Abstract: Systems and methods for controlling a gasoline urea selective catalytic reductant catalyst are described. In one example, an observer is provided that corrects an estimate of an amount of NH3 that is stored in a SCR. The amount of NH3 that is stored in the SCR is a basis for generating additional NH3 or ceasing generation of NH3.

Abstract: Methods and systems are provided for emissions control of a vehicle. In one example, an emissions treatment device includes a porous substrate and a catalytic washcoat disposed thereon, the catalytic washcoat having nickel and no other metal. The porous substrate may be configured to filter particulate matter (PM) exiting the vehicle and the catalytic washcoat may be configured to oxidize at least a portion of the PM. The nickel in the catalytic washcoat may provide additional oxygen storage capacity and increased tolerance to sulfur poisoning of catalytic activity of the catalytic washcoat, further promoting PM oxidation. Moreover, because the catalytic washcoat may increase PM oxidation during passive regeneration events, a total number of active regeneration events may be decreased and fuel economy may be maintained.

Abstract: A particulate filter for use in a vehicle engine exhaust is provided which includes a catalyst containing a mixture of nickel and copper. The catalyst is impregnated into the filter substrate, which is non-reactive with nickel and copper. When used in a vehicle exhaust gas treatment system, the catalyst on the filter improves soot burn-off at low temperatures, provides improved efficiency in reducing CO and NOx emissions over the use of conventional three-way-catalyst washcoats, and provides enhanced oxygen storage capacity (OSC) and water-gas-shift (WGS) functions.

Abstract: A hydrocarbon trap is provided for reducing cold-start hydrocarbon emissions. The trap comprises a monolithic flow-through substrate having a porosity of at least 60% and including a zeolite loading of at least 4 g/in3 in or on its walls. A separate coating of a three-way catalyst is provided over the zeolite coating. The trap may further include an oxygen storage material. The hydrocarbon trap may be positioned in the exhaust gas system of a vehicle such that unburnt hydrocarbons are adsorbed on the trap and stored until the monolith reaches a sufficient temperature for catalyst activation.
