Definitions

  • the present invention relates to a spark plug for an internal combustion engine, two or four times.
  • US1929748 A which is considered to represent the closest state of the art, represents an extremely “hot” spark plug to judge by the size of the "chamber” (20, fig.3 This was normal for engines of the 1930s (4 to 5 volumetric rate, side valves and excessive consumption of oil, etc .). To manufacture a spark plug meeting the current thermal indices (8.5 to 12 volumetric rate) according to this patent, it would be necessary to reduce the "chamber” (20, fig.3 ), see the disappear. So its main claim to make holes in a spin (21) to shoot flames from the "chamber” through them, to better ignite the gas mixture, is no longer possible.
  • the patent : FR2841396 only provides a device for guiding the gas mixture to the negative electrode, but the device can not avoid the deposition of calamine on the candle.
  • the two orifices and the projection in a spin weaken the negative electrode due to its small section.
  • a traditional candle keeps the gaseous mixture inside the base, and at the moment of the explosion the deposit of calamine fouls the candle, and with time degrades its yield.
  • the spark occurs only on a part of the electrode surfaces, so a low intensity spark.
  • the heat of operation of a traditional candle is very important and lowers its performance.
  • a spark plug according to claim 1.It has in fact, according to a first characteristic, oblique holes in the form of venturi, passing through the base of the base. These make it possible to create a circulation of the gaseous mixture inside the base, to increase the density of the gaseous mixture with the spark, thus avoiding the deposition of scale, and decreasing the heat of operation of the spark plug (as a thermal index regulator).
  • the device according to the invention comprises a second characteristic, a hole, conical on its upper part, passing through the negative electrode, which acts as an electrical "vacuum", making it possible to create a counter pressure to improve the density of the gas mixture before the spark, and get a more homogeneous spark, wider, more intense, and through the hole to create a flame front to allow to burn the gas mixture further into the cylinder.
  • the device comprises several oblique holes (1) running through the base of the base (2) ( fig.2 , fig.4 ), and a hole (3) passing through the negative electrode, conical on its upper part, of the candle (6) ( Fig. 2 , Fig. 3 , fig.4 ), its seat (7) can be flat or conical.

  1. Eine Zündkerze für Motoren mit interner Verbrennung, mit einem Sitz (7) und einer negativen Elektrode mit einem unteren Teil, der mit dem Sockel verbunden ist und einem oberen Teil, bei welcher der Sockel von schräg verlaufenden Bohrungen durchsetzt ist, dadurch gekennzeichnet, dass die genannten Bohrungen eine Venturiform besitzen und es ermöglichen, die Gasmischung im Innern des Sockels (2) in Bewegung zu versetzen und den Wärmewert nach dem Aufwärmen des Motors zu kontrollieren, und dass der obere Teil der negativen Elektrode eine konische ausgebildete, durchgehende Bohrung (5) besitzt, welche zur Bildung eines gleichmäßigeren und stärkeren Funkens und, durch die Bohrung hindurch, zur Entstehung einer Flammenfront führt, um die Gasmischung weiter entfernt im Zylinder zu verbrennen.
  2. Zündkerze gemäß Patentanspruch 1, gekennzeichnet dadurch, dass der Sitz (7) eben oder kegelförmig sein kann.
