Cross-Cut Lean Exhaust Emissions Reduction Simulations (CLEERS)
CLEERS is a R&D focus project of the Diesel Cross-Cut Team. The overall objective is to promote development of improved computational tools for simulating realistic full-system performance of lean-burn engines and the associated emissions control systems.
With the CLEERS simulation tools, the Diesel Cross-Cut Team aims to:
- Promote the development of performance models for emissions control components such as exhaust manifolds, catalytic reactors, and sensors.
- Provide a consistent framework for sharing information and making timely, informed choices among emissions control technologies.
- Identify R&D needs and priorities and provide endorsements for critical projects.
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.
CLEERS is coordinated by a subcommittee of industry, government, and academic representatives reporting to the Diesel Cross-Cut Team. Sponsored activities include a website and technical exchange workshops.
