Zusammenfassung:	A system for harmonizing knock in a plurality of cylinders included in an engine, the system comprises a plurality of knock sensors, and a controller coupled to each of the plurality of knock sensors. The controller is configured to receive a plurality of cylinder knock values corresponding to each of the plurality of knock sensors, and receive an average knock value. The controller determines a cylinder spark timing offset value for each cylinder in the plurality of cylinders from the average knock value and the cylinder knock values. The controller determines an average spark timing offset value. The controller also determines an adjusted spark timing value for each of the plurality of cylinders by subtracting the average spark timing offset value from a spark timing value of each of the plurality of cylinders.
