Distributors & Ignition Systems - DUCELLIER Electronic Ignition: Description
The Ducellier electronic ignition system consists of a Ducellier breakerless distributor, a Delco-Remy ignition coil, an electronic control unit, ignition switch and necessary wiring.
The distributor contains both centrifugal and vacuum advance mechanisms, main and secondary impulse sender coils (pick-up coils), a trigger (reluctor), seal, rotor and cap. See Fig 1.
The ignition coil and electronic control unit are mounted to a common support that provides both good grounding and cooling of the electronic control unit. See Fig 2. Silicone grease, which comes with each electronic control unit, is applied between the unit and support to provide improved heat transfer. Since both units are grounded through the common support base, all mounting bolts should be snug.
The ignition coil is encased in epoxy resin instead of oil. The electronic control unit receives, amplifies and sends electronic signals to provide proper spark timing.
