Description

L'invention concerne un procédé et un dispositif de positionnement des organes mobiles d'un moteur thermique, dans une position d'arrêt du moteur facilitant le démarrage.The invention relates to a positioning method and device moving parts of a heat engine, in a position where the engine facilitating starting.

Les moteurs thermiques à combustion interne comportent au moins un piston mobile de manière alternative dans un cylindre et généralement plusieurs pistons montés mobiles chacun dans un cylindre, le piston ou chacun des pistons étant relié à un vilebrequin par une bielle entraínant le vilebrequin en rotation autour d'un axe.Internal combustion engines have at least an alternately movable piston in a cylinder and generally several pistons mounted mobile each in a cylinder, the piston or each pistons being connected to a crankshaft by a connecting rod driving the crankshaft rotating around an axis.

On a constaté, qu'après un arrêt d'un moteur thermique, la puissance nécessaire au redémarrage du moteur est essentiellement variable entre une puissance minimale de démarrage et une puissance maximale qui est d'environ 30 % supérieure à la puissance minimale. Bien entendu, afin d'optimiser le fonctionnement des moteurs au démarrage et à solliciter le moins possible le démarreur et la batterie alimentant le démarreur, il serait souhaitable de régler les conditions de fonctionnement du moteur, de manière à pouvoir le démarrer dans tous les cas à une puissance voisine de la puissance minimale.It has been found that after stopping a heat engine, the power necessary to restart the engine is essentially variable between a minimum starting power and a maximum power which is about 30% higher than the minimum power. Of course, in order to optimize engine operation at start-up and to use the least possible the starter and the battery supplying the starter, it would be desirable set the engine operating conditions so that be able to start it in any case at a power close to the power minimal.

L'inventeur de la présente demande de brevet a pu constater que la puissance de démarrage dépendait en particulier de la position des organes mobiles du moteur à l'arrêt avant le démarrage et tout particulièrement de la position angulaire du vilebrequin.The inventor of the present patent application has observed that the starting power depended in particular on the position of the organs the engine stopped before starting and especially the angular position of the crankshaft.

Jusqu'ici, ce fait n'a jamais conduit à la conception d'un procédé permettant de faciliter le démarrage d'un moteur thermique.So far, this fact has never led to the design of a process allowing to facilitate the starting of a heat engine.

L'invention est donc relative à un procédé de positionnement des organes mobiles d'un moteur thermique, dans une position d'arrêt du moteur facilitant le démarrage, le moteur comportant au moins un piston mobile de manière alternative dans un cylindre, relié à un vilebrequin par une bielle entraínant le vilebrequin en rotation autour d'un axe, caractérisé par le fait qu'on règle la position angulaire du vilebrequin autour de son axe de rotation, pour le placer dans une position angulaire prédéterminée, à l'aide d'une machine tournante électrique reliée en rotation au vilebrequin.The invention therefore relates to a method for positioning the organs engines of an internal combustion engine, in an engine stop position facilitating starting, the engine comprising at least one movable piston of alternatively in a cylinder, connected to a crankshaft by a connecting rod driving the crankshaft in rotation about an axis, characterized by the fact that the angular position of the crankshaft is adjusted around its axis of rotation, to place it in a predetermined angular position, using a electric rotating machine connected in rotation to the crankshaft.

Afin de bien faire comprendre l'invention, on va maintenant décrire, à titre d'exemple, en se référant aux figures jointes en annexe, deux modes de réalisation du procédé de positionnement suivant l'invention facilitant le démarrage d'un moteur thermique.In order to clearly understand the invention, we will now describe, at As an example, with reference to the attached figures, two modes of implementation of the positioning method according to the invention facilitating start-up of a heat engine.

La figure 1 est une vue schématique montrant les organes mobiles piston, bielle et vilebrequin d'un moteur thermique et des positions angulaires d'arrêt du vilebrequin.Figure 1 is a schematic view showing the movable members piston, connecting rod and crankshaft of a heat engine and angular positions stop the crankshaft.

La figure 2 est une vue en perspective montrant un dispositif permettant de mettre en oeuvre le procédé de l'invention.Figure 2 is a perspective view showing a device for to implement the method of the invention.

La figure 3 est un logigramme relatif à la mise en oeuvre du procédé suivant l'invention et suivant un premier mode de réalisation.FIG. 3 is a flow diagram relating to the implementation of the method according to the invention and according to a first embodiment.

