Abstract
The hydrogen engine hereof introduces water as vapor with inlet hydrogen and air, as a mixture proportioned for practical internal combustion and efficient power output. Water vapor is a substantial component of the exhaust of hydrogen fueled engines. In one embodiment of the invention, water vapor is condensed from the exhaust, and thereupon arranged to provide the input water as a continuing self-supporting process. The resultant emissions are very low in oxides of nitrogen, and readily meet the EPA Standards on pollutants as presently set for 1976. Further, and importantly, engine backfire is eliminated in the operation. Also, engine output power and efficiency are improved with the invention principles.
