Title: Ignition distributor for internal combustion engines

Abstract

A distributor is described comprising: fixed electrodes adapted to be electrically connected to sparking plugs of an internal combustion engine, and a rotating electrode adapted to be rotatable in synchronism with a crank of the internal combustion engine and forming a narrow gap sequentially with each of the fixed electrodes. It is featured that at least one of the electrodes and the rotating electrode is made of a ceramic that has the function of a varistor and has as a main material at least one of zinc oxide (ZnO) and nickel oxide (NiO) and as an additive at least one of bismuth oxide (Bi/sub 2/O/sub 3/), manganese dioxide (MnO/sub 2/) and cobalt oxide (CoO), which are sintered together.
