Spark plug for a device for detecting an ionization current, without that a pulsed noise on the ion current is generated

摘要

Spark plug (703) for an ion current - detection device (10) for detecting an ionization current, of the of the spark plug (703) is generated, wherein the spark plug (703) by means of a connecting component (94) electrically with the ion current - detection device (10) and the following components can be connected has:a center electrode (33), the first and second ends;a grounding electrode (35), the the first end of the center electrode (33) for guiding a discharge gap (38) with the center electrode (33) to form the ion current in the gap (38); anda shank section (34) with a corrosion-resistant conductive layer (34b) on its exterior, which a first end face, the electrically with the second end of the center electrode (33), and a second end face (340b) having a conductive layer (34d) concerned and electrically with the connecting means (94).the conductive layer (34d) on the second end face (340b) of the shaft section (34) on the..
