A method for producing a spark plug including a spark plug electrode assembly having a center electrode and a ground electrode surrounding the center electrode. The spark plug electrode assembly is formed from a one-piece spark plug electrode base body made of spark plug electrode material, and the ground electrode and the center electrode are connected to one another by a connecting region, wherein the center electrode and an inner surface of the ground electrode are polygonal. The method includes: a) connecting the spark plug electrode assembly to a spark plug base body, and b) removing the connecting region between the ground electrode and the center electrode.

The invention relates to a method for operating an internal combustion engine with fuel which is combusted using a spark plug. According to the invention, the aging of the spark plug, in particular the aging of an electric resistor of the spark plug, is monitored during the operation of the internal combustion engine, wherein electromagnetic radiation of the spark plug is detected for monitoring purposes. The invention additionally relates to a controller for carrying out the method.
