Description

La présente invention concerne un procédé de régulation de la température de la surface interne des chemises de cylindres d'un moteur à combustion interne refroidi par circulation d'un fluide réfrigérant, de manière à éviter l'usure corrosive de cette surface quelles que soient les conditions d'utilisation du moteur.The present invention relates to a method for regulating the temperature of the internal surface of the liners of cylinders of an internal combustion engine cooled by the circulation of a coolant, so as to avoid corrosive wear of this surface whatever the engine operating conditions.

Elle concerne également un dispositif de mise en oeuvre de ce procédé.It also relates to a device for implementing this method.

Les combustibles dérivés du pétrole les plus dégradés, et utilisés dans certains moteurs Diesel, ont l'inconvénient de renfermer une proportion importante de composés soufrés. L'eau générée par la combustion favorise sous certaines conditions de température et de pression la formation d'acide sulfurique. Cette acide corrode la paroi des chemises, abrégeant leur durée de vie.The most degraded petroleum fuels, used in certain diesel engines, have the disadvantage of containing a large proportion of sulfur compounds. The water generated by combustion favors the formation of sulfuric acid under certain temperature and pressure conditions. This acid corrodes the lining of the shirts, shortening their lifespan.

L'expérimentation montre que pour une température pariétale de 150°C l'usure corrosive reste faible ou nulle. Par contre, à 130°C, les effets conjugués de l'acide et de la température conduisent à une agressivité maximale.Experimentation shows that for a wall temperature of 150 ° C the corrosive wear remains low or zero. On the other hand, at 130 ° C, the combined effects of acid and temperature lead to maximum aggressiveness.

Les moteurs Diesel modernes ont, dans la zone de la chemise la plus exposée, une température pariétale supérieure à 150°C lorsque le moteur est au voisinage de la pleine charge. Mais si le moteur est employé à charge partielle (25% par exemple), le flux thermique à travers la paroi de la chemise est divisé par trois, et comme le flux de réfrigération du moteur est maintenu à température constante par le dispositif de régulation conventionnel, il s'ensuit une chute importante de la température pariétale de chemise et il y a risque de corrosion sulfurique.Modern diesel engines have, in the most exposed area of the jacket, a wall temperature above 150 ° C when the engine is near full load. But if the engine is used at partial load (25% for example), the heat flow through the wall of the jacket is divided by three, and as the engine cooling flow is maintained at constant temperature by the conventional regulating device , there follows a significant drop in the lining wall temperature and there is a risk of sulfuric corrosion.

Pour lutter contre ce phénomène, on utilise des huiles de graissage basiques qui ont pour effet de neutraliser l'acide. Lorsque le piston est au point mort haut, la partie de la chemise située sous les segments râcleurs est lubrifiée par une huile constamment renouvelée. Au contraire, la zone située entre le segment coup de feu et le ou les segments râcleurs n'est alimentée que par l'huile consommée par le moteur, ceci ne représentant que 1/200 de la consommation de carburant environ. Cette dernière zone est donc particulièrement exposée lorsque la température de la chemise atteint une valeur critique, le renouvellement trop faible de l'huile n'assurant pas un pouvoir neutralisant suffisant.To combat this phenomenon, basic lubricating oils are used which have the effect of neutralizing the acid. When the piston is in top dead center, the part of the jacket located under the scraper segments is lubricated by a constantly renewed oil. On the contrary, the zone located between the gunshot segment and the scraper segment (s) is supplied only by the oil consumed by the engine, this representing only 1/200 of the fuel consumption. about. This latter zone is therefore particularly exposed when the temperature of the jacket reaches a critical value, the too low renewal of the oil not ensuring sufficient neutralizing power.

La présente invention a pour objet de résoudre les inconvénients énumérés ci-dessus tout en réduisant au minimum les paramètres de régulation et leur traitement.The object of the present invention is to solve the drawbacks listed above while minimizing the regulation parameters and their processing.

L'invention a pour objet un procédé de régulation de la température de la surface interne des chemises de cylindres d'un moteur à combustion interne refroidi par circulation d'un fluide réfrigérant, caractérisé en ce que l'on régule la température du fluide réfrigérant pour maintenir la température de la surface interne des chemises égale à une température de consigne quelle que soit la charge du moteur.The subject of the invention is a method for regulating the temperature of the internal surface of the liners of cylinders of an internal combustion engine cooled by the circulation of a coolant, characterized in that the temperature of the coolant is regulated to maintain the temperature of the inner surface of the liners equal to a set temperature regardless of the engine load.

