IGNITION PLUG FOR A CYLINDER IN A COMBUSTION ENGINE

摘要

The present disclosure relates to an ignition plug for initiating combustion in a cylinder of a combustion engine, wherein the cylinder can be operated in an active mode and in a deactivated mode. The ignition plug comprises a housing that can be connected to the cylinder, an insulator is fastened to the housing and comprises an axial bore hole and a middle electrode is arranged in the axial bore hole to form an annular gap between the middle electrode and the insulator. The ignition plug comprises a sealing element that can be activated in dependence upon the mode of the cylinder so as to seal the gap preventing any seepage of oil during cylinder deactivation.
