Description

Die vorliegende Erfindung betrifft eine Saugrohr-Zylinderkopfanordnung gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to an intake manifold cylinder head assembly according to the preamble of claim 1.

Derartige Anordnungen mit Saugrohr und Zylinderkopf kommen zur Entlüftung des Kurbelgehäuses von Brennkraftmaschinen zum Einsatz. Über diese werden Verbrennungsgase, welche in den Brennräumen der Brennkraftmaschine entstehen und die an den Kolbenringen vorbei in das Kurbelgehäuse gelangen, zur Weiterverwendung weitergeleitet. Solche Gase nennt man auch "Blow-by-Gase". Diese Gase können mittels einer Ansaugleitung, zum Beispiel in Form eines Saugrohres oder eines Ansaugrohres, abgesaugt werden, um diese der Brennkraftmaschine erneut zuzuführen. Hierzu ist ein Saugrohr, welches an der Brennkraftmaschine angeordnet ist, fluidisch mit einer Gasrückführleitung eines Zylinderkopfes fluidisch verbunden. Hierbei ist es besonders wichtig, dass zur Vermeidung von Leistungsausfällen das Saugrohr optimal an dem Verbrennungsmotor oder der Brennkraftmaschine angeordnet ist und so eine dichte Schnittstelle zwischen Zylinderkopf und Saugrohr zur abdichtenden Weiterleitung des Gases geschaffen wird.Such arrangements with intake manifold and cylinder head are used for venting of the crankcase of internal combustion engines. About this combustion gases, which arise in the combustion chambers of the engine and pass the piston rings in the crankcase, forwarded for further use. Such gases are also called "blow-by gases". These gases can be sucked off by means of a suction line, for example in the form of a suction pipe or an intake pipe, in order to supply these again to the internal combustion engine. For this purpose, a suction pipe, which is arranged on the internal combustion engine, fluidly connected to a gas return line of a cylinder head. It is particularly important that in order to avoid power failures, the intake manifold is optimally arranged on the internal combustion engine or the internal combustion engine and so a dense interface between the cylinder head and intake manifold for sealing transmission of the gas is created.

Ein gattungsbildendes Kurbelgehäuseentlüftungssystem ist beispielsweise der DE 10 2004 012 160 A1 zu entnehmen.A generic crankcase ventilation system is, for example, the DE 10 2004 012 160 A1 refer to.

Es ist bekannt, zur exakten Positionierung des Saugrohrs oder der Saugrohrvorrichtung an dem Zylinderkopf der Brennkraftmaschine, dass der Zylinderkopf einen Flansch oder Einlassflansch aufweist, in dem mindestens zwei Bohrungen ausgebildet sind, in die zwei Positionierungselemente des Saugrohrs eingreifen. Weiterhin weist der Flansch für die Gaseinleitung aus der Kurbelgehäuseentlüftung über den Zylinderkopf und dessen Gasrückführleitung eine zusätzliche dritte Bohrung auf. Diese stellt einen Verbindungskanal zwischen der Gasrückführleitung des Zylinderkopfes und der Saugrohrleitung dar, das heißt die dritte Bohrung verbindet als Kanal oder Kanalabschnitt die Gasrückführleitung mit dem Saugrohr.It is known for the exact positioning of the intake manifold or the intake manifold device on the cylinder head of the internal combustion engine, in that the cylinder head has a flange or inlet flange, in which at least two bores are formed, in which two positioning elements of the suction pipe engage. Furthermore, the flange for the gas inlet from the crankcase ventilation via the cylinder head and the gas return line on an additional third hole. This represents a connecting channel between the gas return line of the cylinder head and the suction pipe, that is, the third bore connects as a channel or channel portion, the gas return line to the suction pipe.

