  • Spark plug
    Patent number: 10707653
    Abstract: A spark plug, including a metallic shell, an insulator, a center electrode, and a ground electrode. The insulator includes a first outer surface at least partly along an exposed portion and a second outer surface at least partly along an unexposed portion. The first outer surface extends between the exposed-unexposed interface to a tip merge portion adjacent a distal end of the insulator. The first outer surface and the second outer surface meet at a nose surface transition. At the nose surface transition, the first outer surface is disposed at a first angle with respect to a central axis of the spark plug, and the second outer surface is disposed at a second angle with respect to the central axis of the spark plug. The first angle is larger than the second angle, and the nose surface transition is located within the unexposed portion or at the exposed-unexposed interface.
