Abstract
An exhaust component assembly includes a first exhaust component extending along a first axis, a second exhaust component extending along a second axis, and a mixer having a mixer inlet portion connected to an outlet from the first exhaust component and a mixer outlet portion connected to an inlet to the second exhaust component. A flexible connection couples the mixer inlet portion to the mixer outlet portion.
Claims23
An exhaust component assembly comprising:
- a first exhaust component extending along a first axis, the first exhaust component having an upstream end that receives engine exhaust gases and a downstream end;
- a second exhaust component extending along a second axis, the second exhaust component having an upstream end and a downstream end;
- a mixer having a mixer inlet portion connected to the downstream end of the first exhaust component to enclose the downstream end of the first exhaust component and a mixer outlet portion connected to the upstream end of the second exhaust component to enclose the upstream end of the second exhaust component such that the mixer transfers the engine exhaust gases from an outlet of the first exhaust component to an inlet of the second exhaust component;
- a first connection end extending from the mixer inlet portion toward the mixer outlet portion along a third axis;
- a second connection end extending from the mixer outlet portion toward the mixer inlet portion along the third axis and axially spaced apart from the first connection end;
- and
- a flexible connection coupling the first connection end of the mixer inlet portion to the second connection end of the mixer outlet portion.

An exhaust component assembly comprising:
- a first exhaust component extending along a first axis, the first exhaust component having an upstream end that receives engine exhaust gases and a downstream end;
- a second exhaust component extending along a second axis that is non-coaxial with the first axis, the second exhaust component having an upstream end and a downstream end;
- a mixer having a mixer inlet portion connected to the downstream end of the first exhaust component to enclose the downstream end of the first exhaust component and a mixer outlet portion connected to the upstream end of the second exhaust component to enclose the upstream end of the second exhaust component such that the mixer transfers the engine exhaust gases from an outlet of the first exhaust component to an inlet of the second exhaust component;
- a first connection end extending from the mixer inlet portion toward the mixer outlet portion along a third axis;
- a second connection end extending from the mixer outlet portion toward the mixer inlet portion along the third axis and axially spaced apart from the first connection end;
- an injector to inject fluid to mix with exhaust gas exiting the first exhaust component, wherein the injector is mounted to the mixer inlet portion;
- and
- a flexible bellows coupling the first connection end of the mixer inlet portion to the second connection end of the mixer outlet portion.
