Abstract
Methods and systems are provided for an exhaust-gas aftertreatment device. In one example, an exhaust-gas aftertreatment device comprises a housing with a first can comprising a first catalytic converter and a second can comprising a second catalytic converter, wherein the first catalytic converter is not concentric with the first can.
Claims19
A system, comprising:
- an exhaust-gas aftertreatment housing comprising a first can comprising a first catalytic converter and a second can comprising a second catalytic converter, the first can arranged upstream of the second can, wherein the first catalytic converter comprising a diameter smaller than a diameter of the first can, and wherein the first catalytic converter is pressed against an interior surface of the first can.
An exhaust-gas treatment apparatus, comprising:
- a housing comprising a first can comprising a first catalytic converter and a second can comprising a second catalytic converter, the first can arranged upstream of the second can, wherein a second can diameter is larger than a first can diameter, the first can diameter being larger than a first catalytic converter diameter, wherein a central axis of the first catalytic converter is misaligned with a central axis of the first can.
A vehicle, comprising:
- an engine fluidly coupled to an exhaust passage;
- an aftertreatment housing arranged along the exhaust passage, the aftertreatment housing comprising a first can and a second can fluidly coupled to one another;
- a first catalytic converter arranged in the first can and a second catalytic converter arranged in the second can, the first can arranged upstream of the second can, wherein the first catalytic converter is pressed against an interior surface of the first can to maximize a space between the first catalytic converter and the second can;
- and
- a thermally-insulating device arranged between a first wall of the first can and a second wall of the second can, wherein the first wall is opposite the interior surface and corresponds to a wall of the first can nearest the second can.
