CRYOGENIC FUEL SUPPLY SYSTEM FOR ENGINE FEED Russian patent published in 2017 - IPC B61C5/00 B60K15/00 F02M21/02 

FIELD: engines and pumps.

SUBSTANCE: proposed cryogenic fuel supply system for the engine feed is located on two sections of the locomotive, interconnected by an intersection connection 4, and comprises a cryogenic tank 1 for storing liquefied cryogenic fuel, a voluminous cryogenic high pressure pump 3, an oil heat exchanger 5, a gas heat exchanger 6, a gas mixer 7, a gas receiver 8, a fuel filter 9, a controlled gas dispenser 10, pipelines 22-25, valves 18-21, controlled by a control unit 17 valves 12-16. Between the cryogenic tank 1 and the cryogenic pump 3 an intermediate buffer 2 is installed.

EFFECT: location optimisation of the cryogenic fuel supply pipelines, reduction of the preparation time for work and transfer to the storage mode of the cryogenic fuel supply system, increasing the reliability of the cryogenic fuel supply system, reducing the time for repair and maintenance of the locomotive.
