<p>A single valve (23, 50) directs engine exhaust (11, 12) toward alternative nitrous oxide traps (19, 20) which are adjacent to either diesel particulate filters (40, 41) or low temperature water gas shift catalysts (63, 64). Syngas is either provided from a source (54) or by in-line catalytic partial oxidizers (23, 24) which may have diesel oxidation catalysts ahead of them in the flow and which receive fuel from the engine fuel source (26) through nozzles (27, 28).</p> |
