Abstract: Techniques for detecting failures associated with fuel distribution systems. The techniques may include receiving first oil pressure data associated with an engine of a machine and receiving second oil pressure data associated with a high-pressure pump supplying fuel to the engine. Based at least in part on the first oil pressure data and the second oil pressure data, an impending failure associated with the high-pressure pump may be determined. For instance, utilizing the first oil pressure data and the second oil pressure data, a difference between a first oil pressure value associated with the engine and a second oil pressure value associated with the high-pressure pump may be calculated. The difference in the oil pressure values and the second oil pressure value may be indicative of the impending failure. In some instances, an action may be performed based on detecting the impending failure.

Abstract: A hybrid propulsion system for a locomotive is disclosed. The hybrid propulsion system comprises: ground engaging elements associated with the locomotive; a prime mover for powering propulsion of the ground engaging elements; a traction motor associated with the ground engaging elements; a battery associated with the traction motor; and a controller. The controller includes a route dataset having a topography of a route of the locomotive. The controller is configured to: analyze the topography of the route and location of the locomotive; identify when the locomotive enters a geofence area; and activate a boost mode to discharge an electric energy stored in the battery to the traction motor to boost a tractive force of the ground engaging elements.

Abstract: A mechanism to determine whether conditions are correct for coupling one train consist to another train consist is disclosed. Controllers on locomotives are configured to determine the forces and/or compression state between locomotives and/or cars of a consist based at least in part on an intra-train force model and measured sensor data. The controllers also determine the relative speed of the consists that are to be joined. Based at least in part on the compressive state of at least one of the consists and the relative speed of the consists, the controller determines whether the conditions are suitable to couple the two consists. In some cases, terrain data, such as upcoming slope of tracks data may also be used in determining whether conditions are suitable for coupling consists. In further cases, the operation of at least one consist may be modified to achieve suitable conditions for coupling the two consists.

Abstract: A bearing assembly installed within a turbocharger housing between a turbine wheel and a compressor impeller mounted for rotation together on a turbocharger shaft may include a journal bearing disposed on a corresponding portion of the turbocharger shaft, a thrust bearing having a thrust bearing surface, and a bearing carrier. The bearing carrier may include a carrier body, a carrier body bore extending axially through the carrier body and receiving the journal bearing therein, and a thrust bearing seat on the exterior of the carrier body facing the turbine wheel. The thrust bearing seat may have a complimentary shape to the thrust bearing surface of the thrust bearing, the thrust bearing disposed between the carrier body and the turbine wheel and engaging the thrust bearing seat. The bearing assembly may further include an anti-thrust bearing surface facing the compressor impeller, and an anti-thrust bearing mounted to the anti-thrust bearing surface.

Abstract: A first locomotive that includes a control unit is disclosed. The control unit may receive a power demand, determine a first power limit of the first locomotive, and receive a second power limit of a second locomotive and a third power limit of a third locomotive. The control unit may proportion the power demand into a first power allocation for the first locomotive, a second power allocation for the second locomotive, and a third power allocation for the third locomotive. The control unit may adjust the first power allocation based on the first power limit, adjust the second power allocation based on the second power limit, and adjust the third power allocation based on the third power limit. The control unit may cause an action to be performed in connection with the first power allocation, the second power allocation, and the third power allocation.

Abstract: A system that includes a detection device, an imaging device, and a control device is disclosed. The detection device may generate proximity data relating to a proximity of an undercarriage of a rail vehicle, and the imaging device may capture one or more thermal images of the undercarriage. The control device may receive a first thermal image and a second thermal image of the undercarriage. The first thermal image may be captured using a first integration time, and the second thermal image may be captured using a second integration time. The control device may determine composite thermal data associated with the undercarriage. The composite thermal data may include information mapping a first range of thermal data and mapping a second range of thermal data to one or more components of the undercarriage. The control device may cause an action to be performed in connection with the composite thermal data.
