A spark plug of an internal combustion engine, in particular for use in Otto-cycle gas engines, comprising an insulator body, a base central electrode, at least one ground electrode and at least one swirl chamber, wherein the electrodes of the spark plug are surrounded by a wall, which in particular is in the form of a surface of a cylinder, of the swirl chamber, wherein at least one ground electrode carrier arrangement () with a plurality of inwardly facing, preferably flat ground electrodes () or a plurality of ground electrode carriers () each with inwardly facing, preferably flat ground electrodes () is or are arranged at the wall () of the swirl chamber ().

Spark plug of an internal combustion engine

A spark plug, in particular for use in internal combustion engines, includes a spark plug casing and a ground electrode carrier casing. The ground electrode carrier casing has at least two ground electrode carrier casing portions having mutually different materials and/or the ground electrode carrier casing is of a different material from the spark plug casing.

Spark plug including ground elcetrode carrier casing

A spark plug is disclosed. The spark plug has a ceramic insulator body and a center electrode that is housed at least partially in a bore in the insulator body. The center electrode is sealed off from the insulator body by at least one sealing ring surrounding the center electrode that contains material that is plastically deformable by compression.

Spark plug with sealing ring around center electrode

A spark plug of an internal combustion engine, in particular for use in Otto-cycle gas engines, having an insulator body, at least one fixed ground electrode carrier arrangement and at least one fixed central electrode carrier, wherein a spark plug housing having at least two parts encloses the insulator body, wherein the spark plug housing has a lower housing portion and an upper housing portion, wherein at least the combustion chamber-side part of the insulator body is pressure-resistantly, preferably completely, enclosed by the lower housing portion jointly with the upper housing portion.
