CLEERS Workshops are annual meetings open to all those who are interested in understanding and simulating the performance of exhaust emission control devices under realistic operating conditions. The Workshops provide an informal, focused forum to:

  • share recent experimental and computational simulation experience with advanced aftertreatment technologies;
  • enhance emissions control research collaborations among industry, universities, and DOE national labs; and
  • identify the most pressing pre-competitive research priorities for emissions control.

Presentations from prior CLEERS Workshops are available below.
