摘要：
The invention concerns a device for measuring an ionization current of a spark plug of the type with resonant structure, equipping a motor vehicle ignition system, said spark plug (BR) being coupled to a generator (GEN) comprising a regulating capacitor. Said generator further comprises polarizing means (MPOL) for polarizing the spark plug (BR), connected between the generator (GEN) and said spark plug (BR) and means for measuring (MMES) the ionization current of said spark plug (BR), connected between the regulating capacitor (Cb) and the ground.
