  10. Aftertreatment Absorption of Nox, PM & HC emissionsduring normal operationPeriodically add detergent (diesel fuel) and squeeze

  11. Soot filter traps all soot particles and hydrocarbon. It needs to burn off the trapped soot particles. A key measure of its performance is the balance point temperature. The balance point temperature varies from engine to engine. Balance point temperature: the engine operating condition and the exhaust temperature where soot burn off rate is greater than or equal to the engine soot output.

  12. NOx Adsorber - How Does It Work? It works in three simplified steps: 1. It stores NOx with normal diesel exhaust (Lean). 2. It releases NO2 when it is starved of O2 (Rich). 3. Under the rich condition, CO, HC, and H2 reduce the released NO2 into N2.

  13. Fuel

  14. Low-Emitting Diesel Engines and Vehicles Become a Clean Air Solution • Equivalent or better emissions than gasoline or alternative fuels • Still more fuel efficient with lower greenhouse gas emissions • Performance and reliability that customers depend on

  15. Implications of the Low-Emitting Diesel Technology Road Map • Technology can be applied to all engines: • Heavy-duty trucks, buses • Light-duty vehicles • 2004 technology is foundation for 2007 • Some 2007 technology is available today • Use of 2007 technology requires ultra-low-sulfur fuel • Widespread supply of ULSF is crucial to this technology, now and in 2007

  16. Technology Roadmaps Gone Wild

  17. Conclusions • Design and operation of diesel engines will be evolutionized for 2007 for HD and LD • Aggressive aftertreatment will be production-feasible for NOx and PM by 2007 • Ultra-low-sulfur diesel fuel is the technology enabler to move to near-zero emissions targeted by EPA/CARB
