Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to an internal combustion engine according to the preamble of claim 1.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, die Brennkraftmaschine im Hinblick auf eine Demontierbarkeit eines Zylinderkopfs zu verbessern. Sie wird durch eine erfindungsgemäße Ausgestaltung entsprechend dem Anspruch 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The invention is in particular the object of improving the internal combustion engine with respect to a disassembly of a cylinder head. It is achieved by an embodiment according to the invention according to claim 1. Further developments of the invention will become apparent from the dependent claims.
Die Erfindung geht aus von einer Brennkraftmaschine für ein Kraftfahrzeug, mit einem Zylinderkopf, welcher eine erste Dichtfläche zur Abdichtung gegenüber einem Steuergehäusedeckel und eine zweite Dichtfläche zur Abdichtung gegenüber einem Kurbelwellengehäuse aufweist.The invention relates to an internal combustion engine for a motor vehicle, with a cylinder head, which has a first sealing surface for sealing against a control housing cover and a second sealing surface for sealing against a crankcase.
Es wird vorgeschlagen, dass die erste Dichtfläche und die zweite Dichtfläche einen inneren Winkel ungleich 90 Grad einschließen, wodurch eine Notwendigkeit einer Demontage des Steuergehäusedeckels vor einer Demontage des Zylinderkopfs der Brennkraftmaschine entfallen kann. Hierdurch kann insbesondere ein Ausbau der gesamten Brennkraftmaschine aus dem Kraftfahrzeug zur Demontage des Zylinderkopfs vermieden werden. Hierdurch können Kosten bei der Demontage des Zylinderkopfs eingespart werden, wodurch die Brennkraftmaschine im Hinblick auf die Demontierbarkeit des Zylinderkopfs verbessert werden kann. Unter einem „inneren Winkel” soll in diesem Zusammenhang insbesondere ein Winkel zwischen den zwei Dichtflächen verstanden werden, welcher im Inneren des Zylinderkopfs gebildet ist.It is proposed that the first sealing surface and the second sealing surface include an inner angle other than 90 degrees, whereby a need for disassembly of the control housing cover may be omitted before disassembly of the cylinder head of the internal combustion engine. In this way, in particular an expansion of the entire internal combustion engine from the motor vehicle for disassembly of the cylinder head can be avoided. As a result, costs can be saved in the disassembly of the cylinder head, whereby the internal combustion engine can be improved in terms of the disassembly of the cylinder head. An "inner angle" is to be understood in this context in particular an angle between the two sealing surfaces, which is formed in the interior of the cylinder head.
Insbesondere ist es vorteilhaft, wenn der innere Winkel ein stumpfer Winkel ist, wodurch realisiert werden kann, dass es bei einer Demontage des Zylinderkopfs zu einer Vergrößerung eines Dichtspalts zwischen dem Zylinderkopf und dem Steuergehäusedeckel kommt. Dementsprechend kann realisiert werden, dass es bei einer Montage des Zylinderkopfs zu einer Verkleinerung eines Dichtspalts zwischen dem Zylinderkopf und dem Steuergehäusedeckel kommt, wodurch eine zuverlässige Abdichtung realisiert werden kann. Unter einem „stumpfen Winkel” soll in diesem Zusammenhang insbesondere ein Winkel größer als 90 Grad und kleiner als 180 Grad verstanden werden.In particular, it is advantageous if the inner angle is an obtuse angle, as a result of which it can be realized that an expansion of a sealing gap between the cylinder head and the control housing cover occurs when the cylinder head is disassembled. Accordingly, it can be realized that, when the cylinder head is mounted, the size of the seal gap between the cylinder head and the timing cover becomes smaller, whereby a reliable seal can be realized. In this context, an "obtuse angle" is to be understood as meaning, in particular, an angle greater than 90 degrees and less than 180 degrees.
Ferner wird vorgeschlagen, dass das Kurbelwellengehäuse der Brennkraftmaschine eine Dichtfläche zur Abdichtung gegenüber dem Steuergehäusedeckel aufweist, die winklig zu der ersten Dichtfläche des Zylinderkopfs orientiert ist, wodurch bei einer Montage des Steuergehäusedeckels eine präzise Ausrichtung des Steuergehäusedeckels erreicht werden kann. Unter „winklig zueinander orientiert” soll in diesem Zusammenhang insbesondere verstanden werden, dass die Dichtfläche des Kurbelwellengehäuses zur Abdichtung gegenüber dem Steuergehäusedeckel und die erste Dichtfläche des Zylinderkopfs in einem montierten Zustand einen Winkel ungleich 180 Grad zueinander aufweisen.It is also proposed that the crankshaft housing of the internal combustion engine has a sealing surface for sealing against the control housing cover, which is oriented at an angle to the first sealing surface of the cylinder head, whereby a precise alignment of the control housing cover can be achieved during assembly of the control housing cover. By "angled towards each other" is to be understood in this context, in particular, that the sealing surface of the crankshaft housing to seal against the control housing cover and the first sealing surface of the cylinder head in an assembled state have an angle not equal to 180 degrees to each other.
In einer weiteren bevorzugten Ausgestaltung der Erfindung wird vorgeschlagen, dass das Kurbelwellengehäuse der Brennkraftmaschine die erste Dichtfläche zur Abdichtung gegenüber dem Steuergehäusedeckel und eine zweite Dichtfläche zur Abdichtung gegenüber dem Zylinderkopf aufweist, welche einen inneren Winkel ungleich 90 Grad einschließen, wodurch eine hohe Dichtwirkung erreicht werden kann. Unter einem „inneren Winkel” soll in diesem Zusammenhang insbesondere ein Winkel zwischen den zwei Dichtflächen verstanden werden, welcher im Inneren des Kurbelwellengehäuses gebildet ist.In a further preferred embodiment of the invention it is proposed that the crankshaft housing of the internal combustion engine has the first sealing surface for sealing against the control housing cover and a second sealing surface for sealing against the cylinder head, which include an inner angle not equal to 90 degrees, whereby a high sealing effect can be achieved , An "inner angle" should be understood in this context, in particular an angle between the two sealing surfaces, which is formed in the interior of the crankcase.
Ferner wird vorgeschlagen, dass die Brennkraftmaschine einen einteiligen Steuergehäusedeckel umfasst, wodurch ein reduzierter Montageaufwand und eine zuverlässige, insbesondere stirnseitige, Abdichtung des Kurbelwellengehäuses und/oder des Zylinderkopfs realisiert werden kann.It is also proposed that the internal combustion engine comprises a one-piece control housing cover, whereby a reduced assembly costs and a reliable, in particular end-side, sealing of the crankshaft housing and / or the cylinder head can be realized.
