Abstract
A corona igniter () comprises a central electrode () surrounded by an insulator (), which is surrounded by a conductive component. The conductive component includes a shell () and an intermediate part () both formed of an electrically conductive material. An outer surface () of the insulator () presents a lower ledge (), and the intermediate part () is typically attached to the insulator () above the lower ledge () prior to inserting the insulator () into the shell (). The conductive inner diameter (D) is less than an insulator outer diameter (D) directly below the lower ledge () such the insulator thickness (t) increases toward the electrode firing end (). The corona igniter () can be reversed-assembled by inserting an upper end () of the insulator into a firing end () of the shell.
