Abstract
A capacitive discharge ignition (CDI) system for generating ignition sparks in an internal combustion engine comprises a single CDI module including a plurality of charge storage capacitor devices, a corresponding plurality of sets of ignition outputs, at least one charging circuit for charging at least one of the plurality of charge storage capacitor devices, and an ignition controller for selectively and individually controlling each of the plurality of charge storage capacitor devices and the at least one power supply circuit. Each of the plurality of charge storage capacitor devices is operatively coupled to the ignition outputs of one of the plurality of sets of ignition outputs. This allows for the single CDI module to power multiple, independent spark plugs either simultaneous of, immediately prior to or after each other while still delivering full energy to each ignition device.
