Abstract (en)
[origin: WO2017186239A1] A spark plug, in particular a prechamber spark plug, comprises a housing (5), an ignition electrode (4) and a ground electrode (1), a supply line (9) being provided for applying a voltage to the ignition electrode (4), said supply line (9) having a front portion (10) facing the ignition electrode (4) and a rear portion (11) facing an ignition coil; the disclosed spark plug is characterized in that exclusively the rear portion (11) of the supply line (9) has a sufficiently high electric resistance to act as an interference suppression resistor.
