摘要: A sheathed-element glow plug to be mounted in a combustion chamber is proposed, a rod-shaped heating element being situated in a concentric bore hole of the housing. The heating element has a first current-carrying layer, a second current-carrying layer, and an insulating layer, the insulating layer separating the first current-carrying layer and the second current-carrying layer. The first current-carrying layer and the second current-carrying layer being connected at the end of the heating element on the combustion chamber side by a conducting-layer crosspiece. The first current-carrying layer and the second current-carrying layer are different lengths, the cross section of the first current-carrying layer in a first section at the end of the heating element away from the combustion chamber being greater than the cross section of its remaining length, and the second current-carrying layer not extending into the first section.

摘要: A pin heater in a sheathed-element glow plug and a sheathed-element glow plug for internal combustion engines, which have improved electrical and mechanical properties, are described. The pin heater has at least one essentially internal insulating layer and one essentially external first conductive layer, both layers including ceramic composite structures. The pin heater includes a second conductive layer, which also includes a ceramic composite structure. The second conductive layer is bonded to the first conductive layer in the region of a combustion chamber side tip of the pin heater. The second conductive layer runs inside the insulating layer.
