Abstract
Die Erfindung betrifft einen Zylinderkopf (1) für eine Brennkraftmaschine mit zumindest einem Gaswechselkanal (3), insbesondere einem Auslasskanal (2). Um Strömungsablösungen zu vermeiden und um Ablagerungen zu reduzieren ist vorgesehen, dass der Gaswechselkanal (3), zumindest abschnittsweise, zumindest eine Oberflächenstruktur (7) aufweist.The invention relates to a cylinder head (1) for an internal combustion engine having at least one gas exchange channel (3), in particular an outlet channel (2). In order to avoid flow separation and to reduce deposits, it is provided that the gas exchange channel (3), at least in sections, has at least one surface structure (7).
Description
Die Erfindung betrifft einen Zylinderkopf für eine Brennkraftmaschine mit zumindest einem Gaswechselkanal, insbesondere einem Auslasskanal.The The invention relates to a cylinder head for an internal combustion engine with at least one gas exchange channel, in particular an outlet channel.
Es ist bekannt, dass mit einer golfballähnlichen Oberflächenstruktur Strömungsverluste vermindert werden können.It It is known that with a golf ball-like surface structure Flow losses can be reduced.

Es ist die Aufgabe der Erfindung, Strömungsverluste durch Ablöseerscheinungen in Gaswechselkanälen zu vermindern. Eine weitere Aufgabe ist es, die Bildung von Ablagerungen zu reduzieren.It The object of the invention, flow losses through To reduce detachment phenomena in gas exchange channels. Another task is to reduce the formation of deposits.
Erfindungsgemäß wird dies dadurch erreicht, dass der Gaswechselkanal, zumindest abschnittsweise, zumindest eine Oberflächenstruktur aufweist, wobei vorzugsweise die Oberflächenstruktur durch Vertiefungen und/oder Erhebungen gebildet ist.According to the invention this achieved in that the gas exchange channel, at least in sections, has at least one surface structure, wherein preferably the surface structure by depressions and / or elevations is formed.
Die Vertiefungen oder Erhebungen können regelmäßig oder unregelmäßig angeordnet sein.The Deepening or surveys can be regular or irregularly arranged.
Besonders vorteilhaft ist es, wenn die Vertiefungen oder Erhebungen im Bereich zumindest einer Strömungsumlenkung des Gaswechselkanals angeordnet sind, wobei vorzugsweise die Vertiefungen oder Erhebungen im Bereich einer Bogeninnenseite der Strömungsumleitung angeordnet sind.Especially It is advantageous if the depressions or elevations in the area at least one flow deflection of the gas exchange channel are arranged, wherein preferably the recesses or elevations in the area of an arc inside the flow diversion are arranged.
Die Vertiefungen oder Erhebungen können gusstechnisch hergestellt werden.The Recesses or elevations can be produced by casting become.
In einer bevorzugten Ausführung ist vorgesehen, dass die Vertiefungen oder Erhebungen im Wesentlichen teilkugelförmig geformt sind. Alternativ dazu kann auch vorgesehen sein, dass die Vertiefungen oder Erhebungen im Grundriss elliptisch oder eckig ausgebildet sind.In A preferred embodiment provides that the depressions or elevations formed substantially part-spherical are. Alternatively, it can also be provided that the depressions or elevations in the plan are elliptical or angular.
Die Höhe der Erhebungen oder Vertiefungen betragt mindestens 0,1 mm. Der größte Durchmesser und der Abstand zwischen den Vertiefungen oder Erhebungen sollte mindestens 1 mm betragen.The Height of the surveys or depressions is at least 0.1 mm. The largest diameter and the distance between the depressions or elevations should be at least 1 mm be.
In weiterer Ausführung der Erfindung kann vorgesehen sein, dass die Vertiefungen oder Erhebungen, zumindest teilweise, unterschiedliche Höhen, Durchmesser, Abstände und/oder Formen aufweisen.In further embodiment of the invention can be provided that the depressions or elevations, at least partially, different Heights, diameters, distances and / or shapes.
Die Erfindung wird im Folgenden anhand der Figuren näher erläutert. Es zeigen:The The invention will be explained in more detail below with reference to FIGS. Show it:
