摘要： 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.

摘要： Various example embodiments relate to a system that includes a nozzle. A dosing line is connected to the nozzle and a fuel dosing module. The fuel dosing module is in fluid communication with the dosing line and includes an outlet in fluid communication with the dosing line. An air inlet is positioned upstream of the outlet and is configured to receive air. A fuel inlet is positioned upstream of the outlet and is configured to receive fuel. A fuel valve is positioned upstream of the outlet and downstream of the fuel inlet and is configured to control the flow of fuel. The fuel dosing module is configured to combine the fuel and the air upstream of the outlet and downstream of the fuel valve to generate an air-fuel fluid, wherein the air-fuel fluid removes particles from the nozzle.
