ABSTRACT:
An improved capacitive discharge ignition apparatus provides spark advance with engine speed. The ignition apparatus includes at least one trigger circuit including a trigger coil preferably contained in a common housing with other circuit elements. In this case, an auxiliary coil may be provided to cancel certain pulses in the trigger coil output that could otherwise interfere with desired operation. In some embodiments, a second trigger circuit is provided to derive a triggering signal from the primary coil of the ignition's step-up transformer. A triggering signal of appropriate magnitude received from either trigger circuit will cause discharge of an energy storage element through the primary coil.
