摘要： A decomposition chamber for an aftertreatment system includes a body and a diffuser. The body includes an inlet, an outlet, a thermal management chamber, and a main flow chamber. The inlet is configured to receive exhaust gas. The outlet is configured to expel the exhaust gas. The thermal management chamber is in fluid communication with the inlet. The thermal management chamber is configured to receive an exhaust gas first portion from the inlet. The main flow chamber is in fluid communication with the inlet. The main flow chamber is configured to receive an exhaust gas second portion from the inlet and to receive the exhaust gas first portion from the thermal management chamber. The diffuser is positioned within the main flow chamber. The diffuser includes a diffuser inlet portion and a diffuser flange portion. The diffuser inlet portion includes a plurality of diffuser perforations.
