On a en effet représenté sur cette figure 1, un moteur Diesel de véhi cule automobile qui est désigné par la référence générale 1. FIG. 1 shows a motor vehicle diesel engine which is designated by the general reference 1.
Ce moteur Diesel est associé à des moyens d'admission d'air en en trée de celui-ci, qui sont désignés par la référence générale 2. This diesel engine is associated with air intake means at the inlet thereof, which are designated by the general reference 2.
En sortie, ce moteur est associé à une ligne d'échappement qui est , désignée par la référence générale 3. At the output, this engine is associated with an exhaust line which is, designated by the general reference 3.
Des moyens de recyclage de gaz d'échappement du moteur en entrée de celui-ci sont également prévus et sont désignés par la référence générale 4.

La ligne d'échappement peut également être associée à un turbocom presseur désigné par la référence générale 5 et plus particulièrement à la portion de turbine de celui-ci, de façon classique. The exhaust line can also be associated with a pressurized turbocharger designated by the general reference 5 and more particularly with the turbine portion thereof, in a conventional manner.
Enfin, la ligne d'échappement comporte un catalyseur d'oxydation dé signé par la référence générale 6, disposé en amont d'un filtre à particules dési gné par la référence générale 7, dans la ligne d `échappement. Finally, the exhaust line includes an oxidation catalyst designated by the general reference 6, disposed upstream of a particulate filter designated by the general reference 7, in the exhaust line.
Le moteur est également associé à un système d'alimentation com mune en carburant des cylindres de celui-ci. Ce système est désigné par la réfé- rence générale 8 sur cette figure et comporte par exemple des injecteurs à com mande électrique associés à ces cylindres. The engine is also associated with a common fuel supply system for the cylinders thereof. This system is designated by the general reference 8 in this figure and comprises, for example, electrically controlled injectors associated with these cylinders.
Dans l'exemple de réalisation représenté, le moteur est un moteur à quatre cylindres et comporte donc quatre injecteurs à commande électrique, res pectivement 9,10,11 et 12. In the embodiment shown, the engine is a four-cylinder engine and therefore comprises four electrically controlled injectors, respectively 9, 10, 11 and 12.
Ces différents injecteurs sont associés à une rampe d'alimentation commune en carburant désignée par la référence générale 13 et reliée à des moyens d'alimentation en carburant désignés par la référence générale 14, com prenant par exemple une pompe à haute pression. These different injectors are associated with a common fuel supply rail designated by the general reference 13 and connected to fuel supply means designated by the general reference 14, including for example a high pressure pump.
Ces moyens d'alimentation sont reliés à un réservoir de carburant dé signé par la référence générale 15 et à des moyens d'ajout à ce carburant d'un additif destiné à se déposer sur le filtre à particules pour abaisser la température de combustion des particules piégées dans celui-ci. These supply means are connected to a fuel tank designated by the general reference 15 and to means for adding to this fuel an additive intended to be deposited on the particle filter to lower the combustion temperature of the particles. trapped in it.
En fait, cet additif peut par exemple être contenu dans un réservoir auxiliaire désigné par la référence générale 16 associé au réservoir de carburant 15, pour permettre l'injection d'une certaine quantité de cet additif dans le carbu rant. In fact, this additive can for example be contained in an auxiliary tank designated by the general reference 16 associated with the fuel tank 15, to allow the injection of a certain quantity of this additive into the fuel.
Enfin, ce moteur et les différents organes qui viennent d'être décrits sont également associés à des moyens de contrôle de leur fonctionnement dési gnés par la référence générale 17 sur cette figure, comprenant par exemple tout calculateur approprié 18 associé à des moyens de stockage d'informations 19, et raccordé en entrée à différents moyens d'acquisition d'informations relatives à différents paramètres de fonctionnement de ce moteur et de ces organes, ce cal culateur étant alors adapté pour contrôler le fonctionnement des moyens d'admission, des moyens de recyclage, du turbocompresseur et/ou du système d'alimentation pour piloter le fonctionnement du moteur et notamment le couple engendré par celui-ci en fonction des conditions de roulage du véhicule de façon classique. Finally, this engine and the various members which have just been described are also associated with means for controlling their operation designated by the general reference 17 in this figure, comprising for example any suitable computer 18 associated with storage means for 'information 19, and connected as input to different means for acquiring information relating to different operating parameters of this engine and of these members, this calculator then being adapted to control the operation of the intake means, recycling, of the turbocharger and / or of the fuel system to control the operation of the engine and in particular the torque generated by it as a function of the driving conditions of the vehicle in a conventional manner.
