| 摘要 |
<p>The present invention relates to a spark plug (1) comprising a central electrode (3) extending along a longitudinal axis (2) of the spark plug (1) and having at least one first spark face (6), and a ground electrode (4) having at least one second spark face (8), wherein the first spark face (6) is arranged opposite the second spark face (8), with the result that an ignition spark can be generated between the first spark face (6) and the second spark face (8), wherein the central electrode (3) is rotatable with respect to the ground electrode (4) coaxially to the longitudinal axis (2), and/or the ground electrode (4) is rotatable with respect to the central electrode (3) coaxially to the longitudinal axis (2), and wherein the first spark face (6) and the second spark face (7) are inclined in such a way that, by rotation of the central electrode (3) with respect to the ground electrode (4) and/or of the ground electrode (4) with respect to the central electrode (3), a distance (18) between the first spark face (6) and the second spark face (8) is adjustable.</p> |