Hierbei sind drei Bohrungen nachträglich in den Flansch des Motors einzubringen. Dies führt zu einem hohen Bearbeitungsaufwand. Zudem ist die als Kanal ausgebildete dritte Bohrung so auszubilden, dass sie die Gasrückführleitung und das Saugrohr fluidisch verbindet, was ein hohes Maß an Präzision erfordert.Here, three holes are subsequently introduced into the flange of the engine. This leads to a high processing cost. In addition, the third hole formed as a channel is to be formed so that it fluidly connects the gas return line and the suction tube, which requires a high degree of precision.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Saugrohr-Zylinderkopfanordnung zu schaffen, welche eine einfache und Platz sparende Anbindung des Saugrohrs an den Zylinderkopf ermöglicht, wobei gleichzeitig eine genaue Zentrierung ohne aufwendige Präzisionsarbeiten realisierbar ist.It is therefore an object of the present invention to provide an intake manifold cylinder head assembly, which allows a simple and space-saving connection of the intake manifold to the cylinder head, at the same time a precise centering can be realized without expensive precision work.

Diese Aufgabe wird ausgehend von einer Saugrohr-Zylinderkopfanordnung gemäß dem Oberbegriff des Anspruchs 1 in Verbindung mit dessen kennzeichnenden Merkmalen gelöst. Die nachfolgenden abhängigen Ansprüche geben vorteilhafte Weiterbildungen der Erfindung wieder.This object is achieved on the basis of an intake manifold cylinder head assembly according to the preamble of claim 1 in conjunction with its characterizing features. The following dependent claims give advantageous developments of the invention.

Die Erfindung schließt die technische Lehre ein, dass bei einer Saugrohr-Zylinderkopfanordnung für einen Verbrennungsmotor eines Kraftfahrzeugs mit wenigstens einer ein Saugrohr aufweisenden Saugrohrvorrichtung, welche über einen eine Positionierausnehmungen umfassenden Flansch an einen mit den Ausnehmungen korrespondierenden Positionierelemente aufweisenden Zylinderkopf angeordnet ist, welcher eine Gasrückführleitung umfasst, welche eine Verbindung zwischen dem Kurbelwellenraum und dem Saugrohr herstellt, wobei die Verbindung über eine oder mehrere der Positionierausnehmungen verläuft.The invention includes the technical teaching that in an intake manifold cylinder head assembly for an internal combustion engine of a motor vehicle with at least one intake manifold having a Saugrohrvorrichtung, which is arranged over a Flange comprising a Positionierausnehmungen to a corresponding with the recesses positioning cylinder head, which comprises a gas recirculation line , which is a connection between the crankshaft space and the suction tube produces, wherein the compound extends over one or more of the positioning.

Die erfindungsgemäße Saugrohr-Zylinderkopfanordnung umfasst einen Zylinderkopf und eine Saugrohrvorrichtung mit mindestens einem Saugrohr, die bevorzugt als Saugrohrverteiler ausgebildet ist. Zur Anbindung der Saugrohrvorrichtung an den Zylinderkopf weist der Zylinderkopf seitlich einen Flansch auf. An diesem Flansch sind Positionierausnehmungen sowie weitere Ausnehmungen zur weiteren Befestigung und/oder Fixierung der Saugrohrvorrichtung an dem Zylinderkopf vorgesehen. Zusätzlich münden in den Flansch, genauer dessen eben ausgebildeter und geneigter Oberfläche die Gasrückführleitung(en).The intake manifold cylinder head assembly according to the invention comprises a cylinder head and a Saugrohrvorrichtung with at least one suction pipe, which is preferably designed as Saugrohrverteiler. For connecting the intake manifold to the cylinder head, the cylinder head has a flange on the side. Positioning recesses and further recesses for further fastening and / or fixing of the intake manifold device to the cylinder head are provided on this flange. In addition, the gas recirculation line (s) open into the flange, to be more precise its newly formed and inclined surface.

