Description

BrennkraftmaschineInternal combustion engine
Die Erfindung betrifft eine Brennkraftmaschine, insbesondere mit Ventilsteuerung, mit einem Kurbelgehäuse, vorzugsweise mit mehreren in Reihe angeordneten Zylindern, welches vorzugsweise eine Zylinderkopfdichtfläche zum An- schluss eines zumindest einen Einlasskanal aufweisenden Zylinderkopfes aufweist.The invention relates to an internal combustion engine, in particular with valve control, with a crankcase, preferably with a plurality of cylinders arranged in series, which preferably has a cylinder head sealing surface for connecting a cylinder head having at least one intake port.
Bei herkömmlichen Brennkraftmaschinen für Fahrzeuge, insbesondere für Personenkraftfahrzeuge ist der Einlasstrakt an einer Flanschfläche des Zylinderkopfes angeschlossen, von welcher die in den Brennraum führenden Einlasskanäle ausgehen. Die Einlassleitungen der Einlasssammler, sowie gegebenenfalls Verbindungsleitungen zu der Flanschfläche werden häufig als getrennte Bauteile ausgeführt, wodurch der Herstellungs- und Montageaufwand relativ hoch ist. Da diese Elemente zumeist auf derselben Einlassseite der Brennkraftmaschine angeordnet sind, wird auch vergleichsweise viel Bauraum beansprucht.In conventional internal combustion engines for vehicles, in particular for passenger vehicles, the inlet tract is connected to a flange surface of the cylinder head, from which the inlet ducts leading into the combustion chamber originate. The inlet lines of the inlet manifolds, as well as, if applicable, connecting lines to the flange surface, are often designed as separate components, as a result of which the production and assembly effort is relatively high. Since these elements are mostly arranged on the same inlet side of the internal combustion engine, a comparatively large amount of installation space is also required.
Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden, und die Teileanzahl, sowie den beanspruchten Bauraum zu vermindern.The object of the invention is to avoid these disadvantages and to reduce the number of parts and the space required.
Erfindungsgemäß wird dies dadurch erreicht, dass zumindest ein erster Einlasssammler, zumindest eine zum ersten Einlasssammler führende Einlassleitung und zumindest eine den ersten Einlasssammler mit zumindest einem Einlasskanal des Zylinderkopfes verbindende Verbindungsleitung in das Kurbelgehäuse integriert und vorzugsweise einstückig mit dem Kurbelgehäuse ausgebildet sind.According to the invention, this is achieved in that at least one first intake manifold, at least one intake line leading to the first intake manifold and at least one connecting line connecting the first intake manifold with at least one intake port of the cylinder head are integrated in the crankcase and are preferably formed in one piece with the crankcase.
Wesentliche Teile des Einlasstraktes können somit einstückig mit dem Kurbelgehäuse ausgeführt werden.Essential parts of the intake tract can thus be made in one piece with the crankcase.
Vorzugsweise ist dabei vorgesehen, dass zumindest eine Verbindungsleitung für den Anschluss zumindest eines Einlasskanals des Zylinderkopfes im Bereich der Zylinderkopfdichtfläche endet, wobei es besonders platzsparend ist, wenn zumindest ein erster Einlasssammler und zumindest eine Verbindungsleitung auf einer ersten Längsseite des Kurbelgehäuses angeordnet sind.It is preferably provided that at least one connecting line for connecting at least one intake port of the cylinder head ends in the area of the cylinder head sealing surface, it being particularly space-saving if at least one first intake manifold and at least one connecting line are arranged on a first long side of the crankcase.
