Abstract:
An exhaust emission control system is provided, which includes a NO x  storage catalyst provided in an exhaust passage of an engine and configured to store NO x , a urea SCR catalyst provided in the exhaust passage, downstream of the NO x  storage catalyst, and a NO x  reduction controlling module configured to set a NO x  reduction condition and, when the NO x  reduction condition is satisfied, performs NO x  reduction processing in which an air-fuel ratio of exhaust gas is set to be one of near a stoichiometric air-fuel ratio and rich, and the NO x  stored in the NO x  storage catalyst is reduced, the NO x  reduction condition being set looser for the NO x  reduction processing performed the first time after the engine is started than the NO x  reduction processing performed the second and subsequent times after the engine is started.

Claim (Index 1):
An exhaust emission control system, comprising:\n a NO x  storage catalyst provided in an exhaust passage of an engine and configured to store NO x ; a urea selective catalytic reduction (SCR) catalyst provided in the exhaust passage downstream of the NO x  storage catalyst; and a processor configured to execute a NO x  reduction controlling module to set a NO x  reduction condition and, when the NO x  reduction condition is satisfied, perform NO x  reduction processing in which an air-fuel ratio of exhaust gas is set to be one of near a stoichiometric air-fuel ratio and rich, and the NO x  stored in the NO x  storage catalyst is reduced, the NO x  reduction condition being set looser for the NO x  reduction processing performed a first time after the engine is started than the NO x  reduction processing performed a second and subsequent times after the engine is started.
