NTIS: N82-30714 :75 pages
The National Aeronautics and Space Administration (NASA) Lewis Research Center performed an assessment of alternative power sources for the Bureau of Mines. As part of this assessment, NASA tested a 40-kw stirling research engine to evaluate its performance and emission characteristics when operated with helium working gas and diesel fuel. This report describes the engine, the test facility, and the test procedures. Performance and emission data for the engine operating with helium working gas and diesel fuel are reported and compared with data obtained with hydrogen working gas and unleaded gasoline fuel. Helium-diesel test results are compared with the characteristics of current diesel engines and other stirling engines. External surface temperature data are also presented. Emission and temperature results are compared with federal requirements for diesel underground mine engines. The durability potential of stirling engines is discussed on the basis of the experience gained during the engine tests.
