Abstract
An exhaust emission control device is disclosed. The device includes an NO-occlusion reduction catalyst incorporated in an exhaust passage for reduction and purification of NO, a fuel reforming catalyst structure and plasma fuel reforming unit for decomposition of the fuel into Hand CO is arranged in the exhaust passage upstream of the reduction catalyst, so that the fuel is decomposed into Hand CO such that NOon the surface of the NO-occlusion reduction catalyst can be efficiently reduced into N. Thus, high NOreduction ratio can be always obtained irrespective of variety of operational conditions.
