Abstract
A first NOadsorption materialexhibiting a peak temperature being 200° C. or less at which an elimination amount of adsorbed NObecomes the maximum is put in place on an exhaust-gas upstream side, and a second NOadsorption materialexhibiting a peak temperature surpassing 200° C. at which an elimination amount of adsorbed NObecomes the maximum is put in place on an exhaust-gas downstream side of the first NOadsorption material. In low-temperature region, NOare adsorbed on the first NOadsorption material; and, in high-temperature region, NOhaving been eliminated from the first NOadsorption materialare adsorbed on the second NOadsorption materialagain. Therefore, it is possible to adsorb NOform low-temperature region and up to high-temperature region efficiently, and thereby an amount of NObeing discharged from an NOreduction catalyst to be put in place on a downstream-side thereof is reduced.
