Exhaust gas purification device for internal combustion engine |
| abstract |
The present invention provides an exhaust emission control device for an internal combustion engine that can reliably purify exhaust gas with a simple structure even when the temperature of a catalyst is low. A low temperature HC trap catalyst layer (26c) containing an HC trap agent capable of trapping HC at a low temperature and a low temperature NOx adsorption catalyst layer (26d) containing a NOx adsorbent capable of adsorbing NOx at a low temperature. Are stacked on the gasoline particulate filter (26b), and the downstream gasoline particulate filter (26b) in the exhaust flow direction of the low temperature HC trap catalyst layer (26c) and the low temperature NOx adsorption catalyst layer (26d). ), A PM combustion catalyst layer (26e) containing a noble metal such as rhodium (Rh) is supported to form a multifunctional catalyst (26). Then, the air-fuel ratio is controlled based on the multifunctional catalyst temperature Tm. [Selection] Figure 2 |
