  • Patent number: 10443524
    Abstract: An exhaust emission control system of an engine including a NOx catalyst disposed in an exhaust passage and for storing NOx within exhaust gas when an air-fuel ratio of the exhaust gas is lean, and reducing the stored NOx when the air-fuel ratio is approximately stoichiometric or rich, is provided. The system includes a SCR catalyst disposed downstream of the NOx catalyst and for purifying NOx by causing a reaction with ammonia, and a processor configured to execute a NOx reduction controlling module for controlling the air-fuel ratio to a target ratio so that the stored NOx is reduced. The controlling module limits the performance of the NOx reduction control when a temperature of the SCR catalyst is above a given temperature and loosens the limitation in a given engine operating state in which an exhaust gas flow rate is above a given rate despite the SCR catalyst temperature.
