Abstract: A corona igniter comprises an electrode with a central extended member extending along a central axis and a crown extending radially outwardly from the central extended member. The central extended member has an extended length and the crown has a crown length. The extended length is greater than the crown length such that the extended member approaches a piston more closely than the crown. In addition, the firing tips of the crown each present a first spherical radius which is less than a second spherical radius of the central extended member. Thus, if arcing occurs, it forms from the central extended member, rather than from the crown. Accordingly, the firing tips of the crown experience less wear and remain sharp. In addition, due to the sizes of the spherical radii, corona discharge is more likely to form from the firing tips than from the central extended member.

Abstract: An electrode core material that may be used in electrodes of spark plugs and other ignition devices to provide increased thermal conductivity to the electrodes. The electrode core material is a precipitate-strengthened copper alloy and includes precipitates dispersed within a copper (Cu) matrix such that the electrode core material has a multi-phase microstructure. In several exemplary embodiments, the precipitates include: particles of iron (Fe) and phosphorous, particles of beryllium, or particles of nickel and silicon.

Abstract: A spark plug assembly has a ceramic insulator with a metal outer shell surrounding at least a portion of the insulator. A ground electrode is operatively attached to the outer shell and a center electrode having an elongate body extends through the insulator. The center electrode and the ground electrode provide a spark gap. A force sensor is received about the insulator. An annular inner shell is received between the outer shell and the insulator, wherein the inner shell has a surface configured to confront the insulator along an axial direction.

Abstract translation: 电晕点火器包括具有沿着中心轴延伸的中心延伸构件的电极和从中心延伸构件径向向外延伸的表冠。 中心延伸部件具有延长的长度，并且冠部具有冠部长度。 延伸长度大于冠部长度，使得延伸部件接近比冠部更接近的活塞。 此外，冠部的点火尖部呈现小于中心延伸部件的第二球形半径的第一球形半径。 因此，如果发生电弧，则它从中心延伸部件而不是从表冠形成。 因此，冠的烧制尖端经受较少的磨损并保持锋利。 此外，由于球形半径的尺寸，从烧制尖端更可能形成电晕放电，而不是从中心延伸部件形成。
