Spark plug design with specific electrode configurations
The patent US12027827B2 describes a novel spark plug design that features a center electrode, a tubular metallic shell, and a ground electrode. The center electrode is aligned along an axial line, while the ground electrode intersects this line. The ground electrode is secured within a penetration hole in the metallic shell, which includes a circular counterbore portion and a penetrating portion. This configuration allows for a spark gap between the forward end of the center electrode and the second end of the ground electrode. The design also incorporates a circular plate-shaped fixing portion on the ground electrode, which is affixed to the counterbore, and an extension portion that faces the center electrode, ensuring a specific orientation of the flat surface on the extension.
Further claims detail the orientation restrictions imposed by the penetrating portion on the extension of the ground electrode. These claims specify that the angle between the axial line and a plane perpendicular to the flat surface can be less than 90 degrees, with additional claims narrowing this angle to 45 degrees or even 5 degrees. The design also includes features such as a recess in the penetration hole that is larger than the counterbore and a closed-bottom tubular body with a separate jetting hole. This innovative spark plug design aims to enhance performance and efficiency in its application.
