Abstract: An ignition coil assembly for an internal combustion engine including an ignition coil housing having integrally molded mounting members arranged on the outer perimeter of the housing in non-interfering relationship with the internal coil/core assembly components. C-Shaped laminated cores are encased entirely within the ignition assembly housing material or encased in an elastomer such as a rubber modified polypropylene and inserted into the housing assembly. The ignition coil assembly provides for use either in a internal combustion engine with a distributor-based or distributor-less ignition system.

Abstract: A method of making a unitary spark distribution cassette involves molding a cassette and placing electrically conductive lead frames within the cassette during molding. Electrically conductive sleeves for fitting over spark plugs are also provided on the cassette. An ignition system circuit using high voltage diodes in conjunction with an alternating flux ignition coil is placed in the cassette and connected to the lead frames and the sleeves to create a complete electrical circuit. The cassette is then filled with epoxy resin to encase the electrical components to form a unitary package.
