Zusammenfassumg

Regarding the entire drive train using a combustion engine today is close-coupled to an exhaust gas aftertreatment (EAT) system. Only by using an efficient EAT concept it is possible to attain highest conversion rates and fulfill the emission limits. In doing so it is not only necessary to match the limits for type approval and initial operation but also to guarantee compliance over the engines life time cycle.
