This paper describes in detail the experimental and theoretical results of a new type of Stirling engine with a pendulum-type displacer (PDSE) that is suspended by a hinge shaft and swings in a displacer space. The main features of PDSE are its simplicity, ease of outside gas sealing, and lower mechanical friction than that of the conventional-type Stirling engine. However, gas leakage inside the displacer is larger than that of the conventional type. The power required to induce a pendulum-type displacer motion, which consists of flow loss powers of multiple fin gas passage and regenerator wire mesh, is analyzed using a simple equation. It has been clarified that the calculated theoretical power output agreed well with the experimental power output. It has also been clarified that the measured Nusselt number of the regenerator agreed with that of a previous study. It is hoped that PDSE can be employed to utilize naturai heat energy sources in the future.
