Es ist weiter aus der japanischen Patentveröffentlichung 2-37104 ein gattungsgemäßes Saugrohrmodul bekannt, bei dem in der Mitte zwischen gegenüberliegenden Saugrohranlagen zwei miteinander kommunizierende Rückführkanäle vorgesehen sind, deren jeweils eines Ende an den inneren Umfang eines Saugrohrs grenzt und deren anderes Ende in eine Sammelkammer führt, in welche die Durchblasgase eingeleitet werden. Diese Rückführeinrichtung ist insoweit nachteilig, als eine Vielzahl von Anschlüssen für die Rückführung der Durchblasgase erforderlich sind, wodurch auch die Störanfälligkeit des Systems erhöht wird.It is further from Japanese Patent Publication 2-37104 a generic intake manifold module known to be in the middle between opposed intake manifolds two mutually communicating return channels are provided, each of which one end adjoins the inner circumference of a suction tube and its another end leads into a collection chamber, in which the blow-by gases be initiated. This return device is disadvantageous in that a plurality of connections for the return of the Blow-by gases are required, whereby the susceptibility to failure of the system increases becomes.
Aus
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Saugrohrmodul der eingangs beschriebenen Art so zu verbessern, daß die Rückführeinrichtung möglichst platzsparend untergebracht und, ohne aufwendige Montagearbeiten zu erfordern, bestimmungsgemäß angeordnet werden kann.Of the The present invention is based on the object, a suction tube module to improve the type described above so that the return device preferably space-saving housed and, without complex assembly work to require, arranged as intended can be.
Diese Aufgabe wird bei einem gattungsgemäßen Saugrohrmodul erfindungsgemäß dadurch gelöst, daß das Saugrohrmodul ein vorzugsweise aus Kunststoff bestehendes Gehäuse aus zwei Gehäuseschalen aufweist und die Rückführeinrichtung in einem von den beiden Gehäuseschalen gebildeten Totraum des Saugrohrmoduls untergebracht ist.These The object is achieved in a generic Saugrohrmodul according to the invention that the Saugrohrmodul a preferably made of plastic housing of two housing shells has and the return device in one of the two housing shells formed dead space of the intake manifold is housed.
Bei dem erfindungsgemäßen Saugrohrmodul ist die Rückführeinrichtung daher platzsparend untergebracht. Der Totraum verläuft vorzugsweise im wesentlichen senkrecht zur Strömungsrichtung der Saugrohranlage und gestattet daher eine gleichmäßige Einleitung der Kurbelgehäusegase. Bei einer besonders vorteilhaften Ausführungsform der Erfindung umgibt die Saugrohranlage den Totraum etwa torusförmig.at the intake manifold module according to the invention is the return device therefore accommodated space-saving. The dead space preferably runs substantially perpendicular to the flow direction of the intake manifold and therefore allows a uniform introduction the crankcase gases. In a particularly advantageous embodiment of the invention surrounds the intake manifold the dead space approximately torus-shaped.
Die Rückführeinrichtung könnte ansich von dem Totraum selbst gebildet sein; sie umfaßt aber vorzugsweise eine Verteilerleiste mit einer Anschlußöffnung zum Einströmen und einer Mündungsöffnung zum Ausströmen von Kurbelgehäusegasen.The Return means could to be formed by the dead space itself; but it preferably includes a distribution strip with a connection opening for the inflow and a mouth opening to the escape of crankcase gases.
Die Rückführeinrichtung oder Verteilerleiste kann besonders kostengünstig aus zwei miteinander verbindbaren Kunststoffhalbschalen gebildet sein, die in ansich beliebiger Weise, vorzugsweise über eine Außenschweißnaht miteinander verbunden werden.The Return means or distribution bar can be particularly cost-effective from two interconnected Plastic half-shells are formed, which in ansich in any way, preferably via a External weld together get connected.
Im Hinblick auf eine einfache und schnelle Montage ist die Rückführeinrichtung bzw. die Verteilerleiste formschlüssig in dem Totraum angeordnet und dichtend mit der Saugrohranlage verbunden.in the In view of a simple and quick installation is the return device or the distribution bar arranged positively in the dead space and sealingly connected to the intake manifold.
