Abstract: An exhaust aftertreatment system including a selective catalytic reduction device (SCR), a NOx sensor and a reductant injection system is described. A method for controlling the reductant injection system to inject reductant into the exhaust gas feedstream upstream relative to the SCR includes monitoring engine operation, and determining an initial reductant dosing rate responsive to the engine operation. A dosing perturbation is induced in the reductant dosing rate. The exhaust gas feedstream is monitored via the NOx sensor, and a reductant dosing correction term is determined based upon the monitoring. A final dosing rate for controlling the reductant injection system is determined based upon the initial reductant dosing rate, the dosing perturbation, and the reductant dosing correction term

Abstract: A method for controlling a vehicle including an exhaust aftertreatment system for purifying exhaust gases from a compression-ignition engine includes monitoring vehicle operating parameters, determining whether the vehicle is stopped, determining whether the engine is commanded off, and determining whether the exhaust aftertreatment device is at a predetermined operating temperature. When the vehicle is stopped, the engine is commanded off and the exhaust aftertreatment device is at the predetermined operating temperature the engine is controlled in a run-on state for a predetermined period of time. The run-on state includes operating the engine in a throttled and fueled state.

Abstract: A Cu-amine complex of hydrated copper sulfate and ethylene diamine or an oligomer of ethylene diamine is employed in a direct (one-pot) synthesis of a copper-cation containing silicoaluminophosphate (SAPO) zeolite material having the Cu/SAPO-34 structure. The copper-amine complex is included in an aqueous gel of precursors of the SiO2, Al2O3, and P2O5 constituents, which are mixed, aged, and thermally treated to form the desired Cu/SAPO-34 structure. The synthesized Cu/SAPO-34 material is demonstrated to be an effective catalyst material in conversion of nitric oxide to nitrogen (using ammonia as a reductant) in synthetic exhaust streams characteristic of diesel engine and other lean-burn vehicle engine exhaust streams.

Abstract: Nitrogen oxides (NOx), carbon monoxide (CO), and residual hydrocarbons are adsorbed and stored from a low temperature, cold-start, diesel engine (or lean-burn gasoline engine) exhaust stream by a combination of a silver-based (Ag/Al2O3) NOx adsorber material and a zeolite-platinum group metal (zeolite-PGM) adsorber material for low temperature temporary storage of the NOx. The combination of NOx adsorber materials is formed as separate washcoats on channel walls of an extruded flow-through monolithic support. The monolith is located near the exhaust manifold of the lean burn engine where the combination of NOx adsorber particles temporarily adsorb exhaust constituents, and commence oxidation of them, until the progressively warming exhaust stream removes the stored constituents and carries them through the exhaust pipe to downstream NOx reduction converters which have been heated to their operating temperatures and complete the conversion of the NOx constituents to nitrogen and water for discharge from the vehicle's exhaust system.
