Abstract

An exhaust manifold for use with an internal combustion engine, the exhaust manifold including a body, one or more fluid passageways defined by the body, a valve in fluid communication with at least one of the one or more fluid passageways, the valve being adjustable between an open configuration and a closed configuration, a mounting bracket supported by the body, and an actuator in operable communication with the valve and configured to adjust the valve between the open and closed configurations, and wherein the actuator is coupled to the mounting bracket.

Claims

1. An exhaust manifold for use with an internal combustion engine, the exhaust manifold comprising:

a body;

one or more fluid passageways defined by the body;

a valve in fluid communication with at least one of the one or more fluid passageways, the valve being adjustable between an open configuration and a closed configuration;

a mounting bracket supported by the body; and

an actuator in operable communication with the valve and configured to adjust the valve between the open and closed configurations, and wherein the actuator is coupled to the mounting bracket.

2. The exhaust manifold of claim 1, wherein the mounting bracket is formed integrally with the body.

3. The exhaust manifold of claim 1, further comprising a thermal isolator coupled to one of the actuator and the mounting bracket.

4. The exhaust manifold of claim 3, wherein the thermal isolator includes one of a heat shield and a spacer.

5. The exhaust manifold of claim 3, wherein the thermal isolator is a heat shield, wherein the heat shield defines a storage volume, and wherein the actuator is at least partially positioned within the storage volume.

6. The exhaust manifold of claim 3, wherein the thermal isolator at least partially defines a fluid jacket therein.

7. The exhaust manifold of claim 3, wherein the thermal isolator is a spacer positioned between the actuator and the mounting bracket.

8. The exhaust manifold of claim 1, wherein the mounting bracket includes a first set of mounting points and a second set of mounting points, and wherein the actuator is coupled to the mounting bracket via the first set of mounting points, and wherein a heat shield is coupled to the mounting bracket via the second set of mounting points.

9. An exhaust manifold for use with an internal combustion engine, the exhaust manifold comprising:

a body including a mounting bracket, the mounting bracket including a first set of mounting points;

one or more fluid passageways defined by the body;

a valve in fluid communication with at least one of the one or more fluid passageways, the valve being adjustable between an open configuration and a closed configuration;

an actuator in operable communication with the valve and configured to adjust the valve between the open and closed configurations, and wherein the actuator is coupled to the first set of mounting points; and

a thermal isolator coupled to one of the actuator or the mounting bracket.

10. The exhaust manifold of claim 9, wherein the mounting bracket is formed integrally with the body.

11. The exhaust manifold of claim 9, wherein the thermal isolator is a heat shield, wherein the heat shield defines a storage volume therein, and wherein at least a portion of the actuator is positioned within the storage volume.

12. The exhaust manifold of claim 9, wherein the thermal isolator is a spacer positioned between the actuator and the mounting bracket.
