Abstract: An engine diagnostic system includes a control system having a controller operatively connected to an engine. A monitoring system has a sensor operatively connected to the engine. A diagnostic system is operatively connected to the engine. The diagnostic system is configured to implement a sensor diagnostic procedure that includes a sensor health test. The sensor health test includes comparing a measured value of a sensor to an expected value and determining the health of the sensor based on the difference between the measured value and the expected value. The sensor diagnostic procedure can also include telematics data analysis.

Abstract: A turbocharged device including a turbocharger, a first sensor in operable communication with the turbocharger and configured to output a first signal representative of a first attribute of the turbocharger, and a controller in operable communication with the first sensor. Where the controller is configured to calculate a first preliminary surge score based at least in part on the first signal, and calculate a first weighted surge score based at least in part on the first preliminary surge score and a first weighting factor configured to express the relative significance of the first preliminary surge score.

Abstract: Systems and methods are provided for a diagnostic system for a machine with a combustion engine and a variable geometry turbocharger that includes a vane position sensor. The diagnostic system includes a controller configured to calculate a learned span value of the turbocharger based on the output of the vane position sensor during a diagnostic procedure and a reference vane position sensor value. A plurality of learned span values are calculated each during a different one of a plurality of diagnostic procedures performed over a period of time and a first regression analysis to predict an expected learned span value at a defined future time using the calculated learned span value and the plurality of stored learned span values. An alert message is generated when the expected learned span value is indicative of a potential future fault of the turbocharger.

Abstract: A service diagnostic trouble code sequencer and method is disclosed that includes receiving multiple diagnostic trouble codes (DTCs), determining which DTCs to diagnose first, and recommending which DTC(s) to diagnose first. The sequencer can recommend a category of DTCs to diagnose first, where the category of DTCs includes one or more DTCs. The sequencer can prioritize the DTCs in the category of DTCs. The sequencer can separate the DTCs into multiple categories of DTCs, and prioritize the multiple categories of DTCs. The sequencer can prioritize the DTCs in an ordered category of the multiple categories of DTCs. The sequencer can receive the plurality of DTCs locally or remotely over a network. The sequencer can output the one or more DTCs to diagnose first locally or remotely over a network. The sequencer can be resident on the machine generating the DTCs.

Abstract: A method of collecting a strand using an air stream dissipater comprises texturizing the strand with an air stream on a first side of the air stream dissipater, directing the texturized strand through the air stream dissipater and collecting the texturized strand in a container on the second side of the air stream dissipater. A system for texturizing a strand comprises a texturizer for texturizing the strand with an air stream, a container to collect and hold the texturized strand and an air stream dissipater provided between the texturizer and the container to dissipate excess air from the air stream and prevent the excess air from entering the container.
