Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine, insbesondere eines Kraftfahrzeugs, mit wenigstens einem Arbeitszylinder und mit einem Zylinderkopf, welcher den wenigstens einen Arbeitszylinder verschließt und jeweils wenigstens ein Einlassventil und ein Auslassventil für jeden Arbeitszylinder aufweist, die in geschlossenem Zustand jeweils an einem Ventilsitzring anschlagen, wobei wenigstens ein Brennraumeinlegeelement in wenigstens einem Arbeitszylinder vorgesehen ist, welches eine dem Arbeitszylinder zugewandte Wandung des Zylinderkopfes wenigstens teilweise bedeckt, gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an internal combustion engine, in particular a motor vehicle, with at least one working cylinder and with a cylinder head, which closes the at least one working cylinder and at least one inlet valve and one outlet valve for each each working cylinder, which in the closed state respectively abut on a valve seat ring, wherein at least one combustion chamber insertion element is provided in at least one working cylinder, which is a the working cylinder facing wall of the cylinder head at least partially covered, according to the preamble of the claim 1.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, eine Lebensdauer von Zylinderköpfen zu erhöhen.Of the Invention is based on the object, a life of cylinder heads to increase.
Diese Aufgabe wird erfindungsgemäß durch eine Brennkraftmaschine der o. g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.These The object is achieved by an internal combustion engine the o. g. Art solved with the features characterized in claim 1. Advantageous embodiments of the invention are in the other Claims described.
Dazu ist es bei einer Brennkraftmaschine der o. g. Art erfindungsgemäß vorgesehen, dass das Brennraumeinlegeelement wenigstens einen Ventilsitzring aufnimmt, wobei das Brennraumeinlegeelement aus einer Aluminiumlegierung hergestellt ist.To it is in an internal combustion engine o. g. Art provided according to the invention, the combustion chamber insertion element has at least one valve seat ring receiving, wherein the combustion chamber insert element made of an aluminum alloy is made.
Dies hat den Vorteil, dass die Lebensdauer des Zylinderkopfes begrenzende Bereiche verbessert sind, so dass auch bei steigender Leistung der Brennkraftmaschine eine gewünschte Lebensdauer des Zylinderkopfes erhalten bleibt. Weiterhin unterstützt das Brennraumeinlageelement ein schnelles Aufwärmen eines Brennraumes im Arbeitszylinder nach einem Kaltstart, so dass sich ein verbessertes Emissionsverhalten ergibt.This has the advantage of limiting the life of the cylinder head Areas are improved, so that even with increasing power of the internal combustion engine obtain a desired life of the cylinder head remains. Furthermore, the combustion chamber insert element supports a rapid warming up of a combustion chamber in the working cylinder a cold start, so that an improved emission behavior results.
In einer bevorzugten Ausführungsform nimmt das Brennraumeinlegeelement wenigstens einen Ventilsitzring für das Einlassventil oder das Auslassventil auf.In In a preferred embodiment, the combustion chamber loading element takes at least one valve seat ring for the inlet valve or the exhaust valve on.
Ein maximaler Strömungsquerschnitt im Bereich der durch das Brennraumeinlageelement ausgebildeten Ventilsitzringe wird dadurch erzielt, dass das Brennraumeinlegeelement derart ausgebildet und angeordnet ist, dass es ausgehend vom Ventilsitzring einen Einlasskanal und/oder Auslasskanal im Zylinderkopf über eine vorbestimmte axiale Länge des Einlasskanals und/oder Auslasskanals in Umfangsrichtung vollständig umschließt.One maximum flow cross-section in the area through the Combustion chamber insert formed valve seat inserts is characterized achieved that the combustion chamber insertion element is formed and is arranged, that it starting from the valve seat ring an inlet channel and / or exhaust duct in the cylinder head over a predetermined axial length of the inlet channel and / or outlet channel in Completely encloses circumferential direction.
Zum sicheren Abdichten gegen den Zylinderkopf sowie der Gaswechselkanäle gegeneinander ist an einem dem Arbeitszylinder abgewandeten Ende des Brennraumeinlegeelementes im Bereich des Einlasskanals und/oder Auslasskanals ein Dichtring zwischen dem Brennraumeinlageelement und dem Zylinderkopf angeordnet.To the safe sealing against the cylinder head and the gas exchange channels against one another is on a side facing away from the working cylinder of the Brennraumeinlegeelementes in the region of the inlet channel and / or Outlet channel a sealing ring between the combustion chamber insert element and the cylinder head arranged.
In einer bevorzugten Ausführungsform ist der Ventilsitzring als gefügtes Bauteil aus Sinterwerkstoff in das Brennraumeinlageelement integriert.In A preferred embodiment is the valve seat ring as an assembled component of sintered material in the combustion chamber insert element integrated.
Dadurch, dass im Zylinderkopf eine Aussparung zur Aufnahme des Brennraumeinlageelement ausgebildet ist, benötigt des Brennraumeinlageelement keinen zusätzlichen Bauraum im Arbeitszylinder.Thereby, in that a recess for receiving the combustion chamber insert element is formed in the cylinder head is needed, the combustion chamber insert element no additional Space in the working cylinder.
Eine einfachere Handhabung bei der Herstellung und Bearbeitung des Zylinderkopfes und des Brennraumeinlageelementes erzielt man dadurch, dass das Brennraumeinlageelement planparallel zur einer dem Arbeitszylinder zugewandten Wandung des Zylinderkopfes ausgebildet ist.A easier handling in the production and processing of the cylinder head and the combustion chamber insert element is achieved in that the Brennraumeinlageelement plane-parallel to a the working cylinder facing wall of the cylinder head is formed.
Die Erfindung wird im Folgenden anhand der Zeichnung näher erläutert. Diese zeigt in der einzigen Figur eine schematische Schnittansicht einer bevorzugten Ausführungsform eines Zylinderkopfes für eine erfindungsgemäße Brennkraftmaschine.The The invention will be explained in more detail below with reference to the drawing explained. This shows in the single figure a schematic Sectional view of a preferred embodiment of a Cylinder head for an inventive Internal combustion engine.
