Abstract: A high voltage ignition wire (10) has a ferrite core, a coiled wire (14) surrounding the core, and an insulating sheath surrounding the coiled wire. The coiled wire (14) is made from theoretically pure copper having a strand diameter of 0.081-0.099 inches. The coiled wire (14) is wound around the core between 140 and 160 turns per inch. The specific construction of this high voltage ignition wire (10) achieves an advantageous resistance of 13.5-16.5 ohms/ft.

Abstract: An ignition wire having low resistance and high inductance includes a ferrite core, a coiled wire surrounding the core, and an insulating sheath, where the high voltage ignition wire exhibits a resistance of 130-210 Ohms/ft and an inductance of 44-104 ?H. The coiled wire may have a diameter of 0.07-0.11 mm, 110-180 turns/in. and comprises a CuNi-based alloy. The coiled wire is preferably made of a CuNi-based alloy having, by weight, 80-95% Cu and 5-20% Ni. The ferrite core may include a core stranding which includes a ferrite core coating. The ferrite core coating may include, by weight, about 5.0-8.4% carbon, 31.7-37.8 oxygen, 1.5-1.7% copper, 0.6-0.8% aluminum, 0.1-0.2% sulfer, 7.0-11.6% zinc, 2.4-3.3 nickel and the balance iron and minor amounts of impurities.
