摘要： An igniter (20) includes an outer insulator (24) formed of an outer ceramic material hermetically sealed to a conductive core (26). The conductive core (26) is formed of a core ceramic material and a conductive component, such as an electrically conductive coating applied to the core ceramic material or metal particles or wires embedded in the core ceramic material. The conductive core (26) is typically sintered and disposed in the green outer insulator (24). The components are then sintered together such that the outer insulator (24) shrinks onto the conductive core (26) and the hermetic seal forms therebetween. The conductive core (26) fills the outer insulator (24), so that the conductive core (26) is disposed at an insulator nose end (34) of the outer insulator (24) and the electrical discharge (22) can be emitted from the conductive core (26), eliminating the need for a separate firing tip.

摘要： A corona igniter 20 includes a central electrode 34 for receiving a high radio frequency voltage from a power source and emitting a radio frequency electric field to ionize a fuel-air mixture and provide a corona discharge 22. The corona igniter 20 includes an insulator 38 extending along the central electrode 34 longitudinally past the central electrode 34 to an insulator firing end 40. The insulator firing surface 42 and the center axis A present an angle α of not greater than 90 degrees therebetween, for example the insulator firing surface may be concave. The central electrode 34 may also include a firing tip 50, in which case the insulator firing surface 42 surrounds all sides of the firing tip 50. The geometry of the insulator firing surface 42 concentrates and directs the corona discharge 22.

摘要： A corona igniter (20) comprises a central electrode (22) surrounded by an insulator (24), which is surrounded by a metal shell (26). A ceramic combustion seal (30) is disposed along the gap (32) between a shell lower end shell (52) and the insulator nose region (48) to provide a hermetic seal therebetween. The ceramic combustion seal (30) is typically a bushing, cylinder, or ring formed of sintered alumina. A glass material or glass/ceramic mixture (60) typically adheres the ceramic combustion seal (30) to the shell (26) and the insulator (24). Alternatively, the ceramic combustion seal (30) is brazed to the shell (26), and the glass material or glass/ceramic mixture (60) adheres the ceramic combustion seal (30) to the insulator (24).
