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.

Abstract: Presented are control systems for operating rechargeable electrochemical devices, methods for making/using such systems, and vehicles with intelligent battery charging and charging behavior feedback capabilities. A method of operating a rechargeable battery includes an electronic controller receiving battery data from a battery sensing device indicative of a battery state of charge (SOC). Using this battery data, the controller determines a number of low SOC excursions at which the battery SOC is below a predefined low SOC threshold and a number of high SOC excursions at which the battery SOC exceeds a predefined high SOC threshold. The controller then determines if the number of low SOC excursions exceeds a predefined maximum allowable low excursions and/or the number of high SOC excursions exceeds a predefined maximum allowable high excursions. If so, the controller responsively commands a resident subsystem to execute a control operation that mitigates degradation of the rechargeable battery.

Passivating can include heating, optionally in the presence of steam. The gamma-phase alumina can be lanthanum-doped gamma-phase alumina and can be about 0.1-55 wt. % lanthanum. The catalytic metal can include rhodium, copper, or nickel. The catalytic metal can be rhodium or nickel, and the catalytic metal can be applied to the passivated theta-phase alumina support body at a loading of about 0.1-10 wt. %. The catalytic metal can be copper, and the catalytic metal can be applied to the passivated theta-phase alumina support body at a loading of about 0.1-30 wt. %. The gamma-phase alumina support body can be at least about 90 wt. % gamma-phase alumina. The passivated theta-phase alumina support body can be at least about 80 wt. % theta-phase alumina.

Abstract: Technical methods described herein include an emissions control system for treating exhaust gas from an internal combustion engine in a motor vehicle. The emissions control system includes a three-reaction oxygen storage model. The system further includes a three-way catalyst and a controller that controls an oxygen storage level for the three-way catalyst. The controller determines a first reaction rate representing a net rate of cerium oxidation by oxygen, a second reaction rate representing a net rate of cerium reduction by carbon monoxide, and a third reaction rate representing a net rate of cerium reduction by hydrogen. The controller further determines the oxygen storage level based on the first reaction rate, the second reaction rate, and the third reaction rate.

Abstract: Methods of preparing a sinter-resistant catalyst include forming a dual coating system. A surface of a particulate catalyst support contacts a first liquid precursor including a metal salt with an element selected from the group consisting of: aluminum (Al), cerium (Ce), zirconium (Zr), titanium (Ti), silicon (Si), magnesium (Mg), zinc (Zn), and combinations thereof. The first liquid precursor precipitates or is adsorbed as an ion on a portion of the surface forming a first coating including a porous metal oxide on the surface. The surface may be contacted with a second liquid precursor including a metal oxide sol including a metal selected from the group consisting of: aluminum (Al), cerium (Ce), zirconium (Zr), iron (Fe), titanium (Ti), silicon (Si), and combinations thereof. A second coating is formed from the second liquid precursor on a portion of the surface to create the sinter-resistant catalyst system.

Abstract: A method for exhaust aftertreatment includes determining a diagnostic condition with respect to a threshold diagnostic condition, determining an SCR efficiency as a ratio of a readout of a first NOx sensor at a first NOx sensing position with respect to a readout of a second NOx sensor at a second NOx sensing position, the first NOx sensing position located about an engine out area within an exhaust stream before a DOC and the second NOx sensing position located about an output of an SCR device within the exhaust stream; and comparing the SCR efficiency to a threshold SCR efficiency range. If the SCR efficiency is less than the threshold SCR efficiency range, then trigger DOC failure for NO oxidation, and if the SCR efficiency is greater than or equal to the threshold SCR efficiency range, then DOC is determined to be operating within specifications.
