About scientific developments in the field of application of gas systems for traction engines in railway transport
The article considers the retrospective and current economic and technological state of the domestic and foreign market of traction rolling stock manufacturers on gas engine fuel. Stimulating and limiting factors affecting the introduction of gas engine technology in railway transport are given. The advantages and disadvantages of the introduction of gas engine technology in railway transport are described, as compared to the options for transferring diesel locomotives to gas during gas turbine and gas diesel cycles. The results of the feasibility study of the gasification of the diesel locomotive fleet of the Sverdlovsk Railway are shown, showing that the greatest economic effect is achieved by the joint transfer to gas of the main and shunting locomotives operating on the gas diesel cycle. The results of full-scale and computational studies aimed at a comparative risk assessment for various types of gas delivery to traction engines and the improvement of the staffing systems for fire and explosion safety, as well as the safe evacuation of liquefied natural gas vapors, are described. Proposals have been developed to improve the safety of gas locomotives.
