2019 CLEERS Workshop

September 17 - September 19


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 laboratories; and
  • identify the most pressing pre-competitive research priorities for emissions control.

CLEERS Workshops feature invited presentations by internationally prominent researchers and a moderated discussion with an invited panel of industry experts.

Workshop participants are encouraged to contribute oral presentations and posters on the following (or related) technologies and topics.

Topic Areas


  • Passive NOx adsorbers (PNA)
  • Hydrocarbon traps
  • Selective catalytic reduction (SCR) of NOx by urea/ammonia
  • Oxidation catalysts (DOC, MOC, etc.)
  • Three-way catalysts (TWC)
  • Diesel and gasoline particulate filters (DPF, GPF)
  • Selective catalytic reduction of NOx by hydrocarbons (HC SCR)


  • Identification of reaction mechanisms (from micro-kinetic through global) and kinetic parameters
  • Modeling strategies for improved accuracy and/or reduced computation time
  • Drive cycle simulations of advanced vehicle/emissions control systems
  • Formulation, evaluation, and simulation of catalysts with lower operating temperatures
  • Multifunctional aftertreatment devices: catalyst coated filters, layered/zoned washcoats
  • Integration of engines and emissions controls
  • Durability
  • Reductant (urea or fuel) delivery: spray modeling, decomposition processes, deposit formation

The 2019 CLEERS Workshop will be held September 17-19, 2019 at the Sheraton Ann Arbor
