Ignition distributor for an internal combustion engine

摘要

An ignition distributor for an internal combustion engine comprises a cylindrical distributor rotor of synthetic resin that rotated synchronously with the revolution of the engine, a rotor electrode radially and outwardly extending from the central portion on an upper surface of the rotor, a plurality of circumferential electrodes disposed in the rotating locus of said rotor and separated from said rotor electrode by a discharge gap, a contact electrode contacting said rotor electrode, a rotation angle sensor, and a signal processing unit for processing output signal from the rotation angle sensor. The signal processing unit is arranged coaxially with and below the distributor rotor, and is provided with a shield cover which is earthed.
