A catalytic converter system having oxygen storage materials is disclosed and methods for determining whether to reactivate oxygen storage materials and monitoring failure events of the oxygen storage materials are also disclosed.

Accelerated catalyst reactivation control strategy for gasoline vehicle emissions system in conjunction with N2 selective catalyst to minimize NOX remake

Methods are provided for emissions control of a vehicle. In one example, a catalyst may include a cerium-based support material and a transition metal catalyst loaded on the support material, the transition metal catalyst including nickel and copper, wherein nickel in the transition metal catalyst is included in a monatomic layer loaded on the support material. In some examples, limiting nickel to the monatomic layer may mitigate extensive transition metal catalyst degradation ascribed to sintering of thicker nickel washcoat layers. Further, by utilizing the cerium-based support material, side reactions involving nickel in the transition metal catalyst with other support materials may be prevented.

Exhaust treatment system including nickel-containing catalyst

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.

Methods and systems are provided for a multicomponent aftertreatment device arranged in a vehicle exhaust gas passage. In one example, a system may include an oxygen storage catalyst and an underbody trap catalyst comprising metal modified zeolite, the oxygen storage catalyst arranged upstream of the underbody trap catalyst in an exhaust passage of the vehicle.

Multicomponent exhaust treatment system including an oxygen storage catalyst

Methods and systems are provided for a steam reforming catalyst. In one example, a method may include flowing exhaust gas from a first cylinder bank directly to a three-way catalyst, flowing exhaust gas from a second cylinder bank directly to a steam reforming catalyst, and flowing exhaust gas from the steam reforming catalyst to the three-way catalyst.

Methods and systems for an aftertreatment catalyst

Phosphorus tolerant or resistant three-way catalysts (TWC) are disclosed. The TWC may include a substrate defining a plurality of channels. It may include front and rear washcoat portions overlying the substrate and having respective first and second washcoat loadings, the first washcoat loading being at most 2.0 g/inand less than the second washcoat loading. The front washcoat portion may include a catalyst material supported on a support material comprising a cerium oxide, such as ceria or CZO, or a pre-phosphated material, such as AlPO, or CePO. In one embodiment, the support material may comprise at least 85 wt. % of a cerium oxide or at least 85 wt. % of a phosphate-containing material. The front portion and the underlying substrate may comprise from 3 to 25 vol. % of the three-way catalyst or the front portion may overly up to an initial 15% of an axial length of the substrate.

A system for filtering and oxidizing particulate matter produced by a gasoline direct injection engine is disclosed. In one embodiment, engine cylinder air-fuel is adjusted to allow soot to oxidize at an upstream particulate filter while exhaust gases are efficiently processed in a downstream catalyst.

Method for controlling fuel of a spark ignited engine while regenerating a particulate filter

A three-way catalyst including a mixture of nickel and copper is provided for reducing carbon monoxide, hydrocarbon emissions, and nitrogen oxides from vehicle engine exhausts. The catalyst is impregnated onto a carrier substrate which is non-reactive with nickel and copper. When used in a vehicle exhaust gas treatment system, the nickel-copper catalyst provides improved efficiency in reducing CO, HC, and NOemissions over the use of conventional three-way-catalysts and provides enhanced oxygen storage capacity (OSC) and water-gas-shift (WGS) functions.

Fuel control for spark ignited engine having a particulate filter system

A nickel-based catalyst is provided for reducing carbon monoxide, hydrocarbon emissions, and nitrogen oxides from vehicle exhausts. The catalyst is impregnated directly onto a carrier which is non-reactive with nickel. The nickel is contained on said carrier at a loading of between about 2 to about 20 wt %. When used in a vehicle exhaust gas treatment system, the catalyst provides improved efficiency in reducing CO, HC, and NOemissions over the use of conventional three-way-catalysts.

Exhaust treatment system including a nickel-based catalyst

A method for controlling an internal combustion engine wherein, during an initial, relatively low temperature operating phase of the engine, the engine operates with a modulated air/fuel ratio established independently of the operating condition of the engine and wherein, during a subsequent higher temperature operating phase of the engine, the air/fuel ratio is modulated in as a function of the operating conditions of the engine.
