ABSTRACT:
A device is disclosed which detects the knocking phenomena in a controlled-ignition internal combustion engine, the device essentially comprising two ionization probes arranged in a zone of the explosion chamber remote from the sparking plug: the probes deliver signals when the state of ionization changes and the time interval between the signals of the two probes is measured and compared with an appropriate reference value.
