Abstract: The intersection connection of locomotive cryogenic systems includes a flexible double-wall corrugated pipeline having two corrugated pipes made of cold-resistant steel, which are arranged one inside the other and separated by elastic inserts. There are end adapter flanges fixed to the end walls of the locomotive adjacent sections, and an elastic bar connected to the flexible double-wall corrugated pipeline with suspensions. The intersection connection can be provided with an elastic bar aligned relative to the inner corrugated pipe with centering elastic inserts.

Abstract: The method effects control upon engines, in particular to regulating power of a gas-turbine-generator system used in gas-turbine locomotives, hybrid locomotives, etc. A control signal for the fuel metering unit actuator is formed by an electronic engine control system on the basis of processing of a signal from a turbine rpm sensor and a design value of the generator active electric output power. The system power can be preset. A preset power value is compared to a real power calculated value which is obtained according to measured values of current and voltage. An obtained difference is taken as the basis for forming a control signal for the fuel metering unit actuator in order to provide a certain turbine rpm and a control signal for a current regulator supplying energy to the generator excitation winding in accordance with the load curve of the gas turbine-generator system.

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 device for separating gas fraction from a liquefied natural gas flow carries out a two-stage separation of a gas fraction. The device includes a cylindrical housing provided with an inlet pipeline and an outlet pipeline, and a perforated partition arranged within the housing so as to face the outlet pipeline. The housing has two (upper and lower) portions of cylindrical shape that are connected to each other at an angle ? of 135°-170°. There are two additional pipelines on the outside, one of them being used for pressure feed of a gas fraction after the first separation stage into the housing upper portion, and the other additional pipeline being used for extracting a gas fraction after the second separation stage into the gas cavity of a reservoir containing a cryogenic fuel.
