Description

DISPOSITIF DE FIXATION D'UN ORGANE DE DEPOLLUTION SUR UNDEVICE FOR FIXING A DEPOLLUTION MEMBER ON A

BLOC CYLINDRE DE MOTEUR A COMBUSTION  COMBUSTION ENGINE CYLINDER BLOCK

La présente invention concerne un moteur à combustion interne comportant un organe de dépollution, tel qu'un catalyseur, et un système de recirculation.  The present invention relates to an internal combustion engine comprising an abatement member, such as a catalyst, and a recirculation system.

Plus précisément, elle a pour objet un dispositif de fixation d'un organe de dépollution sur un carter cylindre de moteur à combustion disposant d'un circuit de recirculation des gaz d'échappement muni d'un refroidisseur.  More specifically, it relates to a device for fixing a pollution control member on a combustion engine cylinder block having an exhaust gas recirculation circuit provided with a cooler.

Les gaz d'échappement réintroduits dans la chambre de combustion d'un moteur, visent à réduire la température maximale de combustion. Leur refroidissement améliore la performance du système de recirculation, en limitant le réchauffement des gaz à l'admission.  The exhaust gases reintroduced into the combustion chamber of an engine, aim to reduce the maximum combustion temperature. Their cooling improves the performance of the recirculation system by limiting the heating of the gases at the intake.

Le refroidissement des gaz d'échappement, avant leur retour à l'admission, impose l'intégration d'un refroidisseur dans le circuit de recirculation, et l'implantation de cet élément supplémentaire dans un environnement déjà très contraint.  The cooling of the exhaust gases, before their return to admission, requires the integration of a cooler in the recirculation circuit, and the implementation of this additional element in an already very constrained environment.

Le montage du catalyseur, s'effectue généralement au moyen de béquilles en tôle, sur le bloc cylindre. Selon une disposition connue, le refroidisseur d'échappement peut être fixé sur le collecteur d'échappement, ou le carter cylindre, au moyen de pattes de fixation indépendantes du catalyseur.  The mounting of the catalyst is generally carried out by means of sheet metal legs on the cylinder block. According to a known arrangement, the exhaust cooler can be attached to the exhaust manifold, or the cylinder block, by means of fasteners independent of the catalyst.

La publication FR 2856 735 montre en particulier un système de fixation de catalyseur associé au turbocompresseur. Ce système n'utilise pas de béquilles, mais des colliers vissés sur un support commun du turbocompresseur et du catalyseur sur bloc cylindre du moteur. Toutefois, il ne prévoit pas d'associer la fixation du catalyseur et celle d'un refroidisseur de gaz d'échappement en recirculation.  The publication FR 2856 735 shows in particular a catalyst attachment system associated with the turbocharger. This system does not use crutches, but collars screwed on a common support of the turbocharger and engine cylinder block catalyst. However, it does not provide to associate the attachment of the catalyst and that of an exhaust gas cooler in recirculation.

L'augmentation de volume des composants, qui est imposée par l'évolution des normes de dépollution, conduit à rechercher de nouveaux agencements. Ces agencements doivent en particulier répondre aux cahiers des charges dynamiques et thermomécaniques des éléments concernés, et tenir compte du manque d'accessibilité au carter cylindre.  The increase in volume of the components, which is imposed by the evolution of the standards of depollution, leads to search for new arrangements. These arrangements must in particular meet the dynamic and thermomechanical specifications of the elements concerned, and take into account the lack of accessibility to the cylinder block.

Dans ce but, l'invention propose un dispositif de fixation comprenant au moins deux brides de support d'un refroidisseur de gaz d'échappement en recirculation, une première languette d'appui de l'organe de dépollution reposant contre les brides du refroidisseur, et des sangles de fixation de l'organe de dépollution, l'ensemble constitué par les brides, la languette et les sangles, étant traversé par des vis de fixation sur le carter cylindre du moteur.  For this purpose, the invention proposes a fixing device comprising at least two support flanges of a recirculating exhaust gas cooler, a first support tab of the depollution device resting against the flanges of the cooler, and straps for fixing the depollution member, the assembly constituted by the flanges, the tongue and the straps being traversed by fixing screws on the cylinder block of the engine.

De préférence, le dispositif comporte aussi deux éléments d'appui tubulaires de même longueur que les brides, une deuxième languette d'appui reposant contre les éléments tubulaires, et des sangles de fixation de l'organe de dépollution, l'ensemble constitué par les éléments tubulaires, la languette et les sangles, étant traversé par des vis de fixation sur le carter cylindre du moteur.  Preferably, the device also comprises two tubular support elements of the same length as the flanges, a second support tongue resting against the tubular elements, and straps for fixing the depollution device, the assembly constituted by the tubular elements, the tongue and the straps, being traversed by fixing screws on the cylinder block of the engine.

D'autres caractéristiques et avantages de la présente invention ressortiront clairement de la description suivante d'un mode de réalisation non limitatif de celle-ci, en se reportant aux dessins annexés, sur lesquels - la figure 1 est une vue en perspective du dispositif proposé sans l'organe de dépollution, et - la figure 2 est une vue latérale du même dispositif, avec l'organe de dépollution, Le dispositif de fixation illustré par les figures comprend des vis de fixation 1, deux languettes d'appui 2a, 2b d'un l'organe de dépollution 3, tel qu'un catalyseur, et un refroidisseur 4 de gaz de recirculation ou gaz EGR (Exhaust Gas Recirculation). Le refroidisseur 4 comprend, à chacune de ses deux extrémités, une bride de fixation 6a, 6b, respectivement la bride d'entrée et la bride de sortie du refroidisseur 4. Les deux brides 6a, 6b sont traversées par des trous de passage pour les vis de fixation 1 de l'organe de dépollution sur le carter cylindre (non représenté) du moteur.  Other features and advantages of the present invention will become clear from the following description of a non-limiting embodiment thereof, with reference to the accompanying drawings, in which - Figure 1 is a perspective view of the proposed device. without the depollution device, and - Figure 2 is a side view of the same device, with the depollution member, The fixing device illustrated in the figures comprises fixing screws 1, two support tongues 2a, 2b a pollution control member 3, such as a catalyst, and a cooler 4 recirculating gas or gas EGR (Exhaust Gas Recirculation). The cooler 4 comprises, at each of its two ends, a fixing flange 6a, 6b, respectively the inlet flange and the outlet flange of the cooler 4. The two flanges 6a, 6b are traversed by passage holes for the fixing screw 1 of the pollution control member on the cylinder block (not shown) of the engine.

