Abstract
An SCR system includes at least one catalyst, and an intake conduit. The intake conduit includes an intake conduit first sidewall, at least a portion of which defines a first curvature. An intake conduit second sidewall is coupled to the intake conduit first sidewall so as to define the intake conduit. A catalyst is fluidly coupled to the intake conduit through the intake conduit second sidewall. The intake conduit second sidewall is inclined at a first angle with respect to a longitudinal axis of the SCR system, such that an intake conduit second end cross-section of the intake conduit is smaller than an intake conduit first end cross-section. An intake conduit third sidewall is positioned at the intake conduit second end. The intake conduit is structured to produce an even flow split of the exhaust gas through the intake conduit internal volume towards the catalyst.
