2013 CLEERS Workshop

2013-04-10 - 2013-04-12

Emphasized topic areas:

  • Diesel Particle Filters
  • Selective Catalytic Reduction
  • Urea Spray Modeling
  • Oxidation and Reforming Catalysts
  • Hydrocarbon Traps
  • Multi-Functional Catalysts and Aftertreatment Devices
  • Emissions Control Systems Integration
  • Engine-Aftertreatment Component Interactions
  • Low-Temperature Catalysis
  • Interpretation of Experimental Aftertreatment Measurements
  • Development of Micro-Kinetic and Global Reaction Mechanisms
  • Computational Model Robustness
  • Engine Exhaust Speciation
  • Particulate Emissions Characterization


  • Share experience on the latest developments for aftertreatment technologies and corresponding simulation tools
  • Enhance emissions control research collaboration among industry, government and universities
  • Identify key research priorities


This is the 16th workshop in a series sponsored by the DOE Office of Vehicle Technologies and the DOE Advanced Engine Crosscut Team. CLEERS workshops are informal, focused forums for sharing recent research results on lean and advanced engine emissions controls and their simulation. Participation by researchers in government, universities, and industry is welcome. Workshop discussions will be summarized for the DOE Office of Transportation Technologies (OTT) and the Advanced Engine Crosscut Team for consideration in improving priorities and technical focus and maximizing leveraging in DOE and industry-supported R&D.

About the 2013 Workshop

As with prior CLEERS workshops, this will be a public meeting open to all those who are interested in understanding and simulating the performance of exhaust emission control devices under realistic conditions. The workshop agenda will include invited presentations by internationally prominent researchers and an invited panel of experts from industry. The industry panel discussion this year will focus on the emissions control challenges associated with increasingly lower exhaust temperatures from advanced combustion engines. Contributed oral presentations of 20-30 minutes and posters are also invited.  Those who are interested in making oral or poster presentations should contact one of the following coordinators:
