Zusammenfassung

Upcoming future regulations for EUVII will require a significant reduction of NOx emissions at the tailpipe of heavy-duty Diesel engines. Achieving such demands will not only require a considerable improvement of the efficiency of the selective catalytic reduction (SCR), but also optimal performance under a majority of operating conditions. This, however, must not be at the expense of the overall fuel consumption, to limit CO2-emissions and to achieve a beneficial total cost of ownership (TCO). Such goals can only be achieved by a mix of different measures and require ample improvements to the current configuration of the EUVI aftertreatment system. This paper addresses the system development steps applied to the current aftertreatment system of a heavy-duty EUVI Diesel engine...
