Abstract
In an ignition electrode arrangement for a cylinder in an internal combustion engine, for example an Otto engine, a cylinder head (3) bears a first electrode (7) and a second electrode (8) which interact with one another. At least the first electrode (7) is arranged on an ignition means (6) fastened in the cylinder head. According to the invention, the second electrode (8) is movable relative to the cylinder head (3) and the first electrode (7) in order to make it possible to change the spark gap. The second electrode (8) can be mounted on the cylinder head (3) itself or on the ignition device (6). The size of the spark gap is controlled during operation by the ignition system of the engine.
