Abstract

A pollution control method and related devices for cyclical internal combustion engines having a separate combustion chamber (1), wherein the compression chamber, the combustion chamber (1) and the expansion chamber (16) consist of three separate and entirely self-contained portions. During low-power operation, e.g. in urban traffic, the fuel injector (6) is no longer controlled during filling of the combustion chamber, whereby the combustion chamber is filled with high-temperature pure compressed air at each cycle. A small amount of additional air from an outer tank (23) for storing highly pressurised air at room temperature is fed into the combustion chamber substantially after the intake of compressed air from the engine compressor, and heated as it contacts the hot compressed air already present in the combustion chamber (1), whereafter it expands and increases the starting pressure to enable effective work to be produced during expansion.

Description

PROCEDE ET DISPOSITIFS DE DEPOLLUTION DE MOTEURS A COMBUSTION INTERNE CYCLIQUE A CHAMBRE DE COMBUSTION INDEPENDANTEPROCESS AND DEVICES FOR DEPOLLUTION OF CYCLIC INTERNAL COMBUSTION ENGINES WITH INDEPENDENT COMBUSTION CHAMBER
L'invention concerne un procédé et des dispositifs de dépollution des moteurs à combustion interne cyclique à chambre de combustion indépendante et à volume constant.The invention relates to a method and devices for depolluting cyclic internal combustion engines with an independent combustion chamber and at constant volume.
L'auteur a décrit dans ses demandes de brevets Français ayant pour numéros d'enregistrement national 9501518 et 9502212 un procédé de moteur à combustion interne cyclique à chambre de combustion indépendante et à volume constant, dans lequel la chambre de compression, la chambre de combustion et la chambre de détente sont constituées de trois parties séparées et entièrement indépendantes permettant ainsi d'adapter chacun des trois éléments à la fonction qui lui est dévolue sans interférer les uns sur les autres; ainsi qu'un système de contrôle de la détente (9502212) qui permet de faire coïncider la pression maximum de détente avec un angle de rotation du vilebrequin permettant un grand effort tangentiel, améliorant encore le rendement général de ce type de moteur. Toutefois, lors du fonctionnement en zone urbaine notamment sur des voitures, le moteur consomme encore du carburant de telle sorte que bien que diminuées dans des proportions très importante il subsiste encore des émissions de polluants.The author has described in his French patent applications having national registration numbers 9501518 and 9502212 a process of cyclic internal combustion engine with independent combustion chamber and constant volume, in which the compression chamber, the combustion chamber and the expansion chamber are made up of three separate and entirely independent parts, thus making it possible to adapt each of the three elements to the function assigned to it without interfering with one another; as well as a rebound control system (9502212) which makes it possible to make the maximum rebound pressure coincide with a rotation angle of the crankshaft allowing a great tangential force, further improving the general efficiency of this type of engine. However, during operation in urban areas, especially on cars, the engine still consumes fuel so that, although reduced in very large proportions, there are still emissions of pollutants.
Le procédé suivant l'invention permet de supprimer complètement ces émissions de gaz polluants notamment en circulation urbaine, alors que le moteur demande peu de puissance. II est caractérisé par les moyens mis en oeuvre, et plus particulièrement par le fait que lors des fonctionnements sous faible puissance, l'injecteur de carburant n'est plus commandé et que dans ce cas, l'on introduit dans la chambre de combustion, par tout moyen approprié - sensiblement après l'admission dans cette dernière de l'air comprimé (sans carburant) provenant du compresseur du moteur - une petite quantité d'air additionnel provenant d'un réservoir externe dans lequel est stocké de l'air (ou tout autre gaz) sous très haute pression; cette petite quantité d'air comprimé, et à température ambiante, va s'échauffer au contact de la masse d'air chaud contenue dans la chambre de combustion, se dilater et augmenter de façon sensible la pression régnant dans la chambre de combustion, pour permettre de délivrer lors de la détente, un travail moteur de puissance suffisante pour faire fonctionner, par exemple, un véhicule en circulation urbaine. Le réglage de la quantité d'air additionnel injecté conditionnera la puissance délivrée.The method according to the invention makes it possible to completely eliminate these polluting gas emissions, especially in urban traffic, while the engine requires little power. It is characterized by the means used, and more particularly by the fact that during operations under low power, the fuel injector is no longer controlled and that, in this case, it is introduced into the combustion chamber, by any appropriate means - substantially after the admission into the latter of compressed air (without fuel) coming from the engine compressor - a small amount of additional air coming from an external tank in which air is stored ( or any other gas) under very high pressure; this small amount of compressed air, and at room temperature, will heat up in contact with the mass of hot air contained in the combustion chamber, expand and significantly increase the pressure prevailing in the combustion chamber, to allow to deliver during the relaxation, a motor work of sufficient power to operate, for example, a vehicle in urban traffic. The adjustment of the quantity of additional air injected will condition the power delivered.
