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.

Specific sub-objectives are:

• To promote development of performance models for emissions control components such as exhaust manifolds, catalytic reactors, and sensors.
• To provide a consistent framework for sharing information and making timely, informed choices among emissions control technologies.
• To identify R&D needs and priorities and provide endorsements for critical projects.

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.

The Diesel Cross-Cutting Technology Development Team (known as the Diesel Cross-Cut Team for short) is composed of representatives from U.S. diesel engine manufacturers, automotive companies, the Department of Energy (DOE), the U.S. Army Tank Command (TACOM), and the Environmental Protection Agency (EPA). The primary function of the Cross-Cut Team is to coordinate development efforts for advanced, low-emission, high-efficiency compression-ignition-direct-injection (CIDI) engines. This role includes identification and prioritization of specific R&D projects appropriate for government funding.

The Diesel Crosscut Team provides a direct interface between the automotive and diesel engine manufacturers and includes members from the Partnership for a FreedomCAR Advanced Combustion & Emission Control Team and the Diesel Engine Development Team. This organizational structure provides a mechanism for efficient and productive interactions among industry, government, and national labs in addressing strategic energy and emissions control issues now facing the U.S. transportation sector.
