Definitions

  • the object underlying the invention is therefore to design the spark plug according to the preamble of claim 1 so that it has a relatively low voltage requirement with high energy conversion in the ignitable fuel-air mixture.
  • spark plug is operated with an ignition system with a very steep voltage increase of, for example, 3 kV per ns and a potential energy of ⁇ 30 mJ, then multiple spark channels are formed in all load states, since a plasma channel alone cannot carry the large currents.
