Hydrogen-engine performance-analysis project. Fourth quarterly report, December 1979

Progress is reported in a project aimed at obtaining a data base covering performance, operational characteristics and emissions essential for making a rational decision regarding the selection and design of prototype hydrogen-fueled, air-breathing engines capable of being manufactured for general automotive use. The project program plan calls for investigation of preintake valve closing ingestion (Pre IVC) hydrogen-fueled engines. During the quarter the following were accomplished: the high pressure hydrogen delivery system has been designed and is being constructed; the single cylinder engine has been constructed; construction of the cylinder head and injector for the Post IVC engine continues; and an NH/sub 3/ analyzer has been installed, but is not functioning properly.
