        EPA and Ford to Develop Clean Diesel Combustion Technology
          The U.S. Environmental Protection Agency (EPA) and Ford
          Motor Company have announced a second phase of their
          technology partnership to develop a new diesel emission
          technology called Clean Diesel Combustion (CDC).
          Phase II of the Cooperative Research and Development
          Agreement (CRADA) will further refine the technology and examine its commercial
          viability.

          Clean Diesel Combustion, which was invented in EPA's National Vehicle and Fuel
          Emissions Laboratory in Ann Arbor, Michigan, holds promise for providing another
          pathway for diesel engines to meet the stringent EPA Tier 2-bin 5 nitrogen oxide
          (NOx) emission levels. Results so far indicate that Clean Diesel Combustion may
          meet the new standards while maintaining the excellent fuel economy, performance,
          and reliability of diesel engines.

          Clean Diesel Combustion shows important progress towards the program goal of
          meeting the upcoming diesel emissions standards without additional NOx
          aftertreatment.
                              Clean Diesel Combustion technology is the combination of
                              several innovative improvements in diesel fuel injection
                              system performance, reoptimization and refinement of air
                              management and turbocharging systems, and an improved
                              combustion system.
          Ford and EPA are making significant investments in advancing CDC technology,
          starting with an evaluation for diesel engines sized for the truck market.

          Clean, efficient, advanced technology diesel engines have the potential to reduce
          the nation's dependence on petroleum while meeting new exhaust emissions
          requirements. This is a plus for consumers who prefer diesel's performance and
          25-40 percent fuel economy benefit over gasoline engines.
