An algorithm to detect knock location was developed, utilizing differences in the arrival time of the presure wave by knocking between 5 pressure sensors in the combustion chamber of a gasoline engine. In this algorithm, the time differences were derived from time-frequency analysis of the Fourier spectrum with an accuracy of several microseconds. Furthermore, calculation of knock location by the least square method correlated with the results of the experiment with minimum error. It was applied under certain conditions in a single cylinder engine, and knock locations were determined for both homogenous and stratified combustion.