La figure 4 est une représentation fonctionnelle de moyens pour la mise en oeuvre du procédé suivant l'invention et suivant un second mode de réalisation.Figure 4 is a functional representation of means for the implementation of the method according to the invention and according to a second mode of production.

Sur la figure 1 on a représenté de manière schématique un piston 1 d'un moteur à combustion interne qui se déplace, pendant le fonctionnement du moteur, dans un cylindre du moteur, comme représenté par la double flèche 2.In Figure 1 is shown schematically a piston 1 an internal combustion engine which moves during operation of the engine, in a cylinder of the engine, as represented by the double arrow 2.

Le piston 1 est relié par l'intermédiaire d'une bielle 3 à un vilebrequin 4 monté rotatif autour d'un axe 5.The piston 1 is connected via a connecting rod 3 to a crankshaft 4 rotatably mounted around an axis 5.

Bien entendu, les dimensions relatives des organes du moteur ont été figurées de manière tout à fait conventionnelle. En particulier, la section du vilebrequin 4 a été fortement exagérée pour montrer les positions angulaires d'arrêt du vilebrequin.Of course, the relative dimensions of the engine members have been figured in a completely conventional way. In particular, the section of the crankshaft 4 has been greatly exaggerated to show the angular positions stop the crankshaft.

Le vilebrequin 4 est entraíné en rotation autour de son axe 5 par la bielle 3 transformant le mouvement linéaire du piston 1 en mouvement de rotation.The crankshaft 4 is rotated about its axis 5 by the connecting rod 3 transforming the linear movement of the piston 1 into movement of rotation.

On a constaté que le vilebrequin tel que le vilebrequin 4 d'un moteur thermique, au moment de l'arrêt du moteur, s'arrête systématiquement en une position angulaire autour de son axe de rotation, située dans une zone angulaire s'étendant de part et d'autre d'une position moyenne Pm avec une amplitude angulaire respective A1 et A2.It has been found that the crankshaft such as the crankshaft 4 of a heat engine, when the engine stops, systematically stops in an angular position around its axis of rotation, located in an angular zone extending from on either side of an average position P m with a respective angular amplitude A 1 and A 2 .

Sur la figure 1, on a représenté, sur un cercle en pointillés centré sur l'axe 5 du vilebrequin 4, la position d'arrêt moyenne Pm et les positions extrêmes d'arrêt Pm + A1 et Pm - A2. In Figure 1, there is shown, on a dotted circle centered on the axis 5 of the crankshaft 4, the average stop position P m and the extreme stop positions P m + A 1 and P m - A 2 .

On a également constaté que le démarrage du moteur est réalisé plus facilement à partir de la position initiale moyenne Pm et que le démarrage est d'autant plus difficile que la position initiale du vilebrequin se rapproche des positions extrêmes Pm + A1 et Pm - A2.It has also been found that the engine is started more easily from the mean initial position P m and that the start is all the more difficult as the initial position of the crankshaft approaches the extreme positions P m + A 1 and P m - A 2 .

Lors d'un démarrage à partir d'un des deux points extrêmes Pm + A1 et Pm - A2, la puissance de démarrage nécessaire est d'environ 30 % supérieure à la puissance correspondant à la position initiale moyenne Pm.When starting from one of the two extreme points P m + A 1 and P m - A 2 , the starting power required is approximately 30% higher than the power corresponding to the average initial position P m .

En partant de cette constatation, l'inventeur de la présente demande de brevet a conçu un procédé et un dispositif permettant de faciliter le démarrage d'un moteur thermique et de réaliser, dans tous les cas, le démarrage du moteur, dans des conditions pratiquement optimales.On the basis of this observation, the inventor of the present application patent has designed a process and a device to facilitate start-up of a heat engine and to carry out, in all cases, starting of the engine, in practically optimal conditions.

L'invention concerne donc un procédé et un dispositif permettant de placer les organes mobiles du moteur et en particulier le vilebrequin, de manière automatique, dans une position facilitant le démarrage du moteur et permettant un démarrage avec une puissance de démarrage minimale.The invention therefore relates to a method and a device for place the moving parts of the engine and in particular the crankshaft so that automatic, in a position facilitating the starting of the engine and allowing starting with minimal starting power.

