Latest Patents

Sasaki's latest patents include an insulator on a spark plug electrode coated with zirconium and vanadium. This invention features a spark plug that comprises an insulator surrounding a central electrode and a housing with a grounded electrode. The taper-nose portion of the insulator is designed to be exposed to unburnt carbon in combustion gases. The modification involves a coating of a mixture of vanadium oxide and zirconium oxide, which enhances the self-cleaning ability of the spark plug while maintaining excellent electrical insulation. The coating is formed by applying a suspension of the mixture to the taper-nose portion and drying it in situ, followed by further heating for increased durability.

Another patent by Sasaki involves a spark plug with vanadium oxide islands on the central insulator. This design ensures that the central electrode is electrically insulated from an outer electrically-conductive casing. The taper-nose portion is modified to facilitate carbon removal, with discrete particles of vanadium oxide adhered to the exposed surface. This innovation also improves the self-cleaning ability of the spark plug without compromising electrical insulation.
