Control an internal combustion engine


In a control apparatus for an internal combustion engine in which processing of regenerating the nox storage capacity of an nsr catalyst is carried out in accompany with processing of diagnosing an abnormality in an exhaust gas purification device including the nsr catalyst, the present invention is intended to suppress the fluctuation of torque at the time of regenerating the nox storage capacity of the nsr catalyst, and to terminate abnormality diagnostic processing quickly. According to the invention, by setting an engine air fuel ratio, which has been set to a lean air fuel ratio before the processing of regenerating the nox storage capacity of the nsr catalyst is started, to a weak lean air fuel ratio which is lower than a basic lean air fuel ratio and higher than a stoichiometric air fuel ratio, it becomes possible to suppress the fluctuation of torque at the time of regeneration processing being started, and to terminate abnormality diagnostic processing at an early period of time..
