ABSTRACT:
In a feed-back engine control system in response to an indicative pressure signal representing the inner pressure of the combustion chamber of an internal combustion engine, uncertain states are detected by comparing peak positions appearing in the respective ones of the indicative pressure signal and the filtered indicative pressure signal, thereby to avoid unfavorable operation of the system.