Bei einer besonders bevorzugten Ausführungsform der Erfindung weist die Rückführeinrichtung einen der Einströmöffnung zugewandten Sammelraum und einen mit diesem strömungsmäßig kommunizierenden Verteilerraum auf, welch letzterer in die Saugrohranlage mündet. Der Sammelraum und der Verteilerraum erstrecken sich dabei vorzugsweise über die gesamte Länge der Rückführeinrichtung, so daß eine gleichmäßige Einleitung von Kurbelgehäusegasen in die Saugrohranlage erreicht werden kann. Desweiteren wird vorgeschlagen, den Sammelraum und den Verteilerraum über wenigstens eine Drosselöffnung miteinander zu verbinden und desweiteren den Verteilerraum durch wenigstens eine Zwischenwand zu unterteilen. Es läßt sich dann durch die Anzahl und die Querschnitte der Drosselbohrungen einerseits und/oder die Lage der wenigstens einen Zwischenwand in Bezug auf die Mündungsöffnungen des Verteilerraums eine Gleichverteilung der Gase auf die einzelnen Zylinder erreichen.at a particularly preferred embodiment The invention comprises the return device one of the inlet opening facing Collecting space and a communicating with this flow distribution space on, which latter flows into the intake manifold. The collection room and the Distributor space preferably extend over the whole length the return device, so that one even introduction of crankcase gases can be achieved in the intake manifold. Furthermore, it is proposed the collecting space and the distribution space via at least one throttle opening with each other to connect and further the distribution space by at least one Divide partition wall. It can then be determined by the number and the cross sections of the throttle bores on the one hand and / or the Location of the at least one intermediate wall with respect to the mouth openings the distribution space an equal distribution of gases to the individual Reach cylinder.
Der Einströmöffnung der Rückführeinrichtung wird vorzugsweise ein Ölabscheider vorgeordnet, mit dem sich die Öldunstmenge in den zurückzuführenden Gasen steuern läßt.Of the Inflow opening of the Return means is preferably an oil separator upstream, with which the oil mist quantity in the attributed Controlling gases.
Es wird desweiteren vorgeschlagen, das Saugrohrmodul bzw. die Rückführeinrichtung so auszubilden, daß durch Verschweißen, insbesondere durch Vibrationsschweißen, der beiden Gehäuseschalen die Rückführeinrichtung in dem von den beiden Gehäuseschalen gebildeten Totraum ortsfest positioniert wird.It is further proposed, the intake manifold module or the return device in such a way that through welding, in particular by vibration welding, the two housing shells the return device in the of the two housing shells formed dead space is positioned stationary.
Insbesondere bei etwa torusförmig ausgebildetem Saugrohrmodul kann der Totraum von quer oder schräg zur Strömungsrichtung der Verbrennungsluft innerhalb der Saugrohranlage verlaufenden Stegbereichen begrenzt werden. Die Stegbereiche, welche die beiden Gehäuseschalen gegeneinander abstützen, verlaufen vorzugsweise im wesentlichen parallel zueinander und bilden eine Einsetzöffnung für die Rückführeinrichtung. Die Rückführeinrichtung braucht dann einfach in der Einsetzöffnung einer der Gehäuseschalen positioniert zu werden und anschließend wird die andere Gehäuseschale aufgesetzt und dabei die Rückführeinrichtung fixiert. Die Stegbereiche sind vorzugsweise einstückig mit der im montierten Zustand des Saugrohrmoduls dem Zylinderkopf zugewandten Gehäuseschale ausgebildet oder dieser Schale angefügt. Die Rückführeinrichtung kann dann in den von den stegartigen Bereichen definierten Totraum eingesetzt werden, so daß sie in die Saugrohranlage mündet, wobei etwa an der Rückführeinrichtung angeordnete Anschlußstutzen in entsprechende Öffnungen in der Saugrohrwandung eingesteckt werden.Especially at about torus-shaped trained suction tube module, the dead space of transverse or oblique to the flow direction of the Combustion air within the intake manifold extending web areas be limited. The web areas, which are the two housing shells support against each other, preferably run substantially parallel to each other and form an insertion opening for the Recirculation device. The return device then simply needs in the insertion of one of the housing shells to be positioned and then the other housing shell is placed and at the same time the return device fixed. The land areas are preferably integral with the in the mounted state of the intake manifold module facing the cylinder head shell formed or added to this dish. The return device can then be in the dead space defined by the web-like areas used so they flows into the intake manifold, where about at the return device arranged connecting piece in corresponding openings be inserted in the Saugrohrwandung.
Hiernach können die Gehäuseschalen an den freien Enden der Stegbereiche miteinander verschweißt werden, so daß auch in diesem Abschnitt eine dichtende Verbindung der beiden Gehäuseschalen gewährleistet ist.hereafter can the housing shells be welded together at the free ends of the web areas, so that too in this section a sealing connection of the two housing shells guaranteed is.
Die freien Enden der Stegbereiche und die korrespondierenden Schweißbereiche der Gehäuseschale werden dann vorzugsweise so ausgebildet, daß ein Schweißaustrieb in den Totraum gelangt.The free ends of the web areas and the corresponding welding areas the housing shell are then preferably formed so that a Schweißaustrieb gets into the dead space.
