With a target of developing a Stirling engine to be driven by waste heat of refuse incinerators etc. with the working gas such as sir or nitrogen, a displacer type engine was made on experimental basis, and its performance was tested. Air and nitrogen are cheaper and easier to handle than helium or hydrogen which is generally used as the working gas, but the flow resistance of the gas of such a kind is fairly higher than that of helium. In order to reduce the flow resistance, special perforated copper heat-transmitters were adopted as heater elements and regenerator matrices. Conveniently, the welding job required for making the heater of this type is comparatively little. The test showed almost satisfactory performance of the engine. However, it became clear that in order to raise the mean working pressure still more, the gas-seal device for the power piston should be much improved.