Le dispositif de fixation comprend également quatre sangles 8 traversées par les vis de fixation 1, à une de leurs extrémités. Les sangles 8 entourent l'organe de dépollution 3, et sont retenues par les languettes de maintien 2a, 2b. 5ur les schémas, deux sangles 8 sont prisonnières entre la languette supérieure 2a et les brides 6a, 6b du refroidisseur. Deux autres sangles 8 sont prisonnières entre la languette inférieure 2b et des éléments tubulaires 9. Les éléments tubulaires 9 ont la même longueur que les brides 6a et 6b.  The fixing device also comprises four straps 8 traversed by the fixing screws 1 at one of their ends. The straps 8 surround the depollution device 3, and are retained by the holding tongues 2a, 2b. In the drawings, two straps 8 are trapped between the upper tongue 2a and the flanges 6a, 6b of the cooler. Two other straps 8 are trapped between the lower tongue 2b and tubular elements 9. The tubular elements 9 have the same length as the flanges 6a and 6b.

Comme indiqué sur le schéma, des vis de fixation 1 traversent les brides 6a, 6b du refroidisseur 4, et la languette supérieure 2a, tandis que d'autres vis 1 traversent les éléments tubulaires 9 et la languette inférieure 2b.  As shown in the diagram, fixing screws 1 pass through the flanges 6a, 6b of the cooler 4, and the upper tongue 2a, while other screws 1 pass through the tubular elements 9 and the lower tongue 2b.

Ainsi, une première languette 2a est en appui contre le refroidisseur 4, et l'autre 2b est en appui contre les éléments tubulaires 9.  Thus, a first tongue 2a is in abutment against the cooler 4, and the other 2b is in abutment against the tubular elements 9.

A leur autre extrémité, les sangles 8, peuvent être accrochées par deux sur un dispositif commun de mise en tension 11. 5ur les schémas, les deux dispositifs de mise en tension 11 des sangles 8 comportent des vis de serrage 12.  At their other end, the straps 8 can be hung in pairs on a common tensioning device 11. In the diagrams, the two tensioning devices 11 of the straps 8 comprise clamping screws 12.

La mise en tension des sangles est alors assurée en serrant les vis 12, après avoir mis en place l'organe de dépollution contre les languettes. Cependant, sans sortir du cadre de l'invention, on peut adapter d'autres systèmes de mise en tension, sans vis de serrage.  The tensioning of the straps is then ensured by tightening the screws 12, after having put in place the depollution member against the tongues. However, without departing from the scope of the invention, other tensioning systems can be adapted without tightening screws.

L'ensemble constitué par le refroidisseur 4, ses brides de fixation 6a, 6b, la languette supérieure 2a, et deux sangles supérieures 8, forme la partie haute du dispositif. Celle-ci peut se présenter en une seule pièce, qui peut être fixée rigidement sur le carter cylindre par des vis de montage 13, avant la mise en place de l'organe de dépollution 3.  The assembly constituted by the cooler 4, its fixing flanges 6a, 6b, the upper tongue 2a, and two upper straps 8, forms the upper part of the device. This can be in one piece, which can be fixed rigidly on the cylinder block by mounting screws 13, before the introduction of the depollution device 3.

Comme la partie haute, la partie basse du dispositif de fixation, constituée par les éléments tubulaires 9, deux sangles inférieures 8, et la languette inférieure 2b, peut aussi former une seule pièce, qui peut être fixée par des vis de montage 13 sur le carter cylindre, avant de mettre en place l'organe de dépollution 3.  As the upper part, the lower part of the fixing device, constituted by the tubular elements 9, two lower straps 8, and the lower tongue 2b, can also form a single piece, which can be fixed by mounting screws 13 on the cylinder block, before putting in place the depollution device 3.

Au montage, l'organe de dépollution 3 est introduit entre les deux parties du dispositif déjà montées sur le carter cylindre. Les sangles 8 sont alors refermées à leur extrémité libre, et mises en tension par les vis de serrage 12 du dispositif 11, ou tout autre dispositif de mise en tension.  During assembly, the depollution device 3 is introduced between the two parts of the device already mounted on the cylinder block. The straps 8 are then closed at their free end, and put in tension by the clamping screws 12 of the device 11, or any other tensioning device.

Dans la description ci-dessus et sur les schémas, l'organe de dépollution fixé sur le carter cylindre est un catalyseur de type non précisé. Bien entendu l'invention s'applique dans les mêmes conditions à la fixation de tout type d' organe de dépollution ou de catalyseur, tel qu'un catalyseur trois voies, ou d'autres organes de dépollution, comme un catalyseur piégeant les oxydes d'azote (Noxtrap).  In the above description and in the drawings, the pollution control member fixed on the cylinder block is a catalyst of unspecified type. Of course, the invention applies under the same conditions to the attachment of any type of pollution control member or catalyst, such as a three-way catalyst, or other pollution control organs, such as a catalyst trapping the oxides of carbon dioxide. nitrogen (Noxtrap).
