In an ignition electrode arrangement at a cylinder in an internal combustion engine, for example an Otto-engine, a first electrode and a second electrode co-operate with each other, the first electrode being arranged on an ignition device secured to a cylinder head. Both electrodes are movable in order to enable a change in the size of the spark gap and/or the position of the spark gap. The electrodes are each manipulated by an operating device that is controlled by a control unit included in the ignition system of the engine.
