A Hydrogen Fuelled Automobile-Australian Research
Published January 01, 1982 by SAE Australasia in Australia
This paper describes the culmination of many years of research, accelerated in recent years with Australian Government support, aimed at the development and demonstration of a viable hydrogen fuelled urban motor vehicle using Iron-Titanium-Manganese hybride fuel storage. Continued development of the delayed port admission system of hydrogen supply to the engine, coupled with combustion bomb studies of lubricating oil deposit pre-ignition behaviour and engine combustion chamber material studies have overcome the hydrogen engine backfire problem for all but extreme engine operating conditions. Inlet port water injection, during the seldom-used extreme operating conditions, enabled backfire free operation at high load and efficiency to be achieved. This engine development is described in detail, including the spark timing, fuel flow, and water injection control systems that are peculiar to hydrogen fuelled engines.
The paper will also report the experimental determination of the Fe-Ti-Mn alloy thermal and hydriding performance and the combined engine-fuel tank design and performance.
