Abstract
Methods and systems are provided for modeling a reductant temperature and storage distribution of a SCR catalyst axially and radially. In one example, a method may include modeling an expected distribution of stored reductant among a plurality of axial zones and a plurality of radial zones of an SCR catalyst arranged in an engine exhaust passage and comparing the expected distribution with a reductant storage setpoint of each zone to adjust radial and axial storage locations.
