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.

Abstract: An EGR cooler may include an EGR cooler housing having top, bottom and side walls, inlet and outlet end walls disposed at opposite ends, and a longitudinal axis extending in a direction of exhaust gas flow from the inlet end to the outlet end. A plurality of cooling tubes extend through the EGR cooler between the top and bottom walls, and are arranged in a cooling tube array to form an exhaust gas receiving area at an upstream side of the cooling tube array proximate the inlet end wall so that exhaust gas flowing into the EGR cooler through an exhaust gas inlet opening will flow into the exhaust gas receiving area and then disperse through the cooling tube array. A pitch distance between the cooling tubes may be greater proximate the longitudinal axis than proximate the side walls to promote flow through, instead of around, the cooling tube array.

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: An apparatus for testing installation of a network equipment onboard a locomotive of a consist is disclosed. The apparatus includes a housing and a test network equipment is disposed within the housing. The test network equipment includes a first port to connect with an output port of the locomotive via a Multiple Unit (MU) cable. The apparatus includes a user interface to connect with a second port of the test network equipment. The test network equipment establishes a communication with the user interface based on a predefined attribute of the user interface. Upon establishing the communication between the test network equipment and the user interface, the user interface is configured to identify the network equipment, establish one or more communication routes with the network equipment, and determine a status of installation of the network equipment onboard the locomotive using the one or more communication routes.

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 valve bridge is disclosed for use with an internal combustion engine. The valve bridge may include a body with a central cavity formed in a center portion of the body for receiving a hydraulic lash adjuster, and opposing first and second lateral extensions on opposite sides of the central cavity. The valve bridge may further include a first bore in the first extension for receiving a first valve stem, and a second bore in the second extension for receiving a second valve stem. The valve bridge may also include a first internal groove in a wall of the central cavity configured to receive fluid, as well as a first internal passage in the body that extends from the first internal groove toward the first bore. In addition, the first internal passage may extend from a higher gravitational point within the body to a lower gravitational point within the body.
