Description

"Zündkerze zum Betreiben eines Verbrennungsmotors" "Spark plug for operating an internal combustion engine"

Die Erfindung bezieht sich auf eine Zündkerze zum Betreiben eines Verbrennungsmotors mit einem den Elektrodenbereich umgebenden geschlossenen kammerartig ausgebildeten Elektrodenraum, der über eine venturidüsenartige Kanalanordnung mit dem Zylinderraum der Kolbenzylinderanordnung in Verbindung steht.The invention relates to a spark plug for operating an internal combustion engine with a closed chamber-like electrode space surrounding the electrode area, which is connected to the cylinder space of the piston-cylinder arrangement via a venturi-like channel arrangement.

Eine in der DE-PS 661 768 beschriebene Zündkerze zeichnet sich durch einen den Elektrodenbereich umgebenden Elektrodenbereich aus, der über eine venturidüsenartige Kanalanordnung mit dem Zylinderraum der Kolbenzylinderanordnung in Verbindung steht. Durch die Form der Zündkammer soll eine vollständige Verbrennung des Gemisches innerhalb der Zündkammer erzielt werden, so daß die Gase ohne Beimischung von halbverbranntem Betriebsstoff in den Zylinder gelangen. Schraubengangfδrmige Nuten in den doppelkonischen Zündkammern geben dem Strahl brennender Gase die Richtung als Streu- bzw. Stichflamme nach der Entzündung des Gemisches in der Vorkammer. Durch die besondere Ausbildung der Masseelektrode sollen immer Funkenbildungen erzielt werden, da die Funkenbildung auf der ganzen Lange der Masseelektrodenenden erfolgen kann, so daß auch schwere Verkrustungen der Elektrodenenden nicht stören können. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diese bekannte Zündkerze dahingehend zu verbessern, daß höhere Verdichtungen zu erreichen sind, ohne daß der Zündfunke erlischt.A spark plug described in DE-PS 661 768 is characterized by an electrode region surrounding the electrode region, which is connected to the cylinder space of the piston-cylinder arrangement via a venturi-like channel arrangement. The shape of the ignition chamber is intended to achieve complete combustion of the mixture within the ignition chamber, so that the gases enter the cylinder without the addition of semi-burned fuel. Spiral-shaped grooves in the double-conical ignition chambers give the jet of burning gases the direction as a scattered or stab flame after ignition of the mixture in the prechamber. Due to the special design of the ground electrode, sparking should always be achieved, since the sparking can take place over the entire length of the ground electrode ends, so that even heavy incrustations of the electrode ends cannot interfere. The present invention has for its object to improve this known spark plug in such a way that higher densities can be achieved without the ignition spark extinguishing.

Diese Aufgabe wird dadurch gelöst, daß der Elektrodenraum über eine gerade Anzahl aufweisender Verbindungskanäle mit einem venturidüsenartigen Raum in Verbindung steht, der die Form eines halben Rotationsellipsoides aufweist. Die Größe dieses venturidüsenartigen Raumes beträgt

Figure imgf000004_0001
- 2 ß .This object is achieved in that the electrode space is connected via an even number of connecting channels to a venturi-like space which has the shape of a half ellipsoid of revolution. The size of this venturi-like space is
Figure imgf000004_0001
- 2 ß.

Weiterhin ist vorgesehen, daß der Elektrodenraum mit dem venturidüsenartigen, in Form eines Rotationsellipsoides ausgebildeten Raum über einen Hauptverbindungskanal in Verbindung steht, und schließlich wird gemäß der Erfindung vorgeschlagen, daß die Verbindungskanäle zwischen dem Elekt roden räum und dem venturidüsenartigen Raum über Einschnitte mit dem Hauptverbindungskanal .in Verbindung stehen.Furthermore, it is provided that the electrode space communicates with the venturi-shaped space in the form of an ellipsoid of revolution via a main connecting channel, and finally it is proposed according to the invention that the connecting channels between the electrodes and the venturi-like space via incisions with the main connecting channel. stay in contact.

Dadurch, daß die Verbindungskanäle zwischen dem Elektrodenraum und dem venturidüsenartigen Raum über Einschnitte mit dem Hauptverbindungskanal in Verbindung stehen, wird die ringförmige Hassenelektrode in ebensoviel Teile wie Verbindungskanäle vorhanden sind geteilt. Hierdurch bekommen die Verbindungskanäle die Eigenschaft resoni erender Höhlen. Zwei aufeinanderfolgende Höhlen oszillieren bei der Zündung in Phasen, die in Opposition stehen.Because the connecting channels between the electrode space and the venturi-like space are connected to the main connecting channel via incisions, the annular hate electrode is divided into as many parts as there are connecting channels. This gives the connecting channels the property of resonating caves. Two successive caves oscillate in phases in opposition to each other when ignited.

