 in which the rotor of the turbine 1 which is rotated by the exhaust gases of the internal combustion engine, which is conveyed by the tangential volute duct, has been indicated at 16. 18 and discharged through an axial duct 20. The energy transferred by these gases to the rotor 16 is transmitted via the valve 8 to the compressor part of the apparatus, in which the rotor 10 raises the pressure of the gases sucked in by the engine Under this effect, these gases, which arrive from the duct 12 at a pressure close to atmospheric pressure, are sent to the engine by the tangential duct 14 at the desired over-supply pressure.

Dans une première forme de réalisation, la particularité de l'invention consiste dans le fait que l'arbre 8 est prolongé par l'arbre 22 qui relie ltensemble compresseur-turbine à un moteur auxiliaire de type connu qui, dans la forme de réalisation de la figure 1, est un moteur électrique 24. Ce moteur fournit au compresseur l'énergie qui lui est nécessaire pour se maintenir à un régime de rotation élevé, même lorsque l'apport énergétique des gaz d'échappement au rotor 16 est réduit ou presque annulé parce que le noteur à cmmbustion interne se trouve en phase de décélération. In a first embodiment, the characteristic of the invention consists in the fact that the shaft 8 is extended by the shaft 22 which connects the compressor-turbine assembly to an auxiliary motor of known type which, in the embodiment of Figure 1 is an electric motor 24. This motor provides the compressor with the energy it needs to maintain a high rotation speed, even when the energy supply of the exhaust gases to the rotor 16 is reduced or almost canceled because the internal cmmbustion grader is in the deceleration phase.

Suivant une autre forme de réalisation, représentée sur la figure 2, l'invention est mise en oeuvre dans un dispositif qui, en étranglant judicieusement la section du conduit d'échappement du moteur pendant la phase de décélération, confère aux gaz d échappement, bien que ces derniers soient à un débit réduit, une quantité de mouvement suffisante pour maintenir l'ensemble à un régime de rotation élevé. According to another embodiment, represented in FIG. 2, the invention is implemented in a device which, by judiciously throttling the cross section of the engine exhaust duct during the deceleration phase, gives the exhaust gases well that the latter are at a reduced flow rate, a sufficient amount of movement to maintain the assembly at a high rotation speed.

Sur la figure 2, on a représenté une coupe transversale de la turbine d'un groupe turbo-compresseur mettant en oeuvre cette deuxième forme de réalisation de l'invention. Dans les conditions normales de fonctionnement, les gaz d'échappement arrivent par le conduit en volute 30 relié à l'échappement du moteur et actionnent le rotor de la turbine 36 en l'attaquant tangentiellement. In Figure 2, there is shown a cross section of the turbine of a turbo-compressor unit implementing this second embodiment of the invention. Under normal operating conditions, the exhaust gases arrive via the volute duct 30 connected to the engine exhaust and actuate the rotor of the turbine 36 by tangentially attacking it.

La particularité de cette forme de réalisation de l'invention consiste dans la présence d'un obturateur papillon 32 qui, pendant la phase de décélération, est tourné de manière à obturer le conduit principal 30. On reste dans le domaine de l'invention en utilisant n'importe quelle autre forme d'obturateur ( à ogive, à pointeau, à champignon etc.) qui, intercalé dans l'arrivée de la turbine, exerce la même fonction. The particularity of this embodiment of the invention consists in the presence of a butterfly shutter 32 which, during the deceleration phase, is rotated so as to close the main duct 30. We remain in the field of the invention in using any other form of obturator (with a warhead, a needle, a mushroom, etc.) which, inserted in the inlet of the turbine, performs the same function.

Sous cet effet, pendant la phase de décélération, le débit réduit des gaz d'échappement est contraint de s'écouler par le conduit 26 de section réduite, placé en dérivation par rapport à l'obturateur 32, ce conduit comportant des orifices c librés 38 appropriés pour conférer aux gaz la vitesse voulue et présentant son aju tage de sortie convenablement dirigé vers le rotir. De cette façon, les gaz d'échappement qui arrivent du conduit 26 à une vitesse élevée attaquent convenablement le rotor 36 et maintiennent le groupe turbo-compresseur à un régime de rotation élevé. Under this effect, during the deceleration phase, the reduced flow of exhaust gases is forced to flow through the conduit 26 of reduced section, placed in bypass with respect to the shutter 32, this conduit having openings c freed 38 suitable for imparting the desired speed to the gases and having its outlet nozzle suitably directed towards the roast. In this way, the exhaust gases which arrive from the duct 26 at a high speed suitably attack the rotor 36 and maintain the turbo-compressor unit at a high rotation speed.

Bien entendu, diverses modifications pourront être appor- tées par l'homme de l'art aux dispositifs qui viennent d'être décrit à titre d'exemple non limitatif sans pour cela sortir du cadre de l'invention. Of course, various modifications may be made by those skilled in the art to the devices which have just been described by way of non-limiting example without thereby departing from the scope of the invention.
