Hydrogen engine performance analysis project. First quarterly report, second year of program, March 1978

Objective is to obtain the design data-base covering performance, operational and emissions characteristics of prototype hydrogen-fueled, air-breathing engines for automotive use. Hydrogen-fueled internal combustion engines were divided into fourteen subgroups, and an engine representative of each subgroup will be tested. The Project Program Plan calls for investigation of pre-intake valve closing fuel ingestion (Pre IVC) hydrogen-fueled engines during the first two years. The following second-year activities have been completed: (1) construction of the 12 to 1 compression ratio engine; (2) construction of the intake manifold for the engine configuration No. 10 (Discontinuity Engine); and (3) construction of the ignition system for engine configuration No. 10. Progress has been made in the following areas: (1) construction of the cylinder head for engine configurations No. 7, 8 and 9; (2) construction of the circuitry for the digital oscilloscope; (3) compilation and initial analysis of literature regarding NO/sub x/ reducing catalysts; (4) design of the high-pressure hydrogen-fuel delivery system; and (5) selection of the single-cylinder Toyota engine configuration and initial contacts with companies who construct such engines.
