Abstract: An aftertreatment module may include a housing with an inlet port and an outlet port. A selective catalytic reduction catalyst may be disposed between the inlet port and the outlet port. A diffuser plate may be disposed downstream of the inlet port and upstream of the selective catalytic reduction catalysts. The diffuser plate may include a first section including a first degree of porosity and a second section including a second degree of porosity. The first degree of porosity may be greater than the second degree of porosity.

Abstract: An exhaust aftertreatment system includes a housing including at least one exhaust aftertreatment component. The housing defines a body portion and an outlet portion terminating in an outlet opening. The outlet portion decreases in diameter from the body portion toward the outlet opening. A sampling tube is positioned within the outlet portion and extends between opposing sides of an inner wall of the outlet portion, with the sampling tube having a plurality of openings facing the body portion. A NOx sensor is positioned in fluid communication with an interior of the sampling tube.
