Beschreibung
Zusammenfassung:	A spark plug (12) having an insulating body (50) defining a longitudinal axis A1 and including a base portion (60) and an obstruction portion (62), a first electrode (52) including a proximal portion (70), a sheathed portion (72) and a distal portion (75), the sheathed portion of the first electrode extending through the base portion of the insulating body, and a second electrode (54) including a proximal portion (80), a sheathed portion (82) and a distal portion (84), the sheathed portion of the second electrode extending through the base portion and the obstruction portion of the insulating body, wherein the obstruction portion axially extends beyond the distal portion of the first electrode. 火花塞12具有绝缘主体50、第电极52和第二电极54，该绝缘主体50限定纵向轴线A并且包括基座部分60和阻塞部分62，该第电极52包括近端部分70、护套部分72和远端部分75，第电极的护套部分延伸穿过绝缘主体的基座部分，该第二电极54包括近端部分80、护套部分82和远端部分84，第二电极的护套部分延伸穿过绝缘主体的基座部分和阻塞部分，其中阻塞部分轴向地延伸超过第电极的远端部分。
