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, eine besonders umweltfreundliche Brennkraftmaschine bereitzustellen. Diese Aufgabe wird durch eine erfindungsgemäße Brennkraftmaschine entsprechend dem Anspruch 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The invention is in particular the object of providing a particularly environmentally friendly internal combustion engine. This object is achieved by an internal combustion engine 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 einer Kurbelwellenlagerung zur Aufnahme einer Kurbelwelle und einer Nockenwellenlagerung zur Aufnahme zumindest einer Nockenwelle.The invention relates to an internal combustion engine for a motor vehicle, with a crankshaft bearing for receiving a crankshaft and a camshaft bearing for receiving at least one camshaft.
Es wird vorgeschlagen, dass die Kurbelwellenlagerung und/oder die Nockenwellenlagerung wenigstens ein Magnetlager aufweist. Dadurch kann eine Lagerung der Kurbelwelle und/oder der Nockenwelle vorteilhaft entlastet oder gar ersetzt werden, wodurch die Lagerung der Kurbelwelle und/oder der Nockenwelle besonders reibungs- und verschleißarm ausgeführt werden kann. Die Lagerung der Kurbelwelle und/oder der Nockenwelle kann besonders langlebig und verlustarm ausgeführt werden, wodurch ein Wirkungsgrad und eine Lebensdauer der Brennkraftmaschine erhöht werden kann. Dadurch kann ein Schadstoffausstoß und ein Bauteilverschleiß der Brennkraftmaschine reduziert werden, wodurch eine besonders umweltfreundliche Brennkraftmaschine bereitgestellt werden kann.It is proposed that the crankshaft bearing and / or the camshaft bearing has at least one magnetic bearing. Thereby, a bearing of the crankshaft and / or the camshaft can be advantageously relieved or even replaced, whereby the bearing of the crankshaft and / or the camshaft can be performed particularly friction and wear. The bearing of the crankshaft and / or the camshaft can be made particularly durable and low-loss, whereby an efficiency and a life of the internal combustion engine can be increased. As a result, pollutant emissions and component wear of the internal combustion engine can be reduced, whereby a particularly environmentally friendly internal combustion engine can be provided.
Weiter wird vorgeschlagen, dass das Magnetlager zumindest einen Permanentmagneten aufweist, wodurch ein Energiebedarf für das Magnetlager gering gehalten werden kann.It is further proposed that the magnetic bearing has at least one permanent magnet, whereby an energy requirement for the magnetic bearing can be kept low.
Um Kosten einzusparen und die Komplexität zu reduzieren, ist es insbesondere vorteilhaft, wenn das Magnetlager lediglich Permanentmagneten aufweist, wodurch auf eine Energieversorgung des Magnetlagers und auf eine aufwendige Sensorik verzichtet werden kann. Durch das Magnetlager, das lediglich Permanentmagneten aufweist und dadurch passiv ausgebildet ist, kann ein von einer elektrischen Energieversorgung unabhängiges Magnetlager bereitgestellt werden, wodurch auf aufwendige und teure Maßnahmen zur Bereitstellung einer Notlaufeigenschaft verzichtet werden kann.To save costs and reduce complexity, it is particularly advantageous if the magnetic bearing has only permanent magnets, which can be dispensed with an energy supply of the magnetic bearing and a complex sensor. Due to the magnetic bearing, which has only permanent magnets and is thus made passive, can be provided independent of an electrical power supply magnetic bearing, which can be dispensed with costly and expensive measures to provide a Notlaufeigenschaft.
Weitere Vorteile ergeben sich aus der folgenden Figurenbeschreibung. In der einzigen Figur ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Figur, die Figurenbeschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages will become apparent from the following description of the figures. In the single figure, an embodiment of the invention is shown. The figure, the description of the figures and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into meaningful further combinations.

Zur Aufnahme der nicht dargestellten Nockenwelle weist die Brennkraftmaschine eine nicht dargestellte Nockenwellenlagerung auf. Die Nockenwellenlagerung lagert die Nockenwelle drehbar in oder auf einem nicht dargestellten Zylinderkopf der Brennkraftmaschine. Zur Bereitstellung einer besonders reibungsarmen Lagerung der Nockenwelle weist die Nockenwellenlagerung mehrere Magnetlager auf. Die Nockenwellenlagerung ist analog zu der Kurbelwellenlagerung
