Clean Air
designed to optimize engine performance and acoustic tuning
Vehicle emission control products and systems play a critical role in safely conveying noxious exhaust gases away from the passenger compartment and reducing the level of pollutants and engine exhaust noise to acceptable levels. Precise engineering of the exhaust system – which extends from the manifold that connects an engine’s exhaust ports to an exhaust pipe, to the catalytic converter that eliminates pollutants from the exhaust, and to the muffler that modulates noise emissions – leads to a tuned engine sound, reduced pollutants, and optimized engine performance. Emissions and Clean Air Solutions benefits from stricter emissions standards.
Catalytic converters
The catalytic converter is a vital component of a vehicle’s emission control system, responsible for reducing harmful pollutants and emissions from exhaust gases. A catalytic converter uses a catalyst to convert pollutants in the exhaust gases into harmless substances. It is typically located between the engine and the muffler, and its primary function is to reduce the emissions of CO, HC, and NOx. The catalytic converter uses a catalyst, typically made from precious metals such as platinum, palladium, and rhodium, to facilitate chemical reactions that convert pollutants into harmless substances.
Diesel oxidation catalysts (“DOC”)
Devices consisting of a substrate coated with precious metals enclosed in a steel casing used to reduce harmful gaseous emissions such as carbon monoxide emitted from diesel engines.
Diesel particulate filters (“DPF”)
Devices to capture and regenerate particulate matter emitted from diesel engines.
Lean NOx traps (“LNT”)
Devices which reduce nitrogen oxide (“NOx”) emissions from diesel powertrains using capture and store technology.
Selective catalytic reduction (“SCR”) Convertor
Convertors which reduce NOx emissions from diesel powertrains using urea mixers and injected reductants such as Verband der Automobil industrie e.V.’s AdBlue® or Diesel Exhaust Fluid (“DEF”).
SCR-coated diesel particulate filters (“SDPF”)
Lightweight and compact devices combining the SCR catalyst and the particulate filter onto the same substrate for reducing NOx and particulate matter emissions.
Three-way catalysts (“TWC”)
Systems comprising a catalyst encased in a steel shell to reduce the carbon monoxide, hydrocarbons and NOx from gasoline and compressed natural gas (“CNG”) engine emissions.
Mufflers and resonators
Devices to provide noise elimination and acoustic tuning.
Pipes
Utilized to connect various parts of both the hot and cold ends of an exhaust system.
