Abstract
A method (and a system that executes the method) for control of at least one sectional ammonia coverage degree profile NHfor at least one SCR catalyst included in an exhaust gas treatment system, the method includes determining at least one ammonia sectional coverage degree profile NHfor the at least one SCR catalyst based on a flow F, a temperature T and a composition C of the exhaust stream upstream of the at least one SCR catalyst. The method also includes comparing the at least one sectional ammonia coverage NHwith at least one sectional reference profile for an ammonia coverage degree NHfor the at least one SCR catalyst. The method further includes controlling, based on the comparison, at least one of a concentration of nitrogen oxides Cin the exhaust stream to be output from the combustion engine and a dosage of a reductant including ammonia NH3 to be injected into the exhaust stream upstream of the at least one SCR catalyst.
