Exhaust gas purification device for internal combustion engine |
| abstract |
An object of the present invention is to obtain a high NO X purification rate at a low temperature. A use of alumina base point on the support surface as a catalyst carrier of the exhaust purification catalyst 11 for purifying under NO X lean air-fuel ratio is present. On an alumina surface, to be supported by dispersing platinum without forming a layer of the NO X absorbent capable of absorbing the NO X. The air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst 11 is temporarily switched from lean to rich before the entire surface of the platinum is subjected to oxygen poisoning.