C'est ainsi par exemple que ce calculateur est relié à un capteur de pression différentielle 20 aux bornes du catalyseur et du filtre à particules, res pectivement 6 et 7, à des capteurs de température 21,22 et 23, respectivement en amont du catalyseur, entre ce catalyseur et le filtre à particules et en aval de ce filtre à particules dans la ligne d'échappement. Le calculateur peut également recevoir une information de teneur en oxygène des gaz d'échappement à partir d'une sonde Lambda a, désignée par la référence générale 24 sur cette figure, intégrée dans la ligne d'échappement. Thus, for example, this computer is connected to a differential pressure sensor 20 at the terminals of the catalyst and of the particle filter, respectively 6 and 7, to temperature sensors 21, 22 and 23, respectively upstream of the catalyst. , between this catalyst and the particulate filter and downstream of this particulate filter in the exhaust line. The computer can also receive information on the oxygen content of the exhaust gases from a Lambda probe a, designated by the general reference 24 in this figure, integrated in the exhaust line.
En sortie, ce calculateur est adapté pour piloter les moyens d'admission d'air, les moyens de recyclage de gaz d'échappement, le turbocom presseur, les moyens d'ajout au carburant de l'additif, les moyens d'alimentation en carburant de la rampe commune et les différents injecteurs associés aux cy lindres du moteur. At the outlet, this computer is suitable for controlling the air intake means, the exhaust gas recycling means, the pressurized turbocom, the means for adding the additive to the fuel, the means for supplying fuel from the common rail and the various injectors associated with the engine cylinders.
En particulier, ce calculateur est adapté pour déclencher une phase de régénération du filtre à particules par combustion des particules piégées dans celui-ci en enclenchant une phase d'injections multiples de carburant dans les cylindres du moteur pendant leur phase de détente. In particular, this computer is adapted to trigger a regeneration phase of the particle filter by combustion of the particles trapped in it by initiating a phase of multiple injections of fuel into the engine cylinders during their expansion phase.
Les particules émises par le moteur au cours de son fonctionnement sont en effet piégées dans le filtre à particules. II convient alors de régénérer ce lui-ci régulièrement par combustion de ces particules. The particles emitted by the engine during its operation are in fact trapped in the particle filter. It should then be regenerated regularly by combustion of these particles.
Le capteur de température 22 placé entre le catalyseur 6 et le filtre à particules 7 délivre aux moyens de contrôle 17 et plus particulièrement au calcu lateur 18, une information de température du catalyseur en sortie de celui-ci. The temperature sensor 22 placed between the catalyst 6 and the particle filter 7 delivers to the control means 17 and more particularly to the calculator 18, information on the temperature of the catalyst at the outlet thereof.
Le calculateur 18 compare alors cette température en sortie du cataly seur à une valeur de seuil de sécurité pour réguler le fonctionnement du moteur afin d'éviter que la température en sortie du catalyseur ne dépasse ce seuil de sécurité. The computer 18 then compares this temperature at the outlet of the catalyst to a safety threshold value to regulate the operation of the engine in order to prevent the temperature at the outlet of the catalyst from exceeding this safety threshold.
Ceci permet d'éviter toute dégradation du catalyseur. This avoids any degradation of the catalyst.
Le contrôle du fonctionnement du moteur s'opère de façon classique pour réguler cette température. The control of the operation of the engine is carried out in a conventional manner to regulate this temperature.
Ceci est illustré sur la figure 2, sur laquelle on a illustré en 25, l'acquisition de la température en sortie du capteur de température 22, par les moyens de contrôle 17 et plus particulièrement le calculateur 18. Ce calculateur 18 compare alors cette température à une valeur de seuil de sécurité S, en 26, pour réguler si nécessaire en 27, le fonctionnement du moteur et des organes associés à celui-ci afin d'éviter que cette température n'augmente de trop et pro voque une dégradation du catalyseur en dépassant le seuil de sécurité.This is illustrated in FIG. 2, in which there is illustrated at 25, the acquisition of the temperature at the outlet of the temperature sensor 22, by the control means 17 and more particularly the computer 18. This computer 18 then compares this temperature at a safety threshold value S, at 26, to regulate if necessary at 27, the operation of the engine and of the members associated with it in order to prevent this temperature from increasing too much and causing degradation of the catalyst by exceeding the safety threshold.
Cette valeur de seuil de sécurité S peut par exemple être stockée dans les moyens de stockage 19 associés au calculateur 18. This safety threshold value S can for example be stored in the storage means 19 associated with the computer 18.
