Studies Pertaining to Hydrogen Car Development. Part B. A Comparative Study of Engine Performance with Gasoline and Hydrogen. Part C. Hydrogen Storage and Flow System,

摘要

A comparative study of the performance of an engine operating on gasoline and on hydrogen is presented. Results indicate thermal efficiencies of from 25to 100% greater with hydrogen than with gasoline. The emission of nitrogen oxides was reduced approximately 90% when operating on hydrogen. With quality-governed,hydrogen operation,however,maximum power output is reduced by as much as 50%;with water injection,the figure might be 30%. The problem of the storage of hydrogen is addressed. In particular,metal hydride and liquid systems are compared. A liquid hydrogen system was developed and installed in a 1973 Jeep. Details of the system are presented. It was found to be basically feasible and operating experience thus far is favorable.
