Abstract
A method is provided for controlling knock in an internal combustion engine. The method utilizes an adaptive control scheme to tailor knock thresholds to the current engine operating conditions, as well as to identify the cylinder in which the knocking condition occurred. The method utilizes a modified spark advance to alter the spark timing for the engine cylinders if a knocking condition is detected and a predetermined set of conditions has been met.
