Abstract
Spark plug for an internal combustion engine, having a center electrode and a ground electrode arranged in radial direction around the center electrode, wherein an annular spark gap is formed between the center electrode and the ground electrode for igniting a fuel mixture by means of an electric ignition spark developing between the center electrode and the ground electrode, and wherein the ground electrode is contoured in such a way that particles reaching the region of the ground electrode can be removed from the spark gap under the influence of gravitational force.