Avantageusement, on choisit la température de consigne de telle sorte que la température de la surface interne des chemises se situe en dehors de la zone de température pour laquelle la corrosion par l'acide sulfurique existe compte tenu des conditions d'utilisation du moteur.Advantageously, the set temperature is chosen so that the temperature of the inner surface of the liners is outside the temperature zone for which corrosion by sulfuric acid exists taking into account the conditions of use of the engine.

En particulier, on choisit la température de consigne de telle sorte que la température de la surface interne des chemises soit toujours supérieure à la zone de température où la corrosion par l'acide sulfurique existe.In particular, the set temperature is chosen so that the temperature of the internal surface of the liners is always higher than the temperature zone where corrosion by sulfuric acid exists.

L'invention a également pour objet un dispositif de régulation de la température de la surface interne des chemises de cylindres d'un moteur à combustion interne, comprenant une circulation d'un fluide réfrigérant à travers des conduits situés dans la paroi des chemises, des moyens de réglage de la température du fluide réfrigérant, un ou plusieurs capteurs de température logés dans la paroi des chemises de cylindres et associés aux moyens de réglage par l'intermédiaire d'une commande, caractérisé en ce que la partie sensible du ou des capteurs de température est située dans l'épaisseur de la paroi des chemises comprise entre la surface interne des chemises et les conduits.The invention also relates to a device for regulating the temperature of the internal surface of the liners of cylinders of an internal combustion engine, comprising a circulation of a coolant fluid through conduits located in the wall of the liners, means for adjusting the temperature of the coolant, one or more temperature sensors housed in the wall of the cylinder liners and associated with the adjustment means by means of a control, characterized in that the sensitive part of the sensor (s) temperature is located in the thickness of the wall of the liners between the inner surface of the liners and the conduits.

Il est décrit ci-après, à titre d'exemple et en référence aux dessins annexés, un dispositif conforme à l'invention.

  • La figure 1 représente en coupe une chemise d'un cylindre.
  • La figure 2 représente schématiquement un dispositif de circulation du fluide réfrigérant.
There is described below, by way of example and with reference to the accompanying drawings, a device according to the invention.
  • Figure 1 shows in section a jacket of a cylinder.
  • Figure 2 schematically shows a circu device lation of the refrigerant.

Dans la figure 1, une chemise 1, possédant une surface interne 1' entourée de conduits de circulation 10 d'un fluide réfrigérant, est fermée par une culasse 8 partiellement représentée. Un piston 2, muni d'une jupe 9, est représenté à son point mort haut.In FIG. 1, a jacket 1, having an internal surface 1 'surrounded by conduits for circulation of a refrigerant, is closed by a cylinder head 8 partially shown. A piston 2, provided with a skirt 9, is shown at its top dead center.

Le piston 2 comporte côté culasse un segment coup de feu 3, et côté jupe deux segments compresseurs 4 et deux segments râcleurs 4A, 4B. La zone Z1 représente la partie annulaire de la surface 1' qui est en regard de l'espace séparant le dessus du segment coup de feu du dessous du dernier segment râcleur 4B lorsque le piston est au point mort haut.The piston 2 comprises on the breech side a shot segment 3, and on the skirt side two compressor segments 4 and two scraper segments 4A, 4B. Zone Z 1 represents the annular part of the surface 1 ′ which is opposite the space separating the top of the gun segment from below the last scraper segment 4 B when the piston is in top dead center.

Un capteur de température 6 est logé dans la paroi de la chemise 1, la partie active 7 de ce capteur étant située en regard de la zone Z et dans l'épaisseur comprise entre la surface interne 1' et les conduits de refroidissement 10. Ce capteur 6 mesure, en regard de la zone Z1, la température de la surface 1'. On peut bien entendu, installer plusieurs capteurs. Cette zone Z1 ne reçoit que le débit d'huile qui franchit le barrage des segments râcleurs, ce qui est insuffisant pour compenser l'attaque de l'acide à basse température.A temperature sensor 6 is housed in the wall of the jacket 1, the active part 7 of this sensor being located opposite zone Z and in the thickness between the internal surface 1 'and the cooling conduits 10. This sensor 6 measures, opposite zone Z 1 , the temperature of surface 1 '. It is of course possible to install several sensors. This zone Z 1 receives only the oil flow which crosses the barrier of the scraper segments, which is insufficient to compensate for the attack of the acid at low temperature.

