| 发明名称 | Corona ignition device | ||
| 摘要 | The invention relates to a corona ignition device for igniting fuel in an internal combustion engine by means of a corona discharge, comprising a central electrode, an insulator, into which the central electrode plugs, a housing, into which the insulator plugs, a bobbin, onto which a coil which is attached to the central electrode is wound, and a shield cap, which is plugged onto an end portion of the bobbin facing the insulator. According to the invention, a portion of the central electrode protrudes through a bottom of the shield cap, or a circumferential wall of the shield cap has one or more slots, or the shield cap has a circumferential wall, which protrudes only on one side beyond the bottom of the shield cap only on one side. | ||

| 主权项 | 1. A corona ignition device for igniting fuel in an internal combustion engine by means of a corona discharge, comprising: a central electrode; an insulator from which the central electrode protrudes; a housing which is closed at one end by the insulator, a bobbin onto which a coil is wound which is electrically connected to the central electrode; a shield cap enclosed by the housing, an end portion of the bobbin being inserted into the shield cap, said end portion facing the insulator; and wherein a portion of the central electrode protrudes through a bottom of the shield cap and wherein the shield cap is an electrical conductor and is at least partially formed from metal. | ||