In weiterer Ausführung der Erfindung ist vorgesehen, dass zumindest ein zweiter Einlasssammler in das Kurbelgehäuse integriert ist, welcher über die Einlassleitungen mit dem ersten Einlasssammler verbunden ist, wobei vorzugsweise der zweite Einlasssammler an einer der ersten Längsseite des Kurbelgehäuses bezüglich der Motorlängsebene gegenüberliegenden zweiten Längsseite des Kurbelgehäuses angeordnet ist. In einer besonders bevorzugten Ausführungsvariante ist dabei weiters vorgesehen, dass zumindest eine Einlassleitung in einer normal auf die Kurbelwellenachse ausgebildeten Querebene zwischen den Zylindern angeordnet ist, und dass zumindest eine Einlassleitung zwischen Kurbelwellenlager und Ölwanne eine die Kurbelwellenachse beinhaltenden Motorlängsebene quert. Die Einlassleitungen sind somit besonders platzsparend unterhalb der Hauptlager des Kurbelwellengehäuses in einem Bogen von einer zur anderen Längsseite des Kurbelgehäuses geführt. Zur Erleichterung von Montagearbeiten ist es vorteilhaft, wenn die Einlassleitung zumindest zwei durch Stopfen verschließbare Zugangsöffnungen zu Lagerschrauben zumindest eines Kurbelwellenlagers aufweist.In a further embodiment of the invention it is provided that at least one second intake manifold is integrated into the crankcase, which is connected to the first intake manifold via the inlet lines, the second intake manifold preferably being located on a second longitudinal side of the crankcase opposite the first longitudinal side of the crankcase with respect to the engine longitudinal plane is arranged. In a particularly preferred embodiment variant, it is further provided that at least one inlet line is arranged between the cylinders in a transverse plane that is normal to the crankshaft axis, and that at least one inlet line between the crankshaft bearing and oil pan crosses an engine longitudinal plane containing the crankshaft axis. The inlet lines are thus guided in a particularly space-saving manner below the main bearing of the crankshaft housing in an arc from one to the other long side of the crankcase. In order to facilitate assembly work, it is advantageous if the inlet line has at least two access openings to the bearing bolts of at least one crankshaft bearing which can be closed by plugs.
Um den Einbau der Kurbelwelle zu ermöglichen, ist dabei vorgesehen, dass das Kurbelgehäuse zweiteilig ausgeführt ist, wobei die Teilungsebene die Kurbelwellenachse beinhaltet und parallel zur Zylinderkopfdichtfläche angeordnet ist, wobei vorzugsweise die Teilungsebene durch den ersten Einlasssammler verläuft.In order to enable the installation of the crankshaft, it is provided that the crankcase is designed in two parts, the parting plane containing the crankshaft axis and being arranged parallel to the cylinder head sealing surface, the parting plane preferably running through the first intake manifold.
Bei einer Brennkraftmaschine mit einem Abgasturbolader und einem Ladeluft- kühler ist es besonders vorteilhaft, wenn der Ladeluftkühler direkt an einer auf der zweiten Längsseite des Kurbelgehäuses angeordneten Flanschfläche anschließbar ist, wobei der zweite Einlasssammler direkt von der Flanschfläche ausgeht. Der Ladeluftkühler wird somit direkt am Kurbelgehäuse angeflanscht.In an internal combustion engine with an exhaust gas turbocharger and a charge air cooler, it is particularly advantageous if the charge air cooler can be connected directly to a flange surface arranged on the second long side of the crankcase, the second intake manifold starting directly from the flange surface. The charge air cooler is thus flanged directly to the crankcase.
Insbesondere bei einer in ein Fahrzeug quer eingebauten Brennkraftmaschine ist es vorteilhaft, wenn der Kühlluftkanal am Kurbelgehäuse befestigbar ist, wobei vorzugsweise der Kühlluftkanal von der ersten Längsseite des Kurbelgehäuses ausgeht und unter der Ölwanne die Motorlängsebene quert, wobei vorzugsweise die Kühlluftleitung benachbart zu einem Ölsumpf der Ölwanne angeordnet ist.Particularly in the case of an internal combustion engine installed transversely in a vehicle, it is advantageous if the cooling air duct can be fastened to the crankcase, the cooling air duct preferably starting from the first longitudinal side of the crankcase and crossing the longitudinal plane of the engine under the oil pan, the cooling air line preferably adjacent to an oil sump of the oil pan is arranged.
Um den beanspruchten Bauraum möglichst klein zu halten, ist es vorteilhaft, wenn - in Richtung der Kurbelwellenachse betrachtet - die Länge des ersten und/oder zweiten Einlasssammlers etwa dem größten Abstand der äußeren Einlassleitungen voneinander entspricht.In order to keep the space required as small as possible, it is advantageous if - viewed in the direction of the crankshaft axis - the length of the first and / or second intake manifold approximately corresponds to the greatest distance between the outer intake lines.
