Spark plug design with specific electrode dimensions and insulator structure
A recently granted patent (Publication Number: US11862943B2) discloses a unique spark plug design comprising a center electrode with specific structural features. The spark plug includes a center electrode with a leg portion, a brim portion protruding radially, and a connecting portion. An insulator supports the center electrode with a penetration hole filled with a seal member to fix the brim portion and the insulator. The insulator has a large diameter portion at the rear end, a small diameter portion at the top end, and a step portion supporting the connecting portion. The center electrode must meet specific dimensional criteria, including a maximum radius of the brim portion and a size ratio along the axis direction.
Furthermore, the patent claim specifies that the sizes of the center electrode, denoted as L1 and L2, must satisfy a specific ratio to ensure optimal performance. Specifically, the ratio L2/L1 must be less than or equal to 0.25. These structural features and dimensional requirements aim to enhance the efficiency and effectiveness of the spark plug in igniting fuel in internal combustion engines. The patented design represents a novel approach to spark plug construction, potentially offering improved performance and reliability in various engine applications.
