A method for identifying a cause of a machine operating anomaly including creating a reduced order model (ROMs) for a digital twin model of a selected machine type and feeding current data from a deployed machine into the ROM. The method can include comparing a current output from the selected ROM with a measured output from the current data and determining that an operating anomaly exists when the difference between the current output and the measured output exceeds a selected anomaly threshold. The cause of the operating anomaly can be identified by feeding the current data into a plurality of fault models, wherein each fault model includes a particular component failure, comparing a fault model output from each of the plurality of fault models with the measured output from the current data, selecting the fault model with the fault model output most closely matching the measured output, and displaying the identified component failure associated with the selected fault model as the cause of the operating anomaly.

Systems and methods for lubricant dilution detection are disclosed. A method for detecting lubricant dilution for a lubrication system includes detecting a low idle condition. The method includes receiving sensed values indicative of lubricant pressure and lubricant temperature during the low idle condition. The method also includes determining a lubricant pressure threshold based on the sensed value indicative of lubricant temperature. The method further includes determining lubricant dilution based on the sensed value indicative of lubricant pressure and the determined lubricant pressure threshold during the low idle condition. In accordance with a determination that there is lubricant dilution, the method includes outputting an indication of the lubricant dilution.

The present disclosure is directed to systems and methods for virtualizing communications within a plurality of telematics channels operatively connected to a target machine. The method includes (i) generating a virtualized channel in addition to the plurality of telematics channels operatively connected to the target machine; (ii) predicting one or more values for the virtualized channel based on a mathematical function derived from a first set of telematics channels of a source machine; (iii) receiving measurements from the plurality of telematics channels from the target machine; and (iv) applying the mathematical function to the target machine based upon the one or more predicted values of the virtualized channel and the received measurements from the plurality of telematics channels from the target machine.
