Abstract
An exhaust component assembly includes a heat shield and a mounting structure to attach the heat shield to an outer housing of an exhaust component. The mounting structure includes a primary insulator located between an outer surface of the outer housing and an inner surface of the heat shield, and at least one secondary insulator positioned adjacent the primary insulator. The primary insulator comprises a sheet of material including at least one encapsulated insulating cavity.
Claims24
An exhaust component assembly comprising:
- a heat shield;
- and
- a mounting structure to attach the heat shield to an outer housing of an exhaust component, wherein the mounting structure comprises
- a primary insulator located between an outer surface of the outer housing and an inner surface of the heat shield, wherein the primary insulator comprises a sheet of material including at least one encapsulated insulating cavity, and
- at least one secondary insulator positioned adjacent the primary insulator.
A method of assembling a heat shield to an outer housing of an exhaust component assembly comprising the steps of:
- positioning a primary insulator between an outer surface of an outer housing and an inner surface of the heat shield, wherein the primary insulator comprises a sheet of material including at least one fully encapsulated insulating cavity;
- positioning at least one secondary insulator adjacent the primary insulator;
- and
- placing the heat shield over the primary and secondary insulators such that the heat shield is held fixed relative to the outer housing.
