NIPPONDENSO Electronic Ignition System: Description
Nippondenso electronic ignition system includes a breakerless distributor, an ignitor (ignition control unit), a special ignition coil, an ignition signal generating mechanism (pick-up coil assembly) and ignition switch.
The distributor consists of a housing, rotor and cap. It contains a timing rotor (reluctor), magnet, and pick-up coil assembly. A transistorized ignitor is separate from the distributor. See Fig 1. Distributors contain conventional centrifugal and vacuum advance mechanisms.
