Abstract: The cryogenic fuel supply system for an engine is arranged in locomotive two sections connected by an inter-section connection for the purpose of transferring fuel from one section to the other. There is a cryogenic reservoir for storage of a liquefied cryogenic fuel, a positive-displacement high-pressure cryogenic pump, an oil heat-exchanger, a gas heat-exchanger, a gas mixer, a gas receiver, a fuel filter, a controlled gas metering unit, pipelines, valves, controlled valves, and a control unit. The cryogenic fuel supply system further includes an intermediate buffer arranged between the cryogenic reservoir and the positive-displacement high-pressure pump and connected to the cryogenic reservoir by pipelines and to the positive-displacement high-pressure cryogenic pump by a pipeline and two additional pipelines.

Abstract: The cryogenic gas equipment unit designed for arrangement and operation of the gas treatment system for locomotives. The unit includes a sheet-lined housing with a power rack. An upper portion of the unit housing has a shape geometrically following the shape of the inner surface of the locomotive body roof. A flooring made of a cold-resistant heat-insulating material is attached to the bottom inside the unit. An aperture is made in one of the side walls of the unit housing. Temperature deformation compensators for cryogenic fuel lines and the cryogenic equipment unit housing are installed in the entry and exit points of the cryogenic fuel lines on the unit housing. A routine inspection of the equipment in the cryogenic gas equipment unit may be carried out through the aperture. In case a piece of the cryogenic gas equipment in the unit fails, the whole unit may be removed and replaced.
