整片外壳的高螺纹火花塞
摘要：
披露了一种用于引燃内燃机内气体的火花塞。该火花塞具有中央电极，绝缘体，整片的外壳，以及接线端。该中央电极与能量源相连接。该绝缘体围绕该中央电极。该整片外壳围绕并接触该绝缘体，用于在外壳内固定该绝缘体，其中该外壳在第一末端附近具有多个螺纹，并且接地电极连接到该外壳并在第二末端与该中央电极的端头对准，以限定火花间隙。另外，在外壳内于多个螺纹和接地电极之间形成一个座，用于相对于该发动机密封外壳。该接线端具有与中央电极相连接的第一末端以及具有连接部的第二末端，该连接部用于连接到该能量源。
摘要（英）：

A spark plug for igniting gases in an internal combustion engine is disclosed. The spark plug has a center electrode, an insulator, a one-piece shell, and a terminal. The center electrode is in communication with an energy source. The insulator surrounds the center electrode. The one-piece shell surrounds and contacts the insulator for securing the insulator within the shell, wherein the shell has a plurality of threads near a first end and a ground electrode attached to the shell and aligned with a tip of the center electrode at a second end to define a spark gap. Further, a seat is formed in the shell between the plurality of threads and the ground electrode for sealing the shell against the engine. The terminal has a first end in communication with the center electrode and a second endwhich has a connector portion for connecting to the energy source.
