Abstract

See full text

An NH3 supply amount controller reduces and adjusts a supply amount of NH3 to an SCR catalyst by an NH3 supplier, when an exhaust gas flowing into an NOx catalyst has a rich air-fuel ratio and NOx occluded by the NOx catalyst is reduced to N2. A reduction amount of the supply amount of the NH3 controlled by the NH3 supply amount controller is set larger when an amount of reducing agent detected or estimated by a reducing agent amount detector is larger.
