OPTO-ELECTRONIC IGNITION

Since the autumn of 1967, SAE has been developing ignition systems using opto-electronic bistable triggers which accurately sense engine position at any speed and produce a constant crank angle dwell function in the same way as would a perfect set of cam-operated contacts. To date, over 10,000 of these systems are in use, and many have exceeded 150,000 miles of operation with only spark plug maintenance. This paper explains the preference for the bistable opto-electronic trigger and the reasons for choosing the engineering paths that have taken.
