摘要： The invention relates to an essentially-elongated spark plug (1) for the internal combustion engine of a motor vehicle, consisting of: an essentially-capacitive (C) lower part comprising two coaxial electrodes (2, 3); an essentially-inductive (I) upper part comprising a central mandrel (8), a coaxial winding (5) around the mandrel (8) and an external tubular casing (61) which serves as electromagnetic armour; and an insulant (7) which is disposed radially between the casing (61) and the winding (5). The invention is characterised in that the essentially-inductive upper part (I) comprises a second internal casing (62) of electromagnetic armour, which is disposed radially between the insulant (7) and the external casing (61).

摘要： The invention concerns a spark plug (1) for a motor vehicle internal combustion engine, substantially elongated in shape, comprising: two coaxial electrodes: an inner electrode (D) called central electrode (3) and an outer electrode called base (2) enclosing the central electrode (3); an electrically insulating annular block, called insulation (4) interposed between the central electrode (3) and the base (2) having an annular shoulder (5). The invention is characterized in that the insulation (4) comprises an annular groove (8) located at the shoulder (5).
