Mod II Engine Performance

THE AUTOMOTIVE STIRLING ENGINE PROGRAM (ASE) is directed at the development of a kinematic Stirling engine for automotive use. This program is sponsored by the Department of Energy (DOE) and managed by the NASA-Lewis Research Center (NASA-LeRC). Following proof-of-concept testing and development of promising performance values with early versions of the Stirling engine, a production-type automotive design, the Mod II engine, was developed. The design of this engine and its systems has been previously presented (1,2)*. Based on this design, the first engine has been built and development testing has started. Projections for this first engine build are presented in this paper. Results of initial tests are also given including identification of development items and formulation of plans for resolution of existing deficiencies.