Durch die erfindungsgemäße Kerze werden eine sogenannte "heiße" und eine sogenannte "kalte" Anwendung gewährlei stet:A so-called "hot" and a so-called "cold" application are guaranteed by the candle according to the invention:

Die "heiße" Anwendung erfolgt, weil die Rückstände in dem Elektrodenraum vollständig verbrannt werden. Die "kalte" Anwendung wird dadurch bedingt, daß über die massiven Massenelektroden ein rascher Wärmeaustausch erfolgt.The "hot" application takes place because the residues in the electrode space are completely burned off. The "cold" application is due to the fact that rapid heat exchange takes place via the massive mass electrodes.

Hierdurch wird die Bildung vereinzelter Wärmestellen ausgeschaltet, so daß bei einem derart ausgerüsteten Motor höhere Kompressionen möglich sind.This eliminates the formation of isolated heat spots, so that higher compressions are possible with an engine equipped in this way.

Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnungen erläutert. Die Zeichnungen zeigen dabei inEmbodiments of the invention are explained below with reference to the drawings. The drawings show in

Fig. 1 eine erfindungsgemäß ausgebildete Elektrode in Fig. 2 in größerem Maßstab den unteren Bereich des eigentlichen Zündkerzenkörpers und in Fig. 3 eine Draufsicht auf die erfindungsgemäß vorgesehene Einschnittanordnung.1 shows an electrode designed according to the invention in FIG. 2 on a larger scale the lower area of the actual spark plug body and in FIG. 3 a top view of the incision arrangement provided according to the invention.

In Fig. 1 ist mit 1 allgemein eine Zündkerze bezeichnet die über ein Bef estigungsgewi nde 2 festgelegt wird, wobei mit 3 der eigentliche Zündkerzenkörper bezeichnet ist.In Fig. 1, 1 generally designates a spark plug which is fixed via a fastening thread 2, 3 being the actual spark plug body.

In dem Zündkerzenkörper ist ein ELektrodenraum 6 ausgeformt, der über Verbindungskanäle 4 mit einem venturidüsenartigen Raum 5 in Verbindung steht, wobei dieser venturidüsenartige Raum 5, wie dies deutlicher aus Fig. 2 zu ersehen ist, in Form eines halben Rotationsellipsoides ausgebildet ist.In the spark plug body, an electrode space 6 is formed, which is connected via connection channels 4 to a venturi-like space 5, this venturi-like space 5, as can be seen more clearly from FIG. 2, in the form of a half ellipsoid of revolution.

In Fig. 2 sind die Maße

Figure imgf000005_0001
und ß eingetragen, wobei vorzugsweise das Verhältnis derart ist, daß
Figure imgf000005_0002
= 2 ß gewählt wird.2 are the dimensions
Figure imgf000005_0001
and ß entered, the ratio preferably being such that
Figure imgf000005_0002
= 2 ß is selected.

Die Verbindung zwischen dem Elekt roden räum 6 und dem venturidüsenartigen Raum 5 erfolgt über einen Haupt Verbindungskanal 7 und über Verbindungskanäle 4, die in einer geraden Anzahl vorgesehen werden, d. h. also nicht in einer ungeraden Anzahl, sondern in einer jeweils durch zwei teilbaren Anzahl.The connection between the elect rode space 6 and the venturi-like space 5 is made via a main Connecting channel 7 and via connecting channels 4, which are provided in an even number, that is to say not in an odd number, but rather in a number that can be divided by two.

Bei der Ausführungsform gemäß Fig. 3 sind diese Verbindung skanä le 4a über Einschnitte 8 mit dem Hauptverbindungskanal 7 a verbunden. Diese Einschnitte 8 teilen die ringförmige Massenelektrode in ebensoviel Teile, wie Verbindungskanäle 4a vorgesehen sind. Somit erhalten die Verbindungskanäle 4a die Eigenschaft resoni e render Höhlen oder Kammern oder Hohlräume. Zwei aufeinanderfolgende Räume oszillieren bei Zündung in in Opposition stehenden Phasen. In the embodiment according to FIG. 3, these connection channels 4a are connected to the main connection channel 7a via incisions 8. These incisions 8 divide the annular mass electrode into as many parts as there are connecting channels 4a. The connecting channels 4a thus have the property of resoni e render caves or chambers or cavities. Two successive rooms oscillate in ignition in opposing phases.
