Description

1 La présente invention concerne un procédé et un système de mise en veille d'un moteur à combustion, notamment monté sur un véhicule, sans l'arrêt de sa rotation, en vue de sa proche remise en fonctionnement normal. Le moteur ne sera ainsi utilisé que lorsqu'il est en charge. Cette invention permet aussi d'éliminer le démarreur électrique devenu inutile, et d'adopter ainsi une batterie électrique sans fort débit maxi. Un moteur à combustion de type automobile fournit un travail lorsqu'il est chargé, mais continue à fonctionner quand on ne lui demande pas de couple moteur, par exemple en descente, à l'arrêt au feu rouge. Il continue alors à consommer du carburant, à émettre des gaz polluants, du bruit, des vibrations, de la chaleur, à s'user, en pure perte. Cet inconvénient est très préjudiciable notamment en ville et en circulation dense ou bloquée, où le moteur n'est que très peu utilisé. Certains systèmes dits « stop and start » pour arrêt démarrage apportent une solution à ce problème, mais seulement pour des arrêts bien définis. Ces arrêts doivent être supérieurs à 3 secondes et imposent que le véhicule soit immobile. Ils imposent aussi le redémarrage du moteur par un système démarreur à grosse consommation électrique. Cette invention de procédé et système de mise en veille permet de remédier à ce problème de moteur inutilisé continuant à fonctionner. L'invention consiste à mettre le moteur en veille tout en conservant sa rotation. Pour cela, son alimentation en carburant est coupée. Il fonctionne alors sans aucune émission de gaz polluants, sans aucune consommation de carburant, sans bruit, et sans vibrations. Sa rotation sera mise en mode libre par élimination de ses compressions. La partie mobile du moteur se trouve ainsi dégagée de toute contrainte. Le vilebrequin (6) tourne et les pistons (1) translatent librement sans aucun effort. L'invention permet au moteur de repartir sans redémarrage, simplement par restauration des compressions et de l'alimentation en carburant. Grace à l'invention, le démarrage sera instantané, sans à-coups, et sans intervention extérieure de démarreur consommant de l'électricité. Grace à l'invention, les systèmes annexes au moteur et entraînés par celui-ci, tels que hydraulique de direction, lubrification interne, refroidissement à eau, climatisation.... ne sont pas interrompus puisque le moteur continue sa rotation en mode veille, à la différence d'un système « stop and start ». Cette invention permet d'activer le mode mise en veille aussi souvent que désiré, c'est-à-dire dès que le moteur n'est plus travaillant. Une gestion électronique de cette mise en veille permet de couper le moteur même avec le véhicule en mouvement, dès l'annulation du couple moteur sur l'arbre de sortie par exemple. Exemple du véhicule 3038006 2 dans une descente : le moteur est mis en veille avec consommation zéro. Le « frein moteur » peut être conservé en gardant une partie de compression mais sans carburant. Le moteur peut aussi passer en mode veille dès que l'embrayage est actionné puisque le couple moteur n'est pas utilisé. Exemple entre les changements de 5 rapports de boite a vitesse Un système « E-clutch » pour Embrayage Electronique, déjà existant, aidera cette fonction. De mini mises en veille sont possibles. Exemple : Durant 1 seconde. Grace à cette invention, la consommation de carburant, l'émission de gaz polluants, le bruit, les vibrations, l'usure sont éliminés en mode veille. L'économie de carburant peut 10 être très importante. La réalisation technique de cette invention concerne les moteurs classiques de type cycle à 4 temps à carburant essence ou diésel, de type mono ou multi cylindres. La coupure et la remise en fonction de l'alimentation en carburant se fait par une gestion simple, électrique et électronique, de l'injection de carburant existante. La suppression des 15 compressions se fait par l'ouverture continue des chambres de combustion durant tout le temps de mise en veille. Cette fonction se fait par ouverture d'un orifice dans les chambres de combustion du moteur. Cet orifice est soit la soupape d'admission (2) maintenue ouverte comme décrit sur la figure 1, soit la soupape d'échappement (3) maintenue ouverte comme décrit sur la figure 2, soit les deux soupapes (2) et (3) maintenues ouvertes 20 comme décrit sur la figure 3, soit une communication (5) ouverte entre les cylindres comme décrit sur la figure 4. La plus simple et efficace des solutions est l'ouverture de soupapes à commande électrique (4), éliminant toute distribution sur le moteur comme sur figure 5. Une gestion simple, électrique et électronique suffit alors à mettre en place l'invention. La tête de soupape ne doit pas interférer avec la trajectoire du piston.The present invention relates to a method and a system of standby of a combustion engine, in particular mounted on a vehicle, without stopping its rotation, with a view to its near return to normal operation. The motor will only be used when it is charging. This invention also eliminates the electric starter become useless, and thus adopt an electric battery without high maximum flow. A combustion engine of automobile type provides a job when loaded, but continues to operate when it is not asked engine torque, for example downhill, stopped on a red light. It then continues to consume fuel, to emit polluting gases, noise, vibrations, heat, to wear, a pure waste. This disadvantage is very detrimental especially in the city and in heavy traffic or blocked, where the engine is very little used. Some so-called stop and start systems provide a solution to this problem, but only for well-defined stops. These stops must be greater than 3 seconds and require the vehicle to be stationary. They also require the restart of the engine by a starter system with large power consumption. This process invention and standby system makes it possible to remedy this problem of unused motor which continues to operate. The invention consists in putting the motor in standby while maintaining its rotation. For this, its fuel supply is cut off. It then operates without any emission of polluting gases, without any fuel consumption, without noise, and without vibrations. Its rotation will be put in free mode by elimination of its compressions. The moving part of the engine is thus free from any constraint. The crankshaft (6) rotates and the pistons (1) move freely without any effort. The invention allows the engine to restart without restarting, simply by restoring compressions and fuel supply. Thanks to the invention, the start-up will be instantaneous, without jerks, and without external intervention starter consuming electricity. Thanks to the invention, the systems attached to the engine and driven by it, such as hydraulic steering, internal lubrication, water cooling, air conditioning .... are not interrupted since the engine continues its rotation in standby mode, unlike a "stop and start" system. This invention enables the sleep mode as often as desired, that is to say as soon as the engine is no longer working. An electronic management of this standby allows to cut the engine even with the moving vehicle, as soon as the engine torque on the output shaft is canceled for example. Example of the vehicle 3038006 2 in a descent: the engine is put to sleep with zero consumption. The "engine brake" can be kept while keeping a compression part but without fuel. The engine can also go into standby mode as soon as the clutch is actuated since the engine torque is not used. Example between changes in 5 speed gear ratios An already existing "E-clutch" system for Electronic Clutch will help this function. Mini standby is possible. Example: During 1 second. Thanks to this invention, the fuel consumption, the emission of gaseous pollutants, the noise, the vibrations, the wear are eliminated in standby mode. Fuel economy can be very important. The technical embodiment of this invention relates to conventional cycle type 4-stroke gasoline or diesel fuel, single or multi-cylinder type. The shutdown and restart of the fuel supply is done by a simple management, electrical and electronic, of the fuel injection existing. The suppression of the 15 compressions is done by the continuous opening of the combustion chambers during all the time of standby. This function is done by opening an orifice in the combustion chambers of the engine. This orifice is either the inlet valve (2) kept open as described in FIG. 1, or the exhaust valve (3) kept open as described in FIG. 2, or the two valves (2) and (3). kept open as described in FIG. 3, ie a communication (5) open between the cylinders as described in FIG. 4. The simplest and most efficient solution is the opening of electrically controlled valves (4), eliminating any distribution. on the engine as in Figure 5. Simple management, electrical and electronic enough to implement the invention. The valve head must not interfere with the piston path.

