【 摘 要 】

Hydrogen Internal Combustion Engine (HICE) technology takes advantage of existing knowledge of combustion engines to provide a means to power passenger vehicle with hydrogen, perhaps as an interim measure while fuel cell technology continues to mature. This project seeks to provide data to determine the reliability of these engines. Data were collected from an engine operated on a dynamometer for 1000 hours of continuous use. Data were also collected from a fleet of eight (8) full-size pickup trucks powered with hydrogen-fueled engines. In this particular application, the data show that HICE technology provided reliable service during the operating period of the project. Analyses of engine components showed little sign of wear or stress except for cylinder head valves and seats. Material analysis showed signs of hydrogen embrittlement in intake valves.