Für die genaue Positionierung des Saugrohres bzw. der Saugrohrvorrichtung an dem Zylinderkopf sind mindestens zwei Positionierausnehmungen notwendig. Dadurch, dass eine der Positionierausnehmungen als fluidische Verbindung zwischen Gasrückführleitung und Saugrohr ausgebildet ist, kann eine dritte, separate Bohrung zur fluidischen Verbindung entfallen, was eine Minimierung des Nachbearbeitungsaufwand bedeutet, ohne die genaue Positionierung zu beeinträchtigen. Durch die Möglichkeit auf eine dritte Bohrung zu verzichten vergrößert sich der Bereich für Öffnungen und Anbindungen zu anderen Zwecken.For the exact positioning of the intake manifold or the intake manifold on the cylinder head at least two Positionierausnehmungen are necessary. Characterized in that one of the positioning is formed as a fluidic connection between the gas return line and the suction pipe, a third, separate bore for fluidic connection can be omitted, which means minimizing the Nachbearbeitungsaufwand without affecting the exact positioning. The possibility of dispensing with a third bore increases the area for openings and connections for other purposes.

Bevorzugt ist, dass mindestens eine der Positionierausnehmungen zur fluidischen Verbindung nach Art eines Sacklochs ausgebildet ist. Diese ist einfach herzustellen und bietet neben der Möglichkeit standardmäßige Verbindungs- oder Positionierelemente wie Stifte und dergleichen zu Verwenden, die Möglichkeit, eine vorbestimmte Tiefe der Positionierausnehmung exakt einzuhalten. Somit kann die Positionierausnehmung genau auf in dem Zylinderkopf verlaufende Kanäle oder Leitungen abgestimmt werden.It is preferred that at least one of the positioning recesses is designed for the fluidic connection in the manner of a blind hole. This is easy to manufacture and, in addition to the possibility of using standard connection or positioning elements such as pins and the like, offers the possibility of exactly maintaining a predetermined depth of the positioning recess. Thus, the positioning recess can be precisely tuned to running in the cylinder head channels or lines.

Weiter bevorzugt ist, dass die Gasrückführleitung nahe dem Bodenbereich der sacklochförmigen Positionierausnehmung in die Positionierausnehmung mündet. Der Bodenbereich ist der Bereich, in dem die Positionierausnehmung, die von einer Außenseite beginnen ausgebildet wird, endet.It is further preferred that the gas return line opens into the positioning recess near the bottom region of the blind-hole-shaped positioning recess. The floor area is the area in which the positioning recess, which is formed starting from an outside, ends.

Durch die Mündung der Gasrückführleitung in dem Bodenbereich kann ein Großteil der Positionierausnehmung mit einem Positionierelement zusammenwirken und nur ein geringer Bereich, der für die Positionierung und/oder Befestigung des Positionierelements bzw. für das Zusammenwirken von Positionierelement und Positionierausnehmung weniger wirkungsvoll ist, kann für den Durchlass des Fluids oder strömenden Mediums genutzt werden. Somit ergibt sich durch die sacklochförmige Ausbildung der Positionierausnehmung und der Mündung in den Bodenbereich der Positionierausnehmung eine optimale Ausnutzung der Positionierausnehmung und eine kompakte Bauweise.Through the mouth of the gas recirculation line in the bottom region, a large part of the positioning recess can cooperate with a positioning element and only a small area, which is less effective for the positioning and / or fastening of the positioning element or for the interaction of the positioning element and the positioning recess, can be used for the passage be used of the fluid or flowing medium. Thus, the blind hole-shaped design of the positioning recess and the opening in the bottom region of the positioning recess results in optimum utilization of the positioning recess and a compact design.

Es ist bevorzugt, dass die Positionierelemente steckerartig hervorragend ausgebildet sind, um mit den korrespondierenden Positionierausnehmungen gemäß einem Stecker-Buchse-Prinzip zusammenzuwirken. Durch die steckerartige Ausbildung bekommt der Monteur ein Feedback, wenn das Positionierelement in die Positionierausnehmung gelangt und weiß somit, ob Saugrohrvorrichtung und Zylinderkopf korrekt positioniert sind.It is preferred that the positioning elements are designed in a plug-like manner to cooperate with the corresponding positioning recesses according to a plug-socket principle. Due to the plug-like design, the fitter receives feedback when the positioning element enters the positioning recess and therefore knows whether the intake manifold device and the cylinder head are correctly positioned.

