Internal combustion engines emit large amounts of nitrogen oxides. Selective Catalytic Reduction (SCR) technology is the most powerful of all measures to reduce nitrogen oxides and can reduce emissions to very low levels. For this purpose, an additional liquid (AdBlue) is injected into the exhaust line after the turbocharger and vaporises on the way to the catalyst. There, the AdBlue converts the nitrogen oxides on the catalyst to nitrogen and water, both natural and completely non-toxic components. The metered amount of AdBlue and its distribution over the catalyst determines the efficiency of the system quite decisively.
AIR-SONIC offers different solutions optimized for the specific application. As a manufacturer and supplier of the entire exhaust system, customers benefit from a result that considers the emissions as a whole and offers a tailor-made solution that is optimally tailored to the requirements.
