Exhaust Emissions Science Laboratory
The Pacific Northwest National Laboratory's (PNNL) Exhaust Emissions Science Laboratory (EESL) is a research center intended to support the mission of DOE's Office of Advanced Automotive Technologies, specifically the Multi-Laboratory Heavy Vehicle Emissions Reduction Program.
Using the EESL, PNNL researchers are applying their expert capabilities in the areas of surface chemistry, catalyst mechanisms, models, material synthesis, and aerosols to the problem of diesel engine exhaust emissions abatement. The principal activities conducted in the EESL are
- probing and understanding performance-limiting nanometer to micrometer scale phenomena in aftertreatment devices
- experimentation and modeling focused on mesoscale aspects of emissions reduction technology
- the use of unique analytical observatories to characterize each emissions phenomenon
- rapid materials innovation and evaluation of parameters specific to each aftertreatment approach
- the use of an integrated approach covering mechanism investigation, modeling, and materials/system optimization, leading to validation in engine/dynamometer tests.
