Abstract
Description
Die Erfindung bezieht sich auf eine Abgassammelleitung für eine mehrzylindrige Brennkraftmaschine mit Abgasstutzen zwischen der Abgassammelleitung und den Gaswechselkanälen, vorzugsweise im Zylinderkopf einer Hubkolbenbrennkraftmaschine, wobei die Abgassammelleitung in zumindest zwei Abgasleitungen unterteilt ist, die mittels eines ein Wellrohr aufweisenden Kompensators miteinander verbunden sind.The The invention relates to an exhaust manifold for a multi-cylinder Internal combustion engine with exhaust pipe between the exhaust manifold and the gas exchange channels, preferably in the cylinder head of a reciprocating internal combustion engine, wherein the exhaust manifold is divided into at least two exhaust pipes is, by means of a bellows having a compensator with each other are connected.
Eine
derartige Abgassammelleitung ist aus der
Darüber hinaus stellen die Wellrohre eine Beeinträchtigung der Strömung der Abgase in dem Übergang zwischen den Abgasleitungen dar, die ebenfalls unerwünscht ist.Furthermore make the corrugated pipes affect the flow of the Exhaust gases in the transition between the exhaust pipes, which is also undesirable.
Aufgabe der Erfindung ist es, eine gattungsgemäße Abgassammelleitung so zu verbessern, dass ihre Lebensdauer wesentlich verbes sert wird, ohne dass dadurch die Dehnungsmöglichkeiten der Abgasleitungen untereinander verringert werden. Des Weiteren soll die Verbesserung mit einfachen Mitteln erfolgen.task The invention is to a generic exhaust manifold so too improve their life significantly improves without that thereby the stretching possibilities the exhaust pipes are mutually reduced. Furthermore the improvement should be done with simple means.
Die Aufgabe der Erfindung wird dadurch gelöst, dass zusätzlich zu dem jeweiligen Kompensator, vorzugsweise innerhalb desselben, zwischen den Abgasleitungen eine Abschirmeinrichtung vorgesehen ist.The The object of the invention is achieved in that in addition to the respective compensator, preferably within the same between the exhaust pipes a shielding device is provided.
Die Abschirmeinrichtung kann beliebig ausgeführt sein. Sie dient dazu, zwischen den Abgasleitungen eine eigenständige Verbindung herzustellen, die auch einen möglichst glatten Übergang zwischen den Abgasleitungen sicherstellt.The Shielding can be performed arbitrarily. It serves to between the exhaust pipes an independent Make connection, which is also the smoothest possible transition ensures between the exhaust pipes.
In einer vorteilhaften Ausgestaltung der Erfindung ist die Abschirmeinrichtung als Rohrstück ausgebildet, das Endabschnitte beider Abgasleitungen umgreift oder innerhalb beider Abgasleitungen eingesetzt ist. Dadurch wird zwischen den Abgasleitungen eine eigene Wandung zur Verfügung gestellt, die die Wärme und Drücke der Abgase von dem Kompensator bzw. dem Wellrohr des Kompensators abhält. Dadurch wird sowohl die Temperaturbeeinträchtigung des Wellrohres als auch der Druck auf das Wellrohr beispielsweise dann, wenn an die Abgassammelleitung die Turbine eines Turboladers angeschlossen ist, reduziert.In An advantageous embodiment of the invention is the shielding designed as a piece of pipe, the end portions of both exhaust pipes encompasses or within both exhaust pipes is used. This will between the Exhaust pipes provided their own wall covering the heat and pressures the exhaust gases from the compensator or the corrugated tube of the compensator stops. Thereby is both the temperature degradation of the corrugated pipe as also the pressure on the corrugated pipe, for example, if at the Exhaust manifold, the turbine of a turbocharger is connected, reduced.
Die Rohrstücke können an beiden Abgasleitungen verschiebbar geführt sein. Es ist aber auch möglich, dass die Rohrstücke an einer Abgasleitung festgelegt und an der anderen Abgasleitung verschiebbar geführt sind.The pipe pieces can be slidably guided on both exhaust pipes. But it is also possible that the pipe pieces fixed to one exhaust pipe and to the other exhaust pipe slidably guided are.
