Patent ID: 7614376

Claim:
An engine combustion chamber plug, comprising: a casing member having an externally threaded emitter portion adapted for threading into an engine combustion chamber, the emitter having a cavity disposed along an axial center of the casing member, the cavity having sidewalls forming a charge plate, the casing member having an electrode connecting portion; external threads disposed on the electrode connecting portion of the case member, the external threads being adapted for connecting a positive electrode thereto for energizing the charge plate; a passageway extending lengthwise from the cavity of the emitter portion of the casing into the electrode connecting portion of the casing; an electrically conductive tip disposed on the electrode connecting portion and extending upward from the passageway, the electrically conductive tip being adapted for electrical connection of a negative electrode thereto; a hollow insulation member disposed in the passageway, the insulation member being fabricated from a material having high temperature insulation characteristics; and a filament coil disposed in the cavity, the filament coil emitting photons when heated to high temperatures, the coil having one end routed through the hollow insulation member and electrically connected to the tip, and an opposite end electrically connected to the external threads on the electrode connecting portion of the casing; wherein when an electrical current is applied to the electrode connections of the plug while it is operationally attached to the combustion chamber, the filament glows white hot, emitting photons to improve combustion in the chamber.
