ABSTRACT:
An ignition timing control system for an internal combustion controls the ignition timing in dependence upon an indicative pressure signal representing changes of the inner pressure within the combustion chamber of the engine. The ignition timing control system ceases the feed-back control based on the indicative pressure signal but performs an open loop control under predetermined engine operational conditions.
