Abstract:
1. A working gas circulation engine comprising: a combustion chamber to which plural kinds of reactant gas and working gas having a higher specific heat ratio than air are supplied and in which the working gas is expandable corresponding to reaction of the plural kinds of reactant gas; a circulation route configured to circulate gas containing the working gas from an exhaust side to an intake side of the combustion chamber and resupplying to the combustion chamber and provided with a removing device to remove a product generated with the reaction from the circulating gas; a supplying device configured to supply the plural kinds of reactant gas to the combustion chamber or the circulation route; a pressure detecting device configured to detect pressure in the circulation route; and a control unit configured to perform pressure control to adjust the pressure in the circulation route by controlling a supply amount of at least one kind of the reactant gas to be supplied from the supplying device based on the pressure in the circulation route detected by the pressure detecting device.
