摘要： A passive prechamber spark plug for use in a combustion chamber of a vehicle engine includes an upper prechamber having an upper opening where the upper prechamber is connectable to the combustion chamber via the upper opening. An air ignition spark is formable via an upper air spark gap. A central electrode is disposed in an upper region of the upper prechamber where a base of the upper prechamber opposite the upper region is an insulator. An electrically conductive element or a slot is guided by the insulator continuously from the upper prechamber into a lower region under the base and the lower region is either a lower prechamber or is arrangeable directly in the combustion chamber. An earth electrode is disposed in the lower region such that a lower air-surface gap spark gap is formed between the earth electrode and the electrically conductive element or the slot.

An ignition system is configured so that: to an auxiliary electrode is applied a voltage that is not more than a voltage applied between a center electrode and a ground electrode and that generates no spark discharge; the auxiliary electrode is positioned so that an electric field Ef2 between the auxiliary electrode and the ground electrode or an electric field Ef3 between the auxiliary electrode and the center electrode, which is generated by the applied voltage, is spread over the gap. A time for applying the voltage to the auxiliary electrode is controlled to include a time for applying the voltage between the center electrode and the ground electrode.
