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： An igniter (20) emitting an electrical field including a plurality of streamers forming a corona includes a corona enhancing tip (52) at an electrode firing end (28). The corona enhancing tip (52) includes an emitting member (58) such as a wire, layer, or sintered mass, formed of a precious metal and disposed on a base member (54). The base member (54) is formed of a nickel alloy. The emitting member (58) has a lower electrical erosion rate and chemical corrosion rate than the base member (54). The emitting member (58) presents the smallest spherical radius of the corona enhancing tip (52) at the outermost radial point (56) to concentrate the electrical field emissions and provide a consistently strong electrical field strength over time.

摘要： A spark plug, a center electrode therefore and method of construction is provided. The spark plug has a generally annular ceramic insulator extending between a terminal end and a nose end. A conductive shell surrounds at least a portion of the ceramic insulator and a ground electrode having a ground electrode sparking surface is operatively attached to the shell. An elongate center electrode has a body extending between opposite ends, wherein the body is compacted and sintered of a conductive or semi-conductive ceramic material. One of the electrode ends provides a center electrode sparking surface to provide a spark gap between the center electrode sparking surface and the ground electrode sparking surface.
