Abstract: A prechamber ignition apparatus for an internal combustion engine includes a prechamber and a spark plug. The prechamber has a plurality of overflow openings via which the prechamber can be fluidically connected to a combustion chamber of the internal combustion engine. At least part of a mixture comprising fuel and air can be introduced into the prechamber from the combustion chamber. The spark plug has an ignition electrode by which at least one ignition spark can be produced in the prechamber between the ignition electrode and a corresponding ground electrode in order to ignite a part which is introduced into the prechamber via the overflow openings. The ground electrode and the spark plug having the ignition electrode are formed as structurally separated components.
