Abstract: A spark plug has a shell, an insulator, a center electrode, a ground electrode, and a firing pad. The firing pad is made of a precious metal material and is attached to the ground electrode. The firing pad has a side surface at a peripheral edge that can be flush or nearly flush with a free end surface of the ground electrode. This construction can help improve ignitability and flame kernel growth of the spark plug during a sparking event, and can provide better thermal management at the attached ground electrode and firing pad.
Abstract translation: 火花塞具有外壳，绝缘体，中心电极，接地电极和击发垫。 击发垫由贵金属材料制成，并附着在接地电极上。 触发垫具有在外围边缘处的侧表面，其可以与接地电极的自由端表面齐平或几乎齐平。 这种结构有助于在火花事件期间提高火花塞的可燃性和火焰核生长，并且可以在附着的接地电极和击发垫处提供更好的热管理。

Abstract: A spark plug has a firing pad attached to a center electrode or a ground electrode by way of a fused portion. In one or more embodiments, the firing pad is composed of a precious metal material. The fused portion can be formed in such a way that a material composition thereof at a sparking surface of the firing pad has a greater percentage of the precious metal material than a material of the underlying electrode to which the firing pad is attached.
Abstract translation: 火花塞具有通过熔融部分附接到中心电极或接地电极的发射焊盘。 在一个或多个实施例中，击发垫由贵金属材料构成。 熔融部分可以以这样的方式形成，使得其在焙烧垫的火花表面处的材料组成比具有烧结垫的底部电极的材料具有更大百分比的贵金属材料。

Abstract: A spark plug having a metal shell, an insulator, a center electrode, a ground electrode, and a multi-layer sparking component. The multi-layer sparking component is attached at a firing end of the ground electrode and includes a thin precious metal layer formed overtop a base metal layer and, according to some embodiments, overhangs the end of the ground electrode. The precious metal and base metal layers may be pre-manufactured together as a bi-metal ribbon, sheet or laminate before the multi-layer sparking component is attached to the ground electrode.
