Abstract
Description
Die Erfindung betrifft eine Abgasabführung für Verbrennungs kraftmaschinen, die mit zwei oder mehreren Abgasturboladern ausgerüstet sind.The invention relates to an exhaust gas discharge for combustion engines with two or more exhaust gas turbochargers are equipped.
Bekannt sind Verbrennungskraftmaschinen mit zwei oder mehreren Abgasturboladern, die eine entsprechende Anzahl von Gasabströmgehäusen aufweisen.Internal combustion engines with two or more are known Exhaust gas turbochargers that have a corresponding number of Have gas outflow housings.
Bekannt ist weiterhin eine aufgeladene Verbrennungskraftmaschine, bei der zwei Radialturbinen das Abgas in ein gemeinsames Turbinenabströmgehäuse einleiten, welches gleichzeitig als gemeinsames Verbindungselement für beide Abgasturbolader ausgebildet ist und mittels Stützelementen an einer Verbrennungs kraftmaschinenkonsole befestigt ist. Jeder der beiden Abgasturbo lader ist in fliegender Anordnung mittels Pendelstütze an einer verbrennungskraftmaschinenseitigen Auflagefläche abgestützt (DE 31 08 288 A1).A supercharged internal combustion engine is also known, in the case of the two radial turbines, the exhaust gas in a common Initiate turbine outflow housing, which at the same time as common connecting element for both exhaust gas turbochargers is formed and by means of support elements on a combustion engine console is attached. Each of the two exhaust turbo loader is in a flying arrangement by means of a pendulum support on one Supported by the internal combustion engine bearing surface (DE 31 08 288 A1).
Nachteilig ist daran, daß die Ausrichtung der Abgaseintritte der Abgasturbolader auf die das Abgas von den Zylindern zuführenden Abgasleitungen auf Grund der fixen Verbindung beider Abgas turbolader schwierig und aufwendig ist und ein Toleranzausgleich nicht möglich ist. Im Betrieb der Verbrennungskraftmaschine führt die Wärmedehnung der Abgasturbolader und des dazwischen befindlichen gemeinsamen Turbinenabströmgehäuses zur undefinierten Verschiebung der Gaseintritte am Turbinengehäuse gegenüber der Position der das Abgas von den Zylindern zuführenden Abgasleitungen.The disadvantage is that the alignment of the exhaust gas inlets Exhaust gas turbocharger on the exhaust gas from the cylinders Exhaust pipes due to the fixed connection of both exhaust gases turbocharger is difficult and complex and tolerance compensation not possible. Leads in the operation of the internal combustion engine the thermal expansion of the exhaust gas turbocharger and the one in between located common turbine outlet housing for undefined displacement of the gas inlets on the turbine housing versus the position of the exhaust from the cylinders supplying exhaust pipes.
Problem der Erfindung ist es, eine Vorrichtung zur Abgasabführung an Verbrennungskraftmaschinen mit mindestens zwei Abgas turboladern zu schaffen, die sich in ihrer größten Bemessung an den Abmessungen der Abgasturbolader orientiert, sich in ihrer Gestaltung kompakt in das äußere Erscheinungsbild der Verbrennungskraftmaschine einordnet, die die Abgasturbolader und die Abgasleitungen aufeinander auszurichten erlaubt, einen ausreichenden Toleranzausgleich zwischen den Gaseintritten an den Turbinengehäusen und den abgaszuführenden Abgasleitungen ermöglicht und die geeignet ist, im Betriebszustand der Verbrennungskraftmaschine auftretende Wärmedehnungen des Materials in Bezug auf die Turbineneintritte der Abgasturbolader lageneutral aufzunehmen.The problem of the invention is a device for exhaust gas discharge on internal combustion engines with at least two exhaust gases to create turbochargers, which in their largest dimension to the Dimensions of the exhaust gas turbocharger oriented in their Design compact in the external appearance of the Internal combustion engine that classifies the exhaust gas turbocharger and aligning the exhaust pipes allows one sufficient tolerance compensation between the gas inlets the turbine housings and the exhaust pipes to be exhausted enables and which is suitable in the operating state of the Internal combustion engine thermal expansion occurring Materials related to the turbine inlets of the exhaust gas turbochargers location neutral.
