  • Distributor electrode assembly having outer resistive layer for suppressing noise
    Patent number: 4091245
    Abstract: A distributor for the ignition system of an internal combustion engine wherein the rotor and/or stationary terminals of the distributor are a brass or steel substrate bearing an intermediate layer of nickel aluminide and a further layer of electrically high resistive material, the resultant distributor exhibiting significantly suppressed noise emission.
    Type: Grant
    Filed: July 6, 1976
    Date of Patent: May 23, 1978
    Assignee: Toyota Jidosha Kogyo Kabushiki Kaisha
    Inventors: Yoshiro Komiyama, Katsumi Kondo, Yoichiro Asano, Mituo Ando
  • Method for surface treatment of electrode in distributor of internal combustion engine for suppressing noise
    Patent number: 3992230
    Abstract: Using a plasma arc coating process or a thermospraying process or a detonation process an electrode of a rotor of a distributor for the ignition system of an internal combustion engine was surface treated to provide the electrode with a surface layer of an electrically high resistive material, e.g. CuO. A distributor having the treated rotor included therein exhibited significantly suppressed noise. Instead of or in addition to the rotor, each of the stationary terminals of the distributor may be so treated.
