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.
Claims11
A spark plug for an internal combustion engine, comprising
- a center electrode;
- a ground electrode arranged in radial direction around the center electrode;
- and
- an annular spark gap is formed between the center electrode and the ground electrode for igniting a fuel mixture by an electric ignition spark between the center electrode and the ground electrode,
- wherein the ground electrode is contoured such that particles reaching a region of the ground electrode can be removed from the annular spark gap under an influence of gravitational force.
An internal combustion engine, configured to burn a fuel mixture comprising gaseous fuel and air, having at least one spark plug comprising
- 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 the fuel mixture by an electric ignition spark developing between the center electrode and the ground electrode, and
- wherein the ground electrode is contoured such that particles reaching a region of the ground electrode can be removed from the annular spark gap under an influence of gravitational force.
