Abstract
A capacitor discharge ignition system is provided in a self-contained hermetically sealed housing having improved component packaging. The capacitor discharge ignition system includes an ignition coil and an auxiliary coil for charging a capacitor of the capacitor discharge ignition system in response to a rotating magnetic field. The auxiliary coil is fabricated with a coil shape factor having a greater height and lower mean turn diameter than conventional auxiliary coils. The lower mean turn diameter of the auxiliary coil provides space within the housing for circuit components of the capacitor discharge ignition system to be placed between the auxiliary coil and the inner wall of the housing. Thus, the circuit components are removed from the conventional location between the primary and secondary windings of the ignition coil. The removal of the circuit components from the ignition coil assembly provides an improved ignition coil with increased coupling to allow the ignition coil to be fabricated with less coil wire and a smaller volume than conventional coils. The improved ignition coil is thus fabricated with a narrower height factor. A capacitor discharge ignition system is a…
