ABSTRACT:
A variable impedance device which serves to improve performance and reduce radio frequency emissions in electrically fired internal combustion engines employs a mixture of granulated or powdered bronze, or the constituents of bronze and of silica compacted and continually compressed for connection in series with the ignition wiring of an engine. The proportions of metal and silica are such that an irregular but complete conductive pathway is formed through the mixture. In preferred form the powders or granules are compressed within a fused silica lined sheath of stainless steel.
