Ignition method and igniter device for igniting carburated gaseous mixtures

摘要

A flash-spark creeps on a dielectric surface to ignite carburated gaseous mixtures. A high voltage pulse is applied through the dielectric between opposite surfaces thereof. The voltage is applied between a first electrode having a smaller area abutting against a first surface of the dielectric and a second electrode having a first strip portion abutting against an opposite second surface of the dielectric and a second portion which is astride an edge of the dielectric. The strip portion ends at a position beneath the first electrode. The first surface is exposed to the carburated gaseous mixture.
