Description
Die Erfindung betrifft eine Entlüftungsvorrichtung für ölbeladene Gase einer Brennkraftmaschine, wobei die Entlüftungsvorrichtung eine zumindest abschnittsweise an einem Zylinderkopf der Brennkraftmaschine ausgebildete Entlüftungsleitung und an der Brennkraftmaschine eine Verbrennungsluft zuführende Ansauganlage vorgesehen ist, entsprechend dem einleitenden Teil des Anspruchs 1.The invention relates to a ventilation device for oil-laden gases of an internal combustion engine, wherein the ventilation device is provided at least partially formed on a cylinder head of the engine vent line and on the internal combustion engine combustion air supplying intake system, according to the introductory part of claim 1.
Bekannte Entlüftungsvorrichtungen dieser Art weisen eine die Entlüftungsgase aus dem Kurbelgehäuse absaugende Entlüftungsleitung und einen separaten Ölabscheider auf. Eine derartige Entlüftungsvorrichtung ist beispielsweise in der
Nachteilhafterweise sind derartige bekannte Entlüftungsvorrichtungen verhältnismäßig großvolumig und kompliziert ausgeführt, so dass sie bei beengten Einbauverhältnissen nicht ohne weiteres eingesetzt werden können.Disadvantageously, such known venting devices are relatively bulky and complicated, so that they can not be readily used in cramped installation conditions.
Aus der
Aufgabe der Erfindung ist es, eine Entlüftungsvorrichtung zu schaffen, welche trotz problematischer Platzbedingungen im Zylinderkopf dennoch durch diesen hindurch geführt werden kann.The object of the invention is to provide a ventilation device which despite problematic space conditions in the cylinder head can still be passed through it.
Diese Aufgabe wird bei einer Entlüftungsvorrichtung der eingangs genannten Art dadurch gelöst, dass zumindest ein Abschnitt der Entlüftungsleitung der Ansauganlage zugeordnet ist, wobei zumindest eine Gaseintrittsöffnung und eine Gasaustrittsöffnung dieses Abschnittes der Entlüftungsleitung in der Flanschfläche zwischen Zylinderkopf und Ansauganlage liegend ausgebildet sind, wobei in Richtung des Strömungsverlaufes der Gase ein erster Abschnitt der Entlüftungsleitung im Zylinderkopf ausgebildet ist, dann als zweiter Abschnitt der der Ansauganlage zugeordnete folgt und ein dritter Abschnitt der Entlüftungsleitung wiederum im Zylinderkopf ausgebildet ist.This object is achieved in a ventilation device of the type mentioned in that at least a portion of the vent line of the intake system is assigned, wherein at least one gas inlet opening and a gas outlet opening of this section of the vent line are formed lying in the flange between the cylinder head and intake, wherein in the direction of Flow of the gases formed a first portion of the vent line in the cylinder head, then as a second portion of the intake system associated follows and a third portion of the vent line is in turn formed in the cylinder head.
Durch diese erfindungsgemäße Anordnung des einen Abschnittes der Entlüftungsleitung in der Ansauganlage ist gestattet, die gesamte Entlüftungsvorrichtung kompakt auszubilden, wobei durch Entfall von externen Verschlauchungen und entsprechenden Verbindungsstellen und Konstruktionselementen die Entlüftungsvorrichtung montagefreundlich konzipiert ist.This inventive arrangement of a portion of the vent line in the intake system is allowed to make the entire ventilation device compact, with the ventilation device is designed easy to install due to the elimination of external tubing and corresponding connection points and construction elements.
Vorteilhafterweise ist der der Ansauganlage zugeordnete Abschnitt der Entlüftungsleitung unter Ausnutzung eines ohnehin vorhandenen Bauraumes gebildet. Dieser Bauraum erstreckt sich vorzugsweise zwischen zwei vereinzelten Saugrohren der Ansauganlage, wobei dieser Bauraum vor der Montage der Ansauganlage an dem Zylinderkopf zunächst offen ist. Nach der Montage der Ansauganlage ist diese Öffnung des Abschnittes verschlossen, wobei diese Öffnung in der Flanschfläche liegt und vorzugsweise durch eine dem Zylinderkopf zugeordnete Wandung, welche ebenfalls in der Flanschfläche liegt, in eine Gaseintritts- und eine Gasaustrittsöffnung unterteilt ist. Diese Unterteilung kann auch durch entsprechende Gestaltung einer zwischen Ansauganlage und Zylinderkopf liegenden Dichtung erzielt werden.Advantageously, the intake system associated portion of the vent line is formed by utilizing an already existing space. This space preferably extends between two isolated suction pipes of the intake system, this space is initially open before mounting the intake system to the cylinder head. After assembly of the intake system, this opening of the section is closed, wherein this opening is located in the flange and preferably by a cylinder head associated wall, which is also in the flange, is divided into a gas inlet and a gas outlet opening. This subdivision can also be achieved by appropriate design of a seal between the intake system and the cylinder head.
Die über die Entlüftungsvorrichtung abgeführten, ölbeladenen Gase können nach dem Durchströmen der Entlüftungsleitung einem beispielsweise in einer Zylinderkopfhaube integrierten Entlüftungsventil bzw. einer Kombination aus Entlüftungsventil und Ölabscheider zugeführt werden. Eine erhöhte Vorabscheidung zu diesem Zwecke kann in weiterer vorteilhafter Ausgestaltung beispielsweise bereits in dem der Ansauganlage zugeordneten zweiten Abschnitt beispielsweise durch entsprechende gußtechnische Gestaltung erzielt werden.The discharged via the venting device, oil-laden gases can be supplied after flowing through the vent line to an integrated example in a cylinder head cover vent valve or a combination of vent valve and oil separator. An increased pre-separation for this purpose can be achieved in a further advantageous embodiment, for example, already in the second section associated with the intake system, for example, by appropriate casting technology design.