Sur la figure 2, on a représenté de manière schématique un dispositif permettant de mettre en oeuvre le procédé de l'invention, pour faciliter le démarrage d'un moteur thermique 6 représenté, de manière conventionnelle, sous la forme d'un parallélépipède.In Figure 2, there is shown schematically a device making it possible to implement the method of the invention, to facilitate the starting a heat engine 6 shown, in a conventional manner, in the form of a parallelepiped.

Le moteur thermique 6 comporte un vilebrequin monté rotatif suivant un axe longitudinal du moteur 6 et solidaire, à ses extrémités longitudinales, d'une poulie 7 et d'un volant 8, respectivement.The heat engine 6 comprises a crankshaft mounted to rotate as follows a longitudinal axis of the motor 6 and integral with its longitudinal ends, a pulley 7 and a flywheel 8, respectively.

Le dispositif de réglage de la position d'arrêt du moteur selon l'invention comporte une machine électrique tournante 10 qui peut être, comme il sera expliqué plus loin, un alternateur ou un moteur électrique.The device for adjusting the engine stop position according to the invention comprises a rotary electric machine 10 which can be, as it will be explained later, an alternator or an electric motor.

Sur l'arbre de sortie rotatif 11 de la machine tournante 10 est calée une poulie 12. Une courroie d'entraínement 13 passant sur les poulies 7 et 12 permet de réaliser une liaison en rotation du vilebrequin du moteur thermique 6 et de l'arbre de sortie de la machine tournante 10. Bien entendu, la liaison en rotation du-vilebrequin du moteur 6 et de l'arbre de la machine tournante 10 pourrait être obtenue par des moyens différents de poulies et d'une courroie. On the rotary output shaft 11 of the rotary machine 10 is fixed a pulley 12. A drive belt 13 passing over the pulleys 7 and 12 allows a rotational connection of the crankshaft of the heat engine 6 and the output shaft of the rotary machine 10. Of course, the rotation connection of the crankshaft of the engine 6 and of the machine shaft rotating 10 could be obtained by different means of pulleys and a strap.

La machine tournante électrique 10 est reliée, par l'intermédiaire d'un module de commande électronique 9, à une batterie 14 qui peut être la batterie d'un véhicule automobile entraíné par le moteur thermique 6.The electric rotary machine 10 is connected, via a electronic control module 9, to a battery 14 which may be the battery of a motor vehicle driven by the heat engine 6.

Un capteur de position 15 permet de repérer de manière très précise la position angulaire du volant 8 et du vilebrequin du moteur 6. Le capteur de position 15 est relié au module de commande électronique 9, de manière à transmettre un signal de position représentatif de la position instantanée du vilebrequin du moteur thermique 6. Le module de commande électronique 9 reçoit également un signal de consigne 16 correspondant à un signal de position représentatif de la position moyenne idéale Pm du vilebrequin du moteur thermique 6, pour laquelle le démarrage est obtenu avec une puissance de démarrage minimale.A position sensor 15 makes it possible to very precisely locate the angular position of the flywheel 8 and of the crankshaft of the engine 6. The position sensor 15 is connected to the electronic control module 9, so as to transmit a position signal representative of the instantaneous position of the engine crankshaft 6. The electronic control module 9 also receives a reference signal 16 corresponding to a position signal representative of the ideal average position P m of the engine engine crankshaft 6, for which starting is obtained with minimum starting power.

Selon un premier mode de réalisation de l'invention, on réalise le réglage de position angulaire du vilebrequin du moteur, pendant l'arrêt du moteur, pour obtenir une position de redémarrage favorable du moteur après l'arrêt.According to a first embodiment of the invention, the adjustment is carried out angular position of the engine crankshaft, while the engine, to obtain a favorable restart position of the engine after the stop.

Au moment où l'arrêt du moteur est demandé par le conducteur (fonction stop), un ordre est transmis au boítier électronique de commande 9, de manière qu'il réalise l'acquisition d'un signal de position angulaire du vilebrequin du moteur thermique 6 transmis par le capteur de position 15. Le boítier de commande électronique 9 réalise l'acquisition en continu de la position angulaire instantanée du vilebrequin du moteur thermique 6. On peut réaliser également l'acquisition de la vitesse de rotation du vilebrequin, en temps réel, pendant la décélération du moteur,When the engine is requested to stop the engine (stop function), an order is transmitted to the electronic control unit 9, so that it acquires an angular position signal from the crankshaft of the heat engine 6 transmitted by the position sensor 15. The electronic control unit 9 continuously acquires the position instantaneous angular angle of the crankshaft of the heat engine 6. We can also carry out the acquisition of the crankshaft rotation speed, real time, during engine deceleration,

La machine électrique tournante 10, qui peut être constituée par l'alternateur du véhicule automobile, est réalisée et commandée de manière à pouvoir fonctionner de façon réversible.The rotary electrical machine 10, which can be constituted by the alternator of the motor vehicle, is produced and controlled so as to be able to operate reversibly.

