Knock Sensor Regulation (Digifant II)

DIGIFANT II




Knock Sensor Regulation

If a cylinder develops ignition knock, the Digifant II control unit will sense this through the knock sensor mounted on the engine block. The control unit will then retard the ignition timing 3.0°for that cylinder. If the knocking stops, the ignition timing will be advanced in steps of 0.33° back to the pre-programmed value.

If the knocking continues or recurs, the ignition timing can be retarded up to 15° for each cylinder. The difference between two cylinders is limited to 9°.
