Ground electrode free ignition device for internal combustion engine of motor vehicle, has Tesla coil formed by radially expanding windings having non-circular cross-section, arranged so that broad sides of windings face one another

摘要

The device (3) has housing (13) with ignition electrode (4) and Tesla coil (10) that is electrically connected with the ignition electrode. The Tesla coil is formed by radially expanding windings having non-circular cross-section. The broad sides of winding portions of the radially extending windings are arranged to face one another. The windings are comprised of insulating film and electrical conductive foil. The width of insulating film is larger than the width of electrical conductive foil.
