Abstract (en)

[origin: FR2899394A1] The method involves charging a resonant structure spark plug (BR) by a voltage generated with respect to a charged ballast capacitor (Cb) during ignition phase. Ionization current (Ii) of the spark plug is periodically measured between two ignition phases by a measurement unit (MMES), where the ionization current is measured between the ballast capacitor and a weight after polarizing the spark plug. An independent claim is also included for a device for measuring ionization current of a resonant structure type spark plug.
