SYSTEM AND METHOD FOR LOCATING ENGINE NOISE

A system 10 includes a controller 25 configured to receive noise signals acquired by at least two knock sensors 23 of a plurality of knock sensors coupled to a reciprocating device 54. Each noise signal represents a noise signature of the reciprocating device detected at a respective knock sensor 23. The controller 25 is also configured to determine a location of a coincident noise within the reciprocating device 54 based at least on the received noise signals.
