Abstract
An exhaust device for an internal combustion engine is mounted on a vehicle and equipped with an exhaust passage, a reforming catalyst and a NOx purification catalyst. The exhaust passage communicates with the engine. The reforming catalyst is provided on the exhaust passage at the upstream side of the NOx purification catalyst, and it generates the reducing agent by reforming CH. The NOx purification catalyst purifies NOx by means of the reducing agent generated by the reforming catalyst.
