摘要: Provided are exhaust systems and components suitable for use in conjunction with gasoline direct injection (GDI) engines to capture particulates in addition to reducing gaseous emission such as hydrocarbons, nitrogen oxides, and carbon monoxides. Exhaust treatment systems comprising a three-way conversion (TWC) catalyst located on a particulate trap are provided. An exemplary particulate trap is a soot filter. Additional treatment components can be added downstream of the particulate trap, including NOx traps and SCR catalysts. The TWC catalyst can be coated on both the inlet side and the outlet side of the particulate trap. Alternatively, an oxidation catalyst can be deposited on a particulate trap. Methods of making and using the same are also provided.
