<p>Inlet air (15) humidified in an air bubbling (or other) humidifier (35) that receives water from a tank (36) is sent to a hydrogen generator (27) along with vaporized (23) diesel fuel (22) to produce hydrogen and carbon monoxide ((28) for either (a) mixing with the mainstream of exhaust (18) fed to a catalytic converter (30) or (b) regenerating a pair of Nox adsorption traps (38, 39), thereby reducing oxides of nitrogen (Nox), to provide system exhaust (32) which may have less than 0.40 grams/bhp/hr of Nox and 0.28 grams/bhp/hr of non-methane hydrocarbons. In another embodiments, unhumidified air mixed with fuel feeds a homogeneous non-catalytic partial oxidizer (27) to provide the required hydrogen and carbon monoxide.</p> |
