Tenneco Inc. designs, manufactures, and sells clean air and ride performance products and systems for light vehicle, commercial truck, off-highway, and other vehicle applications. The company serves both original equipment manufacturers (OEMs) and the repair and replacement markets, or aftermarket markets worldwide through major brands, including Monroe, Rancho, Clevite Elastomers, Marzocchi, Axios, Kinetic, and Fric-Rot ride performance products; and Walker, XNOx, Fonos, DynoMax, Thrush, and Lukey clean air products. As a parts supplier, the company produces individual component parts for vehicles, as well as groups of components that are combined as modules or systems within vehicles. These parts, modules, and systems are sold globally to various major OEMs, commercial truck and off-highway engine manufacturers, and aftermarket distribution channels. Clean Air Systems The company designs, manufactures, and distributes various products and systems designed to reduce pollution and optimize engine performance, acoustic tuning, and weight, including the following: Catalytic Converters and Diesel Oxidation Catalysts: Devices consisting of a substrate coated with precious metals enclosed in a steel casing used to reduce harmful gaseous emissions, such as carbon monoxide. Diesel Particulate Filters (DPFs): Devices to capture and regenerate particulate matter emitted from diesel engines. Burner Systems: Devices, which combust fuel and air inside the exhaust system to create extra heat for DPF regeneration, or to improve the efficiency of selective catalytic reduction (SCR) systems. Lean Nitrogen Oxide (NOx) Traps: Devices, which reduce NOx emissions from diesel powertrains using capture and store technology. Hydrocarbon Vaporizers and Injectors: Devices to add fuel to a diesel exhaust system to regenerate diesel particulate filters or Lean NOx traps. SCR Systems: Devices, which reduce NOx emissions from diesel powertrains using injected reductants, such as Verband der Automobil Industrie e.V. (AdBlue) or diesel exhaust fluid. Alternative NOx Reduction Technologies: Devices, which reduce NOx emissions from diesel powertrains, by using alternative reductants, such as diesel fuel, E85 (85% ethanol, 15% gasoline), or solid forms of ammonia. Mufflers and Resonators: Devices to provide noise elimination and acoustic tuning. Fabricated Exhaust Manifolds: Components that collect gases from individual cylinders of a vehicle’s engine and direct them into a single exhaust pipe. Fabricated manifolds could form the core of an emissions module that includes an integrated catalytic converter (maniverter) and/or turbocharger. Pipes: Utilized to connect various parts of both the hot and cold ends of an exhaust system. Hydroformed Assemblies: Forms in various geometric shapes, such as Y-pipes or T-pipes, which provide optimization in both design and installation as compared to conventional pipes. Hangers and Isolators: Used for system installation and elimination of noise and vibration, and for the improvement of useful life. Aftertreatment Control Units: Computerized electronic devices that utilize embedded software to regulate the performance of active aftertreatment systems, including the control of sensors, injectors, vaporizers, pumps, heaters, valves, actuators, wiring harnesses, relays, and other mechatronic components. For the catalytic converters that the company sells, it either buys completed catalytic converter systems or procures substrates coated with precious metals, which the company incorporates into full systems. The company supplies its clean air offerings to 28 light vehicle manufacturers for use on approximately 225 light vehicle models, including 7 passenger car models produced in Europe and 7 light truck models produced in North America for 2013. It also supplies clean air products to 25 manufacturers of commercial truck, off-highway, and other vehicles, including Harley-Davidson, BMW Motorcycle (BMW), Scania, Daimler Trucks, Caterpillar, John Deere, Deutz AG, Kubota, CNHTC, FAW Truck, and Weichai Power. In the aftermarket, the company manufactures, markets, and d
