Abstract
A spark plug for a gas-powered internal combustion engine having: a spark plug body; an insulator; a center electrode; a ground electrode support that is attached to the spark plug body and supports at least one ground electrode that forms a spark gap with the center electrode; a swirl chamber located at the front end of the spark plug whose wall surrounds the center and ground electrodes; the wall of the swirl chamber is formed by a cylindrical sleeve which has an open front face and radial perforations; the ground electrode support includes an annular base part and at least one arm that supports the ground electrode; the arm starts at the base part and extends within the swirl chamber. The arm of the ground electrode support increases in cross-section starting from the ground electrode it supports toward the annular base part of the ground electrode support.
