Abstract
Description
Die Erfindung bezieht sich auf einen flüssigkeitsgekühlten Zylinderkopf für eine Mehrzylinder-Brennkraftmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a liquid-cooled Cylinder head for a multi-cylinder internal combustion engine according to the preamble of claim 1.
Bei einem bekannten Zylinderkopf dieser Art (DE-OS 35 16 453) wird eine erheblich vereinfachte Herstellung dadurch erreicht, daß anstelle eines einzigen großen, teuren und bruchgefährdeten Gießkerns eine der Zahl der Zylinder bzw. Brennräume entsprechende Anzahl von kleinen Einzelgießkernen in die Gußform eingesetzt wird.In a known cylinder head of this type (DE-OS 35 16 453) a considerably simplified production is achieved that instead of one big, expensive, and fragile Casting core one corresponding to the number of cylinders or combustion chambers Number of small individual casting cores inserted in the mold becomes.
Die Erfindung bezweckt eine weiter vereinfachte Herstellung eines derartigen Zylinderkopfes, was erfindungsgemäß dadurch erreicht wird, daß die Zündkerzen- oder Einspritzdüsen-Schächte den Flüssigkeits-Sammelkanal schneiden und gegenüber diesem durch eingepreßte Hülsen abgedichtet sind.The invention aims at a further simplified production of such a cylinder head, which according to the invention thereby is achieved that the spark plug or injector wells cut and opposite the liquid collection channel are sealed by pressed sleeves.
Bei dem erfindungsgemäßen Zylinderkopf können alle Zündkerzen bzw. Einspritzdüsen-Schächte zusammen mit dem Flüssigkeits- Sammelkanal mittels eines einzigen Gießkerns erzeugt werden, der äußerst stabil ist und eine optimale Lagerung der die Schächte bildenden Kernabschnitte ermöglicht. Außerdem wird eine sehr gute Entgasung des den Flüssigkeits-Sammelkanal erzeugenden Kernabschnittes über die die Schächte erzeugenden Kernabschnitte beim Gießen erreicht, womit das Entstehen von Lunkern vermieden wird.In the cylinder head according to the invention, all spark plugs can or injection nozzle shafts together with the liquid Collecting channel can be generated by means of a single casting core, which is extremely stable and optimal storage of the shafts forming core sections. It also becomes a very good degassing of the one producing the liquid collecting duct Core section over the core sections producing the shafts achieved during casting, thus avoiding the formation of cavities becomes.
Ein Ausführungsbeispiel der Erfindung wird im folgenden unter Bezugnahme auf die Zeichnungen beschrieben. Es zeigt:An embodiment of the invention is described below Described with reference to the drawings. It shows:
Fig. 1 einen Querschnitt eines wassergekühlten Zylinderkopfes Fig. 1 shows a cross section of a water-cooled cylinder head
Fig. 2 eine perspektivische Darstellung eines Gießkerns im Schnitt und Fig. 2 is a perspective view of a casting core in section and
Fig. 3 einen Querschnitt eines Gießkerns für eine abgewandelte Ausführung eines Zylinderkopfes Fig. 3 shows a cross section of a casting core for a modified embodiment of a cylinder head
Der in Fig. 1 dargestellte Zylinderkopf 1 für eine Mehrzylinder- Brennkraftmaschine ist in üblicher Weise für jeden Zylinder mit einem Brennraum 2 versehen, dessen Wand durch Wasser ge kühlt ist, das eine Kühlwasserkammer 3 durchströmt. Die Kammer 3 ist von einem Dom 4 durchsetzt, durch welchen sich ein Zündkerzenschacht 5 erstreckt. Jede Kühlwasserkammer 3 erhält das Kühlwasser durch Kanäle 6 aus dem nicht gezeigten Zylinderblock und ist durch einen oder mehrere Steigleitungen 7 mit einem Abfluß-Sammelkanal 8 in Verbindung, der sich längs des Zylinderkopfes 1 erstreckt. Die Zündkerzenschächte 5 schneiden den Sammelkanal 8 an und sind gegenüber diesem jeweils durch eine eingepreßte Hülse 9 abgedichtet. Dadurch besteht die Möglichkeit, den Sammelkanal 8 und alle Zündkerzen schächte 5 mit Hilfe eines einzigen Gießkerns zu erzeugen.The cylinder head shown in FIG. 1 1 for a multi-cylinder internal combustion engine is provided in a conventional manner for each cylinder with a combustion chamber 2, the wall of which is cooled by water ge, which flows through a cooling water chamber 3. The chamber 3 is penetrated by a dome 4 through which a spark plug shaft 5 extends. Each cooling water chamber 3 receives the cooling water through channels 6 from the cylinder block, not shown, and is connected through one or more risers 7 to a drain collecting channel 8 , which extends along the cylinder head 1 . The spark plug shafts 5 cut the collecting channel 8 and are each sealed off from this by a pressed-in sleeve 9 . This makes it possible to generate the collecting duct 8 and all the spark plug shafts 5 with the aid of a single casting core.
