Patent number: 10622788Abstract: A corona ignition assembly including a firing end assembly and an ignition coil assembly connected by a high voltage connection is provided. The high voltage connection includes a high voltage insulator formed of silicon rubber. A shield formed of metal surrounds the high voltage insulator. The high voltage connection also includes an upper insert formed of metal connecting the shield to the ignition coil assembly and a lower insert formed of metal connecting the shield to the firing end assembly. First portions of the outer surface of the high voltage insulator adhere to the shield, the upper insert, and the lower insert, while second portions of the outer surface do not adhere to at least one of the shield, the upper insert, and the lower insert. A metal braid can be embedded in the high voltage insulator.Type: GrantFiled: December 13, 2018Date of Patent: April 14, 2020Assignee: Tenneco lnc.Inventors: Kristapher I.

Patent number: 10418786Abstract: A corona igniter assembly 20 comprises an ignition coil assembly 22, a firing end assembly 24, and a metal tube 26 connecting the ignition coil assembly 22 to the firing end assembly 24. A rubber boot 28 is disposed in the metal tube 26 and compressed symmetrically between a coil output member 30 of the ignition coil assembly 22 and an insulator 42 of the firing end assembly 24. Thus, the rubber boot 28 fills any air gaps and provides a hermetic seal between the ignition coil assembly 22 and the firing end assembly 24 to prevent unwanted corona discharge from forming from those air gaps.Type: GrantFiled: June 27, 2018Date of Patent: September 17, 2019Assignee: Federal-Mogul Ignition LLCInventors: Vittorio Urciuoli, Giulio Milan, Massimo Augusto Dal Re, Paolo Pignatti

Patent number: 10008831Abstract: 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.Type: GrantFiled: March 22, 2016Date of Patent: June 26, 2018Assignee: Federal-Mogul LLCInventors: Christian Sforzina, Stefano Papi, Massimo Augusto Dal Re, Giulio Milan
