SIGNAL RECORDING OF KNOCKING CONDITIONS USING A KNOCK SENSOR

A system including a controller (25). The controller (25) is configured to obtain a signal from a knock sensor (25) coupled to a reciprocating device (10). The controller (25) is configured to analyze the signal to determine a trigger event occurrence based on the signal having an abnormal signature. The abnormal signature is associated with a knocking of the reciprocating device (10). The controller (25) is further configured to generate a first audio file of a first audio recording to store in a memory of the controller (25). The first audio recording provides an indication of the knocking of the reciprocating device (10).
