A locomotive engine control system includes one or more processors operably connected to fuel supply devices. The fuel supply devices are configured to supply fuel into different corresponding cylinders of an engine. The one or more processors are configured to monitor a fuel quantity injected into the cylinders of the engine before and after communication of an overfuel control signal. The overfuel control signal commands the fuel supply device corresponding to a first cylinder of the cylinders to supply excess fuel into the first cylinder. Responsive to the fuel quantity that is monitored not decreasing after the communication of the overfuel control signal, the one or more processors are configured to determine that the fuel supply device corresponding to the first cylinder is defective, and may generate one or more control signals indicative of the fuel supply device corresponding to the first cylinder being defective.

Vehicle engine control system

A vehicle includes an engine and alternator having a field coil and a plurality of output windings, a field current controller configured to receive an AC input and convert the AC input into a regulated DC output that is supplied to the field coil of the alternator, and a controller configured to monitor at least one operating parameter of the field current controller and to compare a monitored value of the at least one operating parameter to a threshold range.

System and method for locomotive diagnostics

A railroad wheel reference groove locating gauge for determining a measurement of an annular reference groove machined in a face of a railroad wheel spaced radially outwardly from an axle on which the wheel is mounted a predetermined distance indicative of the wheel diameter, with the measurement being taken while the wheel remains connected to the axle, the gauge comprising an elongate member having a first end and a second end, indicia on the elongate member at the first end thereof indicative of a length along the elongate member; and an attachment element at the second end of the elongate member for detachably securing the gauge relative to an axis of rotation of the axle, with the elongate member extending radially to the first end thereof adjacent the reference groove on the wheel for enabling the use of the indicia to determine the diameter of the reference groove.
