Abstract: An energy recovery system for a power system is disclosed. The power system includes an engine, a generator driven by the engine, an electrical bus configured to receive electrical power from the generator, an exhaust conduit configured to receive exhaust gases from the engine, and a turbocharger coupled to the exhaust conduit. The energy recovery system includes a bypass conduit, a turbo-generator, and a synchronizer. The bypass conduit is coupled to the exhaust conduit, and facilitates a portion of exhaust gases from the exhaust conduit to bypass the turbocharger. The turbo-generator is coupled to the bypass conduit, and is driven by the portion of exhaust gases bypassing the turbocharger. Further, the synchronizer modulates one or more parameters of electrical power received from the turbo-generator based on one or more parameters of electrical power present on the electrical bus. The synchronizer transmits modulated electrical power to the electrical bus.

Abstract: A cleaning device for a pressure sensor associated with an engine system includes a one-way valve having an inlet side and an outlet side. The outlet side is in selective fluid communication with an inlet of the pressure sensor. The cleaning device also includes a compressed air source in selective fluid communication with the one-way valve. The cleaning device further includes a control module communicably coupled to each of the pressure sensor, the one-way valve, and the compressed air source. The control module is configured to control an operation of the one-way valve and the compressed air source to impart at least one of a long burst of modulated air and a short burst of modulated air on the inlet of the pressure sensor.

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.