Weiter bevorzugt ist, dass ein erstes Positionierelement in einem Einlassbereich des Saugrohres angeordnet ist. Unter Einlassbereich ist der Mündungsbereich des Saugrohres oder des von dem Saugrohr abzweigenden Einlasskanals im Austrittsbereich zu verstehen, das heißt der Bereich, in dem Saugrohr und Zylinderkopf miteinander verbunden werden oder auch der Schnittstellenbereich. In diesem Bereich, der sich bis in das Innere des Einlasskanals erstreckt, ist das Positionierelement so ausgebildet, dass es eine ausreichende Stabilität und Stützung erfährt.It is further preferred that a first positioning element is arranged in an inlet region of the suction tube. The inlet region is to be understood as the mouth region of the suction pipe or of the inlet pipe branching off from the suction pipe in the outlet region, that is to say the region in which the intake pipe and cylinder head are connected to one another or else the interface region. In this area, which extends into the interior of the inlet channel, the positioning element is designed so that it undergoes sufficient stability and support.

Durch diese Anordnung erfolgt eine optimierte Positionierung des Saugrohres zu der Positionierausnehmung. Denn durch die Anordnung im Einlassbereich wird bei der Montage dieser Einlassbereich in dem Mündungsbereich der Positionierausnehmung ausgerichtet. Somit wird bei korrekter Anordnung dann das erste Positionierelement durch das über die Positionierausnehmung geleitete Medium oder Fluid umströmt und das Fluid gelangt durch dein Einlasskanal zu dem Saugrohr.By this arrangement, there is an optimized positioning of the suction tube to the Positionierausnehmung. Because of the arrangement in the inlet region, this inlet region is aligned in the mouth region of the positioning recess during assembly. Thus, with the correct arrangement, the first positioning element then flows around the medium or fluid conducted via the positioning recess, and the fluid passes through the inlet channel to the suction tube.

Wie beschrieben, ist es deshalb bevorzugt, dass der Einlassbereich durch einen zu dem Saugrohr führenden Einlasskanal gebildet ist. Hierdurch muss das Positionierelement nicht unmittelbar in dem Saugrohr ausgebildet sein sondern kann auch in einer Art "Nebenarm" des Saugrohres, das heißt einem abzweigenden Einlasskanal angeordnet sein, wobei hier gegebenenfalls andere Strömungsbedingungen ausgebildet sind.As described, it is therefore preferable that the inlet portion is formed by an inlet channel leading to the suction pipe. As a result, the positioning element does not have to be formed directly in the suction tube but can also be arranged in a kind of "secondary arm" of the suction tube, that is to say a branching inlet channel, whereby other flow conditions may be formed here.

Auch ist bevorzugt, dass das erste Positionierelement einen geringeren Querschnitt als eine korrespondierende erste Positionierausnehmung und/oder der Einlassbereich aufweist, damit ein Fluid an dem ersten Positionierelement vorbei in das Saugrohr strömen kann. Bevorzugt ist das Positionierelement in einer Vertiefung des Einlassbereiches angeordnet, um einen ausreichenden Freiraum zum Durchfluss des Fluids zu gewährleisten. Dabei ist der Querschnitt so auszulegen, dass einerseits der Durchfluss nicht oder nur minimal beeinträchtigt ist und andererseits die Stabilität des Positionierelements nicht beeinträchtigt ist.It is also preferred that the first positioning element has a smaller cross-section than a corresponding first positioning recess and / or the inlet region, so that a fluid can flow past the first positioning element into the suction tube. Preferably, the positioning element is arranged in a recess of the inlet region in order to ensure sufficient clearance for the passage of the fluid. In this case, the cross section is to be interpreted so that on the one hand, the flow is not or only minimally impaired and on the other hand, the stability of the positioning is not impaired.

