- a particularly favorable method for producing a spark plug according to the above mentioned features provides that the wall of the swirl chamber with at least a ground electrode and / or at least one ground electrode carrier and / or with at least one ground electrode support arrangement and / or the Center electrode carrier manufactured individually and then on commercially available Spark plugs can be attached.
- This method according to the invention makes it possible thus, inexpensive standard industrial spark plugs as they are commercially available from various spark plug manufacturers are offered to use. Because of this A spark plug according to the invention can be produced from a very large number of methods various standard industrial spark plug types. Furthermore it is possible to manufacture a large number of different spark plugs at low cost.
- the wall of the swirl chamber on at least one ground electrode of a commercially available spark plug pulsed and / or continuously working laser welding process and / or Electrode beam welding process and / or soldering process and / or Resistance welding process is welded on.
- the central electrode carrier on at least one base central electrode of the Insulator body of a standard commercial spark plug using pulsed and / or continuously working laser welding process and / or Electrode beam welding process and / or soldering process and / or Resistance welding process is welded on.
- a swirl chamber 3 is attached to the lower housing part 4 on the motor side whose combustion chamber end 15 is open.
- Other alternatives can also be used Nickel-based alloys or high-temperature stainless steels for the wall 13 for Come into play.
- the vortex chamber 3 is alternatively also in one piece as integrating part of the lower housing part 4 manufactured.
- the wall 13 of the swirl chamber 3 has openings 2 which are good Allow mixture access.
- the openings 2 can be bores, slots, Polygons or ellipses or similar form can be executed.
- the swirl chamber 3 and the ground electrode carrier 6 can be made in one piece. However, it is also possible to use rectangular ones To weld metal cuboid 5 as a ground electrode support 6 in the swirl chamber (Fig. 3). This can also be done by welding one Ground electrode support arrangement 8 take place. This is in Fig. 4 as an annular Arrangement 8 shown.
- the wall 13 of the swirl chamber 3 can be a or more exemption (s) 12, making it possible to Readjust the ground electrode carrier 6 or the ground electrode carrier arrangement 8 (Fig. 5).
- the ground electrode carriers 6 are with noble metal platelets as ground electrodes 9 provided, these are lasered on one or both sides with the carrier 6 welded. The weld is attached so that on the electrode sides of the Gap is closed. That is, between precious metal platelets 9 and There is no open gap (or opening) through which gas ground electrode carrier 6 can occur.
- the ground electrodes 9 come in the illustrated embodiment Precious metal plate with the dimensions 6.25 x 1.6 x 0.5 mm (it can also other dimensions are used).
