Force field anti-noise-induction system

Abstract

An electrical ignition system for a fuel buring engine has a high voltage ignition cable (60) that includes an electrically conductive shield (64) circumjacent an electrical axial conductor (62). An AC or DC power source (70, 70a, 70b) is connected to the electrically conductive shield to produce an electromagnetic force field surrounding the electrical axial conductor. Such field retains electromagnetic radiation emanated by the electrical axial conductor during ignition of the igniter (10) within the confines of the shield (64). Igniter (10) may have a ceramic insulator (30) with a synthetic resin polymer sleeve (50) covering a portion of the ceramic insulator, or insulator (30) may be made entirely of the synthetic resin polymer material to suppress corona generated by current flowing through the axial electrode (40) of the igniter during each ignition period.
