Definitions

  • 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 via an even number of connecting channels to a space which faces the cylinder space of the internal combustion engine.
  • a device of the generic type is described in US-A-20 08 298.
  • an electrode is arranged in an electrode space, which is connected via connecting channels to a chamber which tapers in the direction of the cylinder space.
  • the chamber has a passage opening to the cylinder space, a passage being created through this passage opening and the chamber with the connecting channels to the electrode space, which prevents oil or pollutants from entering the electrode space.
  • this chamber which has the passage opening to the cylinder space of the internal combustion engine, is intended to serve as a buffer chamber which creates a cushion of inert gases during the compression stroke, as a result of which combustion gases cannot reach the electrode chamber and the ignition electrode.
  • a spark plug described in DE-C-661 768 has a space surrounding the electrode area, 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 scatter or flame after the mixture has ignited 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 invention is based on the object to improve the spark plugs belonging to the prior art in such a way that higher densities can be achieved without the ignition spark extinguishing.
  • the space has the shape of a half ellipsoid of revolution that widens towards the cylinder space and that the electrode space is connected to the space via a main connecting channel and the even number of connecting channels are connected to the main connecting channel via incisions .
  • the ring-shaped ground 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.
  • Fig. 1, 1 generally designates a spark plug, which is fixed by means of a fastening thread 2, 3 designating the actual spark plug body.
  • an electrode space 6 is formed, which is connected via connection channels 4 to a space 5 adjoining the cylinder space, the latter space 5, as can be seen more clearly from FIG. 2, in the form of a half ellipsoid of revolution.
  • connection of the electrode space 6 to the space 5 takes place via a main connection channel 7 and via the named connection channels 4, which are provided in an even number, i. H. that is, in a number that can be divided by two.
  • connection channels 4 are connected to the main connection channel 7 via incisions 8. These incisions divide the ring-shaped ground electrode into as many parts as connecting channels 4 are provided.
  • the connecting channels 4 thus acquire the property of resonating caves or chambers or cavities. Two successive rooms oscillate when the ignition is in opposite phases.
