Abstract (en)

[origin: EP0713006A1] The spark plug includes the primary winding on a magnetic core (1) which is surrounded by a compartmented secondary former (3) and fed with DC via a connector (5). The two windings are enclosed in a casing (7) threaded (8) at the other end for insertion into the cylinder head. The high-voltage electrode (11) projects from the threaded end towards the tip of the earth electrode (9), and is energised from the secondary winding via a conductor (12) insulated from the ceramic base (13). The high-voltage assembly (11-13) is encased first, followed by the windings and an insulating resin which fills the casing.