Auch ist es bevorzugt, dass das erste Positionierelement als längliches, bevorzugt nach Art eines Schwertes, ausgebildetes Teil geformt ist. Somit weist das Positionierelement einen optimal mit der Positionierausnehmung zusammenwirkenden hervorragenden Teil auf. Durch die Ausbildung als Schwert kann bei einer geringen Querschnittsfläche eine genaue Positionierung realisiert werden, so dass ausreichen Fluid an dem Querschnitt durch die Querschnittsöffnung des Einlassbereiches fließen kann.It is also preferable for the first positioning element to be shaped as an elongated part, preferably in the manner of a sword. Thus, the positioning has an optimally cooperating with the positioning recess outstanding part. Due to the design as a sword, a precise positioning can be realized with a small cross-sectional area, so that sufficient fluid can flow at the cross-section through the cross-sectional opening of the inlet area.

Auch bevorzugt ist, dass der Querschnitt des zweiten Positionierelements ausgewählt ist aus der Gruppe umfassend runde, rechteckige, quadratische, ovale, mehreckige, kreuzförmige oder Profilquerschnitte. Grundsätzlich lässt sich jeder beliebige Querschnitt verwenden. Jedoch weisen die vorstehend aufgeführten Querschnitte eine optimale Positioniereigenschaft bei entsprechend optimiertem Herstellungsaufwand.It is also preferred that the cross section of the second positioning element is selected from the group consisting of round, rectangular, square, oval, polygonal, cross-shaped or profile cross sections. Basically any one can be Use cross section. However, the above-mentioned cross-sections have an optimum positioning property with correspondingly optimized production outlay.

Weiter bevorzugt ist, dass das zweite Positionierelement im Wesentlichen den gleichen Querschnitt wie die korrespondierende zweite Positionierausnehmung aufweist, um eine formschlüssige Steckverbindung zu realisieren. Hierdurch wird eine genau positionierbare Anordnung von Saugrohr und Zylinderkopf gewährleistet, die nur eine einzige Positionierung von Zylinderkopf und Saugrohrvorrichtung zueinander zulässt. Das zweite Positionierelement ist das nicht im Einlassbereich des Saugrohres angeordnete Positionierelement.It is further preferred that the second positioning element has substantially the same cross-section as the corresponding second positioning recess in order to realize a form-fitting plug connection. As a result, a precisely positionable arrangement of intake manifold and cylinder head is ensured, which allows only a single positioning of the cylinder head and intake manifold to each other. The second positioning element is the positioning element which is not arranged in the inlet region of the suction tube.

Fig. 1 zeigt in perspektivischer Ansicht einen erfindungsgemäßen Zylinderkopf 1 einer erfindungsgemäßen Saugrohr-Zylinderkopfanordnung. Der Zylinderkopf 1 weist seitlich einen Flansch 2 mit einer ebenen Oberfläche auf, welche zur besseren Anbindung an weitere Vorrichtungen geneigt ausgebildet ist. Von der Oberfläche verlaufen in Richtung Zylinderkopf-Inneres die Gasrückführleitungen 3 (siehe auch Fig. 3) wie auch die Positionierausnehmungen 4. Anders ausgedrückt münden die Gasrückführleitungen 3 wie auch die Positionierausnehmungen 4 in der Oberfläche des Flansches 2. Wie erwähnt weist der Flansch 2 vorliegend vier Gasrückführleitungen 3 auf. Zudem weist der Flansch 2 zwei Positionierausnehmungen 4 auf, wobei eine erste Positionierausnehmung 4afluidisch mit mindestens einer Gasrückführleitung 3 verbunden ist und die zweite Positionierausnehmung 4b nur zur Aufnahme eines entsprechenden Positionierelementes ausgebildet ist. Hierdurch kann ein Medium von der Gasrückführleitung 3 in/durch die erste Positionierausnehmung 4a strömen.Fig. 1 shows a perspective view of a cylinder head 1 according to the invention an intake manifold cylinder head assembly according to the invention. The cylinder head 1 has laterally a flange 2 with a flat surface, which is formed inclined for better connection to other devices. From the surface In the direction of the cylinder head, the gas recirculation lines 3 (see also FIG. 3) and the positioning recesses 4 run differently on. In addition, the flange 2 has two positioning recesses 4, wherein a first positioning recess 4afluidisch is connected to at least one gas return line 3 and the second positioning recess 4b is designed only for receiving a corresponding positioning element. As a result, a medium can flow from the gas return line 3 into / through the first positioning recess 4a.

