Abstract

PURPOSE:To improve handling performance and facilitate operation by performing the closure of the exhaust valves in the fuel system and the oxidant system by means of the monitor signal from the battery voltage at a start of the battery. CONSTITUTION:When start switch is pushed at the time t0, nitrogen feeding valve 12 and nitrogen discharge valve 15 are opened, and nitrogen flows through the nitrogen system. At the time t1, fuel-nitrogen selector valve 16 and oxidant-nitrogen selctor valve 17 are operated, and at the same time, fuel discharge valve 13 and oxidant discharge valve 14 are opened, and then nitrogen flows through the fuel system, oxidant system, fuel chamber 2, and oxidant chamber 3. At the time t2, fuel feeding valve 10 and oxidant feeding valve 11 are opened, and at the same time the operation of fuel-nitrogen selector valve 16 and oxidant-nitrogen selector valve 17 are brought into stop, and then fuel flows into the fuel system and the fuel chamber 2, and oxidant flows into the oxidant system and the oxidant chamber 3. At the time t3, the battery voltage is monitored by a monitor circuit, and the fuel discharge valve 13 and oxidant discharge valve 14 are closed by a signal from the circuit.
