Abstract
Vorkammerzündsystem für eine fremd gezündete Hubkolben-Brennkraftmaschine mit einem Hohlraum in einem Zylinderkopf der Hubkolben-Brennkraftmaschine, in dem eine Zündvorrichtung mit einer Mittelelektrode angeordnet ist, wobei der Hohlraum mit einem Deckel gegenüber einem Brennraum der Hubkolben-Brennkraftmaschine abgedeckt ist, wobei der Deckel zumindest einen Durchbruch aufweist, der den Hohlraum und den Brennraum Gas führend miteinander verbindet, wobei der Hohlraum von einer Stirnseite der Zündvorrichtung, dem Zylinderkopf selbst und dem Deckel begrenzt ist, wobei der Deckel und der Zylinderkopf stoffschlüssig miteinander verbunden sind.Aufgrund der erfindungsgemäßen Ausgestaltung des Vorkammerzündsystems ist dieses kostengünstig zu fertigen und einfach in den Zylinderkopf zu integrieren.Pre-chamber ignition system for an externally ignited reciprocating internal combustion engine with a cavity in a cylinder head of the reciprocating internal combustion engine, in which an ignition device with a central electrode is arranged, the cavity being covered with a cover opposite a combustion chamber of the reciprocating internal combustion engine, the cover having at least one Has breakthrough which connects the cavity and the combustion chamber leading to each other, the cavity being bounded by an end face of the ignition device, the cylinder head itself and the cover, the cover and the cylinder head being connected to one another in a materially bonded manner. Due to the inventive design of the prechamber ignition system this can be manufactured inexpensively and easily integrated into the cylinder head.

Zum weiteren technischen Umfeld wird ferner auf die deutsche Offenlegungsschrift
Weiter ist aus der deutschen Offenlegungsschrift
Nachteilig an diesen bekannten Vorkammerzündsystemen ist, dass diese in der Herstellung kostenintensiv und nicht immer einfach in den Zylinderkopf integrierbar sind.The disadvantage of these known pre-chamber ignition systems is that they are costly to manufacture and cannot always be easily integrated into the cylinder head.
Aufgabe der vorliegenden Erfindung ist es, eine Maßnahme aufzuzeigen, wie ein Vorkammerzündsystem kostengünstig herstellbar und einfach in den Zylinderkopf integrierbar ist.The object of the present invention is to show a measure how a prechamber ignition system can be produced inexpensively and easily integrated into the cylinder head.
Diese Aufgabe wird durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is achieved by the feature in the characterizing part of claim 1.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous further developments of the invention are described in the subclaims.
In vorteilhafter Weise kann durch die erfindungsgemäße Ausgestaltung des Vorkammerzündsystems ein eigenes Gehäuse für dieses entfallen. Somit ist das Vorkammerzündsystem wesentlich einfacher und platzsparender in den Zylinderkopf einer fremd gezündeten Hubkolben-Brennkraftmaschine verbaubar. Damit der Deckel dauerhaft, d. h. für die Lebensdauer der Hubkolben-Brennkraftmaschine, sicher in dem Zylinderkopf verankert ist, ist dieser mit dem Zylinderkopf stoffschlüssig verbunden.Advantageously, the inventive design of the prechamber ignition system can dispense with its own housing. The prechamber ignition system can thus be installed in the cylinder head of an externally ignited reciprocating internal combustion engine in a much simpler and more space-saving manner. So that the lid is permanent, i. H. for the life of the reciprocating internal combustion engine, is securely anchored in the cylinder head, this is firmly connected to the cylinder head.
In einer Weiterbildung der Erfindung wird der Deckel gem. Anspruch 2 vor dem stoffschlüssigen Verbinden in den Hohlraum des Vorkammerzündsystems eingepresst, da die Befestigung des Deckels nicht über ein einfaches Gewinde möglich ist. Dieses verliert mit der Temperaturbelastung die Vorspannung und würde sich ungewünscht lockern, was Glühzündungen und auch zu einer Zerstörung des Vorkammerzündsystems führen würde und in Folge zu einem Totalschaden der Brennkraftmaschine. Durch diese Maßnahme gem. Anspruch 2 ist ferner ist eine optimale Lagepositionierung des Deckels in dem Zylinderkopf möglich.In a further development of the invention, the cover according to claim 2 is pressed into the cavity of the prechamber ignition system before the material connection, since the cover cannot be fastened via a simple thread. This loses the preload with the temperature load and would be loosened undesirably, which would lead to glow ignitions and also to the destruction of the prechamber ignition system and consequently to a total loss of the internal combustion engine. This measure according to claim 2 also enables optimal positioning of the cover in the cylinder head.
Besonders bevorzugt wird der Deckel mit dem Zylinderkopf gemäß Anspruch 3 verlötet oder verschweißt. Beim Schweißen kann beispielsweise Hochenergiestrahlschweißen, wie z. B. Laserschweißen, oder auch Elektrodenschweißen zum Einsatz kommen.The cover is particularly preferably soldered or welded to the cylinder head according to
Die Ausgestaltung gemäß Patentanspruch 4 gewährleistet, dass bei hohen Zylinderinnendrücken der Deckel nicht in den Hohlraum des Vorkammerzündsystems gedrückt werden kann.The configuration according to
Die Ausgestaltung gemäß Patentanspruch 5 gewährleistet, dass der Deckel beim Betrieb der Brennkraftmaschine nicht in den Brennraum gelangen kann, was ebenfalls zu einem Totalschaden der Brennkraftmaschine führen würde.The embodiment according to patent claim 5 ensures that the cover cannot get into the combustion chamber when the internal combustion engine is in operation, which would likewise lead to a total loss of the internal combustion engine.
