Description

1 CULASSE DE MOTEUR THERMIQUE COMPORTANT UN TUBE D'INJECTEUR L'invention1 HEAT ENGINE HEAD COMPRISING AN INJECTOR TUBE The invention

concerne une culasse de moteur thermique de type dit "à injection directe" pour un véhicule automobile.  relates to a so-called "direct injection" type engine cylinder head for a motor vehicle.

L'invention concerne plus particulièrement une culasse qui est traversée par au moins un perçage dans lequel est agencé un injecteur sensiblement cylindrique dont l'extrémité inférieure débouche dans une chambre de combustion du moteur et dont au moins une partie intermédiaire est reçue de manière étanche dans un tube d'injecteur coaxial qui est reçu dans le perçage et qui traverse au moins une cavité de circulation de liquide de refroidissement de la culasse. Les moteurs thermiques qui comportent un injecteur placé en position centrale ou non, et une cavité de circulation de liquide de refroidissement de la culasse, nécessitent, pour que le refroidissement de la culasse s'effectue correctement, une disposition de l'injecteur dans laquelle il traverse ladite cavité de circulation de liquide de refroidissement. Lors d'un démontage ultérieur de l'injecteur, le tube peut sortir de son logement car il peut rester collé à l'injecteur à cause de la calamine qui peut s'interposer et s'accumuler entre la paroi intérieure du tube et l'injecteur. Le document GB299635, par exemple, décrit et représente une configuration dans laquelle le guide interne est formé d'un tube qui est introduit par l'extrémité supérieure du perçage de la culasse. Le tube est maintenu en butée contre une surface de la culasse à l'aide d'un manchon vissé dans une portée cylindrique du perçage définissant un filetage approprié à celui du manchon. Un inconvénient de cette solution est qu'il est nécessaire de réaliser un filetage pour chaque perçage recevant un injecteur. Ceci 2910555 2 présente un coût élevé. De plus, il faut s'assurer que cet assemblage ne se dévisse pas compte tenu de l'environnement particulier de la culasse et notamment des vibrations. Pour y remédier, l'invention propose une culasse de moteur du 5 type décrit précédemment, dans laquelle le manchon est fretté dans une portée cylindrique du perçage. Selon d'autres caractéristiques de l'invention : l'extrémité inférieure du manchon est en appui sur l'extrémité supérieure du tube ; la culasse comporte un injecteur reçu au moins partiellement dans le perçage de la culasse, dont une portion cylindrique est centrée par rapport au diamètre intérieur du manchon fretté ; une portion du tube peut être guidée dans une portée cylindrique du perçage de la culasse par l'intermédiaire d'un ou plusieurs joints toriques qui assurent l'étanchéité au liquide de refroidissement de la cavité ; l'extrémité inférieure du tube peut être frettée dans une portée cylindrique inférieure.  The invention more particularly relates to a yoke which is traversed by at least one bore in which is arranged a substantially cylindrical injector whose lower end opens into a combustion chamber of the engine and at least one intermediate portion is received in a sealed manner in a coaxial injector tube which is received in the bore and passes through at least one cylinder head coolant circulation cavity. The heat engines which comprise an injector placed in a central position or not, and a cylinder head coolant circulation cavity, require, for the cooling of the cylinder head is carried out correctly, a provision of the injector in which it crosses said coolant circulation cavity. During a subsequent disassembly of the injector, the tube can leave its housing because it can remain stuck to the injector because of the scale that can interpose and accumulate between the inner wall of the tube and the injector. GB299635, for example, describes and shows a configuration in which the inner guide is formed of a tube which is introduced through the upper end of the bolt hole. The tube is held in abutment against a surface of the cylinder head using a sleeve screwed into a cylindrical bore of the bore defining a thread suitable for that of the sleeve. A disadvantage of this solution is that it is necessary to make a thread for each piercing receiving an injector. This 2910555 2 has a high cost. In addition, it must be ensured that this assembly does not unscrew due to the particular environment of the cylinder head and in particular vibrations. To remedy this, the invention provides a motor yoke of the type described above, in which the sleeve is hooped in a cylindrical bore of the bore. According to other features of the invention: the lower end of the sleeve bears on the upper end of the tube; the cylinder head comprises an injector at least partially received in the bore of the cylinder head, a cylindrical portion of which is centered with respect to the inside diameter of the shrunk sleeve; a portion of the tube may be guided in a cylindrical bore of the bolt bore via one or more O-rings which seal the coolant of the cavity; the lower end of the tube can be hooped into a lower cylindrical bearing.

20 L'invention concerne également un moteur à combustion interne comportant une telle culasse. D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit pour la compréhension de laquelle on se reportera à l'unique figure 25 représentant une vue schématique en coupe d'une culasse pour un moteur selon l'invention. Dans la description qui va suivre, des chiffres de référence identiques désignent des pièces identiques ou ayant des fonctions similaires.The invention also relates to an internal combustion engine having such a cylinder head. Other features and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the single FIG. 25 showing a schematic sectional view of a cylinder head for an engine according to FIG. invention. In the following description, like reference numerals designate like parts or having similar functions.

