Latest Patents
Kazumi Kawamura holds a patent for a spark plug attachment structure and the spark plug itself. This invention features a central electrode and an insulator that surrounds it, all contained within a metallic shell that lacks threading. The design allows the spark plug to be clearance fitted into a plug hole of a cylinder head without being screwed in. This method ensures that the front end portion of the metallic shell is properly accommodated within the plug hole, utilizing a sealant to facilitate heat transmission from the spark plug to the cylinder head. The clearance is defined by the expression: 0.005 ≤ D - d ≤ 0.05, where D represents the inner diameter of the front end section and d denotes the outer diameter of the front end portion. This innovative design simplifies the attachment process and improves heat resistance.
