摘要： A hydrogen storage system for detecting and restricting a pressure difference generated in the hydrogen storage system and a method for adjusting differential pressure therein are provided. The hydrogen storage system includes a controller that controls valves of a plurality of tanks. The controller measures pressure for each tank, measures a pipe pressure of pipe connected with the plurality of tanks, compares the pressure for each tank with the pipe pressure to determine whether differential pressure between the tank and the pipe is generated, determines whether it is expected to generate differential pressure between the tanks in an expected equilibrium temperature, when it is determined that the differential pressure between the tank and the pipe is not generated, and performs pressure equilibrium control between the tanks, when it is expected to generate the differential pressure between the tanks.

摘要： A system for cleaning a fuel cap valve of a vehicle, may include a fuel cap having an air breather passage and a negative-pressure valve body configured for opening or closing the air breather passage; a canister for collecting evaporated gas inside a fuel tank to supply the evaporated gas into an engine intake system; and a negative-pressure control mechanism for controlling an engine negative pressure, which is applied from the engine intake system to the negative-pressure valve body of the fuel cap through the canister and the fuel tank, to reach a predetermined level or more, or for controlling the engine negative pressure at a repetition interval, in a fuel cap cleaning mode for cleaning the negative-pressure valve body of the fuel cap.