25 La rotation du moteur en mode veille doit être légèrement assistée pour rester continue, surtout en raison de l'entrainement des accessoires. Cette assistance est assurée par un petit moteur électrique ou par l'alternateur électrique déjà en place sur la voiture. Cet alternateur devient alors un alternateur moteur. Sa consommation électrique est négligeable en comparaison à celle du démarreur électrique classique.The rotation of the engine in standby mode should be slightly assisted to remain continuous, especially because of the training of the accessories. This assistance is provided by a small electric motor or by the electric alternator already in place on the car. This alternator then becomes a motor alternator. Its power consumption is negligible compared to that of the conventional electric starter.

30 La rotation en mode veille peut être diminuée. Exemple 600 Rotations par Minutes. Cette invention de procédé et système de mise en veille permet, grâce à cette fonction assurée par le petit moteur, de supprimer le démarreur électrique classique, devenu inutile. Le démarrage à froid de type parking se fait alors suivant l'ordre suivant : Arrêt mise en veille moteur - activation des compressions et alimentation carburant. Cette 35 application de l'invention est une conséquence de ses avantages.The rotation in standby mode can be decreased. Example 600 Rotations per Minutes. This process invention and standby system allows, thanks to this function provided by the small engine, to remove the conventional electric starter, become unnecessary. The cold start of the parking type is then done in the following order: Engine standby stop - activation of compressions and fuel supply. This application of the invention is a consequence of its advantages.

3038006 3 La suppression du démarreur entraine la simplification de la batterie électrique n'ayant plus besoin de délivrer une forte puissance électrique.

L'obturation de ces communications en fonctionnement normal n'est pas représentée. La figure 5 représente en coupe le schéma d'un moteur à piston (1) classique équipé de soupapes à commande électriques (4).3038006 3 The suppression of the starter leads to the simplification of the electric battery no longer needing to deliver a high electrical power. This other application of the invention is a second consequence of its advantages.
