The invention provides a hydrogen-doped oxygen-enriched combustion method and device for a diesel engine and a railway vehicle. In the device and the method, an electronic control unit is connected with an environment monitoring system capable of acquiring an external environment signal. The vehicle-mounted hydrogen and oxygen preparation and storage system is in signal connection with the electronic control unit and connected with a traction braking device of the vehicle, and therefore hydrogen and oxygen are prepared and stored through electric energy of the traction braking device in the deceleration braking process of the vehicle. The vehicle-mounted hydrogen and oxygen preparation and storage system is connected with a hydrogen nozzle and an oxygen linear electromagnetic valve which are installed on a diesel engine air inlet pipe, and therefore the diesel engine can be controlled to achieve oxygen-enriched combustion by adjusting the opening degree of the oxygen linear electromagnetic valve in the operation process of a vehicle under the low-oxygen-concentration condition; the diesel engine is controlled by starting and adjusting the opening degree of the hydrogen nozzle to achieve hydrogen-doped combustion. In addition, the hydrogen nozzle is arranged between the oxygen linear electromagnetic valve and the diesel engine, so that the operation safety of the diesel engine is improved.