Pendant l'arrêt et la décélération du moteur thermique, la machine électrique réversible 10 permet de piloter la décélération du moteur pour forcer son arrêt sur la position angulaire privilégiée Pm du vilebrequin du moteur thermique 6. La machine électrique est pilotée par le boítier de commande électronique 9, de façon à créer un couple résistant permettant de freiner le moteur thermique 6. Le courant produit par la machine électrique réversible 10 permet alors de recharger la batterie 14.During the stopping and deceleration of the heat engine, the reversible electric machine 10 makes it possible to control the deceleration of the engine to force it to stop on the preferred angular position P m of the crankshaft of the heat engine 6. The electric machine is controlled by the housing of electronic control 9, so as to create a resisting torque making it possible to brake the heat engine 6. The current produced by the reversible electric machine 10 then makes it possible to recharge the battery 14.

La commande de la machine électrique 10 est adaptée pour tenir compte, à tous les régimes de fonctionnement du moteur thermique, de la valeur du couple produit, de manière à assurer une approche correcte de la position d'arrêt idéale du vilebrequin.The control of the electric machine 10 is adapted to hold account, at all operating speeds of the heat engine, of the value of the torque produced, so as to ensure a correct approach to the ideal stop position of the crankshaft.

Sur la figure 3, on a représenté, sous la forme d'un logigramme, la mise en oeuvre du procédé suivant l'invention et suivant le premier mode de réalisation.In Figure 3, there is shown, in the form of a flowchart, the implementation of the method according to the invention and according to the first mode of production.

L'unité de commande électronique de la machine électrique constituée par exemple par un alternateur de type réversible reçoit en entrée un signal de position du vilebrequin du moteur mot. Le signal de position est traité dans une première unité 17 du module de commande, de manière à obtenir la vitesse du moteur exprimée en tour/minute sous la forme de la valeur N et comparé, comme représenté en 18a, 18b et 18c sur la figure 3, à la vitesse du moteur au ralenti Nr et à une vitesse N1 prédéterminée inférieure à la vitesse au ralenti Nr.The electronic control unit of the electric machine constituted for example by a reversible type alternator receives as input a position signal from the crankshaft of the engine mot. The position signal is processed in a first unit 17 of the control module, so as to obtain the motor speed expressed in revolutions / minute in the form of the value N and compared, as shown in 18a, 18b and 18c in the figure 3, at the engine speed at idle N r and at a predetermined speed N 1 lower than the idle speed N r .

Lorsque la vitesse instantanée du moteur N est comprise entre N1 et Nr, on commande l'alternateur par le boítier électronique 9, de manière à réaliser un freinage continu du moteur thermique 6. Cette étape du procédé est représentée en19a.When the instantaneous speed of the engine N is between N 1 and N r , the alternator is controlled by the electronic unit 9, so as to achieve continuous braking of the heat engine 6. This step of the process is shown in 19a.

Lorsque la vitesse du moteur N est inférieure à la vitesse N1, avant l'arrêt du moteur thermique, on réalise un freinage périodique du moteur thermique 6 par l'alternateur, comme représenté en 19b. Le freinage périodique consiste à freiner le moteur thermique 6, lorsque le vilebrequin se trouve entre les deux positions extrêmes Pm + A1 et Pm - A2, c'est-à-dire dans la zone angulaire d'arrêt du vilebrequin. On module le couple résistant exercé sur le moteur thermique à partir de l'alternateur 10, de manière à augmenter le couple résistant à l'approche de la position idéale Pm du vilebrequin.When the speed of the engine N is lower than the speed N 1 , before the thermal engine stops, a periodic braking of the thermal engine 6 is carried out by the alternator, as shown in 19b. Periodic braking consists in braking the heat engine 6, when the crankshaft is between the two extreme positions P m + A 1 and P m - A 2 , that is to say in the angular stop zone of the crankshaft. The resistive torque exerted on the heat engine is modulated from the alternator 10, so as to increase the resistive torque when approaching the ideal position P m of the crankshaft.

