| 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 an insulator, which has a continuous channel, a central electrode, which plugs into the channel of the insulator and leads to at least one ignition tip, a glass seal, which seals in the channel a gap between the central electrode and the insulator, and a housing, into which the insulator plugs. In accordance with the invention, the central electrode has a sealing face, which, together with a sealing face of the insulator, forms a seat, and an annular air gap that is open towards the ignition tip is provided in an end portion of the channel, facing the ignition tip, between the central electrode and the insulator. | ||

| 主权项 | 1. A corona ignition device for igniting fuel in a combustion chamber of an engine by means of a corona discharge, comprising: an insulator, which has a continuous channel; a central electrode, which is disposed in the continuous channel of the insulator and leads to at least one ignition tip; a glass seal, which seals the continuous channel; and a housing in which the insulator is disposed, wherein the central electrode has a sealing face, which, together with a sealing face of the insulator, forms a seat; an annular air gap between the central electrode and the insulator, said annular air gap being open towards the ignition tip in an end portion of the continuous channel, said end portion facing the ignition tip; and wherein an end portion of the insulator facing the ignition tip protrudes from the housing and the sealing face of the insulator is disposed on the end portion of the insulator. | ||
