Title:
Heat insulation component parts for exhaust air systems
Document Type and Number:
Japanese Patent JP6157479
Kind Code:
B2
Abstract:
A component of an exhaust system for an internal combustion engine. The component comprises an exhaust system structure having an interior through which exhaust gases flow and an exterior, and a thermal insulating wrap for thermally insulating at least a portion of the exterior of the exhaust system structure. The thermal insulating wrap comprises an aqueous mixture comprising an inorganic binder and inorganic filler particles, and a fabric comprising inorganic fibers. The fabric is impregnated with the aqueous mixture so as to form a pliable binder wrap. The pliable binder wrap is wound completely around at least a portion of the exhaust system structure. It can be desirable for the component to further comprise at least one thermal insulator comprising inorganic fibers, where the thermal insulator is disposed between the pliable binder wrap and the exterior of the exhaust system structure.
