Special bayonet-type heat exchangers whose inner tubes move inside of the outer tubes, were applied for the engine's heater and cooler. An annular regenerator was located in a displacer piston. The engine had already achieved the target performance. To improve the engine performance efficiently, a simulation model for the prototype engine was developed. The pressure in the working space was analyzed by an isothermal analysis which takes into account a gas leakage between the buffer space and working space, and a pressure losses in the heat exchangers. For the pressure loss in the regenerator, the model can treat the effects by the velocity distribution in the regenerator matrix. To estimate the engine output, the model calculates the mechanical loss and the buffer loss which is caused by a pressure change in the buffer space. The buffer loss was calculated with three models, an isothermal, an adiabatic and a simple heat transfer model to determine a suitable model for the buffer space. The analysis results were compared with the experimental deta carefully.
