Abstract
An end cap module for a vehicle exhaust system is comprised of an outer skin and inner skin that cooperate to define an internal cavity. The outer skin includes a mount interface configured for attachment to a vehicle structure. A cast internal sub-structure is mounted within the internal cavity. The inner skin positioned within the internal cavity such that the cast internal sub-structure is positioned between the inner skin and the outer skin.

An end cap module for a vehicle exhaust system comprising:
- an outer skin defining an internal cavity, wherein the outer skin includes a base to face a vehicle structure positioned on one side of the base, the base including a mount interface configured for attachment to the vehicle structure;
- a first connection interface configured to attach to a first exhaust component;
- a second connection interface configured to attach to a second exhaust component, the first and second connection interfaces positioned on an opposite side of the base from the vehicle structure;
- a cast internal sub-structure mounted within the internal cavity, wherein the cast internal sub-structure comprises a solid plate;
- and
- an inner skin positioned within the internal cavity such that one side of the solid plate fits against the inner skin and an opposite side of the solid plate fits against the outer skin, wherein the inner skin defines an exhaust gas passageway, and wherein the outer skin, cast internal sub-structure, and the inner skin are secured together to form an end cap that connects an outlet from one of the first and second exhaust components to an inlet of the other of the first and second exhaust components.
An end cap module for a vehicle exhaust system comprising:
- an outer skin including at least a first outer skin portion and a second outer skin portion, the first outer skin portion including a base to face a vehicle structure positioned on one side of the base, the base including a mount interface configured for attachment to the vehicle structure, and the second outer skin portion defining a first connection interface configured to attach to a first exhaust component and a second connection interface configured to attach to a second exhaust component, the first and second connection interfaces positioned on an opposite side of the base from the vehicle structure;
- a cast internal sub-structure supported by the first outer skin portion, wherein the cast internal sub-structure comprises a solid plate;
- and
- an inner skin mounted between the first outer skin portion and the second outer skin portion to define an open and unobstructed exhaust gas passageway that extends between the first and second connection interfaces, and wherein the solid plate has one side that fits against the inner skin and an opposite side that fits against the first outer skin portion.
An end cap module for a vehicle exhaust system comprising:
- an outer skin including at least a first outer skin portion and a second outer skin portion, the first outer skin portion including a base to face a vehicle structure positioned on one side of the base, the base including a mount interface configured for attachment to the vehicle structure, and the second outer skin portion defining a first connection interface configured to attach to a first exhaust component and a second connection interface configured to attach to a second exhaust component, the first and second connection interfaces positioned on an opposite side of the base from the vehicle structure;
- a cast internal sub-structure supported by the first outer skin portion;
- an inner skin mounted between the first outer skin portion and the second outer skin portion to define an open and unobstructed exhaust gas passageway that extends between the first and second connection interfaces, and wherein the cast internal sub-structure is positioned between the inner skin and first outer skin portion, and wherein the inner skin is comprised of at least a first inner skin portion and a second inner skin portion, the first inner skin portion including an internal skin surface that defines the exhaust gas passageway, and the second inner skin portion including a first opening aligned with the first connection interface and a second opening aligned with the second connection interface in the second outer skin portion;
- and
- a first layer of insulation between the cast internal sub-structure and the first inner skin portion and a second layer of insulation between the second outer skin portion and the second inner skin portion.
A vehicle exhaust system comprising:
- a catalytic converter;
- an exhaust pipe;
- and
- an end cap module that connects the catalytic converter to the exhaust pipe, the end cap module comprising
- an outer skin including at least a first outer skin portion and a second outer skin portion, the first outer skin portion including a base to face a vehicle structure positioned on one side of the base, the base including a mount interface configured for attachment to the vehicle structure, and the second outer skin portion defining a first connection interface to the catalytic converter and a second connection interface to the exhaust pipe, the first and second connection interfaces positioned on an opposite side of the base from the vehicle structure,
- a cast internal sub-structure mounted to the first outer skin portion, wherein the cast internal sub-structure comprises a solid plate, and
- an inner skin mounted between the first outer skin portion and the second outer skin portion to define an exhaust gas passageway that extends between the first and second connection interfaces, wherein the solid plate has one side that fits against the inner skin and an opposite side that fits against the first outer skin portion.
A vehicle exhaust system comprising:
- a catalytic converter;
- an exhaust pipe;
- and
- an end cap module that connects the catalytic converter to the exhaust pipe, the end cap module comprising
- an outer skin including at least a first outer skin portion and a second outer skin portion, the first outer skin portion including a base to face a vehicle structure positioned on one side of the base, the base including a mount interface configured for attachment to the vehicle structure, and the second outer skin portion defining a first connection interface to the catalytic converter and a second connection interface to the exhaust pipe, the first and second connection interfaces positioned on an opposite side of the base from the vehicle structure,
- a cast internal sub-structure mounted to the first outer skin portion,
- an inner skin mounted between the first outer skin portion and the second outer skin portion to define an exhaust gas passageway that extends between the first and second connection interfaces, wherein the cast internal sub-structure is positioned between the inner skin and first outer skin portion, and wherein the inner skin is comprised of at least a first inner skin portion and a second inner skin portion, the first inner skin portion including an internal skin surface that defines the exhaust gas passageway, and the second inner skin portion including a first opening aligned with the first connection interface and a second opening aligned with the second connection interface in the second outer skin portion, and
- a first layer of insulation between the cast internal sub-structure and the first inner skin portion and a second layer of insulation between the second outer skin portion and the second inner skin portion.
