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.

Each intake pipe is made up of three parts, a first intake manifold part on the cylinder head side and a second intake pipe part, which is connected to the air collector is, are each longitudinally divided and by a middle one The intake manifold part can be complemented. This middle one The intake manifold part is interchangeable, with one change the intake manifold geometry of this part different overall lengths of the suction pipe can be adjusted. hereby is an intake manifold length adjustment with relatively simple measures while maintaining the air collector geometry to different Internal combustion engines possible.
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 lies Problem based on creating a compact intake system, which with little effort to different internal combustion engines can be customized.
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 the claim 1 solved. The subclaims provide useful training on.
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 können verschiedene Saugrohrlängen bzw. Saugrohrvolumina realisiert werden, 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 intake pipe is longitudinally divided, so that at least two along a longitudinal pipe plane Intake pipe parts are formed, the air collector with a the intake manifold parts a coherent, one-piece base part forms and the other intake manifold part as an interchangeable part is executed, which forms a wall shell of the air collector. The base part can be identical for different engine variants be made, whereas the interchangeable part to the respective Requirements especially with regard to the motor size and - performance data can be adjusted. Because of the one-piece Execution of a suction pipe part with a wall section of the Air collector is a particularly compact size. suction pipe and wall part of the air collector can in particular also be formed in one piece and for example by injection molding manufactured as a common plastic component become. By using an interchangeable intake manifold part with modified geometry, different intake manifold lengths or Intake manifold volumes can be realized that match the respective internal combustion engine are adjusted. The remaining intake manifold parts and the remaining wall sections of the air collector - the base part - can are retained unchanged, which on the one hand means the variety of parts and thus the tool costs are reduced and on the other hand also the design and size of the intake system in the Mainly be 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 intake manifold part forming the interchangeable part can for example by welding firmly and indissolubly to the Base part to be connected. However, there may also be one 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 development, a pipe end piece protrudes of the interchangeable intake manifold part into the interior of the air collector. The length of this protruding intake manifold, which is part of the interchangeable intake manifold part forms, determines the total length of the intake manifold. Therefore it is generally sufficient to use different intake manifold parts long pipe end piece to form the total length of the To vary intake manifold and to different internal combustion engines adapt. The pipe end fitting protruding into the air collector requires no additional space, which makes it special 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.A radially projecting stop can be provided on the pipe end connector be in the installed position on the inside wall of the Air collector supports, which on the one hand facilitates assembly is given and on the other hand an airtight seal between the interchangeable intake manifold part 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.The exchangeable intake manifold part expediently forms an upper shell of the suction pipe and the wall part connected to it a cover shell of the air collector. But it is also possible to use the lower shell of the suction tube interchangeable, with in In this case, only one wall side of the air collector is expediently in one piece with the lower shell. Basically it is but also possible to combine the air collector as a box with the Form the lower shell and execute it as an interchangeable component.