10 15 2910555 3 On a représenté à la figure 1 une culasse 1 pour un moteur thermique de véhicule automobile de type dit "à injection directe", c'est à dire comportant un injecteur (non représenté) débouchant directement dans la chambre de combustion du moteur.FIG. 1 shows a cylinder head 1 for a motor vehicle engine of the so-called "direct injection" type, that is to say having an injector (not shown) opening directly into the combustion chamber of the engine. engine.

5 La culasse 1 est traversée par au moins un perçage 2 dans lequel est agencé un injecteur (non représenté) sensiblement cylindrique dont l'extrémité inférieure débouche dans une face inférieure 3 de la culasse 1 communiquant avec une chambre de combustion (non représentée) du moteur.The cylinder head 1 is traversed by at least one bore 2 in which is arranged a substantially cylindrical injector (not shown) whose lower end opens into a lower face 3 of the cylinder head 1 communicating with a combustion chamber (not shown) of the engine.

10 Au moins une partie intermédiaire de l'injecteur est reçue de manière étanche dans un tube 4 coaxial qui est reçu dans le perçage 2 et qui traverse une cavité 24 de circulation de liquide de refroidissement de la culasse 1. Le tube 4 comporte, de part et d'autre de la cavité 24, une 15 extrémité inférieure 41 coaxiale qui peut être fixée par frettage dans une portée cylindrique 21 inférieure associée du perçage 2 de la culasse 1. Une portion 43 du tube 4 peut être guidée dans une portée cylindrique 23 du perçage 2 de la culasse 1 par l'intermédiaire d'un ou plusieurs joints toriques 7 qui assurent 20 l'étanchéité au liquide de refroidissement de la cavité 24. Le tube 4 est maintenu en butée contre une surface de la culasse 1 à l'aide d'un manchon 5 fixé à la culasse 1. La surface correspond dans cet exemple à la surface inférieure de la cavité 24 de circulation de liquide de refroidissement de la culasse 1.At least one intermediate portion of the injector is sealingly received in a coaxial tube 4 which is received in the bore 2 and which passes through a cavity 24 for circulating coolant of the cylinder head 1. The tube 4 comprises on either side of the cavity 24, a coaxial lower end 41 which can be secured by hooping in an associated lower cylindrical bearing surface 21 of the bore 2 of the cylinder head 1. A portion 43 of the tube 4 can be guided in a cylindrical seat 23 of the bore 2 of the cylinder head 1 via one or more O-rings 7 which seal the coolant of the cavity 24. The tube 4 is held in abutment against a surface of the cylinder head 1 to With the aid of a sleeve 5 fixed to the cylinder head 1. In this example, the surface corresponds to the lower surface of the coolant circulation cavity 24 of the cylinder head 1.

25 Selon l'invention, le manchon 5 est fretté dans une portée cylindrique du perçage. La portée cylindrique peut être la portée supérieure 22 du perçage 2 de la culasse 1. Conformément à la figure 1, l'extrémité inférieure du manchon 5 est en appui sur l'extrémité supérieure 42 du tube 1.According to the invention, the sleeve 5 is hooped in a cylindrical bore of the bore. The cylindrical bearing surface may be the upper bearing surface 22 of the bore 2 of the cylinder head 1. According to FIG. 1, the lower end of the sleeve 5 bears against the upper end 42 of the tube 1.

30 Ce montage permet donc de bloquer le tube 4 d'injecteur par un procédé facile à mettre en oeuvre pour le montage du manchon 5.This assembly thus makes it possible to block the injector tube 4 by a method that is easy to implement for mounting the sleeve 5.

2910555 4 Selon une caractéristique supplémentaire de l'invention, l'injecteur qui est monté dans la culasse 1 et qui est reçu au moins partiellement dans le perçage 2 de la culasse 1 comporte une portion cylindrique centrée par rapport au diamètre intérieur du 5 manchon 5 fretté. Le diamètre intérieur du manchon 5 est défini en relation avec le diamètre extérieur de la portion cylindrique de l'injecteur. Un avantage lié à cette caractéristique est qu'on obtient un centrage précis de l'injecteur dans la partie haute de la culasse 1, à la 10 différence d'un assemblage vissé qui possède un jeu.According to a further feature of the invention, the injector which is mounted in the yoke 1 and which is at least partially received in the bore 2 of the yoke 1 has a cylindrical portion centered with respect to the inside diameter of the sleeve 5. hooped. The inside diameter of the sleeve 5 is defined in relation to the outside diameter of the cylindrical portion of the injector. An advantage of this feature is that precise centering of the injector is achieved in the upper part of the cylinder head 1, unlike a screwed assembly which has a clearance.
