Distributor: Description and Operation

DIGIFANT II




Ignition Distributor

The ignition distributor has no centrifugal or vacuum advance. It contains a Hall sender which is operated by a trigger wheel. The trigger wheel has four apertures, one for each cylinder.

The Hall sender sends a voltage signal to the E.C.U. for each cylinder. From this signal, the control unit determines engine speed and crankshaft position.
