A rod-shaped inner conductor structure fits in the insulator and has a terminal stud (11), a current-limiting resistor (12), a coated contact pin (13) and a central electrode (5). An earth electrode fits on the casing. The central electrode and/or the earth electrode have a feeder area (8) for feeding a combustible mixture to a preset spark gap. An Independent claim is also included for a combustion chamber structure with a spark plug and an injection valve that has two injection holes, whose mixture jets flank the spark plug.",
