Abstract: An exhaust gas cleaning system for an engine capable of judging the amount of trapped NOx and the oxygen storage capacity of an NOx trap agent and which can diagnose the deterioration of the NOx trap agent. The NOx trap is arranged in an exhaust gas passage and the air-fuel ratio of the exhaust gas is temporally changed from a lean air-fuel ratio to the stoichiometric air-fuel ratio or a rich air-fuel ratio with a predetermined cycle. The NOx trapping occurs by absorbing or adsorbing NOx in the exhaust gas when an air-fuel ratio of the exhaust gas is a lean air-fuel ratio and by releasing or reducing NOx when the air-fuel ratio is a rich air-fuel ratio. The amount of trapped NOx is judged from the oxygen concentration and the oxygen concentration in the exhaust gas is detected in the exhaust gas passage in the downstream side of the NOx trap and determined by taking the oxygen storage capacity when the air-fuel ratio of the exhaust gas changes to the stoichiometric air-fuel ratio or the rich air-fuel ratio.
