An early task under the contract requires the contractor to prepare a series of conceptual Stirling engine system designs intended to meet the final program objectives, and to submit the initial conceptual designs, supporting analyses and recommendations to the NASA Project Manager for review and approval. The recommended Stirling engine concept should be the one which has the greatest chance of successfully meeting the final program objectives, within the capabilities, schedule and budget of the Program. The report summarizes the studies that were made, the methodology that was used and the results which support the concluded recommendation of a: Four cylinder, double acting, and square U design, with external regenerators. Optimization of this design concept resulted in a calculated fuel economy of 36.3 mpg for a 3200 pound vehicle, compared to the program goal of 30.0 mpg., and acceleration time of 13.1 seconds compared to the program goal of 15.0 seconds. The engine will meet or exceed the program emission goals of HC . 0.41 gram/mile, CO . 3.4 gram/mile, and NO/sub x/ . 0.4 gram/mile.
