Abstract: An extruded insulator for a spark plug that is made in a manner that minimizes pores, relics and/or other defects in the insulator microstructure so that the overall dielectric strength or performance of the insulator is improved. The extruded insulator avoids many of the drawbacks associated with such defects, but also has a stepped internal bore for receiving a center electrode. In one embodiment, the extruded insulator is made with a method that uses a multi-phase extrusion process to extrude a ceramic paste around an elongated arbor and form an extruded section, and then removes the arbor from the extruded section to reveal a stepped internal bore.

Abstract: A manufacturing method, firing tray, and microwave kiln for spark plug insulators. Using microwave energy and particularly structured time-temperature profiles may allow for efficient sintering of the spark plug insulator ceramic material. The method may use a combination of radiant heat energy heating and microwave energy heating to facilitate the sintering process.

Abstract: 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.

Abstract: Methods of making an insulator for a condition sensing spark plug and tooling that can be used to perform the various methods, the tooling and methods involving machining one or more channels in the insulator body. The machined channels can be used to accommodate one or more wires from a sensing, display, or processing device. In one particular example, the wires are thermocouple wires used to sense temperature in an internal combustion engine while the spark plug is in use. The methods and tooling may result in channels that are formed more precisely, economically, and efficiently.

Abstract: A spark plug suppressor and a method of producing a spark plug suppressor from a suppressor precursor liquid that may be cured at a temperature below 300° C. The spark plug suppressor may include particles or grains dispersed in a matrix of electrically conducting material, electrically semiconducting material, or electrically non-conducting material. The suppressor may include a conductive glass seal component and a resistive suppressor component. The resistive suppressor component may be at least partially embedded in the glass seal component, and the glass seal component may seal a center electrode of the spark plug, a terminal of the spark plug, or both the center electrode and the terminal.
