Abstract: A spark plug having a resistor containing SiO2 and B2O3. The glass is a phase-separated glass having aggregate phase and an intervening phase. In a cross section of the resistor, when a plurality of imaginary lines perpendicular to an axial line CL1 are drawn at intervals of 0.1 mm in the direction of the axial line CL1, the number of aggregate phase located on each of the imaginary lines is determined, and the average number of aggregate phase per imaginary line is determined for each of a plurality of line groups each comprised of five consecutive imaginary lines, there are three or more consecutive line groups which satisfy the condition that the average number of aggregate phase per imaginary line is larger, by 5 or more, than the minimum average number of aggregate phase per imaginary line among the plurality of line groups.

Abstract: The plug comprises a nut, a coupling extending from the nut and adapted to receive an ignition wire and an insulator extending from the nut and away from the coupling. A positive electrode extends through the insulator. An externally-threaded tubular portion extends from the nut in surrounding relation to the insulator and terminating, short of the insulator end, in a cap that is disposed in spaced relation to the insulator. The cap defines a void having: a central portion into which the positive electrode extends; an annular channel surrounding the central portion; and a plurality of lobes, each positioned with respect to the central portion as the planet gears are positioned with respect to the sun gear in a planetary gear. The cap has a central surface that is axially spaced from the insulator and a convex surface that surrounds and extends to the central surface.

Abstract: A spark plug is disclosed and comprises: a metal tube which interiorly defines an axis and is externally-threaded for engine block engagement; an insulator having a portion which is disposed inside the tube and extends therebeyond; a positive electrode extending through the insulator and projecting beyond the extending portion of the insulator; and an annular ground electrode coupled to the tube. The electrodes are configured such that a spark gap defined therebetween comprises an elongate channel which opens axially and away from said insulator and is substantially unobstructed in the axial direction. The ground defines a void having: a central portion occupied by the positive electrode in use; an annular channel surrounding the central portion; and a plurality of lobes, each being positioned with respect to the central portion in a manner analogous to the placement of the planet gears with respect to the sun gear in a planetary gear

Abstract: A direct spark igniter for a fuel-fired heating appliance is provided with enhanced ignition performance in environments having substantial levels of both moisture and pollution. Such enhanced ignition performance is representatively achieved by the combination of (1) forming external annular ribs on the ceramic body portion of the igniter; (2) extending a top end of the igniter electrode rod into the body portion; (3) bending the igniter electrode and ground rods and angling them toward one another; and (4) knurling external side surfaces on lower end portions of the igniter electrode and ground rods.
