摘要 |
An object of the present invention is to provide an exhaust gas purifying apparatus for an internal combustion engine which can successfully achieve a good balance between reduction of exhaust emission and removal of particulate matter PM. An upstream side three-way catalyst 18 without OSC materials is disposed in an exhaust pipe 14 immediately below an exhaust manifold 12 of an internal combustion engine 10. A particulate filter (PM filter) 20 for trapping the particulate matter PM contained in exhaust gas is disposed at a downstream side of the upstream side three-way catalyst 18. A downstream side three-way catalyst 22 with the OSC materials is disposed at a downstream side of the PM filter 20. |
