VEHICLE EXHAUST SYSTEM WITH RESISTIVE PATCH |
摘要 |
A vehicle exhaust system includes an exhaust component having an outer surface and an inner surface that defines an internal exhaust component cavity. At least one hole is formed in the exhaust component to extend through a wall of the exhaust component from the outer surface to the inner surface. A member is formed from a resistive material and is configured to overlap the at least one hole. At least one spacer is configured to space the member away from the inner or outer surface of the exhaust component to create an open cavity between the member and the exhaust component. In one example, an actuator is configured to cover and uncover the member dependent upon an operating characteristic to vary damping. |
