ABSTRACT:
A spark plug with an insulating body held in a casing and containing an inner electrode is provided with a force-measuring element for measuring the pressure acting on the spark plug, the insulating body resting against the casing via the force-measuring element when pressure is applied in an axial direction. To prevent the entrance of noise signals an axially-elastic sealing element is provided on a side adjacent to the combustion space, the sealing element additionally lending radial support to the insulating body resting against the casing of the spark plug.
