发明名称 ENCLOSURE MEMBER FOR EXHAUST PIPE
摘要 PURPOSE:To obtain excellent heat insulating ability, noise eliminating ability and vibration damping ability, by forming an enclosure member from the lamination of wire netting and fiber mat, and enclosing the exhaust pipe system of an internal combustion engine with the enclosure member. CONSTITUTION:An enclosure member for an exhaust pipe is formed from the lamination 1 of a wire netting 2 and a fiber mat 3. For example, the fiber mat 3 is inserted into the knitted cylindrical wire netting 2, and this is compressed and flattened to form the enclosure member. And the fiber mat 3 is provided with holes 4 with which the fiber mat 3is fixed to the wire netting 2. The fiber mat 3 is made of a heat resistant fiber, for example, asbestos, ceramic fiber,and so on. This enclosure member is, for example, used to enclose the exhaust pipe system of the engine of an automobile. Namely, the lamination 1 is wound around the exhaust pipe system which comprises a dual front pipe 5, a catalytic converter 6, a tail pipe 7, a muffler 8, and so on.
