PROBLEM TO BE SOLVED: To provide a method for operators to confirm an occurrence of knocking of an internal combustion engine.SOLUTION: A controller obtains a signal from a knock sensor coupled to a reciprocating device. The controller analyzes the signal to determine a trigger event occurrence on the basis of the signal having an abnormal signature. The abnormal signature is associated with knocking of the reciprocating device. The controller generates a first audio file of first audio recording to store in a memory of the controller. The first audio recording provides an indication of the knocking of the reciprocating device.SELECTED DRAWING: Figure 1 |
