Thanks to its special properties for the use of renewable energy, the Stirling engine is in greater demand than ever today. This book explains the technical and thermodynamic fundamentals of these machines as well as various methods for their cycle process calculation (ideal process and Schmidt analysis). These provide the design guidelines for the construction of such engines. The results of the presented analysis methods are evaluated and discussed based on measurement results from a test machine. The book also addresses the interesting variant of low-temperature Stirling engines.
