Description

Die Erfindung bezieht sich auf ein Ansaugsystem für eine Brennkraftmaschine nach dem Oberbegriff des Anspruches 1.The invention relates to an intake system for an internal combustion engine according to the preamble of claim 1.

Aus der Druckschrift DE 199 44 855 A1 ist eine Ansaugeinrichtung für eine Brennkraftmaschine bekannt, welche mehrere Ansaugrohre, die jeweils einem Zylinder der Brennkraftmaschine zugeordnet sind, sowie einen gemeinsamen Sammelraum für die Ansaugrohre umfasst, über den die Ansaugrohre mit Verbrennungsluft versorgt werden. Jedes Ansaugrohr ist dreiteilig aufgebaut, wobei ein erstes Saugrohrteil auf der Zylinderkopfseite und ein zweites Saugrohrteil, welches an den Luftsammler angeschlossen ist, jeweils längsgeteilt sind und von einem mittleren Saugrohrteil komplementär ergänzt werden. Dieses mittlere Saugrohrteil ist austauschbar ausgeführt, wobei durch eine Änderung der Saugrohrgeometrie dieses Teiles unterschiedliche Gesamtlängen des Saugrohres eingestellt werden können. Hierdurch ist mit verhältnismäßig einfachen Maßnahmen eine Saugrohrlängenanpassung unter Beibehaltung der Luftsammlergeometrie an unterschiedliche Brennkraftmaschinen möglich.From the publication DE 199 44 855 A1 an intake device for an internal combustion engine is known, which comprises a plurality of intake pipes, which are each associated with a cylinder of the internal combustion engine, and a common collecting space for the intake pipes, via which the intake pipes are supplied with combustion air. Each intake pipe is constructed in three parts, wherein a first intake manifold on the cylinder head side and a second intake manifold, which is connected to the air collector, are each longitudinally divided and complemented by a central intake manifold complementary. This middle Saugrohrteil is designed to be interchangeable, which can be adjusted by changing the Saugrohrgeometrie this part different total lengths of the suction pipe. As a result, it is possible with relatively simple measures a Saugrohrlängenanpassung while maintaining the Luftsammlergeometrie to different internal combustion engines.

Von diesem Stand der Technik ausgehend liegt der Erfindung das Problem zugrunde, ein kompaktes Ansaugsystem zu schaffen, welches mit geringem Aufwand an unterschiedliche Brennkraftmaschinen angepasst werden kann.Based on this prior art, the invention is based on the problem to provide a compact intake system, which can be adapted with little effort to different internal combustion engines.

Dieses Problem wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This problem is solved according to the invention with the features of claim 1. The dependent claims indicate expedient developments.

