Abstract (en)

[origin: DE19818214A1] The spark plug has a rod-shaped conductor arrangement consisting of a contact bolt, a current limiting resistor (13), a contact pin (15) and a middle electrode (16). The current limiting resistor consists of two regions of different cross-section. The cross-section in the region facing combustion is smaller than the cross-section in the region facing away from combustion. The region of the resistor facing away from combustion may lie outside the foot region of the spark plug.
