摘要： A corona ignition assembly comprising a plurality of different insulators disposed between an ignition coil assembly and firing end assembly is provided. A high voltage center electrode extends longitudinally between an igniter central electrode and the ignition coil assembly. A high voltage insulator formed of a fluoropolymer surrounds the high voltage center electrode, and a firing end insulator formed of alumina surrounds the igniter central electrode. According to one embodiment, a glue formed of a compliant and insulating material, such as a silicon-based material, forms a seal between the high voltage insulator and the firing end insulator. According to another embodiment, a dielectric compliant insulator is disposed between the high voltage insulator and the ignition coil assembly, and the glue forms a seal therebetween. The glue fills air gaps to prevent unwanted corona discharge, and thus extends the life of the materials and directs energy to the firing end.
