Power generation system and method
First Claim
1. An extended rich mode tractive power-producing engine having an intake for hydrocarbon fuel and an exhaust, said extended rich mode engine configured to produce a substantially continuous optimized hydrogen rich engine exhaust comprising hydrogen and carbon monoxide having a combined concentration of hydrogen and carbon monoxide greater than 50% by volume;
- an oxygen enrichment device having an oxygen stream effluent in fluid communication with said engine intake wherein said oxygen enrichment device is an oxygen separator, a pressure swing absorption oxygen separator, a SOFC oxygen separator, a ceramic membrane oxygen separator, or a combination thereof.

Abstract
An extended rich mode engine configured and operated extremely rich of stoichiometric to produce a substantially continuous hydrogen rich engine exhaust. Oxygen enrichment devices further optimize production of hydrogen rich engine exhaust. Engines include a free piston gas generator with rich homogenous charge compression, a rich internal combustion engine cylinder system with an oxygen generator, and a rich inlet turbo-generator system with exhaust heat recovery. Oxygen enrichment devices to enhance production of hydrogen rich engine exhaust include pressure swing absorption with oxygen selective materials, and oxygen separators such as a solid oxide fuel cell oxygen separator and a ceramic membrane oxygen separator.
