Abstract
The invention relates to an exhaust aftertreatment system (1) for a combustion engine (110), comprising, an outer casing (2) comprising at least one exhaust gas inlet (3) and at least one exhaust gas outlet (4), at least one catalyst (6, 6′) being located in an inner volume (5) of the outer casing (2), wherein the system (1) is configured such that during use of the system (1) exhaust gas flows from the at least one exhaust gas inlet (3) at an inlet velocity, through the at least one catalyst (6, 6′) at a catalyst velocity, into the inner volume (5) outside the at least one catalyst (6, 6′) and to the at least one exhaust gas outlet (4), and further such that the exhaust gas flows in the inner volume (5) outside the at least one catalyst (6, 6) through at least one cross sectional area (A) being defined and limited by at least a perimeter surface (61, 61′) of the at least one catalyst (6, 6′) and an inner surface (21) of the outer casing (2) or by at least two catalyst parameter surfaces (61, 61′), wherein the at least one cross sectional area (A) is sized such that during use of the system (1) the exhaust gas flows through the at least one cross sectional area (A) at a first inner…
