GAS ENGINE LOCOMOTIVE GAS TREATMENT SYSTEM Russian patent published in 2022 - IPC B61C17/02 F17C5/02 

FIELD: machine building.

SUBSTANCE: invention relates to supply of liquefied gas to locomotives. Gas engine locomotive gas treatment system includes tank (1) for storage, transportation and supply of liquefied natural gas, safety valves (2) with discharge pipelines (3) for gas discharge, regasifier (4), gas filter (5), receiver (6), shutoff valves (7) and (8) on liquefied and gaseous fuel circulation pipelines (9) and (10), shutoff valves (11) on heat carrier pipelines (12), an additional circuit containing atmospheric evaporator (13), shutoff valves (14), cryogenic (9.1) and gas (10.1) pipelines connecting atmospheric evaporator (13) with reservoir (1). Regasifier (4), reducer (15), filter (5), receiver (6), shutoff valves (7) and (8), pipelines (9) and (10), shutoff valves (11), heat carrier pipelines (12) are combined into a module for preparation and supply of gaseous fuel to the traction section of the gas engine locomotive. Number of modules for preparation and supply of gas fuel to the traction section of the gas-engine locomotive corresponds to the number of traction sections connected to operation.

EFFECT: simplified design of gas treatment system, higher reliability.
