ABSTRACT:
The values of dwell and ignition timing signals from which ignition dwell and spark timing are provided are controlled to minimize power dissipation in an electronic ignition system and to ensure that adequate dwell times are provided during engine acceleration conditions and large advance angle increases. The dwell signal is increased from a static dwell value during steady state engine operation to a higher value in response to sensed engine accelerating conditions and the change in the spark advance between ignition events is limited to ensure that an adequate dwell period is provided.
