2011 CLEERS Workshop
2011-04-19 - 2011-04-21
Emphasized topic areas:
- Diesel Particle Filters
- Selective Catalytic Reduction
- Lean NOx Traps
- Oxidation and Reformer Catalysts
- Hydrocarbon Traps
- Emissions Control Systems Integration
- On-Board Diagnostics
Objectives:
- Share updates and experience on the latest developments for these technologies and corresponding simulation tools
- Enhance emissions control collaboration among industry, government and universities
- Update recognition of key research priorities
Purpose
- CLEERS workshops are intended as 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 14th workshop in a series sponsored by the DOE Office of Vehicle Technologies and the DOE Diesel Crosscut Team. The results of the workshop discussions 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 the 2011 Workshop
- The 2011 CLEERS workshop will be hosted by University of Michigan at their Dearborn Campus in Detroit from April 19th through 21st, 2011. Diesel particulate filters (DPF), selective catalytic reduction (SCR), lean NOx traps (LNTs), oxidation and reformer catalysts, hydrocarbon traps and emissions control systems integration will be the major discussion themes. 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 and an invited panel of experts in integrated vehicle systems simulation. Contributed presentations of 20-30 minutes are also invited from interested parties. Those who are interested in making such presentations should contact one of the following topical coordinators:
