    摘要: A corona igniter 20 includes an electrode gap 28 between the central electrode 22 and the insulator 32 and a shell gap 30 between the insulator 32 and the shell 36. An electrically conductive coating 40 is disposed on the insulator 32 along the gaps 28, 30 to prevent corona discharge 24 in the gaps 28, 30 and to concentrate the energy at a firing tip 58 of the central electrode 22. The electrically conductive coating 40 is disposed on an insulator inner surface 64 and is spaced radially from the electrode 22. The electrically conductive coating 40 is also disposed on the insulator outer surface 72 and is spaced radially from the shell 36. During operation of the igniter 20, the electrically conductive coating 40 provides a reduced voltage drop across the gaps 28, 30 and a reduced electric field spike at the gaps 28, 30.

    摘要: A corona ignition system 20 includes a corona drive circuit 26 and an auxiliary energy circuit 28. The energy circuit 28 stores energy during a standard corona ignition cycle. When arc discharge occurs or corona discharge switches to an arc discharge, the energy circuit 28 discharges the stored energy to the electrode 30 to intentionally maintain a robust arc discharge 29 and thus provide reliable ignition. The stored energy is transmitted to the electrode 30 over a predetermined period of time. The arc discharge is detected and an arc control signal 60 is transmitted to the energy circuit 28, triggering discharge of the stored energy to the electrode 30. The stored energy can be transmitted to the electrode 30 along a variety of different paths. The voltage of the stored energy is typically increased by an energy transformer 70 before being transmitted to the electrode 30.

    摘要: A corona igniter 20 includes an electrode gap 28 between the central electrode 22 and the insulator 32 and a shell gap 30 between the insulator 32 and the shell 36. The gaps 28, 30 are filled with a filler material 40 to prevent corona discharge 24 in the gaps 28, 30 and to concentrate the energy at a firing tip 58 of the central electrode 22. The filler material 40 may be electrically insulating or conductive. The shell gap width ws may be greatest at a shell lower end 92. The shell gap 30 may also be in a turnover region between a shell upper end 44 and the insulator 32, in which case the filler material 40 is injection molded around the turnover region. During operation of the igniter 20, the filler material 40 provides a reduced voltage drop across the gap 28, 30.

    摘要: A corona igniter (20) for emitting a radio frequency electric field and providing a corona discharge (24) includes a central electrode (22) at a positive voltage, a grounded metal shell (30), and an insulator (28) with an abruption (34) extending radially outward relative to the central electrode (22). The abruption (34) is typically an increase of at least 15% of a local thickness (t) of the insulator (28) over less than 25% of a nose length (1) of an insulator nose region (74). The abruption (34) is typically one flank (82) of a protrusion or a notch, and the flank (82) faces the shell (30). The abruption (34) reverses the electric field and voltage potential gradient along the insulator outer surface (32), repels charged ions away from the insulator (28), and thus prevents the formation of a conductive path between the central electrode (22) and the shell (22).

    摘要: An electrode for an ignition device formed from a dilute nickel alloy with improved resistance to high temperature oxidation, sulfidation, corrosive wear, deformation and fracture. The electrode includes at least 90% by weight of nickel; zirconium; boron and at least one element from the group consisting of aluminum, magnesium, silicon, chromium, titanium and manganese. The weight ratio of Zr/B may range from about 0.5 to 150, and may include amounts of, by weight of the alloy, 0.05-0.5% zirconium and 0.001-0.01% boron. The oxidation resistance may be improved by the addition of hafnium in an amount that is comparable to the amount of zirconium, which may include an amount of, by weight of the alloy, 0.005-0.2% hafnium. Electrodes of dilute nickel alloys which include aluminum and silicon, as well as those which include chromium, silicon, manganese and titanium, are particularly useful as spark plug electrodes.
