System and method for locating engine noise

A method of locating a coincident noise within a reciprocating device, comprising:

• utilizing a reciprocating device controller for:
• receiving noise signals from a plurality of knock sensors coupled to the reciprocating device at different locations associated with different cylinders of the reciprocating device, wherein each noise signal represents a noise signature of the reciprocating device detected at a respective knock sensor;
• analyzing the noise signals to detect a presence of the coincident noise within the reciprocating device;
• and
• determining, when the coincident noise is present, a location of the coincident noise within the reciprocating device based at least on the received noise signals from at least two knock sensors of the plurality of knock sensors.

A method of detecting a coincident noise within a combustion engine, comprising:

• utilizing an engine controller for:
• receiving noise signals from a plurality of knock sensors coupled to the combustion engine at different locations associated with different cylinders of the combustion engine, wherein each noise signal represents a noise signature of the combustion engine detected at a respective knock sensor;
• and
• comparing the received noise signals from different knock sensors of the plurality of knock sensors for matching noise signatures to detect a presence of the coincident noise and to identify which knock sensors of the plurality of knock sensors detected the coincident noise.
