Abstract
A corona igniter () comprises a central electrode () surrounded by an insulator (), which is surrounded by a metal shell (). A ceramic combustion seal () is disposed along the gap () between a shell lower end shell () and the insulator nose region () to provide a hermetic seal therebetween. The ceramic combustion seal () is typically a bushing, cylinder, or ring formed of sintered alumina. A glass material or glass/ceramic mixture () typically adheres the ceramic combustion seal () to the shell () and the insulator (). Alternatively, the ceramic combustion seal () is brazed to the shell (), and the glass material or glass/ceramic mixture () adheres the ceramic combustion seal () to the insulator ().
