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 other embodiments, unhumidified air mixed with fuel feeds a homogeneous non-catalytic partial oxidizer ( 27 ) to provide the required hydrogen and carbon monoxide. |