La zone Z2 représente la partie annulaire de la surface 1' située côté jupe sous le dernier des segments râcleurs 4B.Zone Z 2 represents the annular part of the surface 1 ′ located on the skirt side under the last of the scraping segments 4B.

Cette zone Z2 reçoit une quantité importante d'huile basique de graissage.This zone Z 2 receives a large quantity of basic lubricating oil.

La figure 2 montre schématiquement les éléments principaux d'un dispositif de régulation permettant la mise en oeuvre du procédé. La chemise 1 est refroidie par une circulation 11 d'un fluide réfrigérant traversant les conduits 10 représentés en figure 1. Ce circuit comprend une pompe 12 et des moyens de réglage 13, 14, 15 de la température du fluide réfrigérant. Ces moyens de réglage sont une vanne 13 actionnée par un moteur 13', un échangeur de chaleur 14 et un conduit 15, la vanne 13 permettant de dériver tout ou partie du fluide réfrigérant dans le conduit 15. Le moteur 13' actionne cette vanne sous l'action d'une commande 16 reliée au moteur par une liaison électrique, pneumatique ou hydraulique 19. Cette commande 16 agit en fonction de l'écart du paramètre de température du capteur 6 avec une température de consigne 18 par la liaison 17. La température de consigne 18 peut être ajustée en fonction de l'utilisation du moteur, en particulier en fonction de la qualité du combustible utilisé et de sa teneur en composés soufrés.Figure 2 shows schematically the main elements of a regulation device allowing the implementation of the method. The jacket 1 is cooled by a circulation 11 of a coolant passing through the conduits 10 shown in FIG. 1. This circuit includes a pump 12 and means 13, 14, 15 for adjusting the temperature of the coolant. These adjustment means are a valve 13 actuated by a motor 13 ′, a heat exchanger 14 and a conduit 15, the valve 13 making it possible to divert all or part of the refrigerant fluid in the conduit 15. The motor 13 ′ actuates this valve under the action of a control 16 connected to the engine by an electrical, pneumatic or hydraulic connection 19. This control 16 acts as a function of the difference in the temperature parameter of the sensor 6 with a set temperature 18 by the connection 17. The setpoint temperature 18 can be adjusted by depending on the use of the engine, in particular depending on the quality of the fuel used and its content of sulfur compounds.

Une opération de régulation s'effectue de la manière suivante : Lorsque le moteur est à pleine charge ou au voisinage de la pleine charge, le flux thermique est maximum dans la zone Z1. Cette zone est maintenue à une température de 150°C par exemple par les moyens de réglage de la température du fluide réfrigérant. L'action de l'acide sulfurique est alors maintenue à son niveau le plus basA regulation operation is carried out as follows: When the engine is at full load or in the vicinity of full load, the heat flux is maximum in zone Z 1 . This zone is maintained at a temperature of 150 ° C., for example by the means for adjusting the temperature of the coolant. The action of sulfuric acid is then kept at its lowest level

Si la charge du moteur diminue, le flux thermique dans la zone Z diminue et dans le cas où la température du fluide réfrigérant circulant . dans les conduits 10 est maintenue constante, il y a baisse de température de la zone Z1 et celle-ci est alors soumise à l'action de l'acide sulfurique.If the engine load decreases, the heat flow in zone Z decreases and in the case where the temperature of the circulating refrigerant. in the conduits 10 is kept constant, there is a temperature drop in the zone Z 1 and this is then subjected to the action of sulfuric acid.

Conformément à l'invention, la baisse de température mesurée par le capteur 6 engendre une réaction de la commande 16, provoquant une diminution du débit du fluide réfrigérant dans l'échangeur de chaleur 14 grâce à la vanne 13 qui dérive alors une partie du fluide dans le conduit 15. La température du fluide réfrigérant augmente, donc la quantité de chaleur évacuée de la zone Z1 par les conduits 10 diminue en conséquence. Ceci a donc pour effet de maintenir la température de la zone dangereuse à une valeur suffisante pour conserver une action minimale de l'acide sulfurique.According to the invention, the drop in temperature measured by the sensor 6 generates a reaction of the control 16, causing a decrease in the flow rate of the refrigerant fluid in the heat exchanger 14 thanks to the valve 13 which then drifts part of the fluid in the duct 15. The temperature of the refrigerant increases, therefore the quantity of heat evacuated from the zone Z 1 by the ducts 10 decreases accordingly. This therefore has the effect of maintaining the temperature of the danger zone at a value sufficient to maintain a minimal action of sulfuric acid.
