ABSTRACT:
An electronic, solid-state ignition system for an internal combustion engine is disclosed which is responsive to alternating timing signals produced in timed relationship with the engine cycling. The electronic system comprises a plurality of integrator circuits, a transistorized output stage and a feedback loop for linearly regulating the current limit duty cycle to be a fixed percent of the firing cycle time period independent of current ramp time through the coil. As a result, sufficient spark potential is developed and predetermined spark timing is produced thereby preventing mis-spark even though the engine may be accelerating at a maximum specified rate or decelerating.