Um einen einfachen Ein- und Ausbau der Pleuelstangen zu ermöglichen, ist in weiterer Ausführung der Erfindung vorgesehen, dass das Kurbelgehäuses zwischen den Einlassleitungen, und vorzugsweise auch zwischen den äußeren Einlassleitungen und stirnseitigen Gehäusewänden zumindest eine Montageöffnung aufweist.In order to enable easy installation and removal of the connecting rods, a further embodiment of the invention provides that the crankcase has at least one assembly opening between the inlet lines, and preferably also between the outer inlet lines and the front housing walls.

Das Kurbelgehäuse 1 für mehrere in Reihe angeordneten Zylindern 2 weist eine Zylinderkopfdichtfläche 3 für den Anschluss eines nicht weiter dargestellten Zylinderkopfes auf. In Fig. 1 ist ein im Kurbelgehäuse 1 angeordneter Kurbeltrieb 4 mit Kurbelwelle 5 und Pleuelstangen 6 eingezeichnet. Die Kurbelwelle 5 ist in Kurbelwellenlagern 7 im Kurbelgehäuse 1 gelagert.The crankcase 1 for a plurality of cylinders 2 arranged in series has a cylinder head sealing surface 3 for the connection of a cylinder head (not shown in any more detail). In Fig. 1 is arranged in the crankcase 1 crank mechanism 4 with crankshaft 5 and connecting rods 6 is drawn. The crankshaft 5 is mounted in crankshaft bearings 7 in the crankcase 1.
Im Kurbelgehäuse 1 ist auf einer ersten Längsseite A ein erster Einlasssammler 8 angeordnet, in welchen mehrere Einlassleitungen 9 einmünden. Vom ersten Einlasssammler 8 gehen weiters im Kurbelgehäuse 1 angeordnete Verbindungsleitungen 10 aus, welche zur Zylinderkopfdichtfläche 3 führen. An die Verbindungsleitungen 10 können nicht weiter dargestellte Einlasskanäle des Zylinderkopfes angeschlossen werden.A first inlet header 8, in which a plurality of inlet lines 9 open, is arranged in the crankcase 1 on a first longitudinal side A. Connecting lines 10, which lead to the cylinder head sealing surface 3, also proceed from the first intake manifold 8 and are arranged in the crankcase 1. Inlet ducts of the cylinder head, not shown, can be connected to the connecting lines 10.
In das Kurbelgehäuse 1 ist weiters an einer zweiten Längsseite B des Kurbelgehäuses 1 ein zweiter Einlasssammler 11 integriert, welcher an eine Flanschfläche 12 grenzt und von welchem die Einlassleitungen 9 ausgehen. Erster Einlasssammler 8 und zweiter Einlasssammler 11 sind somit bezüglich der Motorlängsebene 13 an unterschiedlichen Seiten A, B des Kurbelgehäuses 1 angeordnet.In the crankcase 1, a second inlet header 11 is also integrated on a second longitudinal side B of the crankcase 1, which borders on a flange surface 12 and from which the inlet lines 9 extend. The first intake manifold 8 and the second intake manifold 11 are thus arranged on different sides A, B of the crankcase 1 with respect to the engine longitudinal plane 13.
Die Einlassleitungen 9 sind jeweils im Bereich von auf die Kurbelwellenachse 5a normal angeordneten Querebenen 14 zwischen jeweils zwei Zylindern 2 ausgebildet und unterhalb der Kurbelwelle 5, also im Bereich zwischen den Kurbelwellenlagern 7 und der Ölwanne 15 innerhalb des Kurbelgehäuses 1 zwischen den beiden Einlasssammlern 8, 11 geführt. Zur Betätigung der Lagerschrauben 16 der Kurbelwellenlager 7 weist jede Einlassleitung 9 durch Stopfen 17 verschlossene Zugangsöffnungen 18 auf, welche bei demontierter Ölwanne 15 zugänglich sind.The inlet lines 9 are each formed in the region of transverse planes 14 arranged normally on the crankshaft axis 5a between two cylinders 2 and below the crankshaft 5, that is to say in the region between the crankshaft bearings 7 and the oil pan 15 within the crankcase 1 between the two inlet collectors 8, 11 guided. To actuate the bearing screws 16 of the crankshaft bearings 7, each inlet line 9 has access openings 18 which are closed by plugs 17 and which are accessible when the oil pan 15 is removed.
