WORKING-GAS-CIRCULATION-TYPE ENGINE

摘要

An working-gas-circulation-type engine (1) comprising: a combustion chamber (11) in which a working gas (Ar) having a higher specific heat ratio than air can expand as fuel (H2) combusts; a circulation path (20) capable of circulating gas, which contains the working gas (Ar), from the exhaust side to the intake side of the combustion chamber (11) and again supplying the gas to the combustion chamber (11); and a control device (60) for changing, on the basis of the specific heat ratio of the gas which circulates in the circulation path (20), the control parameter for controlling the combustion of the fuel (H2). The configuration enables the working-gas-circulation-type engine (1) to achieve stable output.
