摘要:
The working gas circulation engine includes a combustion chamber (11) 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 (20) capable of circulating gas containing the working gas from an exhaust side to an intake side of the combustion chamber (11) and resupplying to the combustion chamber (11) and provided with a removing device (40) to remove a product generated with the reaction from the circulating gas, a supplying device (30) capable of supplying the plural kinds of reactant gas to the combustion chamber (11) or the circulation route (20), a pressure detecting device (62) capable of detecting pressure in the circulation route (20), and a control unit (50) that controls supply amount of at least one kind of the reactant gas to be supplied from the supplying device (30) based on the pressure in the circulation route (20) detected by the pressure detecting device (62), and performs pressure control to adjust the pressure in the circulation route (20). Accordingly, excessive pressure variation in the circulation route can be suppressed.