Ein derartiger Gießkern ist für eine 4-Zylinder-Brennkraftma schine in Fig. 2 dargestellt. Er weist einen Abschnitt 12 auf, der zur Formung des Sammelkanals 8 dient und an den die Kernabschnitte 13 angeformt sind, mit denen die Zündkerzen schächte 5 des Zylinderkopfes erzeugt werden. Durch den ein teiligen Gießkern für den Sammelkanal 8 und alle Zündkerzen schächte 5 ergibt sich eine äußerst rationelle Fertigung. Außerdem wird eine sehr stabile Lagerung der die Zündkerzen schächte 5 erzeugenden Gießkernabschnitte 13 erreicht. Schließlich findet eine optimale Entgasung des Gießkernabschnit tes 12 beim Gießvorgang statt, da die entstehenden Gase durch die Gießkernabschnitte 13 hindurch nach oben entweichen kön nen, so daß die Entstehung von Lunkern wirksam verhindert ist.Such a casting core is shown for a 4-cylinder internal combustion engine in Fig. 2. It has a section 12 which serves to form the collecting duct 8 and to which the core sections 13 are formed, with which the spark plug shafts 5 of the cylinder head are produced. The one-piece casting core for the collecting duct 8 and all the spark plug shafts 5 results in extremely efficient production. In addition, a very stable storage of the spark plug shafts 5 producing core sections 13 is achieved. Finally, optimal degassing of the Gießkernabschnit tes 12 takes place during the casting process, since the resulting gases can escape through the casting core sections 13 upwards, so that the formation of cavities is effectively prevented.
Fig. 3 zeigt im Schnitt einen Gießkern, der für einen Zylinder kopf verwendbar ist, bei dem die Zündkerzenschächte den Sammel kanal nicht anschneiden, sondern direkt schneiden. Demzufolge erstrecken sich von dem Gießkernabschnitt 12 , der den Sammel kanal bildet, miteinander fluchtende Gießkernabschnitte 13 a und 13 b nach oben und unten, welche zusammen den Zündkerzen schacht erzeugen. Die Trennung zwischen dem Sammelkanal und jedem Zündkerzenschacht erfolgt wiederum durch eine eingepaßte Hülse. Dieser Gießkern ist besonders stabil. Fig. 3 shows in section a casting core that can be used for a cylinder head, in which the spark plug shafts do not cut the collecting channel, but cut directly. Accordingly, from the casting core section 12 which forms the collecting channel, mutually aligned casting core sections 13 a and 13 b extend up and down, which together produce the spark plug shaft. The separation between the collecting duct and each spark plug shaft is again made by a fitted sleeve. This core is particularly stable.
Die Erfindung ist nicht auf das dargestellte Ausführungsbei spiel eines Zylinderkopfes für eine fremdgezündete Brennkraft maschine beschränkt, sondern gleichermaßen für den Zylinder kopf einer Diesel-Brennkraftmaschine verwendbar, wobei anstelle der Zündkerze 10 von Fig. 1 eine Einspritzdüse zum Einsatz kommt.The invention is not limited to the illustrated exemplary embodiment of a cylinder head for a spark-ignited internal combustion engine, but can equally be used for the cylinder head of a diesel internal combustion engine, an injection nozzle being used instead of the spark plug 10 of FIG. 1.
