Exhaust gas purification apparatus for internal combustion engine |
| abstract |
An exhaust gas purification apparatus for an internal combustion engine capable of lean operation has an Ir-containing selectively reducing catalyst and an NOx adsorptive catalyst. The Ir-containing selectively reducing catalyst in which iridium is an active species thereof and NOx is selectively reduced in a lean atmosphere by HC as a reducer is disposed in an exhaust system of the internal combustion engine. The Ir-containing selectively reducing catalyst is disposed on an upstream side of the exhaust system. The NOx adsorptive catalyst adsorbs NOx in the lean atmosphere and reduce the adsorbed NOx at a theoretical air-fuel ratio or at a rich air-fuel ratio. The NOx adsorptive catalyst is disposed on a downstream side of the exhaust system. |
