Although thermal efficiency of moderate temperature differential (MTD) Stirling engines is higher than
low temperature (LTD) engines, the complexity of design of MTD engines has led to the lack of research
in this field. In this work, a prototype of Ɣ-type moderate-temperature differential Stirling engine was
manufactured, evaluated and structurally optimised. A mathematical evaluation was carried out based
on a finite-dimension thermodynamics approach. The swept volume ratio was optimised based on the
temperature difference of 450 .𝐶
0
. A computer program was thus written to simulate the Stirling engine
performance under the assumed working conditions. Based on the mentioned temperature difference,
the swept volume ratio of the engine was found to be 3. The engine dimensions were then adjusted to
fulfil the computed swept volume ratio. The bore and stroke for power piston were chosen as 60 mm
and 40 mm, respectively. For the displacer, they were selected as 90 mm and 60 mm, respectively
based on the chosen swept volume ratio.
