Description

La présente invention concerne un agencement pour le maintien et le positionnement angulaire de plusieurs injecteurs de carburant sur un moteur à combustion interne, chaque injecteur étant raccordé par l'une de ses extrémités à une conduite d'alimentation en carburant et par son autre extrémité à une tubulure d'admission d'un cylindre du moteur, chaque injecteur étant fixé au moyen d'une barre de maintien qui comporte des moyens pour assurer sa fixation sur le moteur et dans laquelle sont formées des ouvertures dans chacune desquelles est reçue une portion de profil complémentaire de la paroi externe du corps d'un injecteur.The present invention relates to an arrangement for holding and angular positioning of several fuel injectors on an internal combustion engine, each injector being connected by one of its ends to a fuel supply pipe and by its other end to an intake manifold of a cylinder of the engine, each injector being fixed by means of a holding bar which comprises means for ensuring its fixing on the engine and in which are formed openings in each of which is received a portion of complementary profile of the external wall of the body of an injector.

L'invention concerne plus particulièrement un agencement comportant plusieurs injecteurs de carburant qui permet d'assurer un positionnement et un maintien correct des injecteurs sur le moteur.The invention relates more particularly to an arrangement comprising several fuel injectors which ensures correct positioning and maintenance of the injectors on the engine.

Le document GB-A-2.138.887 décrit et représente un agencement du type mentionné précédemment, mais dans lequel l'orientation angulaire précise des injecteurs n'est pas assurée de manière fiable lors du montage.The document GB-A-2,138,887 describes and represents an arrangement of the type mentioned above, but in which the precise angular orientation of the injectors is not reliably ensured during assembly.

Afin de remédier à cet inconvénient, l'invention propose un agencement, caractérisé en ce que la paroi interne de chaque ouverture comporte au moins une partie plane qui coopère avec un méplat correspondant formé dans ladite portion de la paroi externe du corps de l'injecteur et qui s'étend parallèlement à l'axe de l'injecteur pour orienter angulairement ce dernier par rapport au moteur.In order to remedy this drawback, the invention provides an arrangement, characterized in that the internal wall of each opening comprises at least one flat part which cooperates with a corresponding flat formed in said portion of the external wall of the body of the injector and which extends parallel to the axis of the injector to angularly orient the latter relative to the engine.

Selon d'autres caractéristiques de l'invention :

  • chaque ouverture débouche transversalement pour permettre l'introduction transversale de ladite portion de la paroi externe du corps de l'injecteur dans l'ouverture ;
  • chaque ouverture est délimitée latéralement par deux parties planes parallèles et opposées de sa paroi interne qui coopèrent respectivement avec deux méplats parallèles et opposés formés dans ladite portion de la paroi externe du corps de l'injecteur ;
  • chaque ouverture comporte des moyens de coopération par friction avec la portion de la paroi externe du corps de l'injecteur ;
  • les moyens de coopération par friction sont constitués par des moyens de serrage élastique de la portion de paroi dans son ouverture ;
  • l'ouverture peut présenter une section légèrement inférieure à celle de la portion de la paroi externe du corps de l'injecteur ;
  • les moyens de fixation de la barre sur le moteur comportent deux pattes de fixation espacées latéralement qui sont fixées sur le moteur ; et
  • la conduite d'alimentation des injecteurs est fixée sur les pattes de fixation.
According to other characteristics of the invention:
  • each opening opens transversely to allow the transverse introduction of said portion of the external wall of the body of the injector into the opening;
  • each opening is delimited laterally by two parallel and opposite flat parts of its wall internal which cooperate respectively with two parallel and opposite flats formed in said portion of the external wall of the body of the injector;
  • each opening comprises means of cooperation by friction with the portion of the external wall of the body of the injector;
  • the friction cooperation means are constituted by elastic clamping means of the wall portion in its opening;
  • the opening may have a section slightly smaller than that of the portion of the external wall of the body of the injector;
  • the means for fixing the bar to the engine comprise two laterally spaced fixing lugs which are fixed to the engine; and
  • the injector supply line is fixed to the fixing lugs.

Dans le dispositif d'injection moderne utilisant des injecteurs du type "bi-jets", pour obtenir une efficacité maximum de ce type d'injecteurs, il est nécessaire que leur position angulaire autour de leur axe général soit déterminée avec précision de façon que le point d'impact de chacun des deux jets sur chacune des soupapes d'admission du cylindre soit orienté de façon précise.In the modern injection device using injectors of the "twin-jet" type, to obtain maximum efficiency of this type of injector, it is necessary that their angular position around their general axis be determined with precision so that the point of impact of each of the two jets on each of the cylinder intake valves is precisely oriented.

L'agencement selon l'invention permet également d'assurer cette fonction de positionnement angulaire.The arrangement according to the invention also makes it possible to ensure this angular positioning function.

Dans ce but l'agencement est caractérisé en ce que la paroi interne de chaque ouverture comporte au moins une partie plane qui coopère avec un méplat correspondant formé dans la position de la paroi externe du corps de l'injecteur et qui s'étend parallèlement à l'axe de ce dernier.For this purpose, the arrangement is characterized in that the internal wall of each opening comprises at least one flat part which cooperates with a corresponding flat formed in the position of the wall. external to the injector body and which extends parallel to the axis of the latter.

