Methods and systems are provided for a flow device shaped to adjust flow to radial positions of an emission control device. In one example, a system may include where the flow device comprises a plurality of inner openings that align while a plurality of outer openings are misaligned to flow exhaust gas proximal to a central axis of an exhaust passage, and where the plurality of outer openings are aligned and the plurality of inner openings are misaligned to flow exhaust gas distal to the central axis.

Methods and systems for adjusting exhaust gas flow through an aftertreatment device

Methods and systems are provided for an exhaust-gas aftertreatment device. In one example, an exhaust-gas aftertreatment device comprises a housing with a first can comprising a first catalytic converter and a second can comprising a second catalytic converter, wherein the first catalytic converter is not concentric with the first can.

Systems and methods for an exhaust-gas aftertreatment device

Methods and systems are provided for an exhaust tract for vehicles having an internal combustion engine, the exhaust tract including a first exhaust gas aftertreatment device and a metering device arranged downstream therefrom. In one example, a region of the first exhaust gas aftertreatment device which is situated downstream is designed as an SCR region. Further, the metering device is designed to spray a reducing agent onto a side of the first exhaust gas aftertreatment device which faces the metering device, counter to a main direction of flow of an exhaust gas.

Exhaust tract having a metering device which sprays counter to a direction of flow, method for operating an exhaust tract and vehicle having an exhaust tract

An arrangement of an internal combustion engine with at least one first and one second nitrogen oxide storage catalytic converter is provided, wherein the first nitrogen oxide storage catalytic converter is arranged within a low-pressure exhaust gas recirculation circuit. A method for operating the arrangement is furthermore provided, wherein the nitrogen oxide storage catalytic converters can be used for the production of ammonia under operating conditions with a high load by providing rich exhaust gas conditions.

System and method for exhaust gas aftertreatment with lean NOx trap and exhaust gas recirculation

Systems are provided for an exhaust gas aftertreatment device, in particular in a motor vehicle, having a catalyst accommodated in a housing which, along its length, has a first end section, a catalyst section, and a connecting section. The housing further comprising a particulate filter located downstream of the catalyst.

Methods and systems for an exhaust aftertreatment device

A method for controlling exhaust gas aftertreatment in an exhaust gas aftertreatment system having at least one nitrogen oxide storage catalyst and at least one catalyst for selective catalytic reduction is provided, wherein, in phases of a high load, a combustion engine is operated with a substoichiometric fuel/air mixture, and nitrogen oxides in the exhaust gas are reduced in the nitrogen oxide storage catalyst to ammonia, which is stored in the catalyst for selective catalytic reduction, and, when the storage capacity of the catalyst for selective catalytic reduction is exceeded, the combustion engine is operated with a superstoichiometric fuel/air mixture, thus allowing nitrogen oxides in the catalyst for selective catalytic reduction to be reduced by the stored ammonia.

Methods and systems for treating vehicle emissions

Methods and systems are provided for an exhaust gas aftertreatment system. In one example, a method may include limiting ammonia desorption from a catalyst in response to an increase in driver demand by activating an electric motor.

Methods and systems for an exhaust gas aftertreatment system

An operating method for a motor vehicle having a hybrid drivetrain includes, during a demand check, comparing at least one value which characterizes a current state of an exhaust-gas after-treatment device, with a setpoint value of the exhaust-gas after-treatment device. In response to the comparison indicating a deviation of the value characterizing the current state of the exhaust-gas after-treatment device from the setpoint value, a demand for a measure is indicated. The measure includes supplying charge gas, which includes recirculated exhaust gas, to the internal combustion engine during overrun operation. In addition, a capability check is carried out to detect conditions suitable for implementing the operating method.

Methods relating to exhaust after-treatment devices

Methods and systems are provided for an exhaust gas aftertreatment system for a combustion engine in a motor vehicle. In one example, the exhaust gas aftertreatment comprises at least two catalyst devices arranged in an exhaust tract, and a feed device for a reducing agent arranged between the two catalysts, and which furthermore comprises a first heat device at the inlet of the first catalyst and a second heat device downstream thereof, the system adapted for the reduction of nitrogen oxides.
