Beschreibung
Zusammenfassung:	The invention discloses a fuel gas pressure control system of a hydrogen internal combustion engine, which relates to the hydrogen internal combustion engine and comprises a primary mechanical pressure regulator, a secondary mechanical pressure regulator and a pressure compensation device, the input end of the first-stage mechanical pressure regulator is connected with a hydrogen gas tank through a pipeline, the output end of the first-stage mechanical pressure regulator is connected with the input end of the second-stage mechanical pressure regulator through a pipeline, the output end of the second-stage mechanical pressure regulator is connected with a gas rail through a pipeline, and a pressure feedback connector of the second-stage mechanical pressure regulator is connected with the output end of the pressure compensation device through a pipeline. The actual air pressure demand value of the air rail is obtained according to the operation condition of the hydrogen internal combustion engine, and air press
