Abstract
A glow plug has a heating element and a ceramic silicon nitride tip which has an outer surface. A low porosity refractory metal oxide coating covers at least a portion of the tip outer surface. A catalyst wire, with a diameter of 0.008 inches, is wrapped about and connected to the coated glow plug tip. The wire is formed of one of the platinum group metals and the wire is free of charge carrying connection to a power source.