L'ouverture peut déboucher transversalement pour permettre l'introduction transversale de la portion de la paroi externe du corps de l'injecteur dans l'ouverture, cette dernière pouvant être délimitée latéralement par deux parties planes parallèles et opposées de sa paroi interne qui coopèrent respectivement avec deux méplats parallèles et opposés formés dans la portion de la paroi externe du corps de l'injecteur.The opening can open transversely to allow the transverse introduction of the portion of the external wall of the body of the injector into the opening, the latter being able to be delimited laterally by two parallel and opposite flat parts of its internal wall which cooperate respectively with two parallel and opposite flats formed in the portion of the external wall of the body of the injector.

D'autres avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels :

  • la figure 3 est une vue en section selon la ligne 3-3 de la figure 1 ; et
  • la figure 4 est une vue en coupe partielle par l'axe d'un des injecteurs qui illustre ce dernier en position sur le moteur.
Other advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:
  • Figure 1 is an elevational view of an arrangement according to the invention for positioning and maintaining four injectors aligned;
  • Figure 2 is a partial sectional view along line 2-2 of Figure 1;
  • Figure 3 is a sectional view along line 3-3 of Figure 1; and
  • Figure 4 is a partial sectional view through the axis of one of the injectors which illustrates the latter in position on the engine.

L'agencement 10 représenté aux figures 1 à 3 permet d'assurer le maintien et le positionnement de quatre injecteurs 12 sur un moteur à combustion interne, et notamment sur une tubulure d'admission 14 représentée à la figure 4.The arrangement 10 shown in FIGS. 1 to 3 makes it possible to maintain and position four injectors 12 on an internal combustion engine, and in particular on an intake manifold 14 shown in FIG. 4.

L'extrémité supérieure 16 de chacun des injecteurs 12 est raccordée de manière étanche à une conduite d'alimentation en carburant 18. La conduite 18 est rectiligne et rigide et permet l'alimentation simultanée des quatre injecteurs qui lui sont reliés.The upper end 16 of each of the injectors 12 is tightly connected to a fuel supply line 18. The line 18 is straight and rigid and allows the simultaneous supply of the four injectors which are connected to it.

L'extrémité inférieure 20 de chacun des injecteurs est équipée d'un joint d'étanchéité torique 22 qui est prévu pour être reçu dans un alésage cylindrique correspondant 24 formé dans la tubulure d'admission 14.The lower end 20 of each of the injectors is fitted with an O-ring seal 22 which is designed to be received in a corresponding cylindrical bore 24 formed in the intake manifold 14.

L'agencement 10 est constitué pour l'essentiel par une barre de maintien et de positionnement 26 qui s'étend parallèlement à la conduite rectiligne d'alimentation 18.The arrangement 10 essentially consists of a holding and positioning bar 26 which extends parallel to the straight supply line 18.

Dans le mode de réalisation représenté aux figures, la barre 26 est une pièce en tôle découpée et pliée comportant principalement une partie formant plaque 28 et un bord de renfort replié à angle droit 30.In the embodiment shown in the figures, the bar 26 is a piece of cut and folded sheet metal mainly comprising a plate portion 28 and a reinforcing edge folded at right angles 30.

La barre 26 comporte quatre ouvertures 32 qui sont espacées latéralement le long de la barre 26 de façon à définir les positions latérales relatives des quatre injecteurs 12.The bar 26 has four openings 32 which are laterally spaced along the bar 26 so as to define the relative lateral positions of the four injectors 12.

Chaque ouverture 32 est une ouverture de profil sensiblement carré qui débouche transversalement par un de ses côtés ouvert en direction d'un des bords longitudinaux 34 de la barre 26. Le profil de la section de chacune des ouvertures 32 est complémentaire de celui de la paroi externe 36 de la portion du corps de l'injecteur 12 qui est reçue dans l'ouverture 32.Each opening 32 is an opening with a substantially square profile which opens transversely through one of its open sides towards one of the longitudinal edges 34 of the bar 26. The section profile of each of the openings 32 is complementary to that of the wall external 36 of the portion of the body of the injector 12 which is received in the opening 32.

Dans le mode de réalisation représenté aux figures, la portion de paroi externe 36 est sensiblement rectangulaire et comporte notamment deux méplats parallèles et opposés 38 et 40 qui s'étendent verticalement parallèlement à l'axe général de l'injecteur 12.In the embodiment shown in the figures, the outer wall portion 36 is substantially rectangular and in particular comprises two parallel and opposite flats 38 and 40 which extend vertically parallel to the general axis of the injector 12.

Les deux méplats 38 et 40 sont reçus et serrés élastiquement entre deux parties planes parallèles et opposées, 42 et 44, respectivement, qui délimitent latéralement l'ouverture 32.The two flats 38 and 40 are received and clamped elastically between two parallel and opposite flat parts, 42 and 44, respectively, which laterally define the opening 32.

