Spark plug with self-diagnosis and high voltage cable for self-diagnosis of a spark plug and method for self-diagnosis of a spark plug

摘要

Spark plug (1) for an internal combustion engine, in particular a gas engine, comprising a housing (2), at least one earth electrode (5) arranged on the housing (2), an insulator (3) arranged in the housing (2), one in the insulator (3) arranged center electrode (4) which forms a Zündspalt together with the at least one ground electrode (5), a partially in the insulator (3) arranged high voltage terminal (6) via a in the insulator (3) arranged resistive element (7) with the center electrode ( 4) is electrically connected, wherein the spark plug (1) comprises an ignition voltage detector (10) for measuring an ignition voltage required for generating a Zünd.Oder Hochspannungskabel (60) for electrically contacting a Zündspannungsquelle (61) with a spark plug (1), comprising a first A terminal for electrically connecting to the ignition voltage source and a second terminal (62) for electrically connecting to the spark plug (1), wherein the high voltage cable (60) has an ignition voltage detector (10) for measuring an ignition voltage required for generating a spark.
