Description
Die Erfindung betrifft ein System zur Übertragung von Energie in einem Zylinderkopf.The invention relates to a system for transmitting energy in a cylinder head.
Die
Das erfindungsgemäße System zur Übertragung von Energie in einem Zylinderkopf eines Verbrennungsmotors umfasst einen Zylinderkopf für einen Verbrennungsmotor und einen Verbrennungsmotor. Der Zylinderkopf umfasst ein nockengetriebenes Ventil, einen Nocken, einen Zylinderkopfölkreislauf zur Versorgung des Zylinderkopfes mit Öl, und eine hydraulische und/oder pneumatische Übertragungsvorrichtung zur Übertragung von Energie zwischen dem Nocken und dem Ventil. Die Übertragungsvorrichtung ist mit dem Zylinderkopfölkreislauf derart verbunden, dass Öl zwischen der Übertragungsvorrichtung und dem Zylinderkopfölkreislauf transferiert werden kann.The system according to the invention for the transmission of energy in a cylinder head of an internal combustion engine comprises a cylinder head for an internal combustion engine and an internal combustion engine. The cylinder head includes a cam-driven valve, a cam, a cylinder head oil circuit for supplying the cylinder head with oil, and a hydraulic and / or pneumatic transmission device for transmitting energy between the cam and the valve. The transfer device is connected to the cylinder head oil circuit such that oil can be transferred between the transfer device and the cylinder head oil circuit.
Im Rahmen der Erfindung hat sich gezeigt, dass die beim Ventilöffnungsvorgang in die bewegten Teile des Systems eingetragene Energie nicht vollständig an die Nockenwelle zurückgestellt wird. Vielmehr wird Energie, welche nicht zurückgespeist wird, an die Umgebung abgegeben. Somit kann diese Energie nicht mehr vorteilhaft innerhalb des Systems genutzt werden.In the context of the invention has been shown that the enlisted in the valve opening operation in the moving parts of the system energy is not fully restored to the camshaft. Rather, energy that is not fed back is released to the environment. Thus, this energy can no longer be used advantageously within the system.
Das erfindungsgemäße System ermöglicht eine Nutzung von Energie, welche von dem Nocken transferiert wird. Energie, welche beim Schließvorgang des Ventils nicht an die Nockenwelle zurückgegeben wird, wird an den Zylinderkopfölkreislauf übertragen. Die so übertragene Energie steht dann dem System zur weiteren Nutzung zur Verfügung. Dadurch wird weniger Energie an die Umgebung abgegeben, was einen effizienten Betrieb des Systems ermöglicht.The system according to the invention allows use of energy which is transferred from the cam. Energy, which is not returned to the camshaft during the closing operation of the valve, is transmitted to the cylinder head oil circuit. The energy thus transferred is then available to the system for further use. As a result, less energy is released to the environment, allowing efficient operation of the system.
Die abhängigen Ansprüche beschreiben vorteilhafte Ausführungsformen der Erfindung.The dependent claims describe advantageous embodiments of the invention.
Ein bevorzugtes Ausführungsbeispiel wird anhand der folgenden Figur näher erläutert.A preferred embodiment will be explained in more detail with reference to the following figure.
Der Verbrennungsmotor
Eine Trennung des Zylinderkopfölkreislaufs
Der Zylinderkopfölkreislauf
Eine Verwendung von Öl mit einer geringeren Viskosität ermöglicht eine Reduktion von Reibung, welche innerhalb des Systems
Der Zylinderkopf
Energie, welche nicht zum Schalten des Ventils
Die Übertragungsvorrichtung
Als Ölpumpe
So wird es ermöglicht, die gesamte Energie, welche von dem Nocken zur Verfügung gestellt wird, innerhalb des Systems
Die erste Energie entspricht mindestens einer Energie, welche für das Schalten des Ventils
So wird sichergestellt, dass immer genug Energie an das Ventil übertragen wird, damit das Ventil
Der Energiespeicher
Der Öldruckspeicher speichert Energie durch das Aufbauen eines Öldrucks. Dieser wird verwendet, um den Zylinderkopfölkreislauf
