SCR Systems

The harmful nitric oxide excretion, which is the main problem in diesel engines, is greatly reduced by SCR technology (selective catalytic reduction technology) and converted into water vapor and nitrogen with the help of a urea solution called AdBlue®. AdBlue® is carried in an additional tank in commercial vehicles and injected into the exhaust system. Specially developed dosing systems in the exhaust system, together with the SCR catalyst, reduce nitric oxide excretion by 85% and soot particles by 40%. Today, reducing the particulate and nitric oxide excretion at the same time and thus meeting the legally demanded limit values can only be achieved with the SCR method.
