Examples for a traction system are provided. In one example, the traction system includes a nozzle coupled to an air source and configured to be selectively aimed toward a determined portion of a rail surface of a rail, and a conduit configured to supply pressurized air from the air source to the nozzle, the nozzle flexibly coupled thereto. The nozzle is configured for the aim of the nozzle to be controlled to change its aiming direction in response to a change in curvature of the rail, whereby a stream of air from the nozzle impacts the determined portion during movement of the vehicle through the curvature of the rail.

Damping members for turbocharger assemblies, methods for providing turbocharger assemblies, and turbocharger assemblies are described herein. The damping members include bodies having shapes to fit between a recess extending into a rotor disk of a turbocharger and laterally protruding shoulders of platforms in neighboring blades of the turbocharger. The bodies dampen vibrations of the blades during rotation of the blades. The damping members may include a variety of shapes, such as a sheet, a wedge, a tapered pin, a cylindrical pin, a bent sheet, or another shape.

Underplatform damping members and methods for turbocharger assemblies

Various methods and systems are provided for calibrating one or more exhaust valves. In one example, a system comprises an exhaust valve configured to control flow of exhaust gas exiting an engine and a controller configured to calibrate the exhaust valve by commanding the exhaust valve to a fully closed position with a first driving current and measuring a first position of the exhaust valve at the first driving current, commanding the exhaust valve to a fully open position with a second driving current and measuring a second position of the exhaust valve at the second driving current, and generating a map based on a linear function determined from the first driving current, the second driving current, the measured first position, and the measured second position. The controller is further configured to adjust a position of the exhaust valve based on the map.

Method and system for calibrating exhaust valves

A control system receives signals representing a presence and position of a secondary movement system onboard a vehicle. The secondary movement system changes movement of the vehicle without generating thrust or propulsion to move the vehicle. The control system creates a schedule of use of the secondary movement system based on the presence and position of the secondary movement system and controls the secondary movement system based on the schedule that is created.

Vehicle control system and method

A system for controlling a consist of rail vehicles or other vehicles includes a control unit electrically coupled to a first rail vehicle in the consist, the control unit having a processor and being configured to receive signals representing a presence and position of one or more tractive effort systems on-board the first vehicle and other rail vehicles in the consist, and a set of instructions stored in a non-transient medium accessible by the processor, the instructions configured to control the processor to create a optimization schedule that manages the use of the one or more tractive effort systems based on the presence and position of the tractive effort systems within the consist.

Adhesion control system and method

Various methods and systems are provided for detecting a change in turbocharger performance. In one example, a method comprises determining a level of turbocharger imbalance based on output from a turbine speed sensor and generating a signal related to a change in a performance level of the turbocharger if the level of turbocharger imbalance is greater than a threshold.

Methods and system for a turbocharger

An aerodynamic control system includes a skirt assembly configured to be disposed between plural vehicles in a vehicle system formed from the plural vehicles with the vehicles separated by a spatial gap in the vehicle system. The skirt assembly can include a bladder configured to be inflated with a fluid by a fluid source disposed onboard the vehicle system to cause the skirt assembly to expand between the vehicles from a collapsed state to an expanded state such that the skirt assembly at least partially fills the spatial gap between the vehicles. The skirt assembly can reduce aerodynamic drag exerted on the vehicle system during movement of the vehicle system relative to the vehicle system moving without the skirt assembly in the expanded state.

Aerodynamic control system and method

Various methods and systems are provided for controlling a tip clearance between a shroud and blade of a turbocharger turbine. In one embodiment, a method for an engine including a turbocharger comprises, selectively adjusting a flow of coolant from one or more engine coolant sources through a shroud of a turbine based on a tip clearance between the shroud and a blade of the turbine.

Various methods and systems are provided for diagnosing individual engine cylinders based on a turbocharger speed fluctuation of a turbocharger. In one embodiment, a method for an engine includes adjusting engine operation based on an indicated operating parameter of an individual engine cylinder, where the indicated operating parameter is based on at least one turbocharger speed fluctuation of a turbocharger correlated with crankshaft position.

Method and system for adjusting engine cylinder operation

Various methods and systems are provided for controlling air flow in a two-stage turbocharger. In one example, an engine method comprises adjusting one or more exhaust gas recirculation valves to maintain a first turbocharger within a first air flow range, and adjusting a turbocharger bypass valve to maintain a second turbocharger within a second air flow range.

Methods and system for controlling surge in a two-stage turbocharger

Various methods and systems are provided for detecting turbocharger degradation. In one example, a method comprises detecting an axial position of a turbine rotor based on output from a turbine speed sensor, and if the axial position is greater than a threshold distance from a base position, indicating turbocharger degradation.

Methods and system for detecting turbocharger degradation

A monitoring system and method monitor changes in clearance distances between a sensor and a rotating component of a machine. Imbalance and/or wear in the machine is identified based on the changes in the clearance distances. The system and method optionally both measure the clearance distances and a rotating speed of the rotating component of the machine with the same sensor. In order to identify imbalance in the machine, a spectral energy of the machine can be calculated based on the changes in the clearance distances, and the imbalance in the machine can be identified based on the spectral energy. The system and method can determine a trigger speed of the machine that is associated with the wear in the machine based on the changes in the clearance distance. A remaining useful life of the machine can be estimated based on changes in the trigger speed.
