Abstract
A pre-chamber spark plug for a combustion chamber of an internal combustion engine has a pre-chamber which has a plurality of openings and which is fluidically connectable to the combustion chamber via the openings. Two spark gaps are arranged in the pre-chamber via which respective sparks can be formed. The spark gaps are arranged symmetrically distributed in the pre-chamber and a first of the spark gaps is arranged further outwards than the second spark gap along a direction extending perpendicularly to the longitudinal direction of the pre-chamber spark plug.