Lorsqu'on a obtenu l'arrêt complet du moteur, comme représenté en 18c, on réalise une comparaison entre la position du vilebrequin mesurée par le capteur de position 15 et la position théorique idéale Pm. Si l'on détecte un écart entre ces deux positions, on réalise un recalage statique comme figuré à l'étape 19c sur la figure 3. Le recalage statique du vilebrequin consiste à alimenter l'alternateur fonctionnant en moteur, pour le faire tourner dans un sens ou dans l'autre jusqu'à obtenir la position idéale du vilebrequin.When the engine has been stopped completely, as shown in 18c, a comparison is made between the position of the crankshaft measured by the position sensor 15 and the ideal theoretical position P m . If a difference between these two positions is detected, a static registration is carried out as shown in step 19c in FIG. 3. Static registration of the crankshaft consists in supplying the alternator operating with the engine, to rotate it in a in either direction until the ideal position of the crankshaft is obtained.

L'alternateur peut alors être utilisé en moteur pour réaliser le démarrage du moteur thermique avec une puissance de démarrage réduite.The alternator can then be used as an engine to start the engine. of the engine with reduced starting power.

La fonction de l'alternateur réversible réalisant, au moment de l'arrêt du moteur, son positionnement dans la position angulaire idéale et le démarrage du moteur à partir de cette position idéale peut faciliter la mise en oeuvre d'une fonction "stop and start".The function of the reversible alternator realizing, at the time of stopping the motor, positioning it in the ideal angular position and starting motor from this ideal position can facilitate implementation a "stop and start" function.

Le procédé suivant l'invention peut être mis en oeuvre selon un second mode de réalisation dans lequel on procède au recalage du moteur thermique 6 après son arrêt complet, pour placer le vilebrequin dans sa position angulaire idéale.The method according to the invention can be implemented according to a second embodiment in which the engine is reset thermal 6 after its complete stop, to place the crankshaft in its position ideal angular.

Les éléments de calcul et de commande mis en oeuvre dans ce mode de réalisation ont été représentés de manière schématique sur la figure 4.The calculation and control elements used in this mode are shown schematically in FIG. 4.

L'alternateur réversible 10 est relié à la batterie 14 d'alimentation, qui peut être la batterie d'un véhicule automobile, par l'intermédiaire du boítier électronique de commande 9.The reversible alternator 10 is connected to the supply battery 14, which can be the battery of a motor vehicle, through the housing control electronics 9.

Un capteur de position angulaire est associé à l'arbre de sortie 11 de l'alternateur réversible 10 et fournit un signal alt représentatif de la position angulaire de l'arbre de l'alternateur à un séquenceur de position 20.An angular position sensor is associated with the output shaft 11 of the reversible alternator 10 and provides a signal alt representative of the position angle of the alternator shaft to a position sequencer 20.

Le dispositif de calcul et de commande comporte un bloc de calcul 21 qui reçoit en entrée le signal de position angulaire mot provenant du capteur de position angulaire du vilebrequin et qui prend en compte une valeur mise en mémoire représentative de la position idéale Pm du vilebrequin. Le bloc de calcul 21 élabore trois signaux de commande représentés par les flèches 22a, 22b et 22c qui sont transmises au séquenceur de position 20.The calculation and control device comprises a calculation block 21 which receives as input the angular position signal mot from the angular position sensor of the crankshaft and which takes into account a value stored in memory representative of the ideal position P m of the crankshaft. The calculation block 21 generates three control signals represented by the arrows 22a, 22b and 22c which are transmitted to the position sequencer 20.

Les signaux 22a, 22b et 22c définissent le déplacement nécessaire au recalage du moteur thermique en utilisant l'alternateur réversible 10 dans sa fonction moteur. Signals 22a, 22b and 22c define the necessary displacement to the registration of the heat engine using the reversible alternator 10 in its motor function.

Le signal 22a est représentatif du sens de rotation du déplacement nécessaire au recalage, le signal 22b est représentatif de l'angle du déplacement nécessaire au recalage et le signal 22c est représentatif du couple à exercer sur le vilebrequin du moteur pour obtenir le recalage.The signal 22a is representative of the direction of rotation of the movement necessary for registration, signal 22b is representative of the angle of displacement necessary for registration and the signal 22c is representative of the torque at exercise on the engine crankshaft to obtain registration.

