Wayne G Wnuck, Ke Liu: CPO regenerated lean NOx trap with no moving parts. HydrogenSource, M P Williams, October 18, 2005: US06955042 (26 worldwide citation)

A single lean NOx trap (8) has an inlet manifold (10) with baffles (18–20) to divide the inlet manifold into three flow paths (11–13). Each flow path has a thermal reformer (24–26; CPO, (POX, or ATR) with an electric heater provided electric power by related lines (29–31). Fuel from a source (50) is ...

Edwin Yue Bun Pun, Ke Liu: Method for fabricating buried ion-exchanged waveguides using field-assisted annealing. City University of Hong Kong, Heslin Rothenberg Farley & Mesiti P C, November 20, 2012: US08312743 (12 worldwide citation)

A method for forming buried ion-exchanged waveguides involves a two-step process. In a first step a waveguide is formed at the surface of a substrate using an ion-exchange technique. After formation of the waveguide, a field-assisted annealing is carried out to move the waveguide away from the surfa ...

Ke Liu, Wayne G Wnuck, Willem P Leenhouts: Intermittent application of syngas to NOx trap and/or diesel engine. HydrogenSource, M P Williams, November 15, 2005: US06964156 (9 worldwide citation)

A catalytic partial oxidizer (30) provides syngas (hydrogen and carbon monoxide) to an apparatus intermittently using syngas such as valves (34) feeding NOx traps (35), for brief periods of time. During turndown times when syngas is not being used, either the output of the CPO is diverted (33) to th ...