Afin d'assurer un bon maintien de la portion 36 du corps de l'injecteur, l'écartement latéral entre les deux parties planes 42 et 44, qui s'étendent verticalement vers le bas dans un plan perpendiculaire à celui de la partie formant plaque 28, est légèrement inférieur à la distance latérale séparant les deux méplats 38 et 40.In order to ensure good maintenance of the portion 36 of the body of the injector, the lateral spacing between the two flat parts 42 and 44, which extend vertically downwards in a plane perpendicular to that of the plate part 28, is slightly less than the lateral distance separating the two flats 38 and 40.

Les deux parties planes 42 et 44 forment ainsi une pince de maintien et de positionnement de la portion 36 du corps de l'injecteur 12 avec laquelle elles coopèrent par friction.The two flat parts 42 and 44 thus form a clamp for holding and positioning the portion 36 of the body of the injector 12 with which they cooperate by friction.

Du fait de la coopération des méplats et des parties planes, l'injecteur 12 est parfaitement positionné angulairement autour de son axe général par rapport à la barre 26.Due to the cooperation of the flats and the flat parts, the injector 12 is perfectly angularly positioned around its general axis relative to the bar 26.

Afin d'améliorer encore les qualités de maintien des injecteurs 12 par la barre 26, il est possible de prévoir des stries sur la portion 36, ou sur la paroi interne de l'ouverture 32 qui augmentent la coopération par friction entre ces éléments.In order to further improve the retention qualities of the injectors 12 by the bar 26, it is possible to provide ridges on the portion 36, or on the internal wall of the opening 32 which increase the friction cooperation between these elements.

La barre 26 est équipée de deux pattes de fixation 46 qui sont espacées latéralement le long de la barre 26.The bar 26 is equipped with two fixing lugs 46 which are spaced laterally along the bar 26.

Chacune des pattes 46 assure une double fonction.Each of the legs 46 performs a double function.

A cet effet chaque patte 46 comporte deux portions de pattes en forme de L 48 et 50 qui sont reliées entre elles par leurs branches verticales 52 et 54, par exemple par soudage.To this end, each lug 46 has two portions of L-shaped lugs 48 and 50 which are connected together by their vertical branches 52 and 54, for example by welding.

La première portion de patte 48 comporte dans sa branche horizontale 56 un trou 58 dans lequel peut pénétrer une vis de fixation 60 de la patte 46 sur le conduit d'admission 14.The first leg portion 48 has in its horizontal branch 56 a hole 58 into which a fixing screw 60 of the leg 46 can penetrate on the intake duct 14.

La seconde portion de patte 50 comporte dans sa branche horizontale 62 un trou 64 qui permet d'assurer la fixation de la patte 46 sur la barre 26 au moyen d'une liaison filetée vis-écrou 66.The second leg portion 50 has in its horizontal branch 62 a hole 64 which makes it possible to secure the tab 46 on the bar 26 by means of a threaded screw-nut connection 66.

La patte 46 permet donc d'assurer le positionnement et la fixation de la barre 26 sur le moteur à combustion interne.The tab 46 therefore makes it possible to ensure the positioning and the fixing of the bar 26 on the internal combustion engine.

Selon une autre caractéristique de l'invention, la branche verticale 52 de la première portion 48 de la patte de fixation 46 reçoit à son extrémité supérieure 68 la conduite d'alimentation en carburant 18 qui peut lui être fixée par tous moyens appropriés tels que par exemple des attaches élastiques (non représentées).According to another characteristic of the invention, the vertical branch 52 of the first portion 48 of the fixing lug 46 receives at its upper end 68 the fuel supply line 18 which can be fixed to it by any suitable means such as by example of elastic fasteners (not shown).

On comprend donc aisément que l'agencement qui vient d'être décrit permet d'assurer le positionnement et le maintien correct des injecteurs sur le conduit d'admission 14 d'un moteur à combustion interne, l'ensemble constitué par la conduite d'alimentation 18, la barre 26, et les injecteurs 12 pouvant être réalisé lors d'une phase d'assemblage préalable et de réglage précis des différents positionnements.It is therefore easily understood that the arrangement which has just been described makes it possible to ensure the correct positioning and maintenance of the injectors on the intake duct 14 of an internal combustion engine, the assembly formed by the duct of supply 18, bar 26, and injectors 12 can be produced during a prior assembly phase and precise adjustment of the different positions.

A titre de variante non représentée, il est également possible de prévoir l'interposition de moyens élastiques, tels que par exemple des plaques de caoutchouc, entre les méplats 38 et 40 et les parties planes 42 et 44.As a variant not shown, it is also possible to provide for the interposition of elastic means, such as for example rubber plates, between the flats 38 and 40 and the flat parts 42 and 44.

La barre 26 qui, dans le mode de réalisation représenté, est une plaque en tôle découpée et pliée peut bien entendu être réalisée en fil plié, en matière plastique, etc...The bar 26 which, in the embodiment shown, is a cut and folded sheet metal plate can of course be made of folded wire, plastic material, etc.
