Description

An unserer Erfindung Zündkerze mit spitzenförmiger Elektrode sind die Elektroden spitzenförmig (Fig. 1 Pos. 4+5, Fig. 2 Pos. 5+6, Fig. 3 Pos. 5+6). An der Spitze der Elektroden drängen sich die elektrischen Feldlinien sehr stark zusammen. Dadurch entsteht an dieser Position zwischen den Elektroden (Fig. 1 Pos. 4+5 , Fig. 2 Pos. 5+6 und Fig. 3 Pos. 5+6) ein intensives Magnetkraftfeld. Der Wirkungsgrad der Zündkerze wird wesentlich beeinflußt.In our spark plug with a tip-shaped electrode, the electrodes are tip-shaped (Fig. 1 item 4 + 5, Fig. 2 item 5 + 6, Fig. 3 item 5 + 6). At the tip of the electrodes, the electric field lines are very tight. This creates an intense magnetic force field at this position between the electrodes (Fig. 1 Pos. 4 + 5, Fig. 2 Pos. 5 + 6 and Fig. 3 Pos. 5 + 6). The efficiency of the spark plug is significantly affected.

Bei der herkömmlichen Zündkerze besteht die Oberfläche der Elektroden aus geraden und runden Flächen. Dadurch befindet sich der Funk zwischen den Elektroden immer auf einer anderen Position der Fläche. Es besteht großer Widerstand bei Motoren mit höherer Verdichtung. Mit dem Ergebnis, daß bei den herkömmlichen Zündkerzen kleinerer Elektrodenabstand dadurch entsteht und kleinerer Funk zwischen den Elektroden.In the conventional spark plug, the surface of the electrodes consists of straight and round surfaces. This means that the radio between the electrodes is always in a different position on the surface. There is great resistance in engines with higher compression. With the result that in the conventional spark plugs this results in a smaller electrode spacing and less radio between the electrodes.

Unsere Erfindung Zündkerze mit spitzenförmiger Elektrode erbringt folgende Vorteile:

  • - durchdringender Funk auch bei höherer Verdichtung
  • - bessere Zündung des Kraftstoffes (dadurch auch weniger Abgase
  • - verbesserte Motorenleistung.
Our invention spark plug with a pointed electrode provides the following advantages:
  • - penetrating radio even with higher compression
  • - better ignition of the fuel (therefore less exhaust gases
  • - improved engine performance.

Zündkerzen mit spitzenförmiger Elektrode (Fig. 2 Pos. 6+5) wurden in ein KFZ-Motor eingebaut und über 8000 km getestet. Der Versuch erbrachte untenstehende Ergebnisse:

  • - der Motor läuft gleichmäßiger
  • - es entstehen kaum Fehlzündungen und AUsstoß von unverbrannten Kraftstoff
  • - als Folge läuft das KFZ schadstoffärmer
Spark plugs with a pointed electrode (Fig. 2 Pos. 6 + 5) were installed in a motor vehicle engine and tested over 8000 km. The experiment gave the following results:
  • - the engine runs more smoothly
  • - There are hardly any misfires and unburned fuel emissions
  • - As a result, the car runs with fewer pollutants

Bei der Untersuchung dieser Zündkerze (Fig. 2,Pos. 6+5, Fig. 3 Pos. 6+5) ist festzustellen, daß

  • 1. ein Verschleiß der Spitze der Elektrode (Fig. 2 Pos. 6+5, Fig. 3 Pos. 6+5) nich erkennbar ist.
  • 2. nur über ein Vergrößerungsglas (mit blosem Auge kaum erkenntlich) sieht man unter der Spitze der mittleren Elektrode eine Mulde (Fig. 3, Pos. 7). Das bedeutet eine exakte Funktion der Führung des Funkes von einer Elektrode zur anderen. Außerdem weist diese Mulde (Fig. 3, Pos. 7) auf a lange Lebensdauer der Zündkerze hin b der Wirkungsgrad der Spitze bleibt konstant
  • 3. Der Isolator der mittleren Elektrode (Porzellan) (Fig. 2, Pos. 1+3, Fig. 3 Pos. 1+3) ist frei von. Rückständen
When examining this spark plug (Fig. 2, Pos. 6 + 5, Fig. 3 Pos. 6 + 5) it is found that
  • 1. Wear of the tip of the electrode (Fig. 2 Pos. 6 + 5, Fig. 3 Pos. 6 + 5) is not recognizable.
  • 2. Only through a magnifying glass (barely visible to the naked eye) can a trough be seen under the tip of the middle electrode (Fig. 3, item 7). This means an exact function of guiding the spark from one electrode to another. In addition, this trough (Fig. 3, Item 7) indicates a long service life of the spark plug b the efficiency of the tip remains constant
  • 3. The insulator of the middle electrode (porcelain) (Fig. 2, Pos. 1 + 3, Fig. 3 Pos. 1 + 3) is free of. Residues

Bei unserer Erfindung. Zündkerze mitspitzenförmiger Elektrode ist Größe. Form und Material wie bei den herkömmlichen Zündkerzen.With our invention. Spark plug with tip-shaped electrode is size. Shape and material as with conventional spark plugs.

1. Zündkerze mit spitzenförmiger Elektrode Unsere Erfindung wird dadurch gekennzeichnet,daß die Elektroden der ZOndkerze spitzenförmig sind (Fig. 1 Pos. 4+5 und Fig. 2 Pos. 6+5). An der Spitze der Elektroden drängen sich die elektrischen Feldlinien sehr stark zusammen, dadurch entsteht an dieser Position zwischen den Elektroden (Fig. 1 Pos. 4+5 und Fig. 2 Pos. 5+6) ein intensives Magnetkraftfeld, und auf diese Wirkung der Spitze wird der Wirkungsgrad der Zündkerze wesentlich verbessert.1. Spark plug with a pointed electrode Our invention is characterized in that the electrodes of the spark plug are pointed (Fig. 1 item 4 + 5 and Fig. 2 item 6 + 5).
