摘要: An engine exhaust aftertreatment system including a bend routing an exhaust flow in a curved direction to a straight part. A nozzle is mounted in the bend to introduce a spray of a fluid with a axis of symmetry into the exhaust flow. The axis of symmetry intersects the exhaust flow traveling in the curved direction at a intersection angle of less than 50 degrees.

The system may include two or more first exhaust treatment devices, each configured to receive one of the separate entering exhaust streams in a first direction. The system may further include two or more redirecting flow passages configured to combine the separate exhaust streams into a merged exhaust stream that flows in a second direction about 180 degrees from the first direction and an intermediate flow region configured to divide the merged exhaust stream into two or more separate exiting exhaust streams. The system also may also includes two or more second exhaust treatment devices, each configured to receive one of the separate exiting exhaust streams in a third direction about 90 degrees from the second direction.
