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

A comparative study of the performance of an engine operating on gasoline and on hydrogen is presented. Results indicate thermal efficiencies of from 25 to 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.
