The switching voltage and response time of the main valve 201 and the sub valve 202 of the fuel valve 200 under no load and load (fuel valve inlet pressure 3.15 MPa) were checked. The voltage is switched by the measurement and control device 400, and the fuel valve is not loaded (inlet pressure 0 MPa) at first.
