摘要： An aftertreatment module for use with an engine is disclosed. The aftertreatment module may have a plurality of inlets configured to direct exhaust in a first flow direction into the aftertreatment module. The aftertreatment module may also have a mixing duct configured to receive exhaust from the plurality of inlets, and a branching passage in fluid communication with the mixing duct. The branching passage may be configured to redirect exhaust from the mixing duct into separate flows that exit the aftertreatment module in a second flow direction opposite the first flow direction.

摘要： An exhaust muffler for an internal combustion engine, the exhaust muffler including a housing having a first end plate and a second end plate. The second end plate is disposed opposite to the first end plate. The exhaust muffler also includes an inlet pipe connected to the first end plate and an outlet pipe connected to the second end plate of the housing. A plurality of passages are disposed within the housing along a longitudinal axis of the housing, the plurality of passages have different lengths.

摘要： An engine exhaust aftertreatment component includes a housing defining an exhaust flow from an exhaust inlet to an exhaust outlet. An exhaust aftertreatment substrate is positioned within the housing between the exhaust inlet and the exhaust outlet and has an upstream face, which includes an inner region surrounded by an outer region. A flow distributor is positioned in the housing upstream from the exhaust aftertreatment substrate and divides the exhaust flow into a first portion directed toward the inner region through a first set of perforations and a second portion directed toward the outer region serially through a second set of perforations and a third set of perforations.
