Abstract

The trend toward usage of vehicles that operate on alternative, renewable forms of energy storage has generated areas for development of new products that will facilitate implementation of new automotive fuel systems. As the reality of a hydrogen-fueled economy emerges, intermediate technologies may be necessary for the transition between hydrocarbon fueled internal combustion engines and hydrogen powered fuel cells. The University of Nevada Las Vegas Center for Energy Research has developed a method for converting the common hydrocarbon fueled internal combustion engine to hydrogen direct injected fueling. This thesis describes the second phase of development and involves the design, fabrication and characterization of a spark plug/fuel injector assembly which will allow conversion to hydrogen direct injection fueling without disassembly/modification of internal engine components. Characterization of these assemblies includes response time testing of the solenoids used and flow rate testing of the assemblies at various pressures and operational frequencies.
