摘要 |
<p>The invention relates to a spark plug of an internal combustion engine, preferably for spark-ignition gas engines, comprising a spark plug housing that surrounds an insulating body and comprising a center electrode and at least one ground electrode supported by a ground electrode carrier, wherein the ignition surface of the center electrode and the ignition surface of the ground electrode are surrounded by a wall, which forms a chamber open on the combustion chamber side. According to the invention, the ground electrode carrier, as viewed perpendicularly to the longitudinal axis (A) of the spark plug, is spaced further apart from the center electrode than the outer surface of the wall of the chamber therefrom and supports at least one finger-shaped ground electrode, which extends into the chamber through an opening in the wall, wherein the ignition surface of the ground electrode lies at the same height as the ignition surface of the center electrode in the chamber.</p> |
