Definitions
- the ignition control signal induces large currents that have an amplitude difference of more than 120 dB with the ionization current due to combustion of the fuel mixture.
- the measurement of this current occurring after the end of the ignition therefore undergoes a glare time, during which the measuring circuit can perform the acquisition of a low current.