Bei dem erfindungsgemäßen Ansaugsystem ist das Saugrohr längsgeteilt, so dass entlang einer Rohrlängsebene zumindest zwei Saugrohrteile gebildet sind, wobei der Luftsammler mit einem der Saugrohrteile ein zusammenhängendes, einteiliges Basisteil bildet und das andere Saugrohrteil als einsetzbares Wechselteil ausgeführt ist, das eine Wandschale des Luftsammlers bildet. Das Basisteil kann für verschiedene Motorvarianten identisch gefertigt sein, wohingegen das Wechselteil an die jeweiligen Anforderungen insbesondere im Hinblick auf die Motorgröße und - leistungsdaten angepasst werden kann. Aufgrund der einteiligen Ausführung eines Saugrohrteiles mit einem Wandabschnitt des Luftsammlers wird ein besonders kompaktes Baumaß erzielt. Saugrohrteil und Wandteil des Luftsammlers können insbesondere auch einstückig ausgebildet sein und beispielsweise im Spritzgussverfahren als ein gemeinsames Kunststoffbauteil hergestellt werden. Durch Verwenden eines austauschbaren Saugrohrteiles mit modifizierter Geometrie werden verschiedene Saugrohrlängen bzw. Saugrohrvolumina realisiert, die an die jeweilige Brennkraftmaschine angepasst sind. Die übrigen Saugrohrteile und die übrigen Wandabschnitte des Luftsammlers - das Basisteil - können unverändert beibehalten werden, wodurch einerseits die Teilevielfalt und damit auch die Werkzeugkosten reduziert und andererseits auch die Bauform und Baugröße des Ansaugsystems im Wesentlichen beibehalten werden.In the intake system according to the invention, the suction pipe is longitudinally divided, so that along a tube longitudinal plane at least two Saugrohrteile are formed, the air collector with one of the Saugrohrteile a contiguous, one-piece base part and the other Saugrohrteil is designed as a usable removable part, which forms a wall shell of the air collector. The base part can be manufactured identically for different engine variants, whereas the interchangeable part can be adapted to the respective requirements, in particular with regard to the engine size and performance data. Due to the one-piece design of a Saugrohrteiles with a wall portion of the air collector a particularly compact dimensions is achieved. Suction tube part and wall part of the air collector may in particular also be integrally formed and produced for example by injection molding as a common plastic component. By using a replaceable intake manifold part with modified geometry different intake manifold lengths or intake manifold volumes are realized, which are adapted to the respective internal combustion engine. The remaining intake manifold and the other wall sections of the air collector - the base - can be kept unchanged, which on the one hand reduces the variety of parts and thus the tooling costs and on the other hand, the design and size of the intake system are substantially maintained.

Bei der Montage kann das das Wechselteil bildende Saugrohrteil beispielsweise durch Verschweißen fest und unauflösbar mit dem Basisteil verbunden werden. Gegebenenfalls kommt aber auch eine lösbare Verbindung in Betracht.During assembly, the alternating part forming the suction tube part, for example, by welding firmly and non-detachably connected to the base part. Optionally, however, also comes a detachable connection into consideration.

In einer besonders vorteilhaften Weiterbildung ragt ein Rohrendstutzen des austauschbaren Saugrohrteiles in den Innenraum des Luftsammlers ein. Die Länge dieses einragenden Saugrohrstutzens, welcher einen Bestandteil des austauschbaren Saugrohrteiles bildet, bestimmt die Gesamtlänge des Saugrohres. Daher reicht es grundsätzlich aus, Saugrohrteile mit unterschiedlich langen Rohrendstutzen auszubilden, um die Gesamtlänge des Saugrohres zu variieren und an unterschiedliche Brennkraftmaschinen anzupassen. Der in den Luftsammler einragende Rohrendstutzen benötigt keinen zusätzlichen Bauraum, wodurch eine besonders kompakte Ausführung zu erzielen ist.In a particularly advantageous embodiment, a pipe end of the exchangeable intake manifold protrudes into the interior of the air collector. The length of this projecting Saugrohrstutzens, which forms part of the exchangeable Saugrohrteiles, determines the total length of the suction pipe. Therefore, it is basically sufficient to design intake manifold parts with differently sized pipe end stubs in order to vary the overall length of the intake manifold and to adapt it to different internal combustion engines. The protruding into the air collector pipe end requires no additional space, which is a particularly compact design can be achieved.

Am Rohrendstutzen kann ein radial überstehender Anschlag vorgesehen sein, welcher sich in Einbaulage an der Innenwand des Luftsammlers abstützt, wodurch einerseits eine Montageerleichterung gegeben ist und andererseits ein luftdichter Abschluss zwischen dem austauschbaren Saugrohrteil und dem Luftsammler unterstützt wird. Zwischen dem Anschlag und der Innenwand des Luftsammlers kann ein Dichtungselement angeordnet werden.At the pipe end a radially projecting stop can be provided, which is supported in the installed position on the inner wall of the air collector, whereby on the one hand a mounting relief is given and on the other hand, an airtight seal between the replaceable intake manifold and the air collector is supported. Between the stop and the inner wall of the air collector, a sealing element can be arranged.