Die Oberfläche des Flansches 2 ist eben ausgebildet, um so einen Anschluss für eine Saugrohrvorrichtung oder genauer mindestens ein Saugrohr zu bieten. Eine Saugrohrvorrichtung ist in Fig. 2 dargestellt.The surface of the flange 2 is flat, so as to provide a connection for a Saugrohrvorrichtung or more precisely at least one suction tube. A Saugrohrvorrichtung is shown in Fig. 2.

Fig. 2 zeigt in perspektivischer Ansicht eine Saugrohrvorrichtung 5, die vorliegend als Saugrohrverteiler mit vier Saugrohren 6 mit mindestens einem abzweigenden Einlasskanal 6a ausgebildet ist, welche jeweils zur Leitung von Medien ausgebildet sind. Die Mündungen bzw. die Mündungsquerschnitte der Saugrohrleitungen bzw. der Saugrohre 6 samt Einlasskanal 6a sind korrespondierend zu der Oberfläche des Flansches in Fig. 1 plan in einer Ebene ausgebildet, um an den ebenfalls ebenen Flansch des Zylinderkopfes gemäß Fig. 1 angeordnet zu werden. Die Saugrohrvorrichtung 5 weist zwei Positionierelemente 7 auf, ein erstes Positionierelement 7a und ein zweites Positionierelement 7b. Das zweite Positionierelement 7b ist als steckerartig über den Mündungsbereich des Einlasskanals 6a hervorragender Vorsprung oder Stift ausgebildet, der vorliegend einen kreuzförmigen Querschnitt aufweist und zur Positionierung in der zweiten Positionierausnehmung 4b ausgebildet ist.FIG. 2 shows a perspective view of a suction pipe device 5, which in the present case is designed as an intake manifold with four intake pipes 6 with at least one branching inlet duct 6a, which are each designed to conduct media. The mouths or the mouth cross-sections of the intake manifolds and the suction tubes 6 together with inlet channel 6a are formed corresponding to the surface of the flange in Fig. 1 plan in a plane to be arranged on the also flat flange of the cylinder head of FIG. The suction tube device 5 has two positioning elements 7, a first positioning element 7a and a second positioning element 7b. The second positioning element 7b is designed as a projection or pin projecting like a plug over the mouth region of the inlet channel 6a, which in the present case has a cross-shaped cross section and is designed for positioning in the second positioning recess 4b.

Das erste Positionierelement 4a ist in einer Vertiefung eines Saugrohres 6, genauer eines Teilabschnitt eines Saugrohres 6 - dem Einlasskanal 6a - ausgebildet, und ragt ebenfalls über den Mündungsbereich hervor, so dass dieses Positionierelement 7a in eine korrespondierende Positionierausnehmung, hier in die erste Positionierausnehmung gesteckt werden kann gemäß einem Stecker-Buchse-Prinzip. Das erste Positionierelement 7a weist dabei eine schwertförmige Form auf, d.h. eine etwa längliche, quaderförmige Ausbildung mit einem etwa rechteckigen Querschnitt, wobei der Querschnitt zum optimalen Durchlassen eines Fluids oder Mediums minimiert ist. Zudem weist das erste Positionierelement 7a eine in Längsrichtung verlaufende Ausnehmung auf, um einen möglichst großen Durchflussquerschnitt für ein Fluid bereitzustellen. Die Positionierelemente 7 werden bei der Montage der Saugrohrvorrichtung 5 an den Zylinderkopf in die entsprechenden Positionierausnehmungen des Zylinderkopfes gemäß Fig. 1 gesteckt. Eine zusammengebaute Saugrohr-Zylinderkopfanordnung ist in Fig. 3 dargestellt.The first positioning element 4a is formed in a recess of a suction tube 6, more precisely a section of a suction tube 6 - the inlet channel 6a - and also projects beyond the mouth region, so that this positioning element 7a are inserted into a corresponding positioning recess, here into the first positioning recess can according to a plug-socket principle. The first positioning element 7a has a sword-shaped form, i. an approximately elongated, cuboid formation with an approximately rectangular cross-section, wherein the cross-section for optimal passage of a fluid or medium is minimized. In addition, the first positioning element 7a has a recess running in the longitudinal direction in order to provide the largest possible flow cross-section for a fluid. The positioning elements 7 are inserted in the assembly of the intake manifold 5 to the cylinder head in the corresponding positioning recesses of the cylinder head of FIG. An assembled intake manifold cylinder head assembly is shown in FIG.

