2010 CLEERS Workshop

2010-04-20 - 2010-04-22

Emphasized topic areas:

  • Diesel Particle Filters
  • Selective Catalytic Reduction
  • Lean NOx Traps
  • Oxidation and Reformer Catalysts
  • 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 13th workshop in a series sponsored by the DOE Office of Vehicle Technologies and the DOE Advanced Engine Crosscut Team. The results of the workshop discussions will be documented for the DOE Office of Transportation Technologies (OTT) for consideration in improving R&D priorities and technical focus in DOE-supported transportation programs.

About the 2010 Workshop

The 2010 CLEERS workshop will be hosted by University of Michigan at their Dearborn Campus in Detroit from April 20th – April 22nd, 2010. Diesel particulate filters (DPF), selective catalytic reduction (SCR), lean NOx traps (LNTs), oxidation and reformer catalysts 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.
