COMPOSANT DE LIGNE D'ECHAPPEMENTEXHAUST LINE COMPONENT

La présente invention concerne un composant de ligne d'échappement d'un moteur à combustion interne de véhicule automobile, qui est destiné à recevoir un injecteur.  The present invention relates to an exhaust line component of a motor vehicle internal combustion engine, which is intended to receive an injector.

Il est connu de placer un injecteur additionnel de carburant dans la ligne d'échappement du moteur. Plus précisément, l'injecteur est fixé sur le composant et l'extrémité de l'injecteur se trouve dans une cavité du composant pour injecter du carburant à l'intérieur du composant. Lorsque l'extrémité de l'injecteur se trouve dans un composant de ligne d'échappement qui est éloigné du moteur, comme c'est le cas par exemple lorsqu'il est placé en aval de la turbine du turbocompresseur du moteur, on constate qu'elle peut s'encrasser. De plus, l'extrémité de l'injecteur est très sollicitée thermiquement par les gaz d'échappement, et cela nuit et peut détériorer cet injecteur. Un objectif de la présente invention est de proposer un composant de ligne d'échappement qui protège l'extrémité de l'injecteur contre l'encrassement et contre les gaz d'échappement. Pour cela, l'invention concerne un composant de ligne d'échappement d'un moteur à combustion interne, le composant définissant une l'entrée et une sortie pour le passage d'un flux de gaz d'échappement, une cavité formée dans la paroi du composant pour recevoir l'extrémité d'un injecteur destiné à être fixé sur le composant ; selon l'invention, le composant comporte un déflecteur placé en amont de la cavité, et dépassant de la surface intérieure du composant pour dévier le flux de gaz de l'extrémité de l'injecteur. Selon une autre caractéristique de l'invention, le composant peut comporter une partie moulée, et le déflecteur peut être venu de matière avec la partie moulée.  It is known to place an additional fuel injector in the exhaust line of the engine. Specifically, the injector is attached to the component and the end of the injector is in a cavity of the component for injecting fuel into the component. When the end of the injector is in an exhaust line component which is remote from the engine, as is the case for example when it is placed downstream of the turbocharger turbine of the engine, it is found that it can get dirty. In addition, the end of the injector is very thermally stressed by the exhaust gas, and it harms and can damage this injector. An object of the present invention is to provide an exhaust line component which protects the end of the injector against fouling and against exhaust gases. For this, the invention relates to an exhaust line component of an internal combustion engine, the component defining an inlet and an outlet for the passage of an exhaust gas stream, a cavity formed in the component wall for receiving the end of an injector for attachment to the component; according to the invention, the component comprises a deflector placed upstream of the cavity, and protruding from the inner surface of the component to deflect the flow of gas from the end of the injector. According to another characteristic of the invention, the component may comprise a molded part, and the deflector may be integral with the molded part.

Le composant selon l'invention et ses avantages seront mieux compris à la lecture de la description détaillée de modes de réalisation pris à titre d'exemples et nullement limitatifs, et illustrés par les dessins sur lesquels : la figure 1 représente une vue en coupe longitudinale du composant selon l'axe A-A des figures 2 et 4 la figure 2 est une vue en coupe longitudinale selon l'axe B-B de la figure 1 la figure 3 est une vue en coupe d'un premier mode de réalisation selon l'axe C-C de la figure 2 la figure 4 est une vue en coupe d'un deuxième mode de réalisation selon l'axe B-B de la figure 1 En référence à la figure 1, le composant 1 de ligne d'échappement d'un moteur à combustion interne est destiné à recevoir un injecteur 3. L'injecteur 3 peut être fixé sur le composant par l'intermédiaire d'un support 10. Le composant définit une l'entrée E et une sortie S pour le passage d'un flux de gaz d'échappement. Une flèche montre le sens du flux de gaz d'échappement, de l'entrée E vers la sortie S. Le composant 1 définit également une cavité 2 formée dans la paroi 7 du composant 1 pour recevoir l'extrémité 4 de l'injecteur 3 destiné à être fixé sur le composant 1. Conformément à l'invention, pour protéger l'extrémité 4 de l'injecteur 3 contre l'encrassement et contre les gaz d'échappement, le composant 1 comporte un déflecteur placé en amont de la cavité 2, et dépassant de la surface intérieure 6 du composant 1. Le déflecteur est placé en amont de la cavité 2 pris par rapport au sens de déplacement du flux de gaz, c'est-à-dire qu'il est placé du côté de l'entrée E du composant 1. Le déflecteur permet de dévier le flux de gaz de l'extrémité 4 de l'injecteur 3. La vitesse des gaz d'échappement au niveau de l'extrémité 4 est ainsi abaissée, et ceci permet de protéger l'extrémité 4 de l'injecteur 3 contre l'encrassement et aussi contre la température parfois très élevée des gaz d'échappement. Par extrémité 4, il convient d'entendre l'extrémité de la buse de l'injecteur 3, par laquelle le carburant est injecté dans le composant 1 pour se mélanger aux gaz d'échappement. Selon une caractéristique supplémentaire mais non limitative de l'invention, le composant 1 peut comporter une partie moulée, le déflecteur pouvant alors être venu de matière avec la partie moulée.  The component according to the invention and its advantages will be better understood on reading the detailed description of embodiments taken by way of examples and in no way limiting, and illustrated by the drawings in which: FIG. 1 represents a longitudinal sectional view of the component along the axis AA of Figures 2 and 4 Figure 2 is a longitudinal sectional view along the axis BB of Figure 1 Figure 3 is a sectional view of a first embodiment along the axis CC FIG. 4 is a sectional view of a second embodiment along the axis BB of FIG. 1. With reference to FIG. 1, the component 1 of the exhaust line of an internal combustion engine is intended to receive an injector 3. The injector 3 can be fixed on the component via a support 10. The component defines an input E and an output S for the passage of a gas flow. 'exhaust. An arrow shows the direction of the flow of exhaust gas, from the inlet E to the outlet S. The component 1 also defines a cavity 2 formed in the wall 7 of the component 1 to receive the end 4 of the injector 3 intended to be fixed on the component 1. According to the invention, to protect the end 4 of the injector 3 against fouling and against the exhaust gas, the component 1 comprises a deflector placed upstream of the cavity 2, and protruding from the inner surface 6 of the component 1. The deflector is placed upstream of the cavity 2 taken with respect to the direction of movement of the gas flow, that is to say that it is placed on the side of the inlet E of the component 1. The deflector makes it possible to deflect the flow of gas from the end 4 of the injector 3. The speed of the exhaust gases at the end 4 is thus lowered, and this makes it possible to protect the end 4 of the injector 3 against fouling and also against the temperature pa sometimes very high exhaust. By end 4, it is to be understood the end of the nozzle of the injector 3, through which the fuel is injected into the component 1 to mix with the exhaust gas. According to an additional but non-limiting feature of the invention, the component 1 may comprise a molded part, the deflector then being integral with the molded part.

