Definitions

  • the electrodes are tip-shaped (Fig. 1 item 4 + 5, Fig. 2 item 5 + 6, Fig. 3 item 5 + 6).
  • 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.
  • 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.
  • Spark plug with tip-shaped electrode is size. Shape and material as with conventional spark plugs.
