Abstract

The invention provides a fuel mode switching system for a double-fuel locomotive and a switching method of the fuel mode switching system. The double-fuel locomotive comprises an engine, an engine electronic injection controller and an LNG tank. The switching system comprises a liquid supply cut-off valve, a gasifier, a safety valve, a gas inlet electromagnetic valve, a blow off valve, a methane detection system and a locomotive microcomputer. By means of the fuel mode switching system for the double-fuel locomotive and the switching method of the fuel mode switching system, safety guarantee control over the double-fuel locomotive is achieved, and safety of the mode switching of the double-fuel locomotive is improved to a great extent.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a dual-fuel locomotive fuel mode switching system and a switching method thereof. Background technique [0002] The dual-fuel locomotive prototype manufactured by our company is the first locomotive powered by methane gas in China. At present, there is no relevant dual-fuel locomotive safety assurance system control strategy technology at home and abroad. [0003] One of the fuels used by dual-fuel locomotives is highly flammable natural gas, so it is very necessary for the safety protection of locomotives. The purpose of this control strategy is to detect and prevent LNG / CNG from being stored, gasified, and transmitted on LNG / CNG locomotives. Leakage during the process, so as to ensure that the locomotive can run normally and safely, and ensure the personal safety of drivers and passengers. Contents of the invention [0004] In order to solve the above proble...