Zweckmäßig bildet das austauschbare Saugrohrteil eine Oberschale des Saugrohres und das damit verbundene Wandteil eine Deckelschale des Luftsammlers. Es ist aber auch möglich, die Unterschale des Saugrohres austauschbar auszubilden, wobei in diesem Fall zweckmäßig nur eine Wandseite des Luftsammlers einteilig mit der Unterschale ausgeführt ist. Grundsätzlich ist es aber auch möglich, den Luftsammler als Kasten einteilig mit der Unterschale auszubilden und als austauschbares Bauteil auszuführen.Suitably, the exchangeable intake manifold forms an upper shell of the suction pipe and the wall part connected thereto a cover shell of the air collector. But it is also possible to form the lower shell of the suction tube replaceable, in which case expediently only one wall side of the air collector is designed in one piece with the lower shell. Basically, it is also possible to form the air collector as a box in one piece with the lower shell and run as a replaceable component.

Weitere Vorteile und zweckmäßige Ausführungen sind den weiteren Ansprüchen, der Figurenbeschreibung und den Zeichnungen zu entnehmen. Es zeigen:

In den Figuren sind gleiche Bauteile mit gleichen Bezugszeichen versehen.In the figures, the same components are provided with the same reference numerals.

Das in Fig. 1 dargestellte Ansaugsystem 1 für eine Brennkraftmaschine umfasst einen Luftsammler 2 sowie mehrere, vom Luftsammler 2 abzweigende Saugrohre 3, von denen in Fig. 1 jedoch nur eines im Schnitt dargestellt ist, wobei die Saugrohre zu den Zylindereinlässen der Brennkraftmaschine geführt und über einen Flansch 10 am Zylinderkopf der Brennkraftmaschine zu befestigen sind. Sowohl der Luftsammler 2 als auch jedes Saugrohr 3 sind zweiteilig ausgebildet. Jedes Saugrohr 3 ist längsgeteilt und besteht aus zwei Saugrohrteilen 4 und 5, von denen das obere Saugrohrteil 4 eine austauschbare Oberschale und das untere Saugrohrteil 5 eine fest stehende Unterschale bildet. Der Luftsammler 2 besteht aus einem Kasten 6 und einer austauschbaren Deckelschale 7. Die Deckelschale 7 bildet mit dem oberen, austauschbaren bzw. einsetzbaren Saugrohrteil 4 ein gemeinsames, einteiliges Bauteil. Der Kasten 6 des Luftsammlers 2 bildet mit dem unteren Saugrohrteil 5 - der Unterschale des Saugrohres 3 - ebenfalls ein einteiliges Bauteil. Luftsammler und Saugrohr sind zweckmäßig als Kunststoff-Spritzgussbauteil hergestellt, wobei die Deckelschale 7 des Luftsammlers 2 mit dem oberen Saugrohrteil 4 ein gemeinsames Spritzgussteil und in entsprechender Weise der Kasten 6 des Luftsammlers mit dem unteren Saugrohrteil 5 ein gemeinsames Spritzgussteil bildet.This in Fig. 1 illustrated intake system 1 for an internal combustion engine comprises an air collector 2 and a plurality of branched off from the air collector 2 suction pipes 3, of which in Fig. 1 however, only one is shown in section, wherein the suction pipes are guided to the cylinder inlets of the internal combustion engine and to be fastened via a flange 10 on the cylinder head of the internal combustion engine. Both the air collector 2 and each suction tube 3 are formed in two parts. Each suction pipe 3 is longitudinally divided and consists of two Saugrohrteilen 4 and 5, of which the upper Saugrohrteil 4 a replaceable upper shell and the lower Saugrohrteil 5 forms a fixed lower shell. The air collector 2 consists of a box 6 and a replaceable lid shell 7. The lid shell 7 forms with the upper, interchangeable or insertable Saugrohrteil 4 a common, one-piece component. The box 6 of the air collector 2 forms with the lower intake manifold 5 - the lower shell of the suction tube 3 - also a one-piece component. Air collector and suction pipe are useful as a plastic injection molded component manufactured, wherein the cover shell 7 of the air collector 2 forms a common injection molded part with the upper Saugrohrteil 4 a common injection molded part and in a corresponding manner the box 6 of the air collector with the lower Saugrohrteil 5 a common injection molded part.

