Summary

To ensure the future mobility worldwide and to enable the economy growth especially in the emerging markets the diesel power train will remain the key technology. This will require robust solutions especially for commercial applications. On the other hand, truck and off-road engines are facing significant emission reduction requirements especially with the coming Euro6 and Tier4 legislation. The initial solution for Tier4 will be to achieve the emission reduction by excessive aftertreatment using SCR technology and DPF systems with active regeneration. However, the initial cost, handling and packaging of such systems is a disadvantage for the end user. The biggest potential to reduce the system complexity is to lower the effort on the aftertreatment side. Therefore, further engine-out emission reduction and fuel consumption reduction is required.
