Latest Patents

Luckman's latest patents include a Spark Timing Control System and an Electronic Ignition System. The Spark Timing Control System is designed for uneven firing engines and utilizes a microprogrammed engine controller. This system produces spark timing based on internal calculations using spark advance and dwell variables supplied by a microcomputer. A crankshaft position transducer generates a reference signal with alternating long and short pulses, allowing the determination of the firing cycle. The microcomputer is interrupted at each falling edge of the reference signal, calculating and supplying appropriate spark advance and dwell numbers to the controller based on the existing firing cycle.

The Electronic Ignition System patent focuses on minimizing power dissipation while ensuring adequate dwell times during engine acceleration. The system controls the values of dwell and ignition timing signals, increasing the dwell signal from a static value during steady-state engine operation to a higher value in response to sensed engine acceleration. This approach limits the change in spark advance between ignition events, ensuring an adequate dwell period is maintained.
