IC engine ignition timing control - uses rotation sensor to detect actual ignition timing compared with calculated ignition timing

摘要

The ignition timing control uses the monitored engine operating parameters to calculate the required ignition timing point. The actual ignition timing point is detected, together with the period between 2 successive ignition timing points. The calculated ignition timing and the actual ignition timing are compared t up date the ignition timing control signal. - Pref. the actual ignition timing is detected using a rotation sensor for detecting a reference angle of the crankshaft.
