Abstract
Applicant has disclosed an improved dual cycle ignition system for automobiles. In the preferred embodiment, the improved ignition system comprises at least two secondary ignition coils wired in a high voltage 'OR' configuration using a single high voltage circuit through a distributor, or alternatively a single plug operated directly from diodes connected respectively to associated secondary coils. The ignition coils are set up to alternate sparks, so that even at 8000 engine RPM, each coil is firing as if operating at 4000 RPM, a speed where conventional highly optimized and inexpensive coils are very effective and can reach their full output.
