Abstract
The authors proposed the design technique of a Stirling engine in case the limited heat source like waste heat or the biomass. In order to estimate the design technique and the engine system performance, a Stirling engine for experiments is designed. The engine is multi-stage type engine of three-step composition. When swept volume of a displacer piston and a power piston of each engine can be adjusted according to a heat source suitably, the heat source is changed to engine output efficiently.
