ABSTRACT:
A method and system for determining optimum ignition times with regard to engine operation in which the engine is commanded, at regular, short-time intervals, to operate under conditions which cause knocking in order to be able to sense the knock limit. This is achieved, following the occurrence of a characteristic operating parameter in conjunction with a knock signal, at a frequency which is preferably significant, by storing an appropriately-corrected ignition-time value in a set of correction data, this ignition-time value lying somewhat beneath the knock limit. If the same characteristic operating parameter recurs, an optimum ignition time is accordingly indicated, which lies slightly beneath the knock limit. This procedure enables the engine to be operated under conditions which are optimum with regard to fuel consumption, without entering the knocking range with excessive frequency.
