  1. Emissions SolutionsSEDC 2007 Annual Meeting Presented by Brett Alkins Emissions Territory Manager

  2. Caterpillar’s Path to Emissions Reductions • Emissions Repowers • Upgrading Older Engines • Aftertreatment

  3. Emissions Repowers • Tier 1, Tier 2, and Tier 3 Engines • NOx, PM, HC, and CO Reducing Solution • 100+ Machine Models Available Over 2100 Emissions Repowers Completed!

  4. Benefits of Emissions Repower • 285HP Example, i.e. a medium bulldozer at landfill • Replace 1989 engine with a Tier 1 engine • ½ ton per year of NOx reduced • Almost 1 ton per year of additional emissions reduced (HC, CO, PM) • Cost Effectiveness • $40,000/ (1.5ton*6 years) = <$5,000/ton emissions reduced • Primary non-road retrofit technology implemented in California and Texas over last 6 years

  5. Customer Perspective: Wright Bros., TN • Learned of emissions opportunity via ARTBA and TDOT outreach • Wright Brothers, Caterpillar and Stowers partnered to provide ARTBA with retrofit experience in TN • 4 Oxidation Catalysts • 3 Scraper Repowers • 1 Track-type Tractor Repower

  6. Equipment Owners See the Value • Newer Technology • Proven Components • Same reliability, durability, and serviceability • Longer life, more productive • Increased Machine Value • Results from California equipment auction, Tier 0 Equipment • In Dec. 2005, 657B sold for $105,000 • In Dec. 2006, 657B sold for $32,000 • In May 2007, price dropped below $30,000 • Wright Brothers plans on 4 more scraper Tier 2 repowers!

  7. Emissions Retrofit Engine Upgrade GroupsUpgrade to Tier 1 emissions levels during engine overhaul • Cost effective solutions • Same Caterpillar reliability and serviceability • Available for select 3306 off-road applications • Available for 3406 off-road applications in 2007 • EPA Verified, same benefits as engine repower! Turbochargers Fuel Pumps/ Governors Cylinder Packs

  8. Reducing Particulate Matter Emissions in Cat Machines • The Diesel Particulate Filter High filtration efficiency, but.. • Space Claim & Weight • Backpressure (fuel economy) • Cost ($$$) ? Considerable engineering required to ensure an optimum retrofit design.

  9. Aftertreatment Success/Opportunities • Passive DPF’s have survived over 6,000 hours operating in the field • CAT Engineered and CAT Dealer Installed • Active DPF’s that are flexible to various application requirements are being evaluated • Regen on demand, needs to be operator transparent • Retrofittable NOx aftertreatment strategy will depend on technical, commercial and regulatory issues

  10. Conclusions • CAT is actively engaged in providing emissions retrofit products, but only when they can meet our standard of excellence • Engine Repowers and Emission Upgrade kits are an excellent path to reduce NOx, PM, CO and HC • Incentives and outreach are key to spurring interest and gaining customer acceptance • We continue to assess the latest technological advances to cost-effectively reduce emissions in existing machines
