Abstract

See full text

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.
