10 Aftertreatment Absorption of Nox, PM & HC emissions during normal operation Periodically 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 NO x Adsorber - How Does It Work? It works in three simplified steps: 1. It stores NO x with normal diesel exhaust (Lean). 2. It releases NO 2 when it is starved of O 2 (Rich). 3. Under the rich condition, CO, HC, and H 2 reduce the released NO 2 into N 2.

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

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