A wheel slip recovery method for a locomotive in which an internal combustion engine is connected in driving relationship to an electric power generator to supply electric power to a plurality of electric traction motors coupled to drive corresponding wheel-axle sets of the locomotive. The locomotive system includes a dynamic braking function in which an electrical resistance circuit is selectively coupled in parallel circuit arrangement with the generator for selectively receiving power from the traction motors during dynamic electrical braking. The inventive method detects a wheel slip condition which cannot be overcome by transfer of power from a slipping to a non-slipping wheel and selectively couples the dynamic braking resistance circuit into circuit with the power generator in a manner to reduce power supplied to the driven wheels to a level sufficient to allow the wheels to cease slipping without reducing power output from the generator.

Tractive effort control method and system for recovery from a wheel slip

A ramp car for use in an intermodal train includes a ramp having a set of rail wheels mounted at one end and a connector at the one end for coupling the ramp car to a flat bed rail car. A second connector, including lifting apparatus, is operatively associated with a second end of the ramp car opposite the one end for coupling the ramp car to a locomotive. A coupling apparatus is provided at the second end of the ramp car for coupling to the locomotive to permit both raising and lowering the second end and pushing and pulling the ramp car. The second connector is disconnected from the ramp car when the ramp is in a lowered position. The second connector includes a rotatable pin mounted to the locomotive and extending vertically downward and having a pair of circumferentially spaced shoulders for bearing upwardly against a supporting surface on the ramp car to hold the ramp in a raised position. The pin is rotated to lock the ramp car to the rail car.

Rail transportable ramps for loading semi-trailers on trains

A stanchion for supporting a semi-trailer for transport on a bed of a rail car comprises a generally vertically-oriented support member having a base end and a top end, with a fifth wheel mounted to the top end. A diagonal strut attached to the support member extends angularly downward. A first plate member is positioned on the rail car bed and has a first pin extending therethrough and into the rail car bed for pivotally attaching the plate member to the rail car. A second pin extends through the plate member and into the rail car bed to prevent rotation of the plate member about the first pin. Flanges on a top surface of the plate member are attached to the support member and the strut, allowing orientation of the fifth wheel to be reversed by rotating the plate member about the first pin. The stanchion may include a second plate member attached to the top end of the support member beneath the fifth wheel, with the fifth wheel being pivotally mounted to the second plate member so that the fifth wheel is independently reversible.

A fuel injection nozzle has an outer body member and an inner body member, the inner body member being slidingly positioned in a secondary axially extending cavity in the outer body member and including a valve needle slidingly positioned in a primary axially extending cavity in the inner body member. The inner body member acts as a first fluid pressure actuated valve needle for injecting fluid between the inner member and the outer member when the inner member is displaced axially by fluid pressure. The valve needle acts as a second fluid pressure actuated valve member for injecting fluid through an extension of the second axially extending cavity when the valve needle is displaced axially by other fluid pressure. First fluid orifices extend through an end of the outer member for spraying fuel released by displacement of the inner body member. Second fluid orifices extend through an end of the inner member for spraying fuel released by displacement of the valve needle.

Two-stage fuel injection nozzle

Apparatus and a method of introducing a primary fuel, which may be a coal water slutty, and a high combustion auxiliary fuel, which may be a conventional diesel oil, into an internal combustion diesel engine comprises detecting the load conditions of the engine, determining the amount of time prior to the top dead center position of the piston to inject the main fuel into the combustion chamber, and determining the relationship of the timing of the injection of the auxiliary fuel into the combustion chamber to achieve a predetermined specific fuel consumption, a predetermined combustion efficiency, and a predetermined peak cylinder firing pressure.

Method of combustion for dual fuel engine

An electrical propulsion control system for self-propelled earthmoving traction vehicles of the type having integral earthmoving means and having a prime mover-driven electric generator supplying energy to traction motors, wherein the electrical output of the generator is regulated within predetermined maximum limits which are reduced in response to the application of a predetermined lifting force to the earthmoving means.
