Abstract
An ion sensor glow plug assembly includes a shell for attachment to a cylinder head of a compression ignition engine and having a passageway extending axially therethrough. The ion sensor glow plug assembly also includes a center terminal disposed at least partially in the passageway of the shell and connected to a source of power to create a heating circuit. The ion sensor glow plug assembly includes a glow sheath disposed at least partially in the passageway of the shell and about the center wire to create an ion sensing circuit. The ion sensor glow plug assembly further includes a coating disposed about a portion of the glow sheath between the glow sheath and the shell to isolate the shell from the glow sheath.
