Abstract
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.
Claims20
An engine exhaust aftertreatment system comprising:
- a bend routing an exhaust flow in a curved direction;
- a straight part receiving the exhaust flow from the bend;
- and
- a nozzle mounted in the bend to introduce a spray of a fluid with a axis of symmetry into the exhaust flow wherein the axis of symmetry intersects the exhaust flow traveling in the curved direction at a intersection angle between the axis of symmetry and the exhaust flow of less than 50 degrees.
