Retrofits in candle of ignicao and process to produce a noise suppressor element of ignicao

摘要

An improved resistance element for suppressing random radio frequency radiation from the high voltage ignition circuit of an internal combustion engine. The resistance element is produced by sintering an extruded or compressed rod consisting essentially of copper oxides plus a heat destructible binder and from 0 to 10 percent of an inert plasticizer. The resulting element consists essentially of a combination of cupric oxide (CuO) and cuprous oxide (Cu2). Optional contact terminals may be formed on the element by applying a metallic coating to opposed ends of the capsule. The suppression element may be placed in the center electrode assembly of a spark plug electrically in series between a high voltage terminal and an electrode tip or at any suitable location in the high voltage ignition circuit for the internal combustion engine.
