Latest Patents

Enomoto’s patent, “Spark Plug for Use in Internal Combustion Engine,” describes a spark plug with a metallic shell, a tubular insulator, a center electrode, and an outer electrode that form a spark gap. Two stepped portions near the front of the center electrode create clearance between the electrode and the insulator, with their diameters decreasing toward the electrode’s front end. A beveled, tapered portion at the insulator’s front opening works with this arrangement to help maintain insulation and reduce carbon deposits, thereby lowering the risk of ignition failure.

Career Highlights

The patent reflects Enomoto’s work on spark plug design and the practical challenges of reliable ignition in internal combustion engines. His listed company affiliation is NGK Spark Plug Company, Limited.