Erfindungsgemäß wird das Problem wie mit den Ansprüchen angegeben gelöst.According to the invention the problem is as with the claims specified solved.
Mit der erfindungsgemäßen Vorrichtung der Abgasabführung lassen sich Abgasturbolader und abgaszuführende Abgasleitungen paßgerecht, ohne besonderen technischen Aufwand, zueinander ausrichten, und es lassen sich Toleranzen leicht ausgleichen. Wärmedehnungen zwischen den Baugruppen sind erfindungs gemäß lageneutral kompensiert und die äußere Gestaltung der Abgasführung ordnet sich in das Gesamterscheinungsbild der Verbrennungskraftmaschine harmonisch ein.Leave with the exhaust gas discharge device according to the invention exhaust gas turbocharger and exhaust gas supply pipes fit to each other, without any special technical effort align, and tolerances can be easily compensated. Thermal expansion between the assemblies are fiction according to position neutral and the external design of the Exhaust gas routing is arranged in the overall appearance of the Internal combustion engine harmoniously.
Nachstehend wird die Erfindung an Hand eines Ausführungs beispieles näher erläutert. In der zugehörigen Zeichnung ist mitThe invention will now be described in terms of an embodiment example explained in more detail. In the accompanying drawing is with
Fig. 1 eine Anordnung des Gasabströmgehäuses an einer Verbrennungskraftmaschine in V-Form mit zwei Abgasturboladern und mit Fig. 1 shows an arrangement of the gas discharge housing on an internal combustion engine in a V-shape with two exhaust gas turbochargers and with
Fig. 2 ein Gasabströmgehäuse im Schnitt entlang der Linie A-A
gemäß Fig. 1
dargestellt. Fig. 2 is a Gasabströmgehäuse in section along the line AA of FIG. 1
shown.
Die Abgasturboladeranordnung besteht aus zwei baugleichen Abgasturboladern 1, 2 mit Radialturbine und Verdichter, die so auf verbrennungskraftmaschinenseitigen Kosolen 3 starr befestigt sind, daß ihre Achsen zueinander fluchten und die Abgaseintritte der Abgasturbolader 1, 2 auf die das Abgas von den Zylindern zuführenden Abgasleitungen ausgerichtet sind.The exhaust-gas turbocharger arrangement consists of two identical exhaust-gas turbochargers 1 , 2 with a radial turbine and compressor, which are rigidly attached to internal combustion engine-side coils 3 in such a way that their axes are aligned with one another and the exhaust-gas inlets of the exhaust-gas turbochargers 1 , 2 are aligned with the exhaust-gas lines supplying the exhaust gas from the cylinders.
Das Gasabströmgehäuse 4 ist mit dem Abgasturbolader 1 mittels Flanschverbindung 5 starr und mittels elastischer Verbindung 6 mit dem Abgasturbolader 2 verbunden.The gas discharge housing 4 is rigidly connected to the exhaust gas turbocharger 1 by means of a flange connection 5 and to the exhaust gas turbocharger 2 by means of an elastic connection 6 .
Die motorseitig gelagerte Pendelstütze 7 unterstützt das Gasabströmgehäuse 4 und läßt Wärmedehnungen zu, die im Bereich der Verbrennungskraftmaschine an den Abgasturbo ladern 1, 2 und auch am Gasabströmgehäuse 4 auftreten. The pendulum support 7 mounted on the engine supports the gas discharge housing 4 and permits thermal expansion which occurs in the area of the internal combustion engine at the exhaust gas turbo loaders 1 , 2 and also at the gas discharge housing 4 .
Die Prallplattendiffusoren 8, 9 sind mit gemeinsamer Prallplatte 10 als gegossene Ausführung des Gasabströmgehäuses 4 ausgebildet. The baffle plate diffusers 8 , 9 are formed with a common baffle plate 10 as a cast version of the gas outflow housing 4 .