Die Deckelschale 7 sowie das mit der Deckelschale zusammenhängende obere Saugrohrteil 4 sind lösbar und austauschbar ausgeführt und können über Befestigungseinrichtungen 11 bzw. 12 mit dem Kasten 6 bzw. dem unteren Saugrohrteil 5 verbunden werden. Oberes und unteres Saugrohrteil können auch unlösbar miteinander verbunden werden, beispielsweise durch Verschweißen.The cover shell 7 as well as the upper intake manifold part 4, which is connected to the cover shell, are detachable and exchangeable and can be connected via fasteners 11 and 12 respectively to the housing 6 and the lower intake manifold 5. Upper and lower intake manifold can also be permanently connected to each other, for example by welding.

Einteilig mit dem oberen, austauschbaren Saugrohrteil 4 ist ein Rohrendstutzen 8 ausgebildet, welcher in Zusammenbauposition in den Innenraum des Luftsammlers 2 einragt und sich zu seiner offenen Seite hin trompetenartig erweitert. Dieser Rohrendstutzen 8 ist als in Umfangsrichtung durchgehend umlaufendes Rohr ausgeführt, wohingegen der außerhalb des Luftsammlers liegende Abschnitt des oberen Saugrohrteiles 4 als Halbschale ausgeführt ist, die in Zusammenbaulage vom unteren Saugrohrteil 5 komplementär zu einem gemeinsamen Saugrohr ergänzt wird.Integral with the upper, interchangeable Saugrohrteil 4 is a pipe end 8 is formed, which protrudes into the assembly position in the interior of the air collector 2 and widens trumpet-like towards its open side. This pipe end 8 is designed as circumferentially continuous circulating tube, whereas the portion of the upper Saugrohrteiles 4 located outside the air collector is designed as a half-shell, which is complemented in the assembly position of the lower intake manifold 5 complementary to a common intake manifold.

Wie dem Vergleich zwischen den Fig. 1 und 2 zu entnehmen, kann durch eine Variation der Länge des Rohrendstutzens 8 die Gesamtlänge des Saugrohres 3 variiert werden, wobei die sonstige Geometrie des Ansaugsystems unverändert beibehalten werden kann. Gegebenenfalls kann es aber auch zweckmäßig sein, alternativ oder zusätzlich die Geometrie der Deckelschale 7 des Luftsammlers 2 zu variieren, um ebenfalls eine Änderung der Saugrohrlänge und/oder des Luftvolumens in dem Luftsammler und dem Saugrohr zu erreichen; auch dieser Fall ist in den Figuren dargestellt, in denen sich die Deckelschalengeometrie unterscheidet.Like the comparison between the Fig. 1 and 2 can be varied by varying the length of the pipe end 8, the total length of the suction pipe 3, wherein the other geometry of the intake system can be maintained unchanged. Optionally, it may also be expedient, alternatively or additionally, to vary the geometry of the cover shell 7 of the air collector 2 in order to likewise achieve a change in the suction tube length and / or the air volume in the air collector and the suction tube; This case is also shown in the figures, in which the cover shell geometry differs.

Am Rohrendstutzen 8 ist ein einteiliger, radial über die Außenwand des Rohrendstutzens überstehender Anschlag 9 ausgebildet, welcher in Einbaulage an der Innenwand des Kastens des Luftsammlers 2 anliegt. Der Anschlag 9 stellt eine Montageerleichterung dar.At the pipe end 8 a one-piece, radially projecting beyond the outer wall of the pipe end nozzle stop 9 is formed, which rests in the installed position on the inner wall of the box of the air collector 2. The stop 9 represents a mounting relief.
