Abstract: According to one aspect of the present disclosure, a method of controlling an exhaust gas recirculation (EGR) system of an engine system includes determining a first EGR command according to a first method during a steady state engine condition, determining a second EGR command according to a second method during a transient engine condition, wherein the first method is based at least in part on values from a NOx sensor, and the second method is not based on values from a NOx sensor. The method further includes adjusting an EGR valve of the EGR system based on the first EGR command during the steady state engine condition, and adjusting the EGR valve based on the second EGR command during the transient engine condition.

Abstract: A weight shifting mechanism for a bogie frame is provided. The weight shifting mechanism may include an axle support pivotally coupled to the idler axle, a pusher link pivotally coupled to the axle support and forming a first fulcrum with the bogie frame, a support member pivotally coupled to the pusher link and the axle support, and an actuator mounted on the support member and actuatably coupled to the axle support via a live lever and a connector link. The live lever may form a second fulcrum with the support member and may be pivotally coupled to the connector link. The connector link may be pivotally coupled to the axle support. The actuator may selectively pivot the live lever about the second fulcrum to pivot the axle support about the idler axle and move the bogie frame relative to the idler axle.

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 monitoring system for a train is provided. The monitoring system includes an image capturing device configured to capture a video feed of a designated area associated with the train. The monitoring system also includes a controller coupled to the image capturing device. The controller is configured to receive the video feed from the image capturing device. The controller is configured to analyze the video feed to determine if a predefined triggering event has occurred. The controller is configured to record and store a predefined length of the video feed based on the determination. The controller is configured to provide a notification of the recorded video feed to a user through a user interface. The controller is configured to allow the user to access at least a portion of the recorded video feed through the notification.

Abstract: A valve assembly of a fuel supply system includes a first body defining a first bore, an inlet port to receive fuel into the first bore, and an outlet port. The valve assembly further includes a pneumatic chamber disposed in fluid communication with the first bore. The valve assembly further includes a first piston to move between a first position and a second position. The first piston restricts and allows flow of fuel from the inlet port to the outlet port, in the first position and the second position, respectively. The valve assembly further includes a vent passage located upstream of the pneumatic chamber and configured to receive fuel leaked from a flow path defined between the inlet port and the outlet port. The valve assembly also includes a check valve disposed in the vent passage and configured to selectively vent the fuel entering the vent passage.

Abstract: A visual diagnostic system for a rail vehicle having multiple assets is disclosed. The visual diagnostic system may have a data interface configured to receive a data stream from a wayside unit. The data stream includes values of a plurality of parameters measured made by the wayside unit. The data interface may also be configured to receive geo-information and configuration-information. The system further includes a memory device configured to store the data stream and a controller configured to determine, from the geo-information and the configuration-information, a geographic location of each of the multiple assets. The controller is further configured to determine prognostic information associated with an operational status of each of the multiple assets. The controller may further render for display in a user interface a visual representation of the rail vehicle with the prognostic information for each asset of the rail vehicle.
