ABSTRACT:
A spark timing control system for an internal combustion engine is responsive to a changing engine operating parameter signalling an engine tip-in event to retard spark timing by an amount sufficient to eliminate tip-in knock and for a predetermined time period ending 175-300 milliseconds after initiation of the tip-in event, so that no perceptible engine performance loss results.