Il est également caractérisé par le fait d'équiper le moteur d'un compresseur haute pression, qui sera embrayé lors des ralentissements ou lors du fonctionnement à puissance élevée, pour permettre de recharger en air comprimé à très haute pression le réservoir externe permettant ainsi d'améliorer l'autonomie en fonctionnement dépollué On comprend des lors le fonctionnement du moteur suivant l'invention qui pourra ainsi fonctionner sous de faibles puissances, en zone urbaine, sans émission de gaz polluants, et instantanément, à la demande, pourra produire des puissances compatibles avec une utilisation normale sur route, dès lors que l'injection de carburant sera commandée et que l'injecteur d'air additionnel ne le sera plusIt is also characterized by the fact of equipping the motor with a high pressure compressor, which will be engaged during slowdowns or during operation at high power, to allow the external tank to be recharged with compressed air at very high pressure, thus allowing '' improve autonomy in depolluted operation We therefore understand the operation of the engine according to the invention which will thus be able to operate at low powers, in urban areas, without emission of polluting gases, and instantly, on demand, will be able to produce powers compatible with normal use on the road, as soon as the fuel injection is ordered and the additional air injector is no longer ordered
La quantité d'air additionnel injecté, les moyens d'injection, le mode de stockage de l'air compπmé, le gaz utilisé, les moyens de remplissage du réservoir de stockage - par compresseur embarqué fonctionnant lors des décélérations et freinages ou en fonctionnement route, et/ou a la pompe dans des stations services spécialement équipées ou, encore, par remplacement de la bouteille de stockage - peuvent varier sans pour autant changer le principe de l'inventionThe quantity of additional air injected, the injection means, the storage mode of the compressed air, the gas used, the means for filling the storage tank - by on-board compressor operating during decelerations and braking or in road operation , and / or at the pump in specially equipped service stations or, alternatively, by replacing the storage bottle - may vary without changing the principle of the invention
L'invention s'applique tout particulièrement aux moteurs a combustion interne cyclique a chambre de combustion indépendante a volume constant, notamment en utilisation urbaine sur véhicule, ainsi que pour toute autre application de moteur Elle s'applique également aux moteurs a combustion interne conventionnels D'autres buts, avantages et caractéristiques de l'invention apparaîtront a la lecture de ia description, a titre non limitatif, de plusieurs modes de réalisation, faite en regard des dessins annexés oùThe invention applies very particularly to cyclic internal combustion engines with independent combustion chamber at constant volume, in particular in urban use on a vehicle, as well as for any other engine application. It also applies to conventional internal combustion engines D other objects, advantages and characteristics of the invention will appear on reading the description, without implied limitation, of several embodiments, made with reference to the appended drawings where
- La figure 1 représente, vu en coupe transversale, un mode de réalisation de l'invention appliquée a un moteur a combustion interne a chambre de combustion indépendante a volume constant au point mort haut de piston principal en fin d'échappement- Figure 1 shows, seen in cross section, an embodiment of the invention applied to an internal combustion engine with independent combustion chamber at constant volume at the top dead center of the main piston at the end of exhaust
- La figure 2 représente ce même moteur en début de détente- Figure 2 shows the same engine at the start of expansion
- La figure 3 représente un schéma synoptique d'installation sur véhicule- Figure 3 shows a block diagram of installation on vehicle
Les figures 1 et 2 représentent un mode de réalisation du procède selon l'invention appliqué a un moteur à combustion interne cyclique à chambre de combustion indépendante a volume constant où la chambre de combustion 1 est alimentée par une capacité tampon 2 d'air comprime maintenu a une pression sensiblement constante, elle même alimentée par un compresseur a travers un conduit 3 Un conduit 4 dont l'ouverture et la fermeture sont commandées par un volet 5 relie la capacité tampon 2 a la chambre de combustion indépendante 1 et comporte un injecteur de carburant 6 destiné a réaliser le mélange air-carburant sensiblement avant son introduction dans la chambre de combustion 1 où il sera enflammeFigures 1 and 2 show an embodiment of the method according to the invention applied to a cyclic internal combustion engine with independent combustion chamber at constant volume where the combustion chamber 1 is supplied by a buffer capacity 2 of compressed air maintained at a substantially constant pressure, itself supplied by a compressor through a conduit 3 A conduit 4, the opening and closing of which are controlled by a flap 5 connects the buffer capacity 2 to the independent combustion chamber 1 and comprises an injector for fuel 6 intended to produce the air-fuel mixture substantially before its introduction into the combustion chamber 1 where it will be ignited
Un cylindre de détente 7 est équipé d'un piston principal 8 relie par une bielle 9 au maneton d'un vilebrequin 10, et d'un piston opposé secondaire 11 dont le mouvement est commande ici par une came 12 - elle-même entraînée par le vilebrequin 10 - de telle sorte qu'il va accompagner le piston principal 8 sur une partie de sa course descendante afin de permettre de faire coïncider la pression de début de détente - dès l'ouverture du canal 14, par le volet 15, qui relie la chambre de combustion à la chambre de détente 16 - dans un volume minimum, avec des angles de rotation du vilebrequin et d'inclinaison de bielle qui permettent d'obtenir l'effort tangentiel moyen de détente optimal.A detent cylinder 7 is equipped with a main piston 8 connected by a connecting rod 9 to the crankpin of a crankshaft 10, and a secondary opposite piston 11 whose movement is controlled here by a cam 12 - itself driven by the crankshaft 10 - so that it will accompany the main piston 8 over part of its downward stroke in order to allow the pressure at the start of expansion to coincide - as soon as the channel 14 opens, by the flap 15, which connects the room combustion in the expansion chamber 16 - in a minimum volume, with angles of rotation of the crankshaft and inclination of the connecting rod which make it possible to obtain the average tangential stress of optimal relaxation.
