Abstract (en)
[origin: US2004079745A1] A pin heater (1) in a sheathed-element glow plug (5) and a sheathed-element glow plug (5) for internal combustion engines, which have improved electrical and mechanical properties, are described. The pin heater (1) has at least one essentially internal insulating layer (10) and one essentially external first conductive layer (15, 16), both layers (10; 15, 16) including ceramic composite structures. The pin heater (1) includes a second conductive layer (20), which also includes a ceramic composite structure. The second conductive layer (20) is bonded to the first conductive layer (15, 16) in the region of a combustion chamber side tip (40) of the pin heater (1). The second conductive layer (20) runs inside the insulating layer (10).
