Description

Hohes zweiflutiges Guss-Abgassammelrohr mit separierten Kanälen  Tall double-flow cast exhaust manifold with separate channels
B E S C H R E I B U N G DESCRIPTION
Die Erfindung bezieht sich auf ein zweiflutiges Sechszylinder-Guss-Abgas- sammelrohr mit separierten Kanälen. The invention relates to a double-flow cast six-cylinder exhaust gas collection pipe with separate channels.
Im Landtechnikbereich werden Motoren gefordert, welche eine besonders schmale Einbaugröße vorweisen. Die Abgasturbolader werden aus diesem Grund von der Position seitlich neben dem Motor auf eine Position ober halb des Motors verschoben. In the agricultural technology sector, motors are required that have a particularly narrow installation size. For this reason, the exhaust gas turbochargers are moved from the position next to the engine to a position above the engine.
Versuche, die Abgasübergabe zur Motoroberseite aus einem einzigen Gussbauteil zu realisieren, zeigen diverse Schwierigkeiten auf, insbesondere bei erforderlichen zweiflutigen Abgasleitungen, welche durch die hohe ATL-Position dann einen besonders langen dünnen und zweiflutigen Hals haben. Es entsteht ein Zielkonflikt zwischen der aufgrund der hohen dynamischen Belastung erforderlichen Verrippung (um den Turbolader schwin- gungstechnisch abzusichern) und den thermomechanischen Eigenspan nungen. Um diesen Zielkonflikt zu umgehen, wurde die Abgasverrohrung dorthin mit zusätzlichen, z. B. auf der Ladeluftleitung oder dem Zylinderkopf gelagerten, Konsolen realisiert. Neben den höheren Kosten aufgrund mehrerer Bauteile gibt es die nachfolgenden Nachteile, wie zusätzliche Schnittstellen und damit ein erhöhtes Leckagerisiko, Mehrkosten in Montage und Logistik aufgrund der höheren Bauteilzahl sowie eine große Tole ranzkette, welche kostentechnische Nachteile sowie montagetechnische und funktionale Risiken birgt. Es ist die Aufgabe der vorliegenden Erfindung, ein Abgassammelrohr zu schaffen, das die oben aufgezeigten Nachteile vermeidet. Die der Erfindung zugrunde liegende Aufgabe wird durch eine Brennkraftmaschine mit einem Kurbelgehäuse und wenigstens einem Zylinderkopf mit mindestens sechs entlang der Längsachse des Zylinderkopfes angeordneten Zylindern, wobei jeder Zylinder mindestens eine Auslassöffnung zum Abführen der Abgase aufweist, an die sich Abgasleitungen anschließen und die Abgasleitungen von wenigstens je drei Zylindern des Zylinderkop fes unter Ausbildung von mindestens zwei integrierten Abgasrohrkanälen zu einer Gesamtabgasleitung bzw. zu einem Flansch zusammenführen, ge schaffen. Attempts to realize the exhaust gas transfer to the top of the engine from a single cast component show various difficulties, in particular in the case of required double-flow exhaust pipes, which then have a particularly long thin and double-flow neck due to the high ATL position. There is a conflict of goals between the ribbing required due to the high dynamic load (to protect the turbocharger from vibration) and the thermomechanical residual stresses. To avoid this conflict of objectives, the exhaust gas piping was there with additional, for. B. realized on the charge air line or the cylinder head, consoles. In addition to the higher costs due to several components, there are the following disadvantages, such as additional interfaces and thus an increased leakage risk, additional costs in assembly and logistics due to the higher number of components and a large tolerance chain, which entails cost-related disadvantages as well as assembly-related and functional risks. It is the object of the present invention to provide an exhaust manifold which avoids the disadvantages indicated above. The object on which the invention is based is achieved by an internal combustion engine with a crankcase and at least one cylinder head with at least six cylinders arranged along the longitudinal axis of the cylinder head, each cylinder having at least one outlet opening for discharging the exhaust gases, to which the exhaust gas lines are connected and the exhaust gas lines of at least merge three cylinders of the Zylinderkop fes to form at least two integrated exhaust pipe ducts to form a total exhaust pipe or a flange.
