Abstract
A working gas circulation type engine includes a combustion chamber in which a working gas having a ratio of specific heats higher than that of air can be expanded by combustion of a fuel, a circulation path capable of circulating a gas containing the working gas from a gas exhaust side to a gas suction side of the combustion chamber and supplying the gas containing the working gas to the combustion chamber again, and a control device that changes a control parameter for controlling the combustion of the fuel based on a ratio of specific heats of the gas circulating in the circulation path. Therefore, there can be provided the working gas circulation type engine capable of obtaining a stable output.