Le séquenceur de position 20 permet de commander l'alternateur réversible 10, par l'intermédiaire d'un boítier électronique 23 reliant l'alternateur 10 à la batterie 14 et assurant la conversion courant continu/courant alternatif.The position sequencer 20 makes it possible to control the reversible alternator 10, via an electronic box 23 connecting the alternator 10 to battery 14 and ensuring direct current / current conversion alternative.

Le couple nécessaire au recalage, qui est généré par alimentation de l'alternateur 10, par l'intermédiaire du boítier électronique, est modulé en amplitude, de manière à placer rapidement et précisément le vilebrequin du moteur dans sa position angulaire idéale Pm.The torque necessary for registration, which is generated by supplying the alternator 10, via the electronic unit, is amplitude-modulated, so as to quickly and precisely place the crankshaft of the engine in its ideal angular position P m .

Le procédé suivant l'invention permet donc de placer ou de replacer rapidement les éléments mobiles du moteur au moment de l'arrêt ou après l'arrêt du moteur thermique, pour obtenir des conditions de démarrage idéales, lors d'une utilisation future du moteur.The process according to the invention therefore makes it possible to place or replace quickly the moving parts of the engine when stopping or after stopping the engine, to obtain ideal starting conditions, during future use of the engine.

Dans le cas où l'on réalise la mise en oeuvre du procéde de l'invention en utilisant un alternateur réversible qui peut être l'alternateur du véhicule automobile dont le moteur thermique assure la traction, les moyens supplémentaires nécessaires pour cette mise en oeuvre sont constitués uniquement par un capteur de mesure de position angulaire du vilebrequin et par une unité de calcul et de commande programmée. La mise en oeuvre du procédé de l'invention n'entraíne donc qu'un très faible surcoût dans le cadre de la production industrielle d'un véhicule automobile.In the case where the implementation of the method of the invention is carried out using a reversible alternator which can be the vehicle alternator automobile with internal combustion engine providing traction, additional resources necessary for this implementation consist only by a sensor for measuring the angular position of the crankshaft and by a programmed calculation and control unit. The implementation of process of the invention therefore involves only a very low additional cost in the context of the industrial production of a motor vehicle.

Il est toutefois possible d'utiliser un moteur électrique indépendant de l'alternateur pour réaliser le recalage du moteur thermique, ou un système mécanique débrayable.It is however possible to use an electric motor independent of the alternator to realign the thermal engine, or a system disengageable mechanical.

La mise en oeuvre du procédé de l'invention selon le premier mode de réalisation permet d'autre part d'obtenir une économie d'énergie, du fait qu'on récupère de l'énergie-de charge de la batterie, pendant le freinage du moteur thermique, lors de son arrêt. En outre, l'obtention de la position idéale d'arrêt du moteur est obtenue plus rapidement que lorsqu'on effectue un recalage consécutif à l'arrêt du moteur: Cependant, la mise en oeuvre du procédé de l'invention selon le premier mode de réalisation est relativement complexe et nécessite l'utilisation de moyens de calcul et de commande d'une assez grande complexité.The implementation of the method of the invention according to the first mode of realization allows on the other hand to obtain an energy saving, because that we recover energy-charge from the battery, during braking of the engine, when stopped. In addition, obtaining the position ideal engine shutdown is achieved faster than when performing a readjustment consecutive to the stopping of the engine: However, the implementation of the method of the invention according to the first embodiment is relatively complex and requires the use of calculation and control means quite complex.

La mise en oeuvre du procédé de l'invention par le second mode de réalisation est moins complexe. Cependant, cette mise en oeuvre est plus lente et nécessite l'utilisation de l'énergie électrique des batteries du véhicule.The implementation of the method of the invention by the second mode of realization is less complex. However, this implementation is more slow and requires the use of electrical energy from vehicle batteries.

L'invention ne se limite pas aux modes de réalisation qui ont été décrits.The invention is not limited to the embodiments which have been described.

C'est ainsi qu'on peut utiliser à la place d'un alternateur réversible, un ensemble constitué par un alternateur et un moteur.It is thus that one can use instead of a reversible alternator, a set consisting of an alternator and a motor.

On peut utiliser une machine électrique de tout type à alimentation continue ou alternativeWe can use an electric machine of any type with supply continuous or alternative

L'invention s'applique à tout moteur thermique et en particulier aux moteurs thermiques assurant la traction des véhicules automobiles.The invention applies to any heat engine and in particular to thermal engines providing traction for motor vehicles.