Un injecteur d'air comprimé additionnel 22, suivant l'invention, est implanté dans la chambre de combustion 1, et est alimenté, à travers un détendeur, par une bouteille d'air compπmé 23 (ou de tout autre gaz compatible) de stockage sous haute pression.An additional compressed air injector 22, according to the invention, is located in the combustion chamber 1, and is supplied, through a pressure reducer, by a bottle of compressed air 23 (or any other compatible gas) for storage under high pressure.
En fonctionnement sous faible puissance, selon l'invention, lorsque le moteur est au point mort haut du cylindre de détente, figure 1 , la chambre de combustion 1 vient d'être isolée et contient une masse d'air comprimé chaud, pur, sans carburant - l'injecteur de carburant 6 n'ayant pas été commandé - L'injecteur d'air additionnel 22 est ouvert et introduit dans la chambre une petite quantité de masse d'air additionnel, provenant de la bouteille de stockage sous haute pression 23, détendue sous une pression légèrement supérieure à celle régnant dans la chambre de combustion, pour permettre le transfert; cette masse d'air additionnel va s'échauffer au contact de l'air comprimé contenu dans la chambre, se dilater et augmenter sensiblement la pression initiale afin de permettre de produire un travail lors de l'ouverture , figure 2, du canal 14 en se détendant dans la chambre de détente. En raison de l'excellent rendement du groupe moteur représenté, la quantité d'air additionnel sera très faible et conditionnera la puissance délivrée.In operation under low power, according to the invention, when the engine is in top dead center of the expansion cylinder, FIG. 1, the combustion chamber 1 has just been isolated and contains a mass of hot, pure compressed air, without fuel - the fuel injector 6 not having been ordered - The additional air injector 22 is open and introduces into the chamber a small amount of additional air mass, coming from the high pressure storage bottle 23 , expanded under a pressure slightly higher than that prevailing in the combustion chamber, to allow transfer; this additional air mass will heat up in contact with the compressed air contained in the chamber, expand and substantially increase the initial pressure in order to allow work to be produced when the channel 14 is opened, FIG. 2 relaxing in the relaxation room. Due to the excellent performance of the engine group shown, the amount of additional air will be very small and will condition the power delivered.
Les moyens d'injection d'air additionnel dans la chambre de combustion peuvent varier sans changer le principe de l'invention, toutefois l'on préférera un injecteur électromécanique tel que les injecteurs de carburant qui pourra être géré plus aisément, notamment en débit, par l'électronique embarquée.The means for injecting additional air into the combustion chamber can vary without changing the principle of the invention, however an electromechanical injector such as the fuel injectors will be preferred which can be managed more easily, in particular in flow rate, by on-board electronics.
La figure 3 représente un schéma synoptique d'une installation du procédé suivant l'invention sur un véhicule, où le réservoir de stockage d'air comprimé additionnel sous haute pression 23A est équipé d'une part d'un orifice de remplissage "à la pompe" 24 et également d'un orifice de remplissage auxiliaire 25 alimenté par un petit compresseur haute pression embarqué 26 qui sera mis en fonctionnement par un système d'embrayage 27 lors des décélérations et des freinages, permettant ainsi de fournir un excellent frein moteur au véhicule, et également lors du fonctionnement sur route à puissance élevée. Cette disposition ayant pour avantage d'augmenter considérablement l'autonomie en fonctionnement dépollué. II va sans dire que la conception du réservoir, de l'injecteur d'air, du compresseur haute pression, de son embrayage, des vannes de remplissage et autres clapets anti-retour, peuvent varier sans pour autant changer le principe de l'invention qui n'est nullement limitée aux modes de réalisations décrits et représentés, et est susceptible de nombreuses variantes accessibles à l'homme de l'art, suivant les applications envisagées, sans que l'on ne s'écarte de son esprit. FIG. 3 represents a block diagram of an installation of the method according to the invention on a vehicle, where the additional compressed air storage tank 23A is equipped on the one hand with a filling orifice "at the pump "24 and also an auxiliary filling orifice 25 supplied by a small on-board high pressure compressor 26 which will be put into operation by a clutch system 27 during deceleration and braking, thus making it possible to provide an excellent engine brake to the vehicle, and also when operating on high power roads. This arrangement having the advantage of considerably increasing the autonomy in clean-up operation. It goes without saying that the design of the reservoir, the air injector, the high pressure compressor, its clutch, filling valves and other non-return valves, can vary without changing the principle of the invention which is by no means limited to the embodiments described and shown, and is capable of numerous variants accessible to those skilled in the art, depending on the applications envisaged, without departing from its spirit.