Direkt an die Flanschfläche 12 des Kurbelgehäuses 1 ist ein Ladeluftkühler 19 angeschlossen, welcher stromabwärts eines nicht weiter dargestellten Abgasturboladers in der Ladeluftleitung 20 vorgesehen ist. An den Ladeluftkühler 19 ist eine am Kurbelgehäuse 1 befestigte Kühlluftleitung 21 angeschlossen, welche außerhalb des Kurbelgehäuses 1, und zwar unterhalb der Ölwanne 15 von der ersten Längsseite A zur zweiten Längsseite B geführt ist. Die Kühlluftleitung 21 ist dabei benachbart zu einem Ölsumpf 22 der Ölwanne 15 angeordnet. Aus Fig. 1 ist ersichtlich, dass die Kühlluftleitung 21 einen im Wesentlichen rechteck- förmigen Querschnitt aufweisen kann.A charge air cooler 19 is connected directly to the flange surface 12 of the crankcase 1 and is provided in the charge air line 20 downstream of an exhaust gas turbocharger (not shown). Connected to the charge air cooler 19 is a cooling air line 21 which is fastened to the crankcase 1 and which is guided outside the crankcase 1, namely below the oil pan 15 from the first longitudinal side A to the second longitudinal side B. The cooling air line 21 is arranged adjacent to an oil sump 22 of the oil pan 15. Out 1 that the cooling air line 21 can have an essentially rectangular cross section.
Wie aus Fig. 4 hervorgeht, weist auch der erste Einlasssammler 8 einen im Wesentlichen rechteckförmigen Querschnitt auf. Die Länge L des ersten Einlasssammlers 8 entspricht dabei im Wesentlichen dem maximalen axialen Abstand a zwischen den äußersten Einlassleitungen 9.As can be seen from FIG. 4, the first inlet header 8 also has a substantially rectangular cross section. The length L of the first inlet header 8 essentially corresponds to the maximum axial distance a between the outermost inlet lines 9.
In den Fig. 2 und Fig. 3 ist mit den Pfeilen K der Kühlluftstrom und mit Pfeilen E der Ladeluftstrom eingezeichnet.In FIGS. 2 and 3 the arrows K indicate the cooling air flow and arrows E the charge air flow.
Das Kurbelgehäuse 1 ist zweiteilig ausgeführt und besteht aus einem oberen Teile la und einem unteren Teil Ib. Die Teilungsebene 23 verläuft in einer die Kurbelwellenachse 5a inkludierenden Ebene parallel zur Zylinderkopfdichtfläche 3, wobei die Teilungsebene 23 den ersten Einlasssammler 8 quert. Durch die Teilung des Kurbelgehäuses 1 ist ein leichter Ein- und Ausbau des Kurbeltriebes 4 möglich.The crankcase 1 is made in two parts and consists of an upper part la and a lower part Ib. The division plane 23 runs in a plane including the crankshaft axis 5a parallel to the cylinder head sealing surface 3, the division plane 23 crossing the first intake manifold 8. By dividing the crankcase 1, an easy installation and removal of the crank mechanism 4 is possible.
Um eine einfache Montage und Demontage der Pleuelstangen 6 zu ermöglichen, weist der untere Teil lb des Kurbelgehäuses 1 zwischen den Einlassleitungen 9, sowie zwischen den äußeren Einlassleitungen 9 und stirnseitigen Gehäusewänden 24, 25 Montageöffnungen 26 auf.In order to enable simple assembly and disassembly of the connecting rods 6, the lower part 1b of the crankcase 1 has mounting openings 26 between the inlet lines 9 and between the outer inlet lines 9 and the front housing walls 24, 25.
