Abstract: An exhaust system for the discharge of exhaust gases from a vehicle engine includes a resonator. The resonator comprises a resonator body having at least one, and preferably more than one, elongated composite strip. Each composite strip has a center foil which is corrugated to provide alternate ridges and grooves and is sandwiched between two perforated foils to provide a multiplicity of parallel fluid passages between the corrugated foil and the perforated foils. The composite strips are tightly wound about a central axis parallel to the fluid passages. A housing encloses the resonator body and has an inlet at one end of the fluid passages and an outlet at an opposite end of the fluid passages. The exhaust gases flow through the passages causing a break up and tuning of the sound waves in the system.

Abstract: A highly porous substrate is provided using an extrusion system. More particularly, the present invention enables the production of a highly porous substrate. Depending on the particular mixture, the present invention enables substrate porosities of about 60% to about 90%, and enables advantages at other porosities, as well. The extrusion system enables the use of a wide variety of fibers and additives, and is adaptable to a wide variety of operating environments and applications. Fibers, which have an aspect ratio greater than 1, are selected according to substrate requirements, and are typically mixed with binders, pore-formers, extrusion aids, and fluid to form a homogeneous extrudable mass. The homogeneous mass is extruded into a green substrate. The more volatile material is preferentially removed from the green substrate, which allows the fibers to form interconnected networks. As the curing process continues, fiber to fiber bonds are formed to produce a structure having a substantially open pore network. The resulting porous substrate is useful in many applications, for example, as a substrate for a filter or catalyst host, or catalytic converter.

Abstract: This invention is a light weight, high heat resistant composite exhaust, header/tubing system for an internal combustion system constructed out of fiber and resin. The carbon fiber composite exhaust, CMX invention employs fibers and resin, but is not limited to carbon fiber and alumina-silicate resin. To accomplish the objectives of the present invention, the fiber system is first molded into the desired component by using a collapsible apparatus. Secondly, a single layer of fiber material such as, but not limited to, carbon is applied to uniformly cover the component. Third, the resin is evenly coated by brushing, injection, or squeezing method, and is pushed through the uniform weave. Thus, when the resin has been converted to a ceramic by means of the firing process, the mold can be removed to reveal the first layer of the composite. In order to achieve the desired stiffness and rigidity the following steps must be performed a number of times, depending on the application that will use the exhaust component.

Abstract: An exhaust manifold is provided having ceramic inner layer that is highly resistant to cracking from thermal cycling. In a preferred embodiment, the ceramic inner layer is slip cast from a slip composition having a major amount of fused silica which has an amorphous structure. The manifold also has a ceramic insulation layer, a strain isolation layer and an outer structural layer in various embodiments. According to one embodiment, the strain isolation layer is provided in the form of an intumescent mat that expands on heating and contracts on cooling up to a certain crossover temperature, above which it loses the ability to contract on cooling. In a preferred embodiment, a catalyst-coated support body is provided in the exhaust manifold. As exhaust gases pass through the manifold, noxious components of the exhaust gases begin to convert to environmentally benign species via the catalyst prior to reaching the catalytic converter. Methods of making an exhaust manifold also are provided.
