TENDSPENNINGSFORDELARE FOR FORBRENNINGESMOTOR

摘要

A distributor for distributing high-voltage pulses generated by an ignition coil to individual ignition plugs through a center electrode, a rotor electrode and a plurality of side electrodes disposed opposite to the rotor electrode with a discharge gap defined therebetween, in which the discharge-participating area of the rotor electrode and/or each side electrode includes finely interspersed conductive regions and high-resistance regions thereby reducing the discharge voltage at the discharge gap between the rotor electrode and each side electrode for suppressing generation of radio noises. The discharge participating areas of the rotor and stationary electrodes may be formed of ferrite.