Fig. 3 zeigt in perspektivischer Ansicht einen Querschnitt durch eine erfindungsgemäße Saugrohr-Zylinderkopfanordnung 8. Hierbei ist der Zylinderkopf 1 mit dem Flansch an der Saugrohrvorrichtung 5 angeordnet bzw. befestigt. Der Zylinderkopf 1 weist eine Gasrückführleitung 3 auf, über die das Blow-by-Gas (Fluid) zu der Saugrohrvorrichtung 5, genauer einem Saugrohr 6 geleitet wird. Die Gasrückführleitung 3 mündet zumindest teilweise in einen Teil einer ersten Positionierausnehmung 4a. Die erste Positionierausnehmung 4a ist vorliegend als sacklochartige Vertiefung mit einem Kreisquerschnitt - als Positionierbohrung - ausgebildet. In den Bodenbereich dieser Positionierbohrung mündet zumindest ein Teil der Gasrückführleitung 5. Weiter ragt in die erste Positionierausnehmung 4a das erste Positionierelement 7a der Saugrohrvorrichtung 5.FIG. 3 shows a perspective view of a cross section through an intake manifold cylinder head assembly 8 according to the invention. Here, the cylinder head 1 is arranged or fastened to the intake manifold 5 with the flange. The cylinder head 1 has a gas return line 3, via which the blow-by gas (fluid) is led to the intake manifold 5, more precisely to a suction pipe 6. The gas return line 3 opens at least partially into a part of a first positioning recess 4a. The first positioning recess 4a is present as a blind hole-like depression with a circular cross-section - as a positioning hole - formed. At least part of the gas return line 5 opens into the bottom region of this positioning bore. Furthermore, the first positioning element 7a of the suction tube device 5 projects into the first positioning recess 4a.

In diesem montierten Zustand füllt der Querschnitt des ersten Positionierelementes 7a nicht dem gesamten Querschnitt der ersten Positionierausnehmung 4a aus. Somit kann das Blow-by-Gas in die erste Positionierausnehmung 4a an dem ersten Positionierelement 7a vorbei über den Einlasskanal 6a in das Saugrohr 6 fließen.In this mounted state, the cross section of the first positioning element 7a does not fill the entire cross section of the first positioning recess 4a. Thus, the blow-by gas into the first positioning recess 4a on the first positioning element 7a over the inlet channel 6a flow into the suction pipe 6.

Das erste Positionierelement 7a ist in einem Einlassbereich 9 eines Saugrohres 6, genauer eines Einlasskanals 6a ausgebildet. Der Einlassbereich 9 ist hier als abzweigender Kanal, Kanalabschnitt oder Einlasskanal 6a des Saugrohres 6 ausgebildet und verbindet somit das Saugrohr 6 und die Gasrückführleitung 3, so dass eine Verbindung zwischen Gasrückführleitung 3 und Saugrohr 6 realisiert ist.The first positioning element 7a is formed in an inlet region 9 of a suction tube 6, more specifically an inlet channel 6a. The inlet region 9 is here designed as a branching channel, channel section or inlet channel 6a of the suction pipe 6 and thus connects the suction pipe 6 and the gas return line 3, so that a connection between the gas return line 3 and the suction pipe 6 is realized.

Die Erfindung ist nicht beschränkt auf die vorstehend beschriebenen bevorzugten Ausführungsformen.The invention is not limited to the preferred embodiments described above.

Es sind vielmehr auch Abweichungen hiervon denkbar, welche vom Schutzbereich der nachfolgenden Ansprüche umfasst sind.Rather, deviations from this are conceivable, which are encompassed by the scope of protection of the following claims.