Un avantage de réaliser cette partie par moulage est qu'il est possible de réaliser en même temps le déflecteur sans avoir à rajouter et à fixer une pièce supplémentaire. Cette partie moulée peut correspondre à un cône de sortie qui peut se raccorder à une structure comportant un catalyseur d'oxydation (non représenté). Selon un premier mode de réalisation représenté aux figures 1 2 et 3, le déflecteur peut comporter une protubérance 8 qui s'étend transversalement par rapport au flux de gaz d'échappement. Sur la figure 2, la protubérance 8 est droite et s'étend perpendiculairement à la direction du flux de gaz imposé par le composant 1. Dans ce mode de réalisation, le profil de la protubérance 8 comporte une portion inclinée suivie d'une portion arrondie se raccordant à la surface intérieure 6 et à la cavité 2. Ce profil présente l'avantage d'être de conception simple, de limiter les pertes de charge dues à cette protubérance et aussi d'éviter que des suies ne viennent s'agglomérer sur la protubérance 8.  An advantage of making this part by molding is that it is possible to achieve at the same time the deflector without having to add and fix an additional piece. This molded part may correspond to an outlet cone which can be connected to a structure comprising an oxidation catalyst (not shown). According to a first embodiment shown in FIGS. 1 2 and 3, the deflector may comprise a protuberance 8 which extends transversely with respect to the flow of exhaust gas. In FIG. 2, the protuberance 8 is straight and extends perpendicular to the direction of the gas flow imposed by the component 1. In this embodiment, the profile of the protuberance 8 comprises an inclined portion followed by a rounded portion. this profile has the advantage of being of simple design, to limit the pressure drops due to this protuberance and also to prevent soot from coming to agglomerate on the inner surface 6 and the cavity 2. This profile has the advantage of being of simple design the protuberance 8.

Selon la deuxième mode de réalisation illustré aux figures 1 et 4, le déflecteur peut comporter une protubérance 9 entourant au moins partiellement la cavité 2, par exemple la moitié la cavité 2. Sur la figure 1, la protubérance 9 est représenté en pointillés et reprend aussi le profil de la coupe de la protubérance 8. Dans ce mode de réalisation, le profil de la protubérance 9 comporte une portion inclinée suivie d'une portion arrondie se raccordant à la cavité 2. Ce profil présente l'avantage de limiter les pertes de charge dues à cette protubérance et aussi d'éviter que des suies ne viennent s'agglomérer sur la protubérance 9. Un autre avantage de ce mode de réalisation est que les pertes de charges sont diminuées tout en optimisant la protection autour de l'extrémité de l'injecteur. Dans ces deux modes de réalisation, l'injecteur 3 peut être fixé sur le composant 1 de telle manière que son extrémité 4 se trouve dans la cavité 2 à une hauteur inférieure à la hauteur du déflecteur.  According to the second embodiment illustrated in Figures 1 and 4, the baffle may comprise a protuberance 9 at least partially surrounding the cavity 2, for example half the cavity 2. In Figure 1, the protuberance 9 is shown in dotted lines and resumes also in this embodiment, the profile of the protrusion 9 comprises an inclined portion followed by a rounded portion connecting to the cavity 2. This profile has the advantage of limiting losses load due to this protrusion and also to prevent soot come to agglomerate on the protrusion 9. Another advantage of this embodiment is that the pressure losses are reduced while optimizing the protection around the end of the injector. In these two embodiments, the injector 3 can be fixed on the component 1 so that its end 4 is in the cavity 2 at a height less than the height of the deflector.

D'autres variantes et modes de réalisation peuvent être envisagés. Par exemple le déflecteur peut comporter un élément de tôle soudé (non représenté) sur la surface intérieure 6 du composant 1 en amont de la cavité 2.  Other variants and embodiments may be envisaged. For example, the deflector may comprise a welded sheet metal element (not shown) on the inner surface 6 of the component 1 upstream of the cavity 2.
