    Abstract: 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.

    Abstract: A machine has a power source and a cooling system configured to circulate coolant between the power source and a heat exchanger. The cooling system has a first sensor configured to sense an ambient temperature and provide a first signal indicative of the ambient temperature and a second sensor configured to sense an actual temperature of the coolant and to provide a second signal indicative of the actual coolant temperature. The cooling system has a controller in communication with the first and second sensors to receive the first and second signals. The controller is configured to calculate, based on the ambient temperature and on a model for the heat exchanger, a predicted coolant temperature, and to compare the predicted coolant temperature to the actual coolant temperature. The controller is further configured to provide an alert based at least in part on the comparison.

    Abstract: A heat exchanger for an exhaust gas recirculation unit is provided. A tube core of the heat exchanger includes a plurality of coolant channels disposed between a plurality of exhaust gas tubes extending from an upstream face to a downstream face. A coolant inlet line and a first coolant outlet line is disposed in a first quarter section of the tube core defined between the upstream face and one fourth of a length of the tube core adjacent to the upstream face. The first coolant outlet line is configured to draw at least a portion of a coolant flow across the upstream face and into the first coolant outlet line. Further, a second coolant outlet line is provided and is configured to discharge a remaining portion of the coolant flow from the plurality of coolant channels that was not drawn out of the first coolant outlet line.
