| 发明名称 | Corona ignition device | ||
| 摘要 | The invention relates to a corona ignition device for igniting fuel in a combustion chamber of an engine by means of a corona discharge, comprising a tubular housing, a coil arranged in the tubular housing, an insulator, which plugs into the tubular housing, and a center electrode, which is connected to the coil, plugs into the insulator and leads to at least one ignition tip. In order to increase the service life of the ignition tip, said ignition tip consists in part or completely of an iridium-based alloy containing 3 to 30% by weight of rhodium or is coated by a burn-up layer. | ||
