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 (el) 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： A corona igniter 20 includes an insulator 28 surrounding a central electrode 24 and a shell 30 surrounding the insulator 28. The shell 30 presents a shell gap 38 having a shell gap width ws between a shell lower end 34 and a shell inner surface 90 or shell outer surface 92. The shell 30 has a shell thickness ts decreasing toward the shell lower end 34 allowing the shell gap width ws to increase toward the shell lower end 34. The shell gap 38 is open at the shell lower end 34 allowing air to flow therein, and the shell gap width ws is greatest at the shell lower end 34. The increasing shell gap width ws enhances corona discharge 22 along the insulator 28 between the central electrode 24 and shell 30.

摘要： An igniter (20) of a corona ignition system emits a non-thermal plasma in the form of a corona (30) to ionize and ignite a fuel mixture. The igniter (20) includes an electrode (32) and a ceramic insulator (22) surrounding the electrode (32). The insulator (22) surrounds a firing end (38) of the electrode (32) and blocks the electrode (32) from exposure to the combustion chamber (28). The insulator (22) presents a firing surface (56) exposed to the combustion chamber (28) and emitting the non-thermal plasma. A plurality of electrically conducting elements (24) are disposed in a matrix (26) of the ceramic material and along the firing surface (56) of the insulator (22), such as metal particles embedded in the ceramic material or holes in the ceramic material. The electrically conducting elements (24) reduce arc discharge during operation of the igniter (20) and thus improve the quality of ignition.

摘要： A spark plug (24) is used in an ignition system (10) of the type for creating a precisely timed spark to ignite an air/fuel mixture in an internal combustion engine. The spark plug (24) is provided with an integrated capacitor feature to increase the intensity of its spark. The capacitor feature is formed by applying metallic film (62, 64) to the inner (30) and outer surfaces of a tubular insulator (26). The insulator (26), made from an alumina ceramic material, forms a dielectric and sustains an electrical charge when an electrical differential is established between the inner (64) and outer (62) metallic films. The stored electrical charge is discharged with the firing of a spark in the spark gap (54). The inner (64) and outer (62) metallic films can be applied as a paint or ink directly to the surfaces of the insulator (26), or can be mixed with a glazing compound to form conductive coatings simultaneous with the glazing operation. Ganged (62′) or serpentine (62″) micro-plates can be formed within either or both of the inner and outer metallic films to increase the charge-carrying surface area. The metallic film (62, 64) is specially selected from materials that will not migrate into the porous matrix of the ceramic insulator (26). The metallic film (62, 64) is preferably gold, platinum, copper, or a platinum group metal.

摘要： A corona discharge ignition system 20 includes an igniter 22 for receiving pulses of electrical energy each having a radio frequency. The igniter 22 emits pulses of electrical field ionizing a fuel-air mixture and providing pulses of corona discharge 24, rather than a continuous, un-pulsed corona discharge over the same period of time. The system 20 includes at least one power supply 48, 50 providing the electrical energy to a corona drive circuit 52 and ultimately to the igniter 22. The system 20 can include a variable high voltage power supply 50 and a local charge storage device 70 for providing pulses of the electrical energy to the corona drive circuit 52. The system 20 provides a robust ignition comparable to a single event corona discharge ignition system, with improved resistance to arc formation, while using a fraction of the energy.

摘要： A spark plug having a multilayer firing tip that minimizes the amount of precious metal used and a method of assembling a spark plug with a multilayer firing tip. The firing tip includes a discharge end and a weld end, with the weld end being connected to a center electrode, and more specifically to a base electrode on the center electrode. The weld end has a coefficient of thermal expansion, which is not between the values for the coefficients of thermal expansion for the discharge end and the base electrode. More specifically, the weld end has a coefficient of thermal expansion which is greater than the coefficients of thermal expansion for the discharge end and base electrode. The weld end is formed from Nickel and Chromium with a limited amount of additional elements. The spark plug is assembled by providing a first elongated material formed from the material used for the discharge end and a second elongated material formed from a material used for the weld end. The two materials are then joined to form a single joined material and are severed to create a firing tip. The firing tip is welded to the center electrode of the spark plug and more specifically, the base electrode.
