Abstract
A real-time, dynamic method for creating a body of cycle-and-cylinder-specific noise-reduction baseline data useable in conjunction with analyzing the engine-knock behavior of a subject internal combustion engine involving operating the engine in an operating mode wherein engine knock may occur, and while doing so, and during each cycle of each cylinder, gathering cycle-and-cylinder-specific, knock-free, engine-operating, baseline noise data which is intended and dedicated for noise-reduction use solely with respect to analyzing any knock data found to exist in the same operating cycle.
