A selective catalytic reduction system may include a single housing defining a single centerline axis. The selective catalytic reduction system may also include a diesel particulate filter disposed within the single housing and having a DPF center axis aligned with the single centerline axis. The selective catalytic reduction system may also include an SCR catalyst disposed within the single housing and having a center axis aligned with the single centerline axis. In some implementations, the diesel particulate filter may include one or more SiC filters. In some implementations, the SCR catalyst may include one or more extruded SCR catalysts.

Single module integrated aftertreatment module

An exhaust aftertreatment assembly and method of manufacturing and operating an exhaust aftertreatment assembly. An exhaust aftertreatment assembly includes an aftertreatment housing and an inlet conduit coupled to the aftertreatment housing at an inlet port so as to transfer exhaust gas into the aftertreatment housing. An inlet chamber is positioned in the aftertreatment housing. The inlet chamber is fluidly coupled to the inlet port of the aftertreatment housing to receive the exhaust gas from the inlet conduit.

Compact side inlet and outlet exhaust aftertreatment system

Described herein are various embodiments of a reductant decomposition system. According to one representative embodiment, the reductant decomposition system includes an exhaust gas chamber including an inlet and outlet. The system also includes a first exhaust gas distribution component positioned within the chamber and communicable in exhaust gas receiving communication with the outlet. The first exhaust gas distribution component causes swirling exhaust gas flow patterns within the exhaust gas chamber. Additionally, the system includes a second exhaust gas distribution component positioned within the chamber and communicable in exhaust gas providing communication with the inlet. The second exhaust gas distribution component includes features that cause a swirling exhaust gas flow pattern within a space defined by the second exhaust gas distribution component. Further, the system includes a reductant injector coupled to the exhaust gas chamber. The reductant injector is communicable in reductant injecting communication with exhaust gas within the chamber.

Reductant decomposition system

An apparatus for designing a tubing configuration comprising modules that receive tube design input, interpret a tube design input, calculate a final tube design, and display a final tube design. The tube design input may include point locations, bend criteria and end conditions, among others. The apparatus may further include modules that determine whether the tube design input exceeds a complexity threshold, comprises a minimum set of information, and comprises a conflicting or erroneous design. The apparatus may further include modules that determine and optimize the manufacturing cost as well as determine the manufacturability of the tube. The apparatus may further include modules that store operational challenges corresponding to emissions reduction features and secondary components.
