ABSTRACT:
A working gas circulation engine includes a combustion chamber that can expand a working gas, which has a specific heat ratio higher than that of the air, with the combustion between an oxidizing agent and a fuel; a circulation path that can allow the working gas to circulate from a suction side to an exhaust side of the combustion chamber and can supply the same again to the combustion chamber; a feed means that can feed the gas in a pressure-reduction target section, which is the section whose pressure is to be reduced, to the outside, and a control means that operates the feed means for feeding the gas in the pressure-reduction target section, when the pressure in the pressure-reduction target section is higher than a predetermined pressure that is set in advance.
