Abstract
La candela (1) presenta uno strato (13) di polimero fluorocarbonico sulle superfici (11) dell'elemento isolante (3) esposte direttamente all'atmosfera in prossimità dell'elettrodo centrale (4) e/o affacciate al corpo metallico tubolare esterno (2) in modo da evitare l'imbrattamento dell'elemento isolante 3 da parte di residui carboniosi.(Figura unica).The spark plug (1) has a layer (13) of fluorocarbon polymer on the surfaces (11) of the insulating element (3) exposed directly to the atmosphere near the central electrode (4) and / or facing the external tubular metal body ( 2) so as to avoid the soiling of the insulating element 3 by carbon residues (single figure).
