Zusammenfassung
The application of a Selective Catalytic Reduction (SCR) coating on a Diesel particulate filter (DPF) has the potential to enable the Off-Highway sector to meet the increasingly strict future emissions legislations, whilst allowing more flexibility with regards to packaging space for the overall powertrain design and system architectures. The incorporation of the SCR coating on the filter enables the potential for achieving stricter emissions limits with a reduced installation space allowing more flexibility in the overall system design as well as achieving legislation limits over a wide range of duty cycles. Optimizing the layout and control of these systems also allows OEMs to certify systems, either passively or actively, over multiple markets with varying legislation types.
