ABSTRACT:
To reduce the breakdown potential magnitude of the distributor gap between the output tip surface of an ignition distributor rotor output segment and each of the output electrodes of the distributor cap, a layer of a thermoset silicone dielectric material is bonded to at least a portion of the surface area of the rotor output segment and is so located that the interface between the dielectric material and the metal of the rotor output segment nearest the output tip surface is no further than 0.040 inch radially inwardly from the output tip surface.
