Abstract:
A spark ignition system for generating an ignition event in an internal combustion engine having at least one combustion chamber, comprising:a. a capacitive discharge system for repeatedly generating a predetermined voltage at a predetermined frequency;b. a core-coil assembly connected to said capacitive discharge system for receiving said predetermined voltage, said core-coil assembly having a magnetic core composed of a ferromagnetic amorphous metal alloy, said core-coil assembly further comprising:(i) a primary coil wound about said magnetic core and being connected to said capacitive discharge system for voltage excitation thereby; and(ii) a secondary coil wound about said magnetic core and adapted for excitation by said primary coil and for generating a high voltage output from said core-coil assembly;c. said secondary coil comprising a plurality of stacked core-coil sub-assemblies connected in series with each other that are simultaneously energized in response to the voltage excitation of said primary coil, each of said core-coil sub-assemblies comprising a toroidally wound section having a coil wound in a predetermined direction;d. said core-coil sub-assemblies, when simultaneously energized by said primary coil, producing secondary voltages that are additive and which are collectively fed to a spark plug to generate the ignition event in the internal combustion engine.
