    Abstract: A system including a controller. The controller is configured to obtain a signal from a knock sensor coupled to a reciprocating device. The controller 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. The controller is further configured to generate a first audio file of a 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.

    Abstract: A control system includes a first and second sensor configured to monitor a first type of operating condition of a first and second cylinder of an engine, respectively, a feedback component configured to monitor a second type of operating condition of the engine, and a controller communicatively coupled with the first and second sensors and feedback component. The controller is configured to receive a first measurement of the first type of operating condition from the first sensor, a second measurement of the first type of operating condition from the second sensor, and a third measurement of the second type of operating condition from the feedback component, to analyze the first and second measurements to detect a change in operating peak firing pressure in the first cylinder and/or in the second cylinder, and to analyze the third measurement to diagnose a cause of the change.