Um den Übergang zwischen den Abgasleitungen möglichst glatt und strömungsgünstig zu halten, sind dann, wenn die Rohrstücke die Abgasleitungen umgreifen, die Endabschnitte der Abgasleitungen in ihren Abmessungen reduziert, so dass die Rohrstücke näher an die Innenwand der Abgasleitungen gelangen, oder die Abgasleitungen weisen erweiterte Abmessungen auf, wenn die Rohrstücke innerhalb der Abgasleitungen eingesetzt sind.Around the transition between the exhaust pipes as possible smooth and streamlined too are, when the pipe sections surround the exhaust pipes, reduces the end sections of the exhaust pipes in their dimensions, so that the pipe pieces closer to enter the inner wall of the exhaust pipes, or the exhaust pipes have extended dimensions if the pipe sections are inside the exhaust pipes are used.
Die Rohrstücke können in beiden Versionen Ringwulste aufweisen, die im einen Fall auf ihrem Außenumfang und im anderen Fall auf ihrem Innenumfang angeordnet sind.The pipe pieces can in both versions have annular beads, which in one case its outer circumference and in the other case are arranged on its inner circumference.
In einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, dass die Abschirmeinrichtung zwei Rohrstücke aufweist, dass jedes Rohrstück einen Endabschnitt einer Abgasleitung umgreift und dort festgelegt ist und dass ein Rohrstück einen mit einer reduzierten Außenabmessung versehenen Endbereich aufweist, der im zweiten Rohrstück verschiebbar eingefügt ist. Dabei kann das zweite Rohrstück ohne Änderung seiner Abmessungen ausgeführt sein oder aber auch in seinem dem ersten Rohrstück zugewandten Endbereich eine erweiterte Innenabmessung haben.In Another embodiment of the invention proposes that the shielding device comprises two pieces of pipe, that each piece of pipe a End portion of an exhaust pipe surrounds and fixed there and that a piece of pipe one with a reduced outside dimension having provided end portion, which is displaceable in the second tube piece added is. In this case, the second piece of pipe without changing its dimensions accomplished be or even in his the first piece of pipe facing end a have extended inside dimension.
Weiterhin wird als Alternativlösung vorgeschlagen, dass ein der einander zugewandten Endabschnitte der Abgasleitungen eine reduzierte Außenabmessung aufweist, der im zweiten Endabschnitt, der vorzugsweise eine erweiterte Innenabmessung hat, verschiebbar eingefügt ist.Farther is considered an alternative solution proposed that one of the mutually facing end portions of the Exhaust pipes has a reduced outer dimension, the in the second end portion, which preferably has an expanded inner dimension has inserted, displaceable is.
In vorteilhafter Weise weisen die Kompensatoren ringförmige Endstücke auf, die die Abgasleitungen umgreifen. Da auf die Kompensatoren eine reduzierte Druck- und Temperaturbelastung einwirkt, brauchen diese nicht mit dem beim Stand der Technik vorgesehenen Aufwand an den Abgasleitungen befestigt werden.In Advantageously, the compensators have annular end pieces, which surround the exhaust pipes. There on the compensators one reduced pressure and temperature load, they need this not with the foreseen in the prior art effort on the Exhaust pipes are attached.
Die Abgasleitungen haben im Bereich der Endstücke reduzierte Abmessungen, so dass die ringförmigen Endstücke sich ohne Absatz an die Abgasleitungen anschließen.The exhaust pipes have reduced dimensions in the area of the end pieces, so that the annular end pieces connect without paragraph to the exhaust pipes.
Zwischen den ringförmigen Endstücken der Kompensatoren und der Abgasleitungen bzw. deren reduzierten Abmessungen können zur besseren Führung und Abdichtung Dichtbänder angeordnet sein.Between the annular tails the compensators and the exhaust pipes or their reduced Dimensions can for better guidance and sealing sealing tapes be arranged.
