摘要:
A spark plug for an internal combustion engine includes a ground electrode, a center electrode, an insulator, a housing, and a folded packing which is situated on an outer circumference of the housing. The folded packing has: a hollow profile in cross section; a free leg directed outwards; and a support region. The folded packing lies on a contact surface in a support region, and the free leg is situated at an angle to the support region. The folded packing is pressed together during the mounting of the spark plug, and the free leg of the folded packing is designed to bend over in the direction of the support surface during the mounting to provide a diameter enlargement of the folded packing.
