Knock detector extracts vibration component superimposed on ion current, controls ignition timing based on knock intensity, varies detection threshold depending on ion current information
Knock detector extracts vibration component superimposed on ion current, controls ignition timing based on knock intensity, varies detection threshold depending on ion current information
The device extracts a vibration component superimposed on an ion current generated by combustion, forming components greater than or equal to a knock detection threshold into a pulse waveform, deriving a knock intensity and controlling the ignition control time based on the knock intensity. The knock detection threshold is altered depending on ion current information