Ein Ausführungsbeispiel der Erfindung ist in der folgenden Beschreibung näher erläutert, sowie in den Bildern 1 bis 4 dargestellt, denen auch weite re Einzelheiten der Erfindung entnommen werden können. Es zeigen: An embodiment of the invention is explained in more detail in the following description and shown in Figures 1 to 4, from which further details of the invention can be found. Show it:

Als Lösung für die Trennung der Abgasrohrkanäle (1 ) wurde ein Abgas rohrdesign entwickelt, welches einteilig mit getrennten Kanälen bis kurz vor der Turbolader-Flanschfläche ausgeführt ist. Hierbei profitieren die voneinander separierten Abgasrohrkanäle (1 ) von der wesentlich geringeren Bau teiltemperatur, da sich die beiden Kanäle keine bzw. kaum eine gemeinsame Innenwand teilen müssen. Diese gemeinsame Innenwand heizt sich durch den Temperaturstau im Rohr nämlich sehr stark auf und gilt daher als kritischste Stelle. Durch die reduzierte Materialtemperatur bei gleich bleibender Abgastemperatur erhöhen sich die Festigkeitswerte des Materials. Die Verrippung, welche zur Schwingungsabsicherung des Turboladers erforderlich ist, kann aus diesem Grund wesentlich kleiner ausfallen. Die reduzierten Rippen wiederum begünstigen selbst nochmals die thermo mechanische Festigkeit des Abgasrohres, was zu weiteren Materialein- sparungen führt. Der Zielkonflikt zwischen thermomechanischer (low cycle fatigue) und dynamischer (high cycle fatigue) Festigkeit wird somit stark entschärft. Symmetrie: Der gesamte Aufbau des Abgasrohres wird möglichst symmetrisch ausgeführt. Das führt dazu, dass der Turboladerflansch mittig zwischen Zylinder 3 und 4 sitzt. Hierdurch vermeidet man einen S- förmigen und damit spannungstechnisch ungünstigen Hals, wie dies in BildAs a solution for the separation of the exhaust pipe ducts (1), an exhaust pipe design was developed, which is made in one piece with separate ducts until just before the turbocharger flange surface. Here, the separated exhaust pipe ducts (1) benefit from the much lower construction temperature, since the two ducts do not have to or hardly have to share a common inner wall. This common inner wall heats up very strongly due to the temperature build-up in the tube and is therefore considered the most critical point. The material's strength values increase due to the reduced material temperature with the exhaust gas temperature remaining the same. For this reason, the ribbing required to protect the turbocharger from vibrations can be significantly smaller. The reduced fins in turn favor the thermo-mechanical strength of the exhaust pipe, which leads to further material leads to savings. The conflict of aims between thermomechanical (low cycle fatigue) and dynamic (high cycle fatigue) strength is thus greatly alleviated. Symmetry: The entire structure of the exhaust pipe is carried out as symmetrically as possible. As a result, the turbocharger flange is located centrally between cylinders 3 and 4. This avoids an S-shaped neck, which is unfavorable in terms of tension, as shown in the picture
1 dargestellt wird. Ausgeprägte S-Formen des Halses sorgen für erhöhte Biegespannungen unter Temperatureinfluss. Weiterhin ist der Leitungsverlauf des Abgases aus den Querstegen der Segmente der Zylinder 1 - 3 und 4 - 6 nach oben zum Turbolader nicht mittig zwischen Zylinder 3 und 4, sondern jeweils einen Zylinder nach außen versetzt, also zwischen Zylinder1 is shown. Pronounced S-shapes of the neck ensure increased bending stresses under the influence of temperature. Furthermore, the route of the exhaust gas from the crossbars of the segments of cylinders 1 - 3 and 4 - 6 upwards to the turbocharger is not offset centrally between cylinders 3 and 4, but one cylinder outwards, that is, between cylinders
2 und 3 sowie zwischen Zylinder 4 und 5, wie dies in Fig. 3 gezeigt wird. Dies ermöglicht, neben dem größeren Abstand der Leitungen zueinander, auch, dass die Rippen ohne großen Aufwand an insgesamt vier, statt wie sonst üblich zwei Zylinderkopfflanschen angebunden werden können. Die erforderliche Steifigkeit für Fertigung, Handling und Montage wird durch einen dünnen Vollmaterial-Verbindungssteg 4 zwischen den Segmenten der Zylinder 1 - 3 und 4 - 6 realisiert. Der Vollmaterial-Verbindungssteg 4 hat einen positiven Einfluss auf die Temperaturdehnung und den gesamten wärmebedingten Verzug des Bauteils. Die Wärmeausdehnung ist auch durch die geringere Bauteiltemperatur niedriger, wodurch die Abgasleitung komplett einteilig ausgeführt werden kann. Es entfallen somit mehrteilige axial verschiebbare und untereinander abzudichtende Teilstücke der Ab gasleitung, wodurch die Kosten weiter gesenkt werden können. 2 and 3 and between cylinders 4 and 5, as shown in Fig. 3. In addition to the greater distance between the lines, this also enables the ribs to be connected to a total of four, rather than two, cylinder head flanges without great effort. The required rigidity for manufacturing, handling and assembly is achieved by a thin solid material connecting web 4 between the segments of cylinders 1-3 and 4-6. The solid material connecting web 4 has a positive influence on the temperature expansion and the overall thermal distortion of the component. The thermal expansion is also lower due to the lower component temperature, which means that the exhaust pipe can be made in one piece. There are therefore no multi-part axially displaceable and mutually sealed sections of the gas line, whereby the costs can be further reduced.
