    摘要: A train control system includes independent virtual in-train forces modeling engines onboard each of a plurality of locomotives in a train and a data acquisition hub configured to acquire signals from sensors, wherein the signals are indicative of real-time force and displacement measurement data from each of draft gears and couplers interconnecting each locomotive with another locomotive or with non-powered rail cars, acquire synchronized messages transmitted from offboard the train or from other locomotives of the train over a range of frequencies used by voice radios on the train for communicating between the locomotives, wherein the synchronized messages include real-time information on starting the train, stopping the train, and the next two speed limits for the train, and acquire heuristic data indicating the locomotive's motion during a predetermined period of time. An energy management system adjusts throttle requests, dynamic braking requests, and pneumatic braking requests for the locomotives based at least in part on a respective one of the virtual in-train forces models.

    摘要: A fluid level sensor is disclosed. The fluid level sensor has a frame which includes a hollow coupling component that attaches to a fluid drain of a gear case of a locomotive. A lug is insertable into the hollow coupling component that has a first connection end, and an elongated flexible sensor blade is attached to the lug. The flexible sensor blade is inserted into the gear case and used to measure a fluid level of a fluid in the gear case. The fluid level sensor also has a connector having a second connection end attached to the first connection end and a third connection end. A cover is attached to the frame, and the cover has a fourth connection end inside of an aperture of the cover, and the fourth connection end is attached to the third connection end.

    摘要: A turbine assembly for a turbocharger and method of assembling is disclosed. The turbine assembly may comprise a turbine wheel coupled to a rotatable turbocharger shaft, and a turbine housing that at least partially encloses the turbine wheel. The turbine housing may include an exhaust diffuser configured to direct a flow of exhaust, a support member coupled to the exhaust diffuser by a clamp assembly, the clamp assembly, a diffuser gap and a support gap. The clamp assembly may be disposed on the exhaust diffuser and on the support member. The clamp assembly includes a containment ring and a clamp plate. The containment ring may include a channel. The clamp plate may be disposed in the channel. The diffuser gap may be disposed between the containment ring and the exhaust diffuser. The support gap may be disposed between the containment ring and the support member.

    摘要: A railcar hatch control system and method for operating railcar hatches of a multi-railcar train is disclosed. A multi-railcar train may have a locomotive and a plurality of railcars having railcar hatches that can be opened and closed. The system and method may include displaying railcar identification information for the railcars on an operator display device, and receiving selections of railcars from an operator that will have a railcar hatch operation performed thereon, such as opening or closing the hatches. The railcar hatch operation is input, and the system and method control the railcar hatch operation being performed only on the selected railcars, and not on the railcars that have not been selected by the operator. The system and method may have operator interfaces devices at an operator station of the train, or at a remote location or on a remote device that communicates wirelessly with the train.

    摘要: A turbocharger variable speed control mechanism for a turbocharger for an engine includes a sun gear of a planetary gear set coupled to a turbocharger shaft, a planet carrier operatively connected to an engine output shaft of the engine, a brake disk coupled to and rotatable with a ring gear, and a brake actuator mechanism proximate the brake disk and mounted to a turbocharger housing. The brake actuator mechanism is selectively actuatable between a non-braking state where no braking force is applied to the brake disk so that the ring gear is free to rotate relative to the turbocharger housing, and a full braking state where a full braking force is applied to the brake disk such that the ring gear is held stationary relative to the turbocharger housing and rotation of the planet carrier is transmitted through the planetary gear set to cause rotation of the turbocharger shaft.

    摘要: 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.

    摘要: A liquid-gas separation unit of a dual-fuel engine is provided. The liquid-gas separation unit includes an exhaust conduit and a separator mounted on the exhaust conduit. The exhaust conduit has a first end and a second end distal to the first end. The first end of the exhaust conduit is coupled to a gaseous fuel supply conduit of the dual-fuel engine for receiving a leaked liquid fuel and a gaseous fuel. The leaked liquid fuel is received from at least one injector of the dual-fuel engine. Further, the separator is adapted to separate the leaked liquid fuel from the gaseous fuel before ejecting the gaseous fuel through the second end of the exhaust conduit.
