spark coil

• Type de bobine d'induction électrique utilisée dans les systèmes d'allumage, en particulier dans les anciens moteurs à combustion interne, pour générer des étincelles à haute tension destinées aux bougies d'allumage.

A type of electrical induction coil used in ignition systems, particularly in older internal combustion engines, to generate high-voltage sparks for spark plugs.
