Catalyzed DPF Emissions

Ultra low sulfur diesel with a catalyzed diesel particulate filter offers the following benefits:

y>90 - 98% PM reductiony>70 - 90% CO reductiony> 90% HC reductiony>90% air toxics & ozone precursor reductiony0 – 5% NOx reduction

Durability & Reliability

Third Round Summary, Ralphs Fleet

y CDPF Technology is transparent to the end user

y 6 out of the ten filters have not been cleaned as of March 2003 and accumulated over 300,000 miles

y Those that were cleaned accumulated over 250,000 miles (2 years of operation)

y No fuel penalty observed

y Significant Emission reductions have been maintained after 3 years of operation

Fleet Conversions

! Plan ULSD conversion ahead of retrofitting vehicles

! It is not necessary to pump out existing diesel product. No special tank cleaning is required.

! Plan three tank turns at the site to make the conversion to ultra low sulfur
