Abstract
An exhaust gas aftertreatment device for an internal combustion engine comprises a housing, first and second catalytic substrates arranged inside the housing such that the first catalytic substrate is arranged upstream of the second catalytic substrate, and a reductant injector arranged in between the first and second catalytic substrates. Further, the first and second catalytic substrates are arranged such that a fluid flow direction through the exhaust gas aftertreatment device is angled. A flow redirecting wall is arranged downstream of the first catalytic substrate such that the fluid flow between the first and second catalytic substrates at least partially passes an outer circumference of the first catalytic substrate before reaching the second catalytic substrate. The redirecting wall is inclined to an outlet surface of the first catalytic substrate and the reductant injector is arranged at the redirecting wall at a position distant from the outlet surface.
