description The invention provides a method for processing a galloping fault of a diesel engine of an internal combustion locomotive and a fuel system. The fuel system comprises a first solenoid valve (2), a vent pipeline, a second solenoid valve (4) and an electric control device used for controlling the first solenoid valve (2) and the second solenoid valve (4). The first solenoid valve (2) is arranged on a fuel supply pipeline and located between a safety valve (1) and a fuel injection pump. The vent pipeline is used for delivering high-pressure gas and is arranged on one side of the fuel supply pipeline and communicated with the fuel supply pipeline, and the communication position is located between the first solenoid valve (2) and the fuel injection pump. The second solenoid valve (4) is arranged in the position, close to the fuel supply pipeline, of the vent pipeline. The method comprises the steps of blocking the fuel supply pipeline between the safety valve (1) and the fuel injection pump and introducing the high-pressure gas into the fuel supply pipeline between the first solenoid valve (2) and the fuel injection pump, wherein the pressure of the high-pressure gas is higher than the set pressure of an overflow valve (6) on a fuel return pipeline.
