8th CLEERS Workshop

2005-05-17 - 2005-05-19

Emphasized topic areas:

  • Diesel Particle Filters
  • Selective Catalytic Reduction
  • Lean NOx Traps
  • Synergies between these three components in actual systems


  • Provide technical updates on the latest developments for these technologies and corresponding simulation tools
  • Enhance emissions control collaboration among industry, government and universities
  • Improve and update recognition of key research priorities


CLEERS workshops are intended as relatively informal but tightly focused forums for sharing recent research results on understanding and simulating lean exhaust emissions control. Joint participation by researchers in government, universities, and industry is encouraged. This is the 8th workshop in a series sponsored by the DOE Office of FreedomCAR and Vehicle Technologies and the DOE Diesel Crosscut Team. The results of the workshop discussions, especially the all-participant discussion at the end, will be documented for the DOE Office of Transportation Technology (OTT) for consideration in improving R&D priorities and technical focus in DOE-supported transportation programs.

About Workshop 8

The 8th CLEERS workshop will be hosted by University of Michigan at their Dearborn Campus in Detroit from May 17th through 19th, 2005. Diesel particulate filters (DPF), selective catalytic reduction (SCR) and lean NOx traps (LNT’s) will be the major discussion themes, but it is also anticipated that there will be important updates on synergies among these components in actual systems. As with the previous CLEERS workshops, this will be a public meeting open to all who are interested in the most recent developments in understanding and simulating the performance of these devices under realistic conditions.

The workshop agenda will include invited presentations by internationally prominent researchers. Contributed presentations of 20-30 minutes are also invited from interested parties.
