Emissions and Emission Controls

Catalyst Modeling and CLEERS

A large part of ORNL’s efforts in catalyst research are geared toward model development of catalyst devices and engine systems.  Experimental data supports the development of computer simulations or “models” of the catalyst devices under a wide range of operating parameters associated with vehicle driving.  In turn, industry uses the models to design engine systems and control strategies on computer systems which saves cost and improves development as compared with processes that rely solely on experiment-based techniques.

Further, ORNL plays a leading role in the CLEERS (Cross-Cut Lean Exhaust Emissions Reduction Simulations) research project where industry, university, and national laboratory researchers meet and collaborate in the effort to build catalyst models.
